Reviewing The Earth Shaking Bassboss SSP118-MK3 Subwoofer

This is the most incredible sounding, best build Subwoofer I have ever seen. It took a lot of saving to purchase my Bassboss setup of (2) DV12-MK3 AND (2) SSP118-MK3. But let me tell you that they are worth... Honestly cannot put into words the experience you get with this sub. It has such a worm, full, thumping sound, and no matter how low the music gets the sub never ever backs down. This single sub claims it has more output then most double 18" subwoofers at low frequencies and I believe it.
