Offering several models from 10″ to 15″ & even the new slimline RIOT FL10 got you covered in any aspect. Whether it be, efficient sound quality or spl, the master of many; The RIOT series follows the same engineering and are built with the same philosophy; More for less. Nothing is spared, vented poles, check, drilled engraved backplates, check, nomex spiders matched with dual wound 3″ voice coils, check. All such features are usually considered higher end and are charged for as such. The RIOT subs gives you premium performance and appearance all day.
The new motor now has a ventilated pole which features XD flow, (X-Drilled) which cools the voice coils from the inside of the bobbin which will increase the power handling. A total proven power increase of 25% (now 750 watts) compared to earlier models, they are now catering to both bassheads with the urge to demo for long periods of time, but also to the audiophile purists that need premium components in their systems.
