RE: MMGW as a midbass driver

Posted by josh358 on February 22, 2010 at 20:52:39:

Love the idea of the stacked MMG-W's! Though I've had second thoughts about them because I assume they've put the resonance in the 100-200 Hz region, and I know they've tailored the response curve to take advantage of the wall mounting, meaning they'd likely require a bit of a boost equalization.

Here's a picture of my listening room. I'm afraid it doesn't show the precise situation and I can't take another right now because the room is empty while the floor is being refinished. But I think you can see that the space is very constrained -- I can't move the listening position back because of the rear wall, and the projection screen means that the speakers can't be bass driver in. If they could be, I wouldn't have a problem. So if I'm to use wider speakers they have to extend towards the radiator on the left and the fireplace on the right. I could probably fit 2.x's or 3.x's physically, and I've been sorely tempted, but I'm concerned that the sonic results won't be good, since everyone seems to agree that you need a couple of feet of breathing space between the side wall and the speaker and I don't think I even have that, and the left corner of the wall behind the speakers is already interfering with imaging.

Some other possibilities I've been entertaining:

- Put the Neo-8's next to the MMG tweeter and use them for the midrange, crossing over from the midbass panel to the Neo-8's at about 200 Hz and then using the quasi ribbon tweeter above say 5K. Easy and cheap, would fix the MMG's midrange problems but of course not the bass.

- Ditto but use the true ribbon instead of the MMG tweeter (not sure how much I'd gain from the push-pull Neo-3's vs. the MMG quasi ribbon if I crossed them over at 5K). So I'd have MMG midbass/Neo 8 mid/true ribbon tweeter. Could be added to the above setup by disconnecting the quasi ribbon tweeter and flipping the driver panel. Then I'd use the bass panels from the source of the ribbon speaker as previously described, so you'd have a four-way kludge. Five, if you include my sub.

- A pair of 2.x/r's split in half, so I'd have the 2.x ribbon/Neo 8/2.x woofer. I'm not sure if I could acommodate the width, the 2.x is already 22" and I'd need 4" for the mid so I'd end up with something about a foot wider than the MMG's.

I don't want to add a dynamic driver, I've never heard a hybrid system that really worked, not even the big Infinities. Ditto for not wanting to use the MMG's or 10's or MMG-W's up to 700 Hz or so so and crossing over to the Neo-3's -- I'm aiming for something that sounds more like a 20.1, or the above 300 Hz part of one, anyway. As much as I love them, the small-diaphragm, single ended quasi ribbons don't have the smooth on-axis and polar response, clarity of at high levels, transparency, and imaging of their bigger brothers. Whereas between those amazing waterfall plots and their push-pull magnets I believe you when you say that the Neo-8's sound almost like stats.

Still haven't had time to check out all the drivers on your driver list -- I've been too busy trying to get these renovations finished. Probably best to have a place to put the speakers before I get them . . .
