    • The real deal.
This is an excellent unit for my mobile wedding / pub gigs. There are products that go 'lower' or go 'louder' but this thing delivers excellent punchy bass that fills the room day-in and day-out at a great price. Combine it with a screw-in type crank-handle speaker pole and you have a solid base for even the biggest tops. Pairs great with my 68lb SRX812's. The included built-in casters are quiet and strong. Don't forget to order the factory cover to keep your investment safe! ... show more

    • You want this!
Had this for a week and a half now and love it sounds great and was shipped with care and discretion. Arrived ahead of time. Put it in my home and haven’t even run it very hard yet but being an 18” is it’s very impressive. I bet my neighbors hate me now!!!

The media could not be loaded. The camera mic doesn't do justice. Very powerful with tight robust bass. Matches perfectly to QSC k12.2's.

    • Issues with this sub
Loved the sound when it worked...casters would rattle, but that's an easy fix. This sub stopped working after being used 3 times. The first time I used it, there was an odd odor coming from the speaker. The next two times it worked fine, no odor. I always test my equipment prior to gigs, as I got ready for the 4th gig, this sub would power on, no sound. It's been in the shop since the last week of September with an amp module on order and no real date as to when it'll get fixed as everything is backordered. I do have another sub at home, but I regret selling my 181s now as I never had issues with those and had them for years. I never had trouble with any QSC equipment until now, so I'm not sure I'll be purchasing any additional QSC equipment in the near future and definitely won't buy this sub again until they have fixed the issues. ... show more
