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!

@thielrules, Thank you! What kind of expense would one meet to retrofit the co-axial's to the 3.5's?

My pleasure to assist you. Thank You for citing your musical tastes and Rob Gillum's help from CSS.  There are quite a few DIY guys here that are making real progress on finding modern cross-over/driver solutions for their beloved vintage loudspeakers. Take your time persuing this thread, you will find a plethora of information on Thiel Audio 3.5 model.
Happy Listening!
Unsound, the chamber volume for the coax requires almost a doubling of the space that the 3.5 offers for the mid-range driver (using space measurement of the cavity of the 2.7 compared to 3.5). Most practical way would be an expansion of the chamber on the back of the speaker, using a cardboard tube and wood. The front bevel opening would need to be enlarged with an extra inch or so, for which there is enough room. The new coax drivers are about $550 each, not sure about shipping costs. Depending whether you have the tools and skills to do the woodwork, you can estimate your "investment".
Wow the level of expertise of Thiel DIY'ers is amazing .

Thank you @stspur for your impression of Mills resistors with them being your first upgrade .  
They are next on my list .

A correction about the wire used in the Tennessee CS2.7 ,
after replacing the wiring with Cardas 15.5 AWG 
I looked at the original wire using a 30X magnifying glass
and can now see the missing dot making a 16 and not an 18 AWG .

A lot of work replacing all the wiring , 
BUT I'd have to say it's worth it given the improvement I'm hearing .
Jimi Hendrix  "And the Gods Made Love"
never swirled with such detail before .
One more thing ,
I replaced the fiberglass batting with wool quilting batting .

Just picked up a pair of 3.5s 2 days ago. Paid $275, but the cabinets are pretty beat up… delaminated veneer, minor moisture damage, scratches & broken grill frames. Also, pushed in tweeter domes & a small dent in one mid-range frame. Nevertheless, the drivers reportedly all work and sound great. We shall see.  

 

For me… this is the perfect purchase.  Beautifully engineered audiophile speakers, highly successful design, years of development by experts with audio skills that far exceed mine.  A great platform to work with.  Woodworking is no problem; but, I’ve got several projects I’m still working so this one will have to wait a bit.  Just starting research on these speakers and what may be my best approach.  IF I were jumping in right now with the limited research done.  I would look at:

ESOTAR T330D tweeters (a favorite of mine)

Scanspeak Illuminator 12MU/8731T-00, 4.5” Midrange

Vifa M25WO-35 6 ohm 10" original Woofer

Shelve the Bass Equalizer & add a 10” or 12” powered subwoofer to each speaker.  I like to build powered sealed downfire SWs into the bottom of the speaker. 

The Illuminator mid-range is interesting as it solves some of the problems experienced with the original.  SPLs a little higher, but it’s able to go lower (300Hz Xover no problem) and has 150W long term max power rating compared to around 50W with the original & 30W with the 10F.  It would take a lot to burn up the voice coils on these.  Appears to also be a little easier load on the amplifier and it reportedly sounds very good. But Oh-boy is it expensive & will require a bit more breathing room in the cabinet.
