The addition of amplifiers to Sony’s Mobile ES line means that every component in a premium car audio system can come from this prestigious series. Our second amplifier spotlight focuses on the compact and powerful XM-4ES four-channel amplifier. Let’s see what Sony’s development team has created!

Sony Mobile ES XM-4ES Amplifier Specifications

The XM-4ES can drive four 2- or 4-ohm loads in its stereo configuration. Each pair of channels can be bridged to drive a single 4-ohm speaker or subwoofer with significantly more power. This bridged configuration is common in systems with a pair of front component speakers and a single subwoofer in the trunk or cargo area.

By way of power specifications, Sony rates this amp as capable of producing a beefy 100 watts per channel with 4-ohm drivers. That power increases to 165 watts when driving 2-ohm loads. When a pair of channels are bridged, the amp will produce 330 watts into a single 4-ohm load. As we’ve come to expect from a no-nonsense company like Sony, all specifications are compliant with the CTA-2006-C standard for supply voltage, noise and distortion content. The power ratings contain less than 1% total harmonic distortion and noise and are measured with 14.4 volts supplied to the amplifier. The CTA-compliant signal-to-noise ratio is 77 dB, and harmonic distortion is rated as less than 0.05%. Finally, the frequency response is very wide at 10 Hz to 40 kHz. On paper, everything looks excellent.

XM-4ES Features and Design

The chassis of the XM-4ES is the same high-mass 10.63-inch wide, 8.46-inch deep, 2.36-inch tall cast-aluminum heatsink as used on the XM-1ES monoblock we spotlighted recently. All signal, power and speaker connections are made along the front edge of the amp, and all but one of the controls are concealed under a removable panel on top of the amp. It’s worth noting that the center trim panel on top of the amp can be rotated 180 degrees, so the Mobile ES logo is aligned with the amplifier’s orientation in your installation.

The front edge features three beefy terminal blocks with heavy-duty set screws accessible from the top of the amp. The right-hand block will accept four-AWG power and ground wires and the remote turn-on lead. The two center blocks are for the speaker output connections, and they will take 10-AWG speaker cables without fuss. A pair of 40-amp ATC fuses to the left of the power block protect the amp.

On the far left of the end panel is a switch that your installer can use to select between low- and high-input voltages. This indicates that the amp has differential inputs – a feature that should be on all car audio amplifiers. Three pair of RCA jacks are present. Two pair are inputs (one RCA for each amplification channel), and the third is an output that could feed a subwoofer amp.

On top of the amp, two groups of controls are mimicked for each pair of channels. These include input sensitivity, filter function, filter range and both high- and low-pass adjustments. Without getting into too much, it’s worth noting that each pair of channels can operate in full-range, high-pass, low-pass or bandpass filter configurations. The amp also includes remote or a signal sense turn-on detection that can be used in high-level input mode, which is crucial for integration with factory-installed source units. There are also switches for signal summing and line-out mode selections. We have a Test Drive Review planned for this amp in a few months. We’ll cover the details of each control then.

Chassis and Electronic Design

As mentioned in the XM-1ES spotlight, Sony has put extra attention into the design of the amplifier chassis to help reduce resonance and vibration that could deteriorate sound quality and accelerate wear and tear. That’s something I haven’t seen any other manufacturer focus on.

Internally, the amplifier is based on two circuit boards. The main board is home to the power supply and output stage. High-quality, high-tolerance surface-mount components are used wherever possible. The output filter chokes are shielded units that help to reduce electromagnetic interference. The second circuit board stands vertically and has all the signal processing controls and switches. In all, the design is modern and well-organized.

The team here at BestCarAudio.com has been privileged to follow the introduction of new, high-performance car audio components in the Sony Mobile ES line. From their impressive speakers and subwoofers to the genuinely outstanding XAV-9500ES source unit, each solution has delivered exceptional performance and value. For 2022, Sony has added three amplifiers to the Mobile ES line. The first model we’ll spotlight is the XM-1ES monoblock subwoofer amplifier. Let’s dig in!

Sony Mobile ES XM-1ES Amplifier Specifications

The XM-1ES is a monoblock car audio amplifier designed to power subwoofers with up to 1,000 watts of power. Specifically, Sony rates the amp as capable of producing 600 watts of power into a 4-ohm load with specifications that fall under the CTA-2006-C guidelines for noise, distortion and supply voltage. When driving a 2-ohm load, power output increases to 1,000 watts while remaining under the 1% THD+N limit. Sony specs the distortion as being 0.05% or less at 100 Hz. Though it’s uber-geeky, I’m happy to see that the 77 dB signal-to-noise ratio specification is also CTA-compliant. Everyone at BestCarAudio.com is fanatical about proper specification qualifications, and Sony isn’t playing any games in this regard.

The amplifier measures 10.63 inches wide, 8.46 inches deep and 2.36 inches tall. This is small enough to fit under the front seats of many vehicles or in a storage compartment under the floor of a cargo area. Sony has done something unique with the chassis and bottom-plate design of the XM-1ES that I’ve never seen from any other amplifier manufacturer. The high-mass cast-aluminum extrusion has been optimized for a resonant frequency that is well out of the region where most of the vibration energy from the vehicle and subwoofer system occurs. This will contribute to product reliability and could easily improve the amplifier’s sonic performance. It’s also worth noting that the center trim panel on the top of the amp can be rotated 180 degrees, so the Mobile ES logo aligns cosmetically with your installation. This is impressive attention to detail.

In terms of electrical connections, all signal, power and speaker terminals are along the front edge of the amplifier. All the speaker and power connections are made via heavy-duty terminal blocks with hex-head set screws accessible from the top of the amp. Even better, the same size hex key is used for every screw on the amplifier, from the top trim cover to the beefy 1/0 gauge power terminals. Fuses, the connection for the very handsome remote level control and an input voltage selection switch round out the end panel features.

Removing two screws on top of the amp gives your installer access to the amplifier’s configuration settings and controls. RCA input jacks will accept 0.2 to 8V in low-voltage mode and 3 to 16 volts in high-level mode. This switch implies that the inputs on the amp feature a differential design that will help eliminate the presence of induced noise. The low-pass crossover is adjustable from 50 to 500 Hz and has a slope of -24 dB/octave.

The XM-1ES has remote signal detection turn-on capabilities when using the high-level input setting, so it can be used with a factory source unit without needing external hardware in most applications. The infrasonic filter is adjustable from 5 to 50 hertz with the same attenuation rate.

A look inside the amp shows a modern design, using surface-mount components almost exclusively. Surface-mount parts, which can be placed on the board robotically instead of by hand, offer exponentially better value to consumers. These parts also typically offer higher precision than their through-hole brethren. High-quality capacitors, shielded output filter chokes, lots of energy storage and good input filtering are clearly evident.

A small variable-speed fan in the back left corner helps ensure that the amp will continue to function reliably, even when installed in a space with limited ventilation. This durability is part of why Sony can back its Mobile ES amplifiers with a three-year manufacturer’s warranty.

Consumer reception of the new Sony Mobile ES speakers has been incredible. These solutions were designed to offer benchmark performance at very accessible price points. A while back, we looked at the 6.5-inch component set and coaxial speakers. In this BestCarAudio.com spotlight, we’ll check out the features of the XS690ES 6-by-9 and the XS-680ES 6-by-8-inch speaker sets.

Sony Mobile ES XS-690ES

The XS-690ES speaker set is a drop-in replacement for the most popular speaker size of all time – the ubiquitous six-by-nine. Sold in pairs, the set includes mesh grilles for custom installations. These two-way speakers feature a 1-inch soft-dome tweeter and a mica-reinforced cellular aramid fiber matrix woofer cone. The tweeter uses a synthetic fiber diaphragm that balances mass and rigidity to deliver excellent clarity and extension to an as-claimed 40 kHz. The woofer cones are well-damped and rigid to ensure uncolored midrange performance and great bass production. The rubber surround features Sony’s Separated Notch Edge Surround design that helps to damp unwanted oscillations that add distortion at high excursion levels. In addition, Sony notes that the progressive spider is designed to deliver “rapid and precise” control over the woofer for crystal clear performance.

Physically, the speakers are based on a five-beam composite basket that offers both rigidity and excellent damping characteristics. This construction allowed Sony to integrate a cooling system around the ceramic magnet that they call the Dynamic Air Diffuser. As a result, hot air from the voice coil can escape from under the spider to optimize power handling and reduce compression and rarefication at high excursion levels.

In terms of specifications, the XS-690ES speakers are rated to handle 110 watts as per the CTA-2031 specification and efficiency is specified as 90 dB at 1-watt, 1-meter, with a tolerance of 4 dB. When choosing these speakers for upgrades in vehicle doors, note that the mounting depth is 2.875 inches with a protrusion height of just 0.50 inch from the mounting surface. Last but certainly not least, the speakers have a nominal impedance of 3.2 ohms.

Sony Mobile ES XS-680ES

The XS-680ES speakers are explicitly designed as an OE speaker upgrade solution. These drivers share the same five-spoke composite basket with their integrated Dynamic Air Diffuser cooling technology. The woofer cones feature the same balanced-performance mica-reinforced cellular aramid fiber matrix construction. It’s worth noting that the mica mineral not only improves damping but it also increases thermal stability. This physical robustness is crucial around the joint with the voice coil.

Sony has done its homework in terms of delivering smooth output between the midrange and tweeter. Aside from the high-quality polypropylene capacitor that serves as the crossover, the XS-162ES 6.5-inch coaxial speakers and these XS-680ES six-by-eight drivers use the same 13/16-inch (2.0 cm) tweeters. The XS-690ES uses the larger, more efficient 1-inch design used with the XS-160ES component set. The crossover in the component set includes attenuation circuitry, so the output efficiency matches that of the woofer while offering improved low-frequency output.

In the case of all three coaxial driver solutions, the tweeters are mounted atop a custom-tooled composite post that extends up through the center of the driver. The post features a smoothly tapered shape and finned outer edge to help control midrange-information reflections. Likewise, the top of the tweeter is positioned so that it doesn’t extend past the front edge of the woofer surround. Other drivers aren’t always like this, and their tweeters can present issues when mounted behind factory grilles. It’s clear that every square inch of these drivers is optimized for the best possible performance.

The XS-680ES drivers also use a progressive spider at the base of the driver and Sony’s new Separated Notch Edge Surround for compliance at the top of the cone. In terms of specs, power handling is rated at 75 watts (CTA-2015 compliant), efficiency at 89 dB with a tolerance of 4 dB, and nominal impedance at 3.2 ohms. The mounting depth for these six-by-eight speakers is 2.125 inches.

Distortion-Reducing Shorting Ring

With respect to both the XS-680ES and XS-690ES, we’ve already mentioned the woofer cone material as well as the notched surround as crucial factors in delivering clear sound at high volume levels. However, another vital feature that Sony included is an aluminum shorting ring inside the motor assembly. This seemingly simple addition helps damp unwanted magnetic fields that are created as the voice coil moves forward and rearward from rest. Those fields would oppose the efforts of the fixed ceramic magnet and dramatically reduce output at the top end of the midrange and add distortion. The aluminum shorting ring, quite simply, acts as a short-circuit to those unwanted high-frequency magnetic currents, allowing the drivers to deliver uncannily clear midrange clarity.

If you haven’t heard car audio speakers with this technology, it’s well worth making a special trip to audition them. Quite simply, they sound different and better than speakers that don’t include this technology. Oh, and most products that include shorting rings cost at least twice as much, if not three times.

In the first week of May 2021, Sony Electronics introduced its new Mobile ES series of speakers and subwoofers. If you’ve been into the car audio industry for a while, then you’ll recognize the Mobile ES (Elevated Standard) name from classic products like the CDX-X90 CD player. The new Mobile ES speakers include 6.5-inch coaxial and component sets, a set of 6×8 and 6×9-inch coaxials and a 10-inch subwoofer. Let’s dive into the 6.5-inch sets and explain what makes them an excellent solution for an enthusiast wanting amazing sound from their car audio system.

Sony Mobile ES XS-162ES Speakers

The XS-162ES is a 6.5-inch component speaker set that includes a pair of woofers with removable grilles, a set of 1-inch tweeters and a pair of passive crossover networks. The woofers are based on a proprietary lightweight composite material, designed to integrate cooling vents around the perimeter of the magnet to help keep the motor assembly cool. Sony calls this its Dynamic Air Diffuser. The five-spoke baskets also include venting under the spider mounting plateau to increase linearity at high excursion levels. There are 10 mounting holes in the thick upper flange to accommodate three-, four- and six-position fastener locations. A phase plug in the center of each woofer is supported by a finned aluminum bobbin with its own Dynamic Air Diffuser for added cooling.

The woofers are formed using Sony’s third-generation Mica Reinforced Cellular (MRC) cone material. The mixture combines mica mineral powder to increase damping and thermal stability with aramid fibers to provide good strength and rigidity. Sony reports that this new material helps suppress cone resonances to deliver improved bass and midrange performance. The cone is suspended by a progressive spider that helps control motion at extreme excursion levels. The design of the Separated Notch Edge Surround at the top of the cone, with its curved grooves, reduces distortion by equalizing compliance for inward and outward motion and damping the synthetic rubber material’s resonances.

Speaking of distortion reduction, Sony has included an aluminum shorting ring around the inside of the magnet to help control unwanted magnet flux in the motor assembly. This feature results in a significant reduction in speaker inductance and smoother upper midrange performance.

The set of tweeters included in the system uses a soft-dome design with a large surround. The voice coil is connected directly to the base of the diaphragm. A large neodymium magnet slug serves as the motor for the tweeter. The voice coil is immersed in a magnetic fluid that improves power handling, increases efficiency and damps unwanted resonance.

Sony claims these tweeters deliver output to 40 kHz. As such, they are ideal for Hi-Res source units that can play FLAC and DSD files. The tweeters can be flush-, surface- or angle-mounted using the included hardware.

The passive crossover networks each feature high-quality mylar capacitors and an air-wound inductor. There’s an output level control switch that will allow your installer to attenuate the tweeter by 3 dB to balance the system.

XS-160ES Coaxial 6.5-inch Speakers

The XS-160ES is the coaxial version of the XS-162ES drivers. They share the same basket and woofer design but feature a 13/16-inch soft dome tweeter instead of the 1-inch driver found on the component set. The tweeter is mounted on top of the composite center post and, just like its big brother, includes an integrated waveguide to help increase efficiency. The tweeter crossover capacitor is mounted in the center of the pole extension for a clean and tidy appearance.

An important consideration in choosing a coaxial speaker for your car or truck is to ensure that the tweeter doesn’t protrude too far out the front. The product development team at Sony took this into account and made the top edge of the tweeter even with the top of the woofer surround so it won’t come into contact with the stock grille in your car or truck.

Mounting Requirements and Specifications

Both the XS-160ES and XS-162ES have a mounting depth of 2.125 inches and require a 5-inch cutout diameter. When installed, the grilles stick out 29/32 of an inch. The tweeters in the XS-162ES require a 2.128-inch mounting hole and need 0.75 inch of depth when mounted flush. The overall outer diameter is 2.5 inches. Both speakers are rated for up to 60 watts of continuous and 270 watts peak power handling as per the IEC 60268-5 spec. The CTA-2031 spec is 90 watts per driver. Efficiency is specified at 89 dB with a tolerance of 2 dB at 1 W/1M. The frequency response is 45 Hz to 40 kHz for the XS-160ES and 40 Hz to 40 kHz for the XS-162ES system with no specified tolerance.

Upgrade Your Car Audio Experience with Sony Mobile ES

Based on the feature set alone, the new Mobile ES speakers put themselves in competition with products costing two to three times as much. The new Sony speakers are available to audition and purchase from authorized Sony Mobile ES retailers across the U.S. and Canada. If you’re looking for a way to improve the audio system in your car or truck dramatically, the XS-162ES and XS-160ES speakers are a great option.
