They recommend the Seos12 for 8inch woofers and higher however it will fit perfectly in my design. the box should be approx 34-35cm wide it means the tweeter section can have the same width. Can I combine it with 6,5 inch driver(for ex.6nd430)?

Have a look at the BMS drivers.

5kjz is too high for a 6.5" midrange IMO as after 3khz or so, it will begin to beam...unless that's a design priority.

As to tweeters, just about any pro audio CD will have substantially lower HD than either of the domes you mentioned. At your intended crossover point, a 6-8" waveguide will hold directivity just fine, and I'd suggest the 18sound XD125 as an introductory horn/cd driver. It's quite easy to work with passively. Of course, there's better....read more expensive options but not sure if you want to start there.

Another fine option of you choose the right mid and cross higher would be a true ribbon...say the Fountek Neo2.0 with avg effiiciency of 95db or so. After baffle step, it's a good match to a 95-99db midrange.

Horns
These are the (expensive) fiberglass versions.
I haven't found the cheap plastic ones in Europe yet.

True, the waveguides can be ordered in fiberglass from Autotech. The compression drivers are (I believe) sourced in the US though, and the 12" SEOS waveguide variant as well as a few other smaller types are being manufactured in injected plastic here in the states too for a much lower price than the fiberglass. Don't know how the shipped prices shake out against each other for someone in Europe.

I was looking into it a few weeks ago and I only found 2 pieces available in Europe at some place after searching the whole internet.

There you go:
Audax PR170MO Professional woofer, replaces MHD 17 HR 37 RSM, MHD 17 HR 37 TSM, PR 17 HR 37, PR 17 HR 60,PR 17 HR 70, PR 17 HR 100

They say 'in stock' but not how many.

Yesterday I have been at BVAudio to compare F3B, F3ROY and MAX. It is not easy to tell which is better.
F3ROY - Subjectively the deepest bass, less precise than the others, can not feel the reserve in the power
F3B - the best treble and localisation from 3, I think the midrange was also the clearest...however....I missed the bass and had a feeling of small coloration (maybe missing baffle step compensation???). I had a feeling that sometimes the instruments(saxophone) and vocals had no basis.
MAX - most natural sound, little bit more bass as F3B but less precise. Also less precise localisation and little different trebles. THe midrange was not as clean as F3B.

At home I playd the same songs on my Seas TRYM + LAB12...
Compared to MAX and F3B the trym had less reserve in the power, on the comparable levels I have had a feeling thet the tweeter is clipping. THe bass is deeper and the music have bigger body but not as precise than MAX and F3B but not as "boomy" as F3ROY. Localisation is more less comparable with MAX. The midrange was cleanest of F3B than MAX ---TRYM ----F3ROY.

SO I have some mixed feelings. There is no clear Winner.
At the moment I have 2 options for the next speakers:
1. 15P1000FE+6,5inch midrange (not decided which one)+ TPL150 (Crossover 220-250Hz and 1500-2000Hz) the box like Focal Utopia
2. LAB12+ 7-8inch midwoofer (no idea) + TPL150 (Crossover 80-120Hz and 1500Hz) Probably the LAB12 will be on the side of the box or on the rear.

Can you recommend some 7-8Inch midwoofer with high efficiency and low distortion (maybe PA) which can be crossed at app.100 and 1500Hz?
