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..........

Have you considered two 8 inch per side instead of one 10 inch? I did a 10 inch 2-way years (really decades ago). I used a Pioneer 10 inch poly' cone with foam surround and a Peerless soft dome tweeter. This was called "wide angle" or something, it had a shallow waveguide and could cross fairly low (discontinued now). I got good results here. Audax still makes a tweeter that is really a mid-tweeter, about 1.3 inches and can cross fairly low. Take a look at that; also, the suggestions for a small full range would give good results.
Audax TW034X0 1.3" Textile Dome Tweeter
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..
Off the top of my head,
Generally, a 10" mid-woofer will start beaming at 1,500 to 1,600 Hz
The bump is near 1,300 , same one the a26

WF275BD01_02.. they additionally offer designers the rare opportunity of working with 10” 2-way solutions if paired with a suitable tweeter, like for instance some of the Wavecor 30 mm units.
The designer will have something to work on

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 buildI was looking to build a simple 2-way speaker similar to the BR-1 kit on Parts Express, but instead of the 6.5" woofer, use the 10" DC250-8 in a sealed box. I am familiar with the 6.5" DC160-8 and while I think it is a quality woofer, I am looking for a bit more bottom end without porting (for better transient response).
Looking at the DC250-8's response graph, it seems a good crossover point would be around 2khz. However I know it would be advisable to keep the center of the drivers within a wavelength of each other (13560/2000 = 6.78") that would be physically impossible at that crossover point (Minimum ~7.5"). However, if I used a crossover of 1.5-1.8khz I would have enough spacing to make it work and I think these drivers could cross over in that range assuming I used a 2nd-3rd order.
My question is, are there other potential issues I am not seeing with this design? I may slant the baffle to account for time delay between drivers as well. I just have not seen many 2-way designs with a 10" woofer. I assume this is generally because the cross over doesn't work, but I think it would here.
Please advise me for other problems I may not be accounting for or for other suggestions all together.
Thanks
NS-5 ?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
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,...
