syzygy

Went ot the local car audio installer. The impedance is right around 4 ohms for each sub. What can I use to at least try these out. I might also be interested in a trade for a HT sub if anyone wants dual klipsch 12" subs in their car.

Thanks for the replies. Is there some diagnostic tool or approach to figure out what is inside the box without dismantling it? And determine if it is set up for mid-bass etc. I haven't hooked them up yet and am a little leery of just hooking them up to my receiver. Guess I could see what happens when I use them with an old sony receiver.

I came across a pair of Klipsch RW-12d built into a ProBox Subwoofer box. Word is, these were built by a Klipsch employee for his personal use. At the price I paid for them, I could not pass them up but I am now wondering if I can use these in my home. The ProBox with subs weighs approx. 90 lbs so I believe that the amplifiers my be inside the boxes but can't be sure. The back of the box has two speaker wire connections. Can I use these at home? What is likely inside the box? Is there possible an ohm issue and if so how do I overcome that. Any thoughts on whether amps are inside the box or what type of amplification is recommended is aslo welcome. Thaks in advance for your replies. I'll try to add some pics soon of the box, its an pretty impressive unit. Update they are working fine with the Hafler with minimal noise, KSP-400 subs still on and powered by their amps. Still have two issues Using 80hz cutoff, 1) KSP-400 turned up 1/2 way and 1/2 bass boost I get "chuffing"? at very particular points, otherwise pretty good sound for music 2) Missing DEEP bas on orchestral music and movies. Any sugestions. Could the woofers in the 400 need rebuilt/ replaced/ upraded. how does on do this? thnkas

What is rceommended for replacement/upgrade wookers for ksp-400s. I am still dialing them in (any helpo welcome) but when playing music with some heavy bass I am getting a lot movement out of one of the woofers. They just seem a little worn and not as tiht at they should be. What can be done and where can I get the woofer(s)? Thanks in advance jeff
