Pyramid/Sequerra T-1 Tweeter

The current model (Sequerra T-1 Mk IV) retail for $4500/pair on the Sequerra web site. Mine were manufactured by the Pyramid Loudspeaker Corp which I assume is out of business since I can't find any reference to them on audio sites. I haven't listened to a lot of ribbons and can't give an opinion on relative prices. These sould fabulous. I have Scanspeak tweeters on my speakers (Nova Audio Rendition) and the Pyramids edge them out for clarity.

Thanks for all the responses. Let's sort of answer things in order. The Nova Audio Renditions are fine speakers. In fact, they're spectacular speakers. You can listen to them if you live in the Washington DC area but I'm not quite ready to start a loan program. My HT system is pretty much finished so now I'm playing with toys. I bought the Sequerras (and I did get a pair) to compare with my Scanspeak tweeters. They're clearly not the MK IV. There's no date on the speakers or literature, but the speakers say "Patent Pending" so they're the first model of whatever they are. They are about 5 inches high, 4 to five inches wide and about 8 inches deep. They do look like a truncated pyramid. They have honking large magnets. If I put them within 6 inches of each other they immediately slide together. I sent an email to www.sequerra.com asking for more information but that was on Friday night and I'm sure they won't answer before Tuesday. Well, got to go. I bought some new CDs today and it's time to crank up the volume.
