Thiel Owners

Hey guys. I’ve been struggling with getting decent lower mids and mid bass with my 2.4s. It always seems tilted towards the highs, as if the bass control was set to -6 dbs. They are in a 16 x 21 room on the long wall about 3’ off the front wall to the back of the speakers. The pertinent gear is below, source doesn’t sway the general tilt of the sound, nor does the quality of the recording, but it can make it worse.

Equipment:

Thiel CS2.4’s
PAD Venustas rev. Speaker cable
Parasound A21 amp
BAT VK3ix Preamp (I’ve rolled many tubes) also has Six-Pack upgrade
Cardas Clear light interconnects XLR
REL 328 sub (for the lower bass)
Technics 1200GR Turntable
Glanz MFG 61 cart
Audio Research PH3se phono preamp
PAD Venustas phono cable

not sure how to get the bass to be more balanced with highs

it might be I’m in a bit of a bass suck out where I sit, but that doesn’t really explain the mid range not being as pronounced as it should.

Thoughts?

Lemming - what's your ceiling height?Are all drivers working? Finger on the cone test.You can check driver polarity with a 6 volt lantern battery. Best test is battery plus to wire at the disconnected cable at the power amp. All drivers should move out into the room.  

that's amp end of the disconnected RED wire.

My ceiling is 10’ high. 
All speakers are working. As for the battery test I’m a little unclear as to your directions

i could reverse one speaker connections to see if the bass improves, but assuming for the moment the highs are wired correctly and the bass was wired backwards my highs will end up out of phase, correct?

i would need to flip the bass driver wiring I suppose. 

Nice room dimensions.
Don't switch anything until you know if there is a polarity problem.Disconnect the cables at the power amp. Connect 6V battery - minus to black wire and touch + plus to red wire. The coax and woofer should both move out. Repeat on other speaker.

Your symptoms could be created by 1 woofer being polarity reversed.
