@dfp - If the woofer surrounds are rotted, contact Bill at Millersound, for expert service.  Look them over, before cranking them up.  Bad surrounds can result in trashed voice-coils, and a higher-Dollar repair.   http://www.millersound.net/speake... 
What can anyone say about Quarter Wavelength transmission line enclosure design ?
These ARE, by definition, "transmission lines" and have been found wonderful designs for bass reproduction, by the experienced and dedicated. http://diyaudioprojects.com/Technical/Papers/Non-resonant-Loudspeaker-Enclosure-Design.pdf Good stuff, re...

@millercarbon- Affirmative. Built three pair of those. Excellent, extended, authoritative, articulate and tuneful bass. The system did a good job of extending the dynamic range of the electrostatics too, relieving them of the longer excursions, de...

Fried, and his IMF(Irving M Fried) designs, got me interested in TLs.  Man; that's been awhile(I'm dating myself).

I built a pair (in 1981), per Roger’s design, to go with a customer’s Acoustat Model IIIs. He wanted something that could match the speed and definition, of his electrostatics. They worked so well, powered by a Halfer DH-500 and crossed over via a...

That, Glass Audio and Audio Amateur, were my favorite rags(back in the day).   Inspiring!

Best Tonearm Lifter?
btw: I found placing a tiny O-ring, on the AT6006’s cylinder, to save my correct height, went a long way to simplify the adjustments. Holding it both vertically and horizontally, exactly where I wanted, while tightening the screw, was just too big... 
Best Tonearm Lifter?
I bought my first Audio-Technica Safety Raiser(AT-6006 ) in 1980, for $19.98. It worked flawlessly, for over 30 years. Then, something apparently dried out and it began lifting more abruptly. I found two NOS/NIB pieces, on eBay, and bought both. W...

@millercarbon- Did you happen to find that design in the Speaker Builder Magazine articles(circa- early 1980’s), written by Roger Sanders? In them, he outlined building a 10", TL woofer system, closely matching your description, to compliment his(...

@erik_squires - Experimentation(a lot), back in the early Eighties and DSP, now. Wasn’t all that hard!

Of course, those are being actively bi-amped.  Only producing between 80 and 20Hz(60dB/Oct cutoff).    
Do you ever do this before you listen?
Especially after a skydive(well...from.anything over 13.5K).

Too bad you can't hear my pair, regardless of what I type(8', tapered, folded, w/10" Seas L26RO4Y D1004) .   Are you ever around the Indianapolis, IN area?
