Surprised these haven't sold! I wanted a pair of these really bad at one time. Just found a new pair of TM65mkIII's and TM25's on Facebook being delivered today. Have AF GB25's I'll use in lieu of the M3's. GLWS

I have heard great things about the driver. Just never got around to utilizing it.

I’m selling to buy baby gear. My wife is expecting this June.

Enjoy those GB25’s. My current 3 way is:

*ScanSpeak Beryllium Illuminator D3004/6040

*Audiofrog GB25

*Stereo Integrity TM65mk3

Plenty!

When crossed as low as 60hz, it’s actually my extensive door deadening that begins to fail to keep up vs the speaker itself.

Be sure to REINFORCE YOUR DOOR/DOORCARD (and apply butyl rope) or the lil punchy beasts will localize due to mid-bass resonance from the amount of output.

I just bought a set of MKiii for 150. I paid under $400 for my first new set and custom made M3's. So 550 might be over market value.

The 3 way set last sold from SI for $587. So there's that.

TM65mk3 = $230
M3 midrange = $175
M2 Tweeter = $180

Total = $585 (those are at the lower presale prices).

Then add or subtract any value based on your viewpoint since these are no longer in production.
