Sound Splinter Supreme Series

Welcome to the newest addition to SoundSplinter's family of high fidelity subwoofers. We are proud to introduce the first production driver ever to use TC Sounds' patented Linear Motor Technology, to the open marketplace with our RL-s Supreme Series. Truly one of the most powerful and uncompromising distortion-free subwoofers available on the market, this is not a practical driver for small-scale applications. For those with the inclination, along with the space and necessary power feed on tap, the RL-s LMT will be sure to create an aurally supreme experience nobody listening will soon forget. All Supreme Series drivers are produced in single 4 voice coil configuration and optimized for moderate to large sealed enclsoures with input power levels between 900 and 2000 watts (1000 watt RMS).

- Single 4 ohm voice coil
- Gold Plated Terminals
- Copper shorting ring
- Woven Lead Wires
- Aluminum Cone / Heat Sink
- Powder-coated high excursion basket
- Tall, rubber Surround
- Thick Gap Plates

As one of the lowest distortion subwoofers in existence today, while boasting an extremely high excursion capability of 3" peak-to-peak, anyone demanding the richness of true-to-life sonic accuracy has finally met their match. Featuring a custom-wound linear voiecoil, this product will maintain constant force (BL) throughout its entire stroke. Coupled with a high quality copper shorting ring to reduce flux modulation, these drivers will claim some of the absolute lowest distortion figures of any subwoofer around.

SoundSplinter is fortunate to have a partnership with TCSounds Incorporated, one of the leading subwoofer OEMs (original equipment manufacturers) in the world. All of their technology is designed and produced in the USA by experienced mechanical engineers who have worked in the speaker industry for decades.

Warranty: 1 year.
