Awesome Subs

I purchased a pair of these last summer from Nick at Sweetwater and let me say they are great. With my Yamaha DXR 15's on top, everyone raves about the sound. We usually use a pair of JBL PRX 518 subs, and added these for outside gigs and what a difference. These killed the JBL's hands down. Do yourself a favor and check these out.

DSR118W Subs

I would recommend these subs to anybody that wanted to have a killer sound. I've been playing music my whole life since I was 10 and I've never heard speakers sound this good. The lows are musically sweet to the ear. I Bought two and have them paired with 2 DSR112s and man I'm blown away with the sound thanks to Yamaha and a Special thanks to Sweetwater music y'all are awesome.

I just purchased 2 of these bad boys and let me tell you they ROAR. These are the cleanest most powerful subs I've ever owned or ever heard and I've heard a lot of them. I've got them matched with a pair of DSR112s and together its simply amazing the sound they reproduce. So i would recommend these to any body i know just make sure you get them from SWEETWATER they absolutely without a doubt have the best customer service and believe me I've dealt with them all. So get you some of these you won't reget it.

Nice Sub

Sub is as advertised, no issues with performance. I really like the line -X protectiion, it looks great and will not scratch like the DXR/DXS series. Spend the extra money, get the DSR.
