The Dynaudio tweeter was a D28/2 - 6 ohm. Rob has been looking, and is continuing to look for a drop-in replacement. Keep us posted on what you find.

Sandy - Here's a recap of model strengths and upgrade strategy. I hope those interested find value and that others can allow an old man his remembrances. The model 3 was our first best guess of addressing the most things required of a loudspeaker....

Sandy - I'm having fun sharing this stuff with you all. You're on it - most speakers scramble time / phase, sometimes by many hundreds of degrees. The ear-brain does a commendable job of reconstructing those wave-forms into intelligible music or s...

I'd like to share my thoughts regarding spikes; I performed the investigations way-back which led to our incorporation of spikes in the CS3 in 1983. As Sandy said, the chief problem is recoil. The effects, however, depend greatly on the floor syst...

The radial wavy plate midrange of the x.7 presents a better launch-pad for the center-mounted tweeter than does the previous midrange cones. The cone double diaphragm allows a much shallower front profile than standard, and is therefore more benig...

Sandy - I hope that name is OK, since that's your hi-fi identity to me. I credit Harry Pearson with creating high end out of its hi fidelity foundation. Hi Fi had been generally academic, formal and engineering driven. Hi End was generally young, ...

Correction: the CS3 was introduced at the Chicago Summer CES in June 1983, which is part of the 03b story.

Sandy - thank you for your remembrances. The 03a was the real beginning of it all. It upgraded the 03, which was Thiel's shortest run in history: one year. The 03 was our first product to address time / phase with first order slopes. We struggled ...

JA - one dovetail of the XO project with my musical instrument work is that I use the same listening, mic, software and equipment setup for both purposes. So, I am taking measurements while making the guitar, and making archival recordings for lat...

Hello Sandy - good to see you here. This forum is my sole on-line activity. My experience tracks yours. In all the years of demonstrating and exhibiting 3.5s, we (Thiel Audio) NEVER blew a driver, even when purposely tempting fate with high levels...

JA - the disciplines are related and knowledge usually cross pollinates. But my goals in Denver relate to acoustic guitar and piano design. Making the music is my heart's delight.

Hi guys - just back from the soundboard voicing masterclass in Denver. Physics rules the technical arts. I'd like to affirm these recent comments about the 3.5 and the progress of Thiel's models in general. As this inner circle understands, the go...

Rules - zero phase rings before and after a transient event. Minimum phase does NOT ring. It's worth some study

On a personal note, I will be traveling and out of contact for a week. I am attending a master class in soundboard tuning from the Australian physicist Trevor Gore. My primary occupation is designing stringed instruments and Gore's pre-retirement ...

Rosami - no firm news. The bankruptcy is still pending, so I am behind a curtain. I can say that I am enlisting talent to augment my limited abilities. I can answer your question regarding hot rod kits. Some general recommendations will flow (and ...
