Well, more straight talk from Arny ... a loosely chosen entry point!
OTOH, I've been following the thread, as I've a pair of B139's too;-)
AAMOF I hauled them out of a pair of small "TL"s I bought (with early
T27 variant, B110 (unknown label-off variant)) and reduced the cases
to face-down "speaker stands" interim because they sounded so bad,
with old stuffing etc, and besides I needed a temporary replacement
for the one blown T27's in my kitchen Kef 104ab set - but I digress!
Straight talk or not, I've total sympathy with the OP's desire to do
what he can with what he has, especially with budget considerations,
and I'm saving the B139's (and the B110's in case an alternate idea
for a better cabinet arrangement .... looking at the really basic TL I
bought, it could be turned sideways and possibly extended ... as per
http://www.t-linespeakers.org/design/foldings/tttl.html ... maybe ...
But my main point was going to be ... and I hold this out as a
potential future project of my own, all comments appreciated;- -
what about considering the "coffin" dual TL supposedly sub at
http://www.t-linespeakers.org/classics/coffin/
and especially, obviously the details at the "Perfectionist Audio"
link therein,
http://www.hogheaven.com/diyaudio/su...PATL/patl.html
as a possibility for using a spare pair of B139's up?
OK, it requires a little work in the timber dept, but why not?
It might seem to have capabilities beyond the usual, anyway.
