Default Decent Cheap 6.5 " FR drivers.

I bought a pair of these off ebay for 20 dollars shipped (I bid $9.95 and got them). They are QUITE good! I put them in my Polk RT600's. I started by running them full range (no crossover). They have great, smooth bass, a very smooth midrange, and highs usable up to 12 kHz or so. I found the extreme highs a bit missing, so I took the Polk's existing tweeters and crossed them over with a 1 uf film capacitor in series with an 8 ohm non-inductive resistor (to lower the tweeter's output and drop the 3 db point of the crossover to 10kHz).

I'm running them with a Sonic Impact T amp with its input caps replaced. These speakers sound AMAZING! They image SO well!
The stereo image is wide and deep, MUCH deeper then any other Polks I've heard! They play reasonably loud too.

The supplier must have a decent amount of these, as he puts a pair on auction every week.

It would be really cool is someone bought a pair and ran some measurements on them-I'll bet they measure quite well! The Qts
must be low-because they work well in the Polk's ported/transmission line cabinets.

Here's a link to this week's auction-like I said he sells a pair about every week, so he must have a bunch of them. They arrived sealed in their original OEM packaging.

My only complaint is that they sound so accurate that they show up all the bad audio on TV-especially the mikes on live newscasts....

Sorry about the late response. They look to be similar to the 5" drivers I've scored ex Panasonic 48" rear-pro teles. I haven't listened to them yet. They did have small cone tweeters.

I'll remove domes and add a plug, and treat the cone.

Geoff.
