KLH Model Twenty Three imaging

While doing some TT switching around (sending out my idler for a retread), I decided to swap out my speakers. I have been listening to my Advents for several months. I like 'em a lot. But, My KLH Model Twenty Threes haven't been used for about 4 months. So, I hooked them up and was almost spellbound. They are in the exact same location/orientation as the Advents. But, they image sooooo much better. It's like the musicians are performing right in front of me. The depth is truly amazing! I had forgotten how nice they are. My son has a pair of the KLH Model Six and they sound quite similar. But, I kind of like the Twenty Threes a little better. The only issue is the occasional woofer "pop" that seems to be common to the old KLH speakers at volume. Sitting for long periods seems to make this a little worse. They improve greatly the more they are played, though. Anyone else noticed the nice imaging of the KLH Model Twenty Three?

Yep! I had a set I restored and they were terrific. My Six’s I still have and their dimensionality is amazing, same with the Fives.
Regarding woofer pop, back off on the bass setting a bit if playing loud. That pop is the vc bottoming out, not good. I’m surprised this is happening as the Twenty Three and Five share the same woofer. Have the surrounds been resealed? If not, you must do this. It helps tremendously with solid deep bass. If the surrounds are original, the sealer has dried out, and air passes through the surround cloth weave allowing the woofer to over travel causing the pop.

They have really nice bass. But, probably would benefit from a re-seal. I am needing to order some sealant anyways since I am putting a pair of Model Seventeens back together after replacing the capacitors. The last pair that I re-sealed was like day and night after re-sealing the woofers. I was wondering if my SX1250 could be a little too much power for them? I do run the tone controls "Flat" on all of my equipment.
