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!

Hey @vair68robert

Given the cap sizes you are talking about I'm assuming these are in low pass sections, and going to ground. The Solens, or their cheap brand, Axon, will be great choices, BUT, you must maintain the original ESR + R of that portion of the circuit or you may suffer unexpected impedance issues, which causes your amp to suffer, along with changing the crossover points.

Save the top-end caps for caps that are in series with the drivers.

Best,

E
Hello all, returning with an update on my 3.5 mids.  I received them back from Tom this week and was able to do an A/B test with the original mids, rebuilt by Rob, and the  Scanspeak 12W/8524G00 speaker, which has been floating around on the web as a suitable replacement for the original Scanspeak mids.  The replacements were in my 3.5's when I bought them, I was able to score the mids from a fellow Audiogon contributor and had Rob rebuild them.  Anyway, I wasn't expecting much of a difference, if all, simply because I don't consider my ear terribly critical. I replaced on of the mids, put my preamp on mono, and played some ZZ Top (I am originally from Texas, so....) and did a close up comparison as well as sitting position in my listening room.  I was surprised at the difference!  The original Scanspeak obviously worked better with the crossover, the difference being that the rebuilt original was much clearer and articulate, where the replacement was subdued sounding. So what I thought was an excellent listening experience before the replacement has turned into an exceptional one. I kid you not. So I would say this  particular Scanspeak ( Scanspeak 12W/8524G00) is not a good match for the original. I think Rob is recommending another one, and Tom may have something to say soon as well.  
Amplifier update, my last post was lamenting on the binding posts on my Yamaha M85 and Denon POA 1500.  I replaced the posts on the Denon to 5 way, and sold the Yamaha and bought a Denon POA 2200, which I now need to replace its binding posts as it used the exact same one as the Yamaha.  My only comment on replacing the bindings is I was scratching my head on what to use to replace the strip of metal between the old posts and the PCB.  Then I remembered I had some romex wire from my basement finish work, so I stripped sections of the solid copper wire and used it.  Worked perfectly.  
Rob and Erik - The 400uF electrolytic is in series feed to the midrange. Bummer.

Doh, then consider the Mundorf electrolytics:

or Axon film:

In either case, measure ESR of the original and be aware that reducing it significantly can result in more midrange output. :)

Oh, wow! Welp, on the plus side there is more room for sonic improvement. But 400 uF of film caps will certainly need a new layout/board. And it looks like one of the other ELs is 220 uF. And not only much bigger but also $$$.

My new boards were much larger. I compensated in the passive radiator chamber by removing a similar volume of the fiberglass batt. But I only had two 100 uF ELs to replace. 400+ is probably still doable but complicates the issue and makes the upgrade spendy. Clarity CSA 250V is available in 100 uF for $68 each. PulseX 250V is more affordable and should be sonically superior to ELs. Lean on Tom’s Knowledge, Robert!
