Wow! I love this sub. Very deep sound. Not boomy like similar products tried. I have it hooked to a Azur 540R Version 2 6.1 AV Receiver. I am using a 6 foot sub cable from Signal Cable [..]. The maple veneer is 1st class. It looks more like a piece of art than a speaker. Most subs are very very ugly & that weighed heavily on this purchase. For $399 & free shipping it was a steal! I recommend this sub.
