SO, not meaning to get off on too much of a diversion, for all the reasons we might imagine, I've also been very intrigued by the idea of building a set of BiBs for FR125's. Seriously strapped for time at the moment, so want to get some idea of how others may have liked the FR125's in BiB's before I commit time to this proj as opposed to stuff on the "Honey-do" list.... I seem to recall that Lousymusician(??) built a set of FR125 BiB's, but I couldn't find any comments regarding his impressions of how they worked out, and have not been able to contact him directly.

Lousymusician -- you out there? How'd you like 'em?? Anyone else out there built FR125 BiB's? Thanks, John
Present and accounted for!

My FR125 BIB's are alive and well, though now doing 3rd system bedroom duty driven by a Yamaha receiver. I wouldn't call them fully optimized (for starters, they are built of plain soft knotty pine boards, hardly the deadest material!), but I have a couple of other speaker projects going too (trying for higher efficiency, heading to SE tubes), so I haven't gone back to tweak them much. As they stand, they have some cork lining the lower front of the inner baffle and the bottom, and Dacron batting in the point, bottom and on the back at the mouth.

If a 4" driver can deliver a bass-heavy sound, it's the FR125 in a BIB! The 14 x 11 den they were intended for has a significant 40 Hz room resonance, and the BIBs took full advantage of it. Fun, but over the top. Even in bigger rooms they have no problem making 40 Hz. That works to my advantage in the master bedroom - they usually get used at low volume, so the full bottom end is kind of like an acoustic Loudness button.

Otherwise, if you like the basic FR125 sound, and crave BASS, the BIB is a lot of fun. They make a big sound that belies the size of the driver and the footprint of the speaker. And they're easy enough to build, so why not knock a pair together and see for yourself?

Default CSS125 and BiBs, MLTL's .....

Hi, All -- thanks for the info and thoughtful responses, (and mea culpa on not having done my research properly, esp since I often critique my students for that! )

Lousymusician -- thanks for the encouragement.

Ditto mis-attribution on the ML-TL -- I actually built the Planet10 bipole variation of Tim Formans ML-TL. I too had originally started off with GM's basic design in my original noodlings, now that I think of it. A new kid and a new business (whose bright idea was that?) -- am I not distracted? Beg me to stay away from important calculations.

Dave at Planet10 -- I'll see what I can do to get pics and plans of the small aperiodic boxes this weekend,

Cheers and thanks again,
John

(BTW, Weren't there 23 "Johns" from Planet10??)

That would be an appropriate number since the number 23 is so special (the law of 5s says so -- note 2+3=5). I never actually counted (i will next time i watch the movie), but certainly all the white Lectroids were John somethingorother.

Hi!
Take a listen to Kings of Leon's album, 'Because Of the times'
Excellent music and a really good recording. Drums have a good smack, small details occurs the more one listen and good separation between instruments.
Wish I had the vocabular talent to describe it more accurate!
Well worth to lend an ear or t(w)o!

.. and John YaYa...
amongst a circle of friends we have many "Johns" so we were all assigned "John" Lectroid names ; I was - and still am -- John Yaya amongst that group of friends.... and lest we forget, that's John BigBooTAY, not BigBootie!

FYI, for those wondering "what the heck?", in the cult film "Buckaroo Bonzai", Lectroids are the nefarious space aliens from Planet10 who invaded earth, all assuming the name "John" so they would of course blend in.

Always glad to help with the useful information.

John Yaya

Just to clarify, the white Lectroids were bad guys, the black Lectroids (with the dreadlocks) were the good guys.

Is it called the "Buckaroo Banzai across the 8th dimension"?
I find it to download it from Demonoid! I've never seen this film! Or I don't remember it!
And I always wonder why "planet 10"?!

If you had seen it you would remember.

If they tried to assemble the cast of that movie today they would likely be on the order of a quarter-billion dollars before even getting out the gate.
