Thiel Owners

Hi Tom,

Thanks for the info.  I was actually very surprised to find that large a value for the cap at 400uF+.  Is it because the intrinsic impedance of the driver is somewhat low?  Or is more has to do with the time-phase aligned nature of the xover?

Thanks.

Andy -  the circuits control the drivers for a net 6dB / octave slope all the way down, including the interaction with the top end of the port where another pole is added to the top end of the woofer xo. Various conjugate circuits are applied to counteract bare driver anomalies. Since the usable driver range extends more than 3 octaves beyond the crosspoint, drastic measures can be called for.

As I said, I doubt that Jim would have tried to cross that midrange with that woofer, requring so much attenuation. He would have developed a smaller midrange with a higher natural bass roll out, to better match the 8" woofer with less brute force required.

Thank You for citing your system- especially the cables! 
Keep us posted as you massage those Thiel speakers into your room/system.  Bryston is a sonic match.

Happy Listening!

Some Bryston’s are compatible with some Thiel’s.

hi Bighempin,   it was great seeing you and i am so glad you enjoyed your visit.   I am honored and pleased that my system sounded so good to you.   I  am such a huge fan of the PS gear and think the BHK amps are fantastic with Thiel speakers (at least with the 2.7and 3.7 as i have not tried others with the PS amp).  However i think that most people who have not experienced what one of the PS power plants can do are missing out on getting the best from their systems.   I have owned numerous iterations of them and the P15 and P20 will transform your system for sure.  Even the older and smaller models are great and are critical for a system to perform at its best.  I sure hope you can get the speakers you want especially the 3.7's as they are like mini IRS speakers.
