How do you power these mid bass modules?

[cameron paterson]

Where would I cross these over at? low pass and subsonic filter I mean.

Research among those who've employed them for ideas, never tried it myself as my subs/speakers are fine without the mbms....altho I thought about it at one point.

Do I power this mid bass module like a subwoofer from my second sub pre out? And what frequencies would I run to it? I heard they're great for that kick in the chest kind of bass!

THe designer- is that Erich, from Parts Express?

Isn't Erich more with Denovo and diysg?

Measurements would help with determining your needs. How high and low do you think you want them? 40 to 120? Not knowing your systems room responce its hard to know without trial and error .

Erich is with DIYSG. I have no clue what frequencies are supposed to be run with these.

But you think you need special modules for certain frequency ranges?

 

[cameron paterson]

Well I would like to try the MBM's because that's what theyre made for. What could I do with my mini dsp to get more midbass from my subwoofer? And how would I go about hooking up my fronts and center and surrounds up to my mini dsp?

Your sub is plenty capable in the midbass, even better if it were in a sealed enclosure. As for minidsp and the rest of your speakers it requires outboard amps for each channel.
If I were you, I'd have a complete understanding of what's going on before just throwing stuff like mbms into the fray.

 

[lovinthehd]

Try increasing the eq boost in the ranges you think are beneficial for your sub before going to an mbm. As I said before, it's really about spl.

 

[cameron paterson]

What frequencies should I boost though I have no clue what I am doing.

 

[lovinthehd]

Again, why are you doing it without a goal?

I don't know, but someone at PE designs a lot of speakers.

Jeff Bagby?

I want that kick in the chest bass. Does anyone know where I should tune these at and where I should set the low pass filter?

Did you check with any of the guys who posted reviews there? Or ask Erich himself for some advice?

 

[cameron paterson]

Erich doesn't really know where to run a LPF he said to tune at 45hz though.

 

[lovinthehd]

Might try here for some ideas, not sure if it's the same @andy_c that is a member here....

 

[cameron paterson]

Should I start the lpf at 400hz and go down from there till it blends right?

More like between 100-200hz. There is expected to be a rather significant overlap with MBM and the mids on your main speakers. I can't really imagine an instance where these would be practical except for some real specific issue worth adding yet another single purpose set of cubes in the room. Then it's likely going to take some rather specialized application of filters in which to manage it all.

This ends up being the long way around to instead choosing the right main speakers for your task, and for the high SPL listener, there is definitely no replacement for displacement. If I was so enamored with the chest slam, I'd set up what I had in more of a near field setup and just get used to listening like that, which I do half the time anyway.

I get mid bass punch even at lower listening levels with the Fusion-12's, and even more so along with a pair of sealed, 12" hi-fi subwoofers.
