Opinions experience and recommendations to help me choose between MAOP-7 & MAOP-11

Due to the current heat wave limiting my outdoor athletic activities, I'm feeling the itch to construct a new loudspeaker system. A lot of positive posts on MA MAOP drivers and I'm wondering if I'll be happier with the MAOP-7 or MAOP-11 for use in a small modest size room and preferably driven by an 8wpc 300B based SET amp and or 3wpc 2A3 based SET amp. I've been comparing MA posted Fq resp plots and can't help but think the MAOP-7 looks like it would be the better sounding driver of the two but there is the Sensitivity rating which to me appears low for what I think I'm seeing in its transfer function Fq resp plot compared to the higher sensitivity MAOP-11 ... Thoughts, suggestions, recommendations, please?
Also, optimum box recommendations that'll work in smaller rooms for the two drivers, Thx.

MAOP 7 is based on Alpair 7x, MAOP 11 based o. Pluvia 11.

So the smaller driver likely sounds better and may have greater bass potential.

- website says MAOP-7 is based on Pluvia-7, it's chassis looks like a Pluvia-7
MAOP7_v2

Playback flat up to 37Khz by the world's first diaphragm material MAOP (Micro-Arc Oxidation Process) and the drive unit of Pluvia 7HD Non-standard wideband speaker unit

MAOP 7 is A7.3 based.

If MAOP7.2 is pluvia based one has to ask Pluvia 7 or Pluvia 7HD?

If based on the former MAOP 10.2?

I have no idea, didn't even know there is an MAOP-7.2
Actually, I was thinking the.2 designation is being used like the .2 with the A12p which appears as A12p.2 on some websites and we know that driver is one and the same.

The following link is the MAOP-7 I would get if I decide to go with the 5" driver https://www.madisoundspeakerstore.c...Magnetic Arc Oxidized Full Range Matched Pair
 
That is new to me as well.

Maybe the “meatier” Pluvia cones survive better going thru the electron bombardment process. MAOP are in great demand, so maybe, just speculating, a move to more easily satisfy demand?

From reports the M11 is a very good driver.

A12p which appears as A12p.2

That one i suspect is much my doing. Sometimes the MA line becomes very confusing.

A12,2p made sense, 2nd gen A12 paper cone. Also where we got A6.2m and A6.2p were second generation, metal & paper cones second generation.

Then we got the A10p, and A10p stuck althou given the earlier examples it should be A10.3p and A10.3m.

Add to that the loss of the point part of the name when arrestors started shipping.

Another one… A7.2 was A7.1 with the addition of the super gasket. That is all. But the A7.3 stayed A7.3 thru a number of subtle basket experiments, and ended up being A7 (A) with a small Gen 3 on the box underneath.

So some drivers have more than one valid name. Hard to keep up.

Circling back to the MAOP-7.2 for a bit, I’ve got some headed my way here in Aus, and as much as I’d like to try a FH3, space is a bit tight and I was wondering if there are any other boxes that would suit. The only other one I’ve found so far is the Baby Lab from Woden, is there a compatible Pencil available yet? Or alternatively, is there one of the other 7cm drivers who’s parameters are a close enough match for cabinet design?

I’ve been gleaming ideas from the many great posts on here, previously building a pair of A10.3m CGRs, which currently sit on my work desk. They run off a RPi Zero with an Infineon Hat Amp sitting on it, tucked into one of the boxes, and they sound amazing. Picireplayer and internet radio provide the source.
 
assume order of favorites, what is it about MAOP10 that places it first on your list over MAOP11 and 7?

The low frequencies of MAOP11 and MAOP10 are comparable, while MAOP10 has a thicker sound in the mid to high range. Furthermore, MAOP11 has less sound presence.

MAOP7 and MAOP10 have a big difference in the low frequency range.
The midrange is equal, and MAOP7 has better high frequency extension, but MAOP10 has better realism in the high frequency range.

In my opinion, MAOP11, MAOP7, and CHP-90mica are comparable, and MAOP10 is one rank higher.

Which one has a better low extension? Best quality and presence in bass regions?

The bass of MAOP7 is inferior to MAOP10 in every way.
MAOP10, MAOP11, and CHR120 are comparable in low-frequency extension.
However, the larger the size, the higher the input resistance.
MAOP10 has better low-frequency quality and presence.
 
A question for Dave. If the 7.2 is based on the Pluvia 7, would that make the Storm Shadow Baby Lab a decent smaller cabinet for the MAOP? I’ve put together a side by side comparison of the parameters of the 7 series drivers, and note that there are quite a few differences across the range, but don’t yet fully understand what they all mean and which are significant.
