They do not think any single driver can function at all over 5 octaves absolute max.
(Shhhhhh! Don't tell anyone about this or they'll flame us FR forum goers without mercy!)


AHEM! Very nice compact setup you got there picowallspeaker, mind sharing some measurements and xo settings?

A sub used with most full range speakers is usually crossovered so high it's a woofer, and you end up with a 2 way speaker.

Here is one:

Coaxial Speaker Build Thread with FaitalPro 6HX150

And to answer your question: I don't know.

My surrounds are an 8" coax with a 15"midbass.

I've also built a number of active Tannoys with either a 10, 12 or 15" coax with a 15 or 18"pro midbass. Made for smaller enclosures and much better midbass and midrange.

Thank you Charles, I hadn't seen that thread. I'll have a read now. Mine are AE TD15X and Faital 8HX200.

I understand about the handoff.
Currently, i am sensitive to x-over in voice / bass range.
Middle c is what 440hz, where we would tune for band in school ?
Much is happening an octave below that.

But i had luck with thiel cs2 (6db time aligned 3-way), but woof was far from mid/tweet, so 10' distance + was beter to my ears.


And yes, this thread may get hot !!!!
yes, the handoff between large woofers to small mids xo at 300hz seem to be tricky and I do hear some disconnect in all the 3 ways ive had: JBL lsr32, Genelec 1037a, various vintage jbl and every speaker Ive heard using big woofer and small mids.

a geithain arrangement seem very interesting as a solution when trying to "match" big woofer to small mids...

or maybe simply have all the mids up to 1 to 1.5 khz covered by a large woofer then crossed to a HF driver able to handle low XO (large format tweeter- horns, ect) but then this comes with its own issues.

I've got a Faital 8HX200 + 8PR200 build coming up soon. Design goals were compact, versatile placement options, highish sensitivity/low distortion. Will be used with subs.

yea, currently I'm in love with short horn crossing 1.1khz-1.2khz, but yes, a 12" is not as detailed as my pair of morel 6" with copper caps......

But I get a lot of volume, bass more than 7' from the box, and I'm not paranoid about blowing $240 6" woofers either.

I'm looking at doubling up the 12's for even more midbass.
