The PR2 uses his own woofer, and tweeter with an XO at 1200 Hz (not many 1" domes that can go that low)

Default dave, thanks for the info!

The only ones I had seen were the bookshelf types. I think Perkins has been overlooked and deserves a little more recognition and respect (overall)

I just about bought a pair, but backed out because the driver had a tear in it and I was unsure of a repalcement

I second the Spica TC50's. Most people never heard them at their best. We used to put them on Rowland Model 7's in the store I used to work at. Basis TT, Graham arm, benz ruby cartridge, rowland consummate preamp, all cardas golden. Wow.

I sold quite a few of those. A standout.

A couple of 80's British budget classics, the Wharfedale Diamond, (only the Mk1, they went rapidly downhill with later versions), and the Tannoy Mercury, a great little floorstander that was my first experience of real hifi.

The Minimus 7 was subject of an article in several issues of Speaker Builder -- and they regularly went on sale at Radio Shack. Here's one suggested crossover modification from 1988 (another in 1991 put a Zobel on the woofer. One of the problems with the Minimus was that they were hardly "standardized" so mods had to be modded.

This may be a repeat but, my first experience in "Real HiFi' was Bozak, The Urban. They were huge, infinite baffles!

Ampex tape machine into McIntosh amp. I was hooked forever!

That 1st one won't work very well. The inductor shunting the tweeter will roll the T off, but the 4.7 in series with the woofer is going to act as a HP at ~5k making the woofer largely redundant. Are you sure the cap shouldn't be on the tweeter leg?
