Building Watt/puppy clone

Paul, yes. I thought I already covered this above. My Maggies and a test CD say I can hear a 20 kHz signwave, referenced to a 1 kHz sinewave at about 79 dB on a radio shack SPL meter, in the listening seat. Of course, the 1 kHz tone sounds pretty loud at 79 dB, and the 20 kHz tone sounds several dB quieter, but I can still hear it easily, along with the accompanying intermodulation waveforms that must accompany such a waveform, in the redbook format. The 20 kHz tone sounds much "dirtier" than even the 19 kHz tone, though. The 18 and below ones sound very clean on my CD50.

If you really want to build a nice DIY speaker look at the Focal TLR Towers. The TLR tweeter is much less harsh than the other Focal tweeters, but cost about $450 each. I built a pair of the towers and love them. Good luck! www.zalytron.com

The guy at Zalytron has an attitude problem. I like the best soft dome tweeters, like the Revelator and Esotar.

LOL Carl! Your right, Elliot has a very big attitude. I have had many successes working with him though. His 1 1/2" think MDF cabinets are beautify. As far as tweeters my personal prefference is still the TLR over the Revelator and Esotar. (Yes I have actually listened to them) Another favorite DIY place of mine is Michael Percy Audio. http://www.bainbridge.net/percyaudio/ Great caps, inductors, etc...

I like the large gauge North Creek inductors very much. Michael Percy needs his own website. I can buy all the MDF I like, it's cheap...the problem is building these things. Takes a lot of time, but it'll be worth it. I hope to get someone to manufacture a couple of these some day.
