Greets!

I started to say this, but decided that the fact that DSL chooses to use the term 'tapped' to define its pipe horn loading technique doesn't change the fact that any TL, MLTL, horn, TQWP with the driver offset along its length is a tapped one.

I stand corrected. As ever, thanks for the clarification Greg.

This reminds me, awhile back I did a fairly high gain SD12 ~16 Hz TQWP design at Bob's request that he said was turned over to you for evaluation, so wondering what the status is.

I don't see why not, per his notes the 206 is essentially a sealed back 'tweeter' in this case, so the drawing isn't accurate. For sure you can't have both drivers venting into the pipe or the woofer will audibly modulate the 206.

Default Hello from Florida...

The reason I ask is attached.....I just finished these a couple of weeks ago after reading the first half of this thread. 84" tall-FE206e-wrapped in speaker cloth. After 23 years of maggies, I feel like I just made giant center channel speakers. I've been wondering about anding more drivers without calling it an array.
Would sealing one driver and then allowing the other the proper line length give a coherent soundstage? Bi-wired? These questions and more........Less than two months reading this thread and visiting your sites and homes in pictures and I feel like
I can build anything.....thanks.

>>> Just one question for all 165K BIB builders :

That tweeter is a great choice IMO.

Also, will that sub design work with the TB 8" subwoofer?

.... FE206E (with phase plugs) would be isolated from the BBIB (BassBIB)
You have those 2 8" drivers scaled down to look like 10 or 11" drivers, they should probably be a bit smaller.
