what would be the recipe for taming boomy bass? more stuffing or less? you can see from my pics how much is in there.
frugel-horn flat pack; what do you think?

Gees, now you're asking me too remember? 😁
I think I would try removing some first
If I am wrong... add more LOL
here is the best pic. the V area was filled with cotton.
Look at page # 17
OK, that is a lot more stuffing; hard to get too much more in now that i've glued on the top piece
another question: the alpair 7.3 has a "cap" that goes on the back of the driver that is removable.
this pic shows the cover (on the right with red label):
This is what MA says about it:
"The rear magnet cover can be removed. The covers magnetic attraction keeps it attached to the main driver body. Simply pull away from the driverʼs main body, no tools are needed to do this job. Removal help those box makers who design shallow cabinets or wish to optimise internal box volumes. The performance change with the cover removed is small, so the installation choices for the end user is optimal."
I have the covers on right now but could take them off. I wonder if that would affect the bass quality.

ooh, this is helpful--thanks
so here is the dilemma: it has been almost a week since i switched to the alpairs. they are still boomy. i switched to a bigger amp and pulled them out from the wall and away from the aiko horns, but neither solved the problem.
i could add more stuffing but, because the cabinets are sealed up, i can add more stuffing via the opening for the drivers but it might be hard to get it back out if the additional stuffing doesn't solve the problem/makes it worse.
in addition, the cabinets sounded great with the CHBs and adding stuffing might make them sound worse.
thoughts?

Is your room treated?
Good question. It’s my smallish master bedroom so no (good thing I’m single). I suppose I could try small diffusers behind the cabinets.
I did move them even further away from the wall and that has helped. Will see if that makes enough of a difference.

Well, aside for the boominess, how do you compare the sound between the MA and the Coral?
I do think the boominess can be tamed with placement or treatments. There was a site called foam factory or something that had some nicely priced absorption products for relatively cheap.
Here’s a crazy thought: why not stick with drivers that need the bass reinforcement of the rear horn? The CHB works with your SE amp and it sounds like it will be easier to enhance the bass you are getting than to control the excess bass of the MA.
A rear-loaded horn is a comparatively elaborate way to reinforce the bass of the driver. The MA may be happier in the Pensil cabinet. While it may be true that the FH3 was designed with the Alpair 7.3 in mind, it may not be the best enclosure for this driver. By the same token, while the FH3 was designed to suit the Alpair 7.3, the Alpair may not be the best driver for the cabinet.
I would also posit that it may not be practical to tune the cabinet for more than one driver due to the cabinet design and construction. This is particularly true in your case where one driver wants more bass and another driver wants less.
Given the CHB’s characteristics, I would consider 70hz - 12khz to be a resounding success. If you want deeper bass (not just more mid bass) then you really will need to augment the low end. If you added subwoofers, you would probably want to extend the high end as well with super tweeters if you wanted to retain a balanced sound.

Except for the boomy bottom end (now a bit reduced) the alpairs have a fuller sound—more balanced. However, the corals have a really nice mid to HF presentation. More air/separation of instruments.
I’m in a Facebook groupwhere there has been a bunch of discussion re absorption panels. Will see if there is

that may be where i end up. i have a nice 8" mirage sub that could fill in the CHB bottom end.
here is a relevant thread in diyaudio comparing alpair 7.3s in frugalhorns and pensils:
MA Alpair 7.3 In Pencils VS MA Alpair 7.3 In FHMK.3
FH3 vs Pensil The time has finally come, the wife has decided the down pipes I'm using as a MLTL for my CHR-70's are just too ugly. I tend to agree unfortunately so its time for them to go. After plenty of reading I am still undecided between the FH3 vs Pensil. The Pensil MLTL is easy to...
post#28 says the poster has his FHs 2 feet away from the wall! i don't have that kind of room in the bedroom these speakers are living in.
the consensus (and dave's view) is the FH is a better cabinet for the 7.3 than the pensil.
I wonder if there is a way i could place some cotton batting in a mesh envelope that i could slide into the the front chamber in the frugalhorn and then fish it back out if i want to use the CHBs. @StevenZ 's room treatment idea could also work; a diffusion panel behind the cabinets could tame the bass.
check these out:
$50 for a package of 6. hang them on the wall with command strips. cheap way to test this out.

love the panty hose idea! i can get cotton batting at joannes. OK, will try that. thanks!
I’ve used this place before. The products seem to be good quality. The Foam Factory sound proofing deadening, acoustic insulation foams, echo elimination, home studio soundproofing foam,
