It's easy to get great bass when there's very little room with our new line of shallow mount subwoofers. The SRW8.4D (DVC) and SRW8.4 (SVC) mounts in little as 2.95 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 86 dB sensitivity which is very high for a shallow mount sub raising this model high above the bar. This sub comes in both dual voice coil 4 ohms (SRW8.4D) and single voice coil 4 ohms (SRW8.4) so you can wire appropriately to your amp for maximum power to bring all your music to life!
