The assumption that the A7.3/A7p can fit a smaller box is correct. It has to be specific to the driver thou. There is a standard milliSIze box (4.7 litres) for each of these, i haven’t tried smaller.
milliSize me...
We have put many drivers in this box size, changing only driver mounting details and the vent spacer. Some of the plans are free, but for the larger drivers (where a CGR was released for free) they are part of the paid planset.
Between the A7.3 and the A7p we give the edge to the metal cone. The A7p has some HF issues which do seem to go away with extended breakin (>1000 hrs) but we only have one example. Even after the long breakin the metal cone driver is still capable of greater DDR (ability to reproduce small detail). I am not saying the paper is a bad driver, we have clients that love them, just our personal preferences.

Thank you. I don't like the visual aspect as much as the 7 litre vented 0v81 shown in post #24
I'll probably used the aforementioned 7 litre vented 0v81 with a 4-5" driver (not the 10P)
These are nice too, thank you
If I don't find the previous plan suitable I'll contact you to get a paid plan for whatever driver I end up with.

That box only works for the A10p.
Planset subscription does entitle you to a custom version. The 7 litre can likely be modified for use with A7.3/A7p/A10.3.

zgtc - note that #24 in your above reference had photo of "Compact Floorstander" (with EL70), while the PDF link was for small vented box for the A10P - which I don't recall building or hearing a pair of.
I wasn't clear at the time which driver you'd settled on. Note that Mark's model designations reference the effective cone size, not frame dimensions - something that continues to confuse DIYers and some resellers. The A10s and Pluvia11 are 10cm (~4"), while the A7., Pluvia7 and CH- 70s are 7cm (~3").
I also don't recall whether you'd indicated use of any bass augmentation (i.e. "subs"), but returning to my earlier comments - in a room size as indicated, I'd suspect the A7 / modulus86 combo would be just fine. Very nice "sounding" (i.e. it doesn't have one) amp that I wouldn't mind adding to my harem, and certainly does more than adequate job with the Alpairs. The floorstanding boxes tend to deliver deeper bass extension, while the smaller standmounters - particularly the trapezoids (finickier build), deliver excellent imaging.

A box i quickly did for zgtc to see if A10p would fit this small a box.
Confusion even here. P11 & A10x are nominal 5.25: drivers (with 4” cone diameter) and A7/P7/CHx-70 are nominal 4” drivers with 3” cones.\\
dave
That was my point above - approximate / effective cone size, not frame dimensions . Other makers aren't much better -Fostex for example, classifies the FF165WK as 6.5", but the through hole is 146mm (5.8"), and the effective cone diameter is 130mm (just under 5 1/8").

Wow, so that PDF was made on purpose for me? I feel in debt now. Is it OK to contact you through DM?
Well I just look at external diameter in specs, I don't even follow nominal size since I will need to make it into a box depending on physical measures, not specs
Thank you for the appreciation anyway, just in case. Thank you again
Yes I think it makes sense to pair A7 with modulus86.
Is it too much of an abuse if I list my final list of drivers below? I've been reading quite a lot these weeks, but too much info sometimes is worse than having two options
- Markaudio Alpair-7 Gen3. Everything I read about it is good. A bit pricey but I would dismiss the WAF
- Faital Pro 4FE32 / 4FE35: I read in a post linked above that 4FE35 sounds very similar to A7.3 ("the 4FE35 sounds slightly more forgiving with more raw recordings, the A7.3 having slightly clearer highs") for 1/3 the value.
- Dayton Audio RS100-8: anyone has any info on this driver?
- Seas Prestige FU10RB H1600-08: anyone has any info on this driver?
- Scan Speak 10F/8424G00: maybe a bit short on both ends (more a mid than a FR)?
Thank you
I've only heard two from that list - and yes the 10F is an excellent midrange, with no detectable character to my ears, but at $95are $10 ea more than the A7.3.
Just to further confuse you, a newer brand along the same design philosophy as the SEAS/Scanspeak to consider would be SB Acoustics :: Official SB Acoustics Website

You inspired it, but i was curious about whether the driver would fit that small a box. And now i have a simple box half-way between the deciSize & millSize that i can use for a number of drivers.
DM = Direct Mail? Yes, only way i can be acsessed, address at one of the websites in my signature.
dave
Alpair 7.3 now with the addition of an arrestor to warn you you ar epushing too far. My favorite driver ever so far
Drivers on my list to try. After the TC9 fiasco i am more cautious with rave reviews on drivers, but these Italian made units could well trade cheap baskets for low price.
No experience. I always approach PE housebrand with caution.
Qt too high for anything but an OB, or maybe a biggish aperiodic box.
Very smooth, but really an extended midrange driver. Pretty as well as expensive. Goes into a really cute little miniOnken that would really give a challenge to a Bose cube. There is a cheaper one (still not inexpensive) that is more of a FR.
Most of these are 4” but the 10F is really a 3” which would imply consideration of the Alpair 5.2/6.2 and the Fostex FF85wk, (which i have heard & like) and possiblly the 3” Faital (which i haven’t).
dave
Check the coming soon tab on the manufacturer's website, and as well note that their 4" midrange models ( SB12MNRX25-4 below) show at least as much extension at both ends as many "full-range" units. The Satoris are something else again.
will do, thank you
Only real drawback is price, but apparently it fits like a glove por the purpose.
Main doubt for driver selection is this. They even sound nearly as A7's at 1/3 the cost, according to other people in the forum.
Didn't know it a PE self brand. In any case, reviewing the graphics they seem more a mid than a FR.
Noted, off the list then.
I like that box design. Will contact you.
Coming drivers are not that pretty, and current drivers are 4Ohm. Price is OK, but overall I would prefer A7.3, Faital or TB, they seem adequate for the job and look much better.
I nearly overlook this one. I was focusing on 4-6.5" drivers, but... would I get a good enough system with a 3"? Given the room size + Mod86 amp power capped at 28W. Gut feeling tells me I'd need to force the amp a bit more, but I don't know if there is any interesting 3-4" alternatives (besides those 5.2/6.2 and FF85WK) that would also allow me to make the enclosure much smaller and still get good sound.
