 Thoughts?

 I'm running two bookshelves right now, small room, and thinking of starting with one of these, then adding a second, and then getting enclosures and amps for my Brahma 15 subwoofers and having them only cover 50hz and below.
 
 I'm much more into midbass and punch then I am subbass, and I'm reading a lot of good things about these.

 Or should I just build my two brahma subs and cross them to 150 and set them near each bookshelf?

[JohnR]

Hm. I know what I think... but did you ever do the modeling on those Brahmas?

[Rclark]

No, outside of work I've had more work.

[JohnR]

Well, the modeling says an f3 of 40 Hz in 3 cu ft. Those are pretty big boxes for a small room...

[Rclark]

That's fine, they'll look cool 

[JohnR]

Well, I reckon you should build them then

I was going to suggest that you might be better off selling those and getting a single 12" servo sub but I see that was already suggested...!

[Rclark]

Yeah yeah I know. But with a pair of Mbms and brahmas just covering the low lows I should be pretty happy no?

I've had the Brahmas for a couple years just kicking around in my closet. Their reputation just a mere handful of years ago was that of sq kings. I know the servo subs are better. Ideally I'll be building a system involving those as my next system. Hopefully the new super v 8" that's coming.

Meanwhile, no objections to the mbm-12 for this system, in fact I've had just the opposite. I'm quite excited to try oneI i believe it will be my next purchase.

[JohnR]

I guess that's the thing - why don't you build the Brahmas? Not trying to hassle you at all, it takes me ages and ages to get around to building boxes, I really don't like that part. However if you're going to purchase an off the shelf unit, why not get something that will do low bass as well? Then you can sell the drivers and get some of the cost back. The total cost will be less and you'll have a complete system instead of putting money into a stopgap measure.

To each their own of course Out of curiosity, where the recommendations you are getting? I'd be interested to read what people are saying.

[Rclark]

I was pmd by a very credible member who suggested in detail that with mbms paired with  b15's (he runs the Tumult, a close cousin of the brahma), that i would have state of the art levels of bass. The mbm only runs to 50hz and is said to give real punch and power up high in areas both subs and many speakers can't give.  By all accounts it gives you super accurate midbass power. Brings drums to life. That's the meat and potatoes for me.

[JohnR]

Yes, but that assumes that you build the Brahmas... in the meantime, you may have lots of midbass punch, but still nothing below 45 Hz. It just seems the wrong way to go about it to me. Hey, you asked for opinions

[Rclark]

I'm using an latec lansing multimedia sub. I'm used to the midbass no subbass sound. I figure I'll take the sound I have now and give it a roid injection. The brahmas will come shortly after to round it out.

[JohnR]

Sure, let us know how it goes

[Rclark]

Yep. Be about a week and half before I go for the first one. Sooner if I find one used. I'll let'cha know

Meanwhile, any credible naysayers with more than anecdotal evidence are welcome to object.

Great, thanks. Don't think anyone will be too keen to help you any more if they are just going to get labeled a "naysayer with no credibility."

[Rclark]

Well.     what I mean by that is id rather not hear from people who've never heard an mbm and only have "theoretical" arguments for or against.

I don't expect any responses 

[JohnR]

I don't expect any responses 

Oh... why? Because nobody owns one?

[Rclark]

Have you seen any threads? I've seen one for sale, that's it. I don't think many people have taken the plunge.

[Rclark]

I'm actually debating holding off on that stuff, continue with the top down theme and just order a Dodd Buffer now that gary is home and I can get one 

 I can run my multimedia sub for the time being. It's having the time of its life being freed of satellites to power and being fed directly off the 2volts of ERC-2 player.

 I kinda want to keep refining my top end. One or the other. Both awesome. I'll decide in a week and a half. I think I can live without real hifi bass for a while longer. Or maybe not.
