MBM12 PLACMENT - Pics Included

[Splotto]

Hello:

After reading several posts here and on AVS, in combination with me already having the bug to tweak my setup, and having the wiring contractor coming soon to do some behind-the-walls wiring (the one benefit of being in homebuilding right now) has me interested in adding the MBM12 to my system.

As with the thread about the placement of my HO, the placement issue will be the problem.

I have provided a pic below that shows the best possible placements for the MBM.

The first location would be on the right of the end table to the far right of the picture.

The second location would be to the far left of the picture at the end of the couch behind the end-table (where the green roomba and flip-flops are sitting now).

I could have the wires run through the ceiling and down the wall to exit under the couch so an exposed wire wouldn't be a problem on the floor.

The second picture shows the room from another angle.

I appreciate any thoughts.

Place it anywhere the cat likes to sleep :D

Splotto, for your second proposed position, would you be able to actually use the MBM-12 placed next to the couch in the endtable position? Or as an alternative, would you be able to move your couch about 1 foot into the room so that you can place the MBM-12 sideways behind it? :)

As with the HO issues before, moving the couch is an absolute non-starter for me with my wife.

I would either put it in position 1 next to the end table (far right) or move/replace the endtable in position 2.

I think I would prefer option 2 in the endtable position (port firing forward and amp to the rear, with MBM placed next to couch), but it wouldn't hurt to try option 1 as well just for comparison purposes.

I figured that my "alternative" option would be a no-go with your wife, but I just wanted to see how far you were willing to go :D

My final option is to get 4 more HO's and replace the coffee table. :-)

Laughing out loud!!! That would do the trick too :D

Peter:

Thanks again for all your help. It's great to have a vendor who makes their team availalbe like this on a great forum.

Keep up the good work.

My pleasure, and thank you for participating! You guys are what makes this a great place to be, and deserve most of the credit!

You know, you might not need 4 more VTF-3 HO's, 3 more would probably be more than enough :D

Keep up the god work.

I have a lot of extra work to do to get to that caliber of work! :D I really do appreciate it though, thanks again.

Then I would be jealous!!!! :(

(and four MBM's?)

[Pete_Hsu]

I'm jealous of both of you. There's no way I can accomodate even one VTF-3 HO at the moment!

I like your setup. Looks good.

I saw your garage view and I thought it looked familiar....where in FLA?

Then you have too much damn furniture or maybe a WAF problem that need fixing.......diamonds always do the trick :D

Ok. Not far. I get down to Palm Bay once in a while for work.

Nice down there.

I am in Sanford/Lake Mary.

Neither of those are the problem, it's the neighbors. Maybe I can bribe them with some 4" ports or something like that. I'll even throw in some port bends if need be. :D

I have used near field midbass for many years, on my own. This came about because I wanted mega MEGA output down low...and when you design a speaker for that, it may no longer have flat response to say 300 Hz like most conventional subwoofers. More of a specialist so to speak. So teaming it up with another specialist makes sense. I appear to retain the at-the-couch record for the loudest, clean, common bass frequencies. Which was high 130s dB @ 25 Hz with around 5-6 % THD before power ran out. Under 120 - 125 dB the distortion was essentially nonexistent. At under 110 dB it was a small fraction of a velodyne 18 for example (a vel can't do 120 -130, LOL). I crossed over that sub at around 35 Hz +/- most of the time. And by not having to worry about >35-40 Hz, I was able to find nice benefits below that point. Hint, hint!

Anyway having had lots of experience with MBM type scenarios I can note the following:

* It's best to be able to measure live on a PC screen the various interactions of the speakers when you integrate them. I use a tablet PC, whose mic I have calibrated, for quick stuff. It's the size of a hard cover best seller novel.

* Things like crossover slope and frequency can be played with, staggering for example. There will be a few possible, reasonable setups.

* Nearfield midbass tends to provide the listener with notably more tactile energy. This can be a plus or a minus, and preferences come out, it's not a right or wrong thing necessarily. You are almost certain to notice a big change in that aspect of the bass experience, however. I like it!

* There are many more setup options to play with than usual, so even if you are experienced, expect some head scratching at first.

* In some cases...an under the couch woofer can make sense. If the MBM was thinner...this could be tried by the OP. I'm sure his wife would like not seeing another box in the room. Many couches have a stapled on liner across their bottom cavity. One of my couches has about 8-9 inches of clearance from floor to frame if the liner is removed. Just a thought. And an MBM under there will clear out a sleeping cat real fast.
