Curb find.....

503Timber · 2nd June 2011, 11:44 PM

Driving to pick up my daughter from school today I came across a free pair of Infinty RS 4B's The woofers need foam and I'm doing that now....can't wait to see what these can do.

What a great score!

Do the RS-4s have the EMIT?

Peace,

Dave

Thanks guys They do have the "Samarium Cobalt Emit" and the "Polydome rapid-acceleration mid" One of the woofers is blown so I am on the hunt for a replacement but all else seems good. One question for any Infinity lovers out there.......how the heck are these woofers wired? My guess is series but all wires were disconnected when I opened them up so I need to solve this wire riddle. The reason I think series is there is a "jumper" wire......short wire from one sub to the other.

Yep....that's them dave

Thanks Planet10, they are the ones I was thinking of. I passed up a chance to buy a pair a couple years ago. They might be the first "high end" speaker I heard. Late '85/early '86, local shop had a pair hooked up to a full HK system with the 825 pre and 870 power. Had a CD of different sound effects. The jet plane sounded like it was flying over your head. I've never been able to break away from audio since!

Peace,

Dave

Hey 503Timber, check out Infinitiy's website. Even though they no longer carry parts, from what I remember Harman International is pretty good about having documentation available in PDF. I got the schematics for the Qa, Qb and Qe from the site, and they are even older than your RS-4B's.

Ok, I just looked at Infinity's website, they don't have the docs for that speaker listed, so you may have to email them. But for good news, they did have the woofer listed as available. $43 and change a piece.

Peace,

Dave

Dave.....thank you so much for the detective work. I must sheepishly admit going to Infinity never crossed my mind.....maybe it's been a longer week than I thought. I'm going to check it out now and place an order.

Turns out the numbers on my woofer are different so I emailed to find out if it in fact will work. I also asked about a wiring diagram.....these things are a rats nest!
