*UPDATE* - I've been using my TS112A for months now and really liked it (notice the past tense).
I recently was asked to play bass in a band and have been using my HD500x for bass (loving this) and, through the TS112A, I've been getting rave reviews on my tone.
However, I played my first OUTDOOR gig this thursday past and, while the unit held up well, I powered it up today and find that I have what sounds like a fried voice coil! YUK!
Currently on hold for customer support to see what they can do...we'll see!
Well, after only a 20 minute hold, I got Rich on the phone and he was ridiculously helpful! I simply told him of my troubleshooting and he said, "yup, sounds like a voice coil". He took my info, I emailed him my amazon receipt, and sent me an RMA for return (I have to pay the shipping though). Customer service seems pretty decent.
If my shipping is cheaper than a new 400W 12" driver, I'll send it back for repairs. Otherwise, I'll just drop something else in there. Unfortunately they are 4 ohm speakers...anyone have a good source for 12" drivers??? I might have to go from the car audio realm since most PA speakers seem to be 8 ohm in my experience.
