SET vs OTL
Marty I thought your post was funny. 
SET vs OTL
Bill I have much experience with SET and audio design. Transformers mater as much as tube type not all 300b have weak bass rolled off hi. And as far as 45 50 SET as you say the best. Best for what? at 1.5 watts what can you drive? You need a louds... 
What matters most in speaker design?
The design maters most. 
SET vs OTL
Never said they dont have a slightly dif sound old Bill but I do disagree that 45 50 SET are the best all have there use and most can be used in hi-performance amp design. Maybe you need to relax a bit. Take some time off enjoy the weather and not... 
SET vs OTL
We all have personal tastes. Bill likes 45-50 as do I but I still stand by my post and Bill still using the mastersound you sold me;) 
SET vs OTL
Its the amp design,construction as much as the output tube thats responcible for sound quality. Having owned over 10 -45 SET. Probly arround 25 others SET many OTL SS PP etc. I can say that I did not find 45-50 SET to be the best in anyway. I look... 
best WOOFER ???
Eldartford your right many do get mounted in wall. The new super woofers been changed enough to work in massive ported cabinet. Or even OB. These woofers are fast and produce detailed bass with massive subbass at very low distortions compared to s...

Mr T,We all know you greatly prefer stats or Maggies. But dynamic drivers exist in legion that out perform or perform as well as such loudspeakers but sure you wouldn't like any since you found designs in loudspeakers you like. Why not give others...

FOSTEX FW800 31.5IN Super woofer 1 of the best about for bass below 200hz. $3200 ea for new model just released march 14 2009. I would also nominate the fostex w400a-hr $2550 ea. Can be used up to 1800hz. Massive alnico mag advanced design. Dont k... 
Speaker Technology over the last 10 years
I collect vintage drivers and other kit. Sure some of it sounds good and designs are very interesting. But what I listed is what I find has made the most improvement. I still listen to a moded Altec in my office its good not great but fun and driv... 
Cogent horns
Such a large cash outlay for a small persevered benefit that I have not been able to hear or measure when I compared FC versions of dynamic drivers to alnico. Never tried FC comps. But with all things YMMV. I will stick to optimizing other aspects... 
Speaker Technology over the last 10 years
Cone materials, surrounds,spiders, cone shapes, crossover parts, cabinet designs, binding posts sets, internal dampening all have improved for transducers tweeters have made the most progress. But your legacy is not obsoleted by any of these if yo... 
Cogent horns
Hi Paul, If you feel large comp horn systems are worth exploring why not DIY a pair? Even DIY they are costly but not as bad as production. I know you are just as interested in field coils but I find no reason electrically or acoustically to use t...
