Thiel Owners

^i’m happy that you found the source of the problem so quickly. Perhaps sending both drivers to Rob so that they can be properly calibrated and matched might be prudent.

I have decided I’m getting a luxman l-510x to be the pre amp for the krell fpb-300. One step closer...

@thoft Is that an intergated amp? Does it only have RCA outputs?

In a previous post, I described the 2008 COAX terminal connection backwards (not important).

I just got off 2 email threads. 

1) The Audio Engineer in Canada, Mitch Barnett, looked at the new graph I sent him and said we know for sure it is now the COAX drivers that have a problem. 

2) John Siau from Benchmark looked over the specs of the Thiel CS3.7 and said the amp will work in mono. That is the mono amp will not damage the speaker. I should take the 30 day home trial and see if it actually improves the sound.

3) I will get in touch with Rob and pick his mind on what could be the cause of the COAX issue.

Yea it is integrated and only has rca. I’m not too concerned about xlr connections. It’s a beefy unit. I’m getting it to replace the luxman l-450 that i was using as a pre amp even though it’s not meant to be used as one (doesn’t have pre out)
