Comments about Gemini GVX-SUB12P Powered Subwoofer:

It came on time. I opened it up (Looks great), plugged it in, powered it up, and NO SOUND.

I plugged into the crossovers outputs and had sound. I had to decide if I should call Musicians friend or pull the back off. I pulled the back off and found the negative wire had never been soldered to the speaker.

I soldered the wire to the speaker, put the back on and BOOM! This thing sounds great. I use it with a Kustom Profile 200 Portable PA System and mixer and the Aux out for this sub and just love it. My Korg seems like a new instrument with the solid bottom (Not boomy) I get from this sub.

I'm glad I chose this one. QC needs some work (4 stars), but the sound quality and features for the price are great!

I just received the sub yesterday. It was definitely a good addition to my active speakers. I'm thinking about purchasing another for bigger gigs!

great value for a 12

By DenB

from NC

Comments about Gemini GVX-SUB12P Powered Subwoofer:

Very good overall value and output for a 12" sub - I play acoustic with a bass player and it picks up the low end fine for what I need. I keep everything cranked and use the mixer controls, but overall glad I bought it even though I don't really need it unless my bass man is with me. Also super cool to run my iPod through and hear the windows shake. Finish could be better, but I'm not that picky and don't sling it all over town. Looks good with my EV zx1 flying over it too.

Comments about Gemini GVX-SUB12P Powered Subwoofer:

This 12" sub for the price is hands down the best. nothing in this price range even compares. i did sound testing with many other brands and this sub blew everyone else's away. i'm very satisfied that i picked 2 of these bad boys up. they look good and sound even better.

Good Sound But Be Weary!!!

By Macman1962

from Saginaw, MI

Comments about Gemini GVX-SUB12P Powered Subwoofer:

Receieved two today, and both had something rattleing inside. I looked and found pieces of a capacitor that was broken. "On Both!!!" One of them still worked, the other was DOA. Very dissapointed because I really didn't want to get a bigger or heavier sub and they really look nice too! It's a shame.

Comments about Gemini GVX-SUB12P Powered Subwoofer:

Recieved mine in the mail earlier today and it had a clunking sound inside when it was picked up to be moved. I opened it up, and the wire coil inside was completely busted off fropm the rest of the unit, the wood is very cheap and the finish flakes off. It was beyond easy repair. Save your money for a better product. I don't recomend this as a budget buy.
