Thiel Owners

unsound

I have the equalizer between the preamp (Marantz 7T) and the amp (Marantz 15). I've tried the 20 and the 40 settings but haven't detected any difference. I have had the amp and preamp completely gone through and restored as needed. The amp, although rated at 70 watts into 4 ohms is actually putting out 80 watts. I know that may be on the low side but the room is not large - about 12X12X8. The bass doesn't really seem to be significantly different from the equalized 1.2's. Maybe my expectations were too high; I was hoping to be able to feel it (without too much volume)!  

Can you hear a difference with the eq in or out of the chain? With the eq should make a noticeable difference. Otherwise your eq may needs a check up. I have had 2 of mine repaired as they are vulnerable to static electricity.

I’m guessing you meant un-equalized CS 1.2’s?
Checking the eq is a good suggestion. I’ve never had a problem with mine, but in the last 30 years there have been some reports of eq issues. Your available power is just about the minimum suggested for the 3.5’s, but it is a small (and not ideally proportioned) room, and that might the reason for the limited bass response. I’ll hazard a guess and say the 40 Hz setting will probably work better in your room.

Happy Friday! All

Thanks for the suggestions. I know the eq has been recently recapped so I suspect it is operating properly. Although I’ve never really used an equalizer I do currently have one ( other than the Thiel one) in my system - see my virtual system under ‘Frankm1’s (mostly) vintage system’. I’ll try the 40 setting for a while and try some different source material.
