Thiel Owners


Guys-

I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!

Tom - thank you for mentioning the reference tracks you are using as well !!!! Music is after all the point !!!!
tomthiel,

Thanks for the interesting update. As an owner of a pair of 2.2s, I think this model represents a great place to start on the upgrade path.

The use of an external xo makes a lot of sense, both for practical and sonic reasons. My 2.2s are on a carpeted wood floor with an unfinished basement space below them. I could easily run an umbilical cord through the floor and place a xo box in the basement underneath each speaker. That would be very cool!

When you can, please continue to post upgrade updates for the xo, the cabinet bracing, and the vibration management efforts.

Keep up the impressive work!!!

One interesting aspect of external crossovers, is that so many aspects in the cabinet are devoted to vibration management. Gluing the parts to the board impinges on thermal stability, but if left unglued, they rattle and buzz and introduce microphonics. Out of the box, that aspect is not a problem. Also, a major limit to directionality of coils is their position in the driver magnetic fields. That goes away too. And the heat thing is big; the enclosure keeps getting hotter, whereas the EXO self-cools. And two-sided boards become practical for isolation of resistors from caps. You get the picture.

SDL - I love the basement idea. But also, these EXOs will be in presentable cabinets of their own. I can’t help it, I was born that way.
Tomic - I have reverted to point to point on masonite - no printed circuits. When rebuilding Beetle’s 2.4s (late / Chinese, on PCBs) we noted coils with up to (perhaps) 20% variation from spec. Those changes were required to re-balance considering the capacitive coupling to the PCB traces. I prefer to keep the coupled capacitance separate from the inductance. I am also at greater liberty to manage the layout to avoid parallel leads and/or bring them to contact and twist to virtually eliminate self-capacitance.
I am loving the audition material selection. By randomizing it via the next album alphabetically, I have reduced the tendency to design for only the best audiophile material. I learn as much from ordinary or substandard cuts as I do from great cuts. However, anyone is welcome to send the Chesky catalog or other great stuff.
Eric - you are most welcome to share your turbulent / laminar flow ideas if you wish, either here or via PM. I have a setup that works, but might be significantly improved. I cover the baffle with F11 pure wool felt at 1/8 or 1/4", covered with the finest Ultrasuede Fine fabric. The drivers and bezels are covered with a stretchy version of USF. The US surface fibers are so fine as to be moved by the pressure - shear waves. The effect is lovely. I am now working with an aerospace engineer with a technology patent for surface flow dynamics management for spacecraft re-entry.
No end to the fun.

Long Island,  will be open for business very soon. Health conditions are improving on  weekly basis. Not certain about the other 4 boroughs?

Happy Listening!

@tomthiel 
Um, was this for me, or is there another Eric in this thread?  I don't remember saying anything remotely related to fluid dynamics. :)

Best,
