Defective right out of the box. In my eyes this means poor quality control. When I plugged the subwoofer in got a loud humming or buzzing noise even with the switch in the off position. I would buy another product from this company.

Powerful, sounds great, not a bad purchase. Would recommend!

This sub is awesome. It delivers excellent sound and power, and has been a perfect addition to my Ai60s. Setup was very easy as well. I’m very happy with it.

Great quality, perfect sound on the 12" subwoofer!!

This is a awesome power subwoofer..it is worth the money and more...if u looking for a power subwoofer get this one!!!

I am absolutely ecstatic with the performance of the signature series speakers.Definitely the cleanest purest sound I’ve ever had in the stereo. And your turntable is absolutely amazing.

Low power. Contacted manufacturer to replace what sounded like a blown sub right off the bat. They sent me one but their last email says it's still waiting to be sent. They don't know what's going on in their own office. I bought 2, both are underpowered and disappointing in bass reproduction. Probably going to replace the subs with better and the amps myself.. keeping only the cabinets.

This subwoofer is great with lower end sound, it struggles a bit with more punchy sound but the speakers compliment it well. The only reason I gave it 4 stars was that when the subwoofer is really working hard the air ports produce a wooshing sound.

This sub is definitely worth every penny, beautifully designed and the price is definitely worth it. This thing kicks out some serious bass, have it connected to my AI60 powered bookshelf and all I can say is I definitely made the right choice.

Full sound, good value!

Very susceptible to feedback. You h to finely mesh the amplifier volume with pre-amp to achieve full volume with little to low fuss. Upgrading the tubes to 12xa7s helped I bit as well. Also worked on isolating the preabmp and turntable from other as well as any other components. The complements look great, are of (high quality) it appears so far. Yes it seems like a lot of money, but upgrading in this business is not cheap.

We purchased the entire Signature Series and the Sub. The Denon 4400 AVR has auto tune and is a really good match for these speakers.

It looks nice and has amazing sounds. Highly recommend this sub

Very happy with my purchase. Delivery was very quick and if anything the packaging was over done. Appears well made and the sound quality is quite impressive.

Nice quality and appearance. However, not very efficient. I paired it with a 12 inch Acoustech sub on each side of the couch. The Fluance is significantly quieter than the Acoustech.
