extremely good value for your money! I hooked it up to a vintage receiver. as there are no sub RCA outs on these things. you hook it up to your tape out line. and control the volume on the back of the sub. I. gong to experiment and hook it up the other way. with speaker wires. then use the speaker wire outputs to run to my other speakers. that way the sub volume will rise and fall with them once I set the master volume on the sub with the other 2.speakers. this is WELL worth your money. it just thumps and wakes bookshelf speakers up when tuned right. .

A GOOD VALUE FOR THE PRICE

Was a bit heavier than I'd have expected. But it's very rugged and well built using quality components and produced the deep bass that I wanted. A good value for the price.

Have always used 12" subs. Going from that to an 8", i was initially skeptical. I'm using this sub in a small work shop and can't believe the chest pounding sound it creates! 100% sarisfied with the performance.
