TeamZXM8/4 8" 1x4Ohm SVC 400WRMS Ultimate High SPL Midrange/Midbass Speaker For Custom Installations

World RRP: £121.99

Category: Midbass & Midrange Speakers

Product code: TeamZXM8/4

Introducing the Team ZXM – Developed in our own facility here in the UK by our new engineering team. This is a clean sheet design which has been developed to offer elite level performance. Using carefully designed custom heavy duty cloth spiders tuned to each exact size we were able to develop for excellent reliability and performance while implementing measures to optimise the frequency response. The ultra-light weight copper coated coil allows for more sonic accuracy and high-end musical characteristics. We use a ground up built small piece Neodymium motor to optimise the cooling efficiency and motor strength while keeping the cost to a level where the units can realistically still be installed in quantity. Team ZXM also features a dual roll treated cloth surround a coated dimpled textured surface to the cone that acts to increase the effective piston area to move more air, creating more SPL while providing protection against the elements. We included dual oversize leads to provide an additional fail safe when pushing beyond the limits of the performance envelope in competition. These are great for small or large door builds in car, or they will delight in the studio in a 2 way mid top box with an appropriate tweeter and crossover. For keen enthusiasts looking for a lightweight and accurate sounding speaker the Team ZXM offers tremendous bandwidth, musicality and surprisingly good mid bass performance. It also has excellent detailed documentation making it easy to set up and use even in more advanced projects. We firmly believe that this is one of the best midrange / midbass speakers in its class.

Version History

Team ZXM concept was designed to offer an all-round Ultra high performance combine midrange/midbass device at a reasonable price point. The new engineering team drew up a wish list of specification points and made several prototypes before settling on the current basket, motor and cone layouts. From there detail changes were made to almost every aspect of the basic design focussing on each detail. Performance was optimised to allow the driver to run well in almost any application. The Team ZXM branding was originally conceived in mid-2019, with outline specifications in place by the end of that year. Prototypes were built throughout 2020 and first production models were made available Q3 2021
