Product Spotlight: Hertz SPL Show Neo

SPL Neo

If you enjoy cranking your music, the SPL Show Neo speakers from Hertz might be the perfect solution for your car, truck or motorcycle. Designed with ultra-compact, high-flux neodymium magnets, these speaker solutions are capable of delivering rock-concert volume levels to ensure you hear every part of your music loudly and clearly.

More-Powerful New Magnets

The Hertz SPL Show line has been upgraded with new, stronger neodymium magnets. These N38H magnets are rated for high-temperature applications to ensure the speakers will continue to sound great for years, even after prolonged use at high output levels.

Hertz has designed each of the new SPL Show speakers with weather-resistant materials and properties to ensure they can withstand prolonged exposure to rain and the sun’s UV rays. The motor assemblies are treated with a corrosion-resistant electro-coating using a process called cataphoresis.

High-Efficiency Bullet Tweeter

The ST 25A Neo is a compact, high-efficiency, high-frequency compression driver that features an aluminum diaphragm mated to a 1-inch copper-clad aluminum ribbon voice-coil. The unit has a nominal impedance of 4 ohms and an amazing efficiency of 107 dB. The driver is rated to handle 100 watts of power when filtered at 5 kHz with a 12 dB/octave crossover. These same drivers are available in the ST 25K Neo kit version with inline passive crossovers and thread-on metal mesh grilles.

The ST 25K Neo Kit includes a pair of compression-driver tweeters, passive crossovers and mesh grilles.

SPL Neo Midrange Drivers

The new Neo line includes 6.5- and 8-inch midrange drivers. Both speakers use a lightweight pressed paper cone that has been treated with a water-repellent coating. Compliance is provided by a double-roll cloth surround and a flat linear spider.

The 6.5-inch SV 165 NEO features a 1.5-inch voice-coil former that is wound to a nominal impedance of 4 ohms. Continuous power handling is rated at 150 watts, with peak power at 400 watts. With a resonant frequency of 120 Hz and an Xmax specification of 1.5 mm, high-pass crossover points around 250 to 300 Hz will ensure maximum output with minimal distortion. Efficiency is specified at 97 dB and the compact neodymium magnet allows for a mounting depth of only 2.25 inches.

The SV 165 NEO midrange driver is a perfect drop-in upgrade for your Harley-Davidson motorcycle.

The larger 8-inch SV 200 NEO uses a taller 1.5-inch-diameter voice-coil to increase Xmax to 2.7 mm and power handling to 200 watts continuous or 500 watts maximum. Efficiency also jumps to a mind-blowing 100 dB. Mounting depth for the 8-inch driver is a manageable 3.3 inches.

With a sensitivity rating of 100 dB, the SV 200 NEO is perfect for high-output applications.

Coaxial High-Efficiency Speaker Solutions

Hertz developed a set of high-output two-way speaker solutions to make upgrading motorcycle audio systems easy, efficient and reliable. The solutions start with the 6.5-inch SX 165 NEO coaxial driver. This two-way speaker features the same weather-treated pressed-paper cone material as the SV 15 NEO. A large-diameter 1.4-inch PEI-dome tweeter provides excellent high-frequency output to beyond 20 kHz. The tweeter is protected with a resettable solid-state protection device to ensure years of reliable operation.

Hertz rates the speaker at being able to handle 100 watts of power when filtered with a high-pass crossover set to 150 Hz at a slope of -12 dB/octave. Peak power handling is 200 watts.

SPL Neo
The SX 165 NEO includes dual terminals to make it easy to daisy-chain multiple speakers together.

For saddlebag speaker applications on touring bikes, the Hertz SX 690 NEO is a great choice. This 6×9-class speaker features a three-way design with a 0.8-inch super-tweeter and a 1.4-inch tweeter. Both high-frequency drivers use Tetolon dome materials and feature the same resettable protection circuit used on the 6.5-inch driver. A rubber surround at the top edge of the weather-treated pressed-paper cone ensures reliability.

Efficiency is specified at 94 dB and Xmax at 5.5 mm. With lots of excursion capability available from the woofer, the SX 690 Neo can easily play down to 100 Hz or lower, depending on your output expectations. Power handling is listed at 130 watts continuous and 260 watts peak.

SPL Neo
Both the SX 690 NEO and the SX 165 NEO feature a flexible seal around the tweeter pole piece to ensure water and debris can’t enter the tight-tolerance voice-coil assembly.

Great Sound with Less Weight

One of the key features of the new NEO speakers is their weight. Compared to their ceramic-magnet brethren, they have much less effect on the handling of your motorcycle. For example, pair of SV 165 NEO weighs 3.96 pounds. A pair of the SV 165.1 comes in at 8 pounds. The SV 200 Neo is 5.3 pounds per pair compared to 12.4 pounds for the SV 200.1.

Turn Your Next Drive into a Concert with Hertz SPL Show Neo Speakers

When it comes time to upgrade the sound system on your motorcycle or side-by-side, or the one in your vehicle, if you want the system to play at extreme volume levels, drop by your local Hertz retailer and ask about the new SPL Show Neo speakers.

Product Spotlight: Hertz Cento Subwoofers

Cento Subwoofers

As a continuation of our look at the Hertz Cento Series, we are going to delve into the features of the new Cento Subwoofers. Available in 10- and 12-inch sizes with either two- or four-ohm voice coil configurations, the Cento subwoofers are a perfect example of trickle-down technology providing amazing value and performance for car audio enthusiasts.

Hertz Cento Subwoofer Physical Features

Cento SubwoofersThe Cento subwoofers are based on a rigid four-spoke basket. Vents in the base of each spoke allow hot air to escape from underneath the spider to provide voice coil cooling. A flat (not cupped) spider is mounted on a plastic spacer at the base of the basket. Spring-loaded wire terminals capable of accepting 8AWG wire are molded into an extension off the side of the spider spacer ring. Additional cooling is provided by vertical vents in the plastic reinforcement ring that is used to attach the voice coil former to the spider and the cone. This ring dramatically increases the glue contact area and helps to ensure each component is aligned perfectly at this crucial triple joint.

The glass fiber voice coil former has a diameter of 35 mm (1.38 inches) and serves as a home to a six-layer copper winding. The result is 300 watts of continuous power handling on the 10-inch CS 250 S2 and C2 250 S4 subwoofers and 350 watts on the 12-inch CS 300 S2 and S4 models. Based on the height of the voice coil windings and the thickness of the top plate, the Hertz Cento subwoofers have an X-max specification of 12.5 mm (one-way).

Cento SubwoofersA one-piece ferrite magnet at the base of the speaker provides magnetic flux. There is no cooling vent in the T-yoke of the Cento subwoofers, so your installer can butt them right up against the back of an enclosure without fear of affecting their performance or reliability. Speaking of mounting requirements, the 10-inch subs require a mounting depth of 4.53 inches and the 12-inch models need 5.12 inches.

The cone and dust cap on the Cento subwoofers are made from polypropylene and are attached to the outer edge of the basket using a rubber surround. An ABS plastic trim and mounting ring around the perimeter of the drive provides a clean and classy appearance once installed. Hertz offers optional protective mesh grilles with part numbers CG 250 and CG 300 to help keep the subs looking like new.

Enclosure Requirements

Cento SubwoofersHertz suggests that the CS 250 S2 and S4 will work in enclosures as small as 0.57 cubic feet and the CS 300 S2 and CS 300 S4 will work in a 1-cubic-foot enclosure. The 10-inch designs result in a system F3 of 55 Hz, and the 12-inch designs have an F3 of just under 50 Hz. For both applications, Hertz recommends implementing an infrasonic high-pass filter at 15 Hz with a slope of 24 dB/octave to prevent damage due to high excursion levels. Based on a quick look at the specifications, your system designer can use these subwoofers in a vented enclosure to provide about 4 dB more output across the board in exchange for increased enclosure volume.

Amazing Bass and Great Value

A single Cento subwoofer is a perfect match for the DPower1 monoblock amplifier, or you could match a pair of them to the HCP 1D monoblock. If you’re in the market for a subwoofer that won’t break the bank but provides low-frequency performance from relatively compact enclosure designs, drop by your local authorized Hertz retailer and ask for a demonstration of the new Cento subwoofers.
