Polk Audio C4 Monitor

I wanted one of these so bad when I was 18, (back in 1992) but at the time you could only find these boxes at very high end audio shops, and they were retailing for $500 ... The premise of design was intended for limited space vehicles like porsches and C4 Corvettes, and at the time I had a tiny little car so of course I wanted it. But back then I was poor....well now im still poor but at least there is ebay, where I purchased this mint condition one for $65 .... Its an odd enclosure alignment from Polk Audio, so I figure id share a peice of audio history with you all. I have installed this in my 1986 Corvette for the time being running off a little Kicker kx120 and it absolutely bangs for what it is.

For the fun of it I put it on my meter last night and it was doing like 139...lol //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Maybe with a real amp it would do better.

Just thought id share.

Very interesting, the Isobaric mounting is so rare these days.

Yep, I should of mentioned that, its four 6x9 subwoofers. Very oddly made box as well, took alot of time to build it the way they did. Im always searching for odd stuff to buy on ebay, and this definately qualified.

That is a nice piece of audio history! A friend and I built a push pull isobaric with two 8" Fosgates back in 1988 that absolutely pounded. It was loaded with the ports facing rearward in the back of a 1982 RX7. If the ports were facing forward it hardly made a sound, turn it around though and the bass reinforcement was amazing. Always blew peoples minds when they found out it was a pair of 8's running off a small Alpine amp.
