I could not push the excursion much in a Karlsonator - I'd think it would be tough to get much excursion on wide range material without getting blasted by mids -FWIW, it didn't seem to gargle much on goofy car bass cds ("BASS bass bass") - two per baffle might be fun.

Think I could vertical array them ?

If even a foot off axis you lose highs, I'd think a bit of combing could knock down 1-4khz, yet leave above that untouched..........
And I'd have bass !!!!!!!!!!!!
Well, maybe cross at 100hz for some rumble too.

Fred what ya think ?

Nigel ?
How do your dual pair sound at say 10' ?
Any helpfull combing ?

I'd expect to run a 10 band eq anyway.
And I doubt the combing would touch above 5khz..........

Sure, 12" array. These are 3 of them, 5x12" each: Stereophonic Sound from a Single Loudspeaker

I was told the final version is vertical for all three.

And this is my smaller version with 1x8" + 3x12" : http://www.diyaudio.com/forums/multi...ml#post3304172

hmm. big focused array there.
My buddy said maybe we run series parallel on 4 of them, put an inductor across 2 (baffle step).

That's a crazy setup.

Freddi,
When you say you can't get much excursion in a K'nator, is it because of good cone motion control, or the mids sound too bright (shout) and intolerable? Has anyone tried EQ'ing this driver to get more balanced output? The off axis performance can certainly be improved with a Karlson aperture. My measurements with a K aperture on a small XKi shows fantastic polar coverage - 5dB variation at 45deg up to 10kHz. This is on a small 3.5in driver and small K aperture but it has to help even for larger apertures.

that Fane is stiff plus there's not a lot of motor strength so I think it would be difficult to destroy on an open baffle - it actually sounds pretty good (a bit 'warm') in the Karlsonator12 and played hiphop relatively cleanly without noticeable "gargle" of vocals or high frequency sounds. The Fane also sounded clear without artifact in a regular slit vent Karlson 12 but was devoid of any real bass in that case.

Cone control overall seems good in the Karlsonator12 as my Nirvana stamped framed Super10 had good dynamics and reach - I've seen it jump in a bass reflex far from linear excursion - I think the Kalrsonator went a bit deeper than Super10 in K15. (Super10 in K15 is "warm" & "musical") Also the Karlsonator was the best so far for 12LTA but I've not run 12LTA in K15 as have plenty of stronger coax.

I'm impressed with Karlsonator12 - need to try a Beta10cx or powerful 12cx.

Not in a karlson, think the sweet spot is 3' wide (total) at 9' ?

I think I remember you saying rain sounds different a foot off axis 5' away......

QTS probably around .8, 52oz magnet.
Only 1.5mm of overhang, 3mm xmax, plus adding 20% top plate means 3.5mm.

I think legis said on the fane 200lt, it went from 3 to 5mm with no changes.

Fred, can ya measure the impedance of it ?

the shift of timbre on rain recordings was in reference to L.Cao's F6 - its a fact of life compared to a little dome tweeter in a regular 2-way.

Norm - did your Fane arrive?

nope, should be ordering 3 tomorrow night.
Thanks for the measurements.

2.5-3ft3 sealed should make a neat center channel.
