Anyone finding sense in building a 2 way with a 10" bassmid unit, there is an affordable driver that won't let you down in doing this fairly well, the Visaton W250, designed for a larger sealed cabinet.

I had luck with a b102 run wide open and a morel cat378 with its 5.6uf cap.
but yes, pushing a 10" up that high is a struggle...……………..
ampslab liked that morel

Both drivers are about 6db down at 2khz and 12db down an octave away from that (time phase alignment if you are into that), and similar sensitivity, easy peasy.
Surprisingly, I couldn’t hear what was proper phase until I had the morel slid waaaaay back, b102 is deep. Maybe that is why some 6db tweets not moved back for physical alignment are wire out of phase (lipinski).
But, many of those horn loaded domes are 6db down 30 degrees off axis at 10khz, even Devore orangutans.
And what does that mean ?
How about 2 -3 people wide listening width at 7’ away.
It get irritating when you walk out of the sweet zone.
Now I am 10’ and itching to remake them but adding a baffle step b102..........

re 8" and dome HF 2 way. A really good builder I follow favors that combination. He might call eight inch two ways the magic combo. As did many speaker makers where I am from. Companies like Paradigm, who made several stand mount 8" x 1" domes, and 8" 2 ways larger floor speakers. So did sound dynamics. There are a bunch employing 8s of theres also energy. Maybe 8's are the happy medium. Although Dynaudio made 10s work with theyre all too popular 10" 2 way. I happen to be interested in the resurrection a26 over at madisound..
The bump is near 1,300 , same one the a26

10 dB spiking on an awefully smoothed plot......
Copper cap is nice, as is the created flattish z curve making easier x-over.
People love their a26 kits.....

Anybody with first hand experience of the 10FE200 in a sealed cab? Low price and should be easy to cross at 1-2kHz.
The Monacor SPA-110PA seems like a good candidate too.

I had a pair of Yamaha NS-5 with 10" woofer and 1" dome tweeter, sealed enclosure. Liked the sound of them a lot! Good luck on your build
NS-5 ?
used a 13cm 5" midbass.
The old NS-15 ? or similar with 6x9 full range driver and dome tweeter, open back/OB ?
thread was dead for 5 yrs-
The NS-5 I speak of was the first one, in the 70's...two-way...10" woofer 1" tweeter, no midrange. Yamaha reused the model number
Use their little neo 2”, which are better on top off axis than a 4”. Crossover frequency in that range you use the difference in sensitivity to a 10” or whatever size woofer as the baffle step. Then you use any constant-power crossover and the impedance curve stays tube-friendly.
If we are throwing out good small fullranges, one has to mention Markaudio Alpair 5.3 (or A5 MAOP [high end], A5.2, or CHR-50[budget]), or tweaked Fostex FF85wk. Note that the Alpairs are mono-suspension.
I have a partially finished drawing of an A26 variant with small FR, i'd use A5.x as the example. Looks like i got further than i thot, actually did more than 1. i need to finish these off and add them to the planset.
MidTweeters in an aperiodic TL, larger mTs if you wish to push things to higher levels.
As far as dispersion, cone shape and dustcap make a significant difference.

Here's my choice, a Dayton DS270-8 ten-inch...a Beston RT00A-D big ribbon horn loaded tweeter...1600 Hz crossover, 18 Db roll off for the horn. An L-pad to kill of some ten Db or so worth for the ribbon horn. A 170 Liter ported enclosure, an fb of 27 Hz., ...for a bottom end of -2.98 Db @ 24.38 Hz,...
