If you want to experiment with MBM's I have 4 2225's that you could try out.They are already in ported boxes, but you could also just do new ones if needed.

Thanks for the offer Beast! Let me figure out my priorities as I've got a lot going on but will definitely keep this in mind. Thanks!

Now major question?

For my three JTR 215RT's

High pass filter at 18htz

Or

Crossover at 18htz and send to my Seaton SubMersives...

I would naturally think the crossover.

But someone tell me otherwise if I need to know something more.
I would crossover to the subs, but not sure that I would set the crossover as low as 18hz. At 20hz, which does a better job, speakers or subs?

A lot of info about that and other good stuff in this thread: Blending ported and sealed - analog vs. digital HPF... and other ramblings....

So, basically what the mic2200 uses is a 12 db BW. It still bugs me that I can't get them to blend with a steeper slope but oh well.

Like I told you the other night, I'm done adding head room. As you noticed I've even reached the point where I don't go all out with the subs even for a demo. The 215's + 8 SI's is finally enough and then some for me.

Now, that doesn't mean I won't someday play with more with nearfield. I like that idea because I think my room is at a point where it is at it's limit and any more bass will start to hurt things. My back wall by the bathroom flexes so bad I can't believe it hasn't cracked yet.

Speaking of nearfield - I think I finally dialed in the mbm-12 to blend perfectly. It has always been fun to play with, but I always felt like it was either too subtle or called attention to itself, I could never find a happy medium so I didn't use it much. Well, a couple days ago I found a great combo of dsp on the 215's combined with distance settings and volume on the mbm. It's so punchy and I can't localize it either! However, it only works for the sweet spot seat - but that's all I care about.

I'll be watching Andrew as he comes up with something (nearfield) for his front row that's on concrete.

That's what I have to do in my room. I also had to play with the sub distances beyond what MCACC set for the distances. I never used MCACC for anything but the distance settings and now I don't use that either.

In your room it could be different, I don't know. Do you have REW or an omnimic?
