Description

DS18 SRW8.4It's easy to get great bass when there's very little room with our new line of slim mount subwoofers. The SRW 8.4D (DVC) and SRW 8.4 (SVC) mounts in little as 2.83 inches mounting depth and can be utilized in both ported and sealed boxes for great bass in a tight area. This sub handles 150 watts RMS and 300 watts peak power with a 88 db sensitivity which is very high for a slim mount sub raising this model high above the bar. This sub comes in both dual voice coil 4 ohm (SRW 8.4D) and single voice coil 4 ohm (SRW 8.4) so you can wire appropriately to your amp for maximum power to bring all your music to life!

  • Great subwoofer!
I LOVE this subwoofer! Excellent replacement for the 6" sub in the new Gen6 Bronco 7-speaker system. Excellent addition if you're adding a subwoofer to the 2022/23 7-speaker Bronco that didn't actually get a functional subwoofer. I put this in the 10-speaker sub housing I bought off eBay. About 5 minutes of trimming and attaching the new subwoofer and I was good to go! Works great on the OEM 7-speaker amp or a Musway 5P. ... show more

  • Perfect for 06 mustang lower doors
Got these to replace the factory lower door subs on an 06 Mustang (with the shaker system) connected to a dedicated 2 channel amp (150x2 @4ohm) and they bump great for inside a door. Also got the DS18 speaker covers which match perfectly. Using the low pass filter and they’re nice and clean.

  • Powerful for the size
I purchased 2 of the 8inch ds18’s for my BMW 335i to replace the under seat speakers. I had already wired up and amp to be able to handle the subwoofers. After install the speakers blew my mind and have held up really good. Would definitely recommend and more and likely will purchase one for the trunk if I need more bass but these have me more that satisfied…💪🏽 ... show more
