For those who have never done a DIY kit before, I HIGHLY recommend that you pay the extra money and have Meniscus assemble the crossover. Also, the precut flat-packs are the way to go as well unless you are 100% sure that someone you know can duplicate the measurements or modify them so that the internal volume is identical. There's a decent amount of labor involved in a scratch-made cabinet and given that Dennis has a line on Baltic Birch flat packs, you'd be hard to beat those.

As well, 3/4" Baltic Birch is not cheap and is sometimes difficult to find.

But if you take your time and do it right, DIY can turn out pretty good. For instance, here's a Carmody Classix II that I just got done with. I gave them a "vintage 70's" look because I wanted them to look like they belonged with my vintage Marantz, plus it was a good match for the rest of my furniture. They are a dark gray painted front and Cherry/Mahogany stained Maple veneer.

To follow up with my speaker problem, the driver is dead. Somehow the used amp that I purchased blew the speaker. So I have to take that apart and check the internal fuses. I never turned it on without a new fuse on the right channel, but it still fried that driver after blowing the fuse. Dennis is sending me a new driver and I'm getting the amp repaired if it's not the internal fuses. I should be back in the game soon.

I'm going to have to build another pair of these soon because they sound amazing!!!( Need them upstairs as well)

Thanks to everyone that helped and thanks to Dennis for being extremely fast to deal with the situation. If you've got the time to build these, just do it. I don't know how you could get better than how these speakers perform...or I don't want to know the price your have to pay to get better sound.

Things would have gone even faster if Madisound hadn't sent you the wrong woofer. You should still get the right one this week. I've redone my web site to eliminate everything except the BMR page and links to the kit suppliers. You should feel free to email them about any questions or concerns you might have. I'm still hoping to get pics of the flat pack in a few days, and shots of the finished cabinets in a couple of weeks.

Dennis, while I understand complete, I always enjoy visiting your web site and seeing it with a full compliment of speakers, even if you couldn't buy them. Seems like just before your "retirement" you had Phil3, BMR, mini Phil harmonitors and AAs? Maybe the Center for the BMR as well...

I'd like to see the old speakers up there because, for example, I have the New Philharmonitors so it would be nice to see the spec and the philosophy behind them as there is no literature about them anywhere. Suppose I (or others) decide to sell them, buyers would like to know too. (Like a link - Formerly Produced Models.)

Points well taken. I'll get a link to the old pages posted on my site for people who are just curious or who might want to try and find a used pair for sale.

Dennis, thanks for doing that. Do you think you will ever have plans for the Philharmonic MTM Center and/or the new Philharmonitor available to build. I suspect that the BMR will sell nicely so there may be motivation for Meniscus Audio and Speaker Hardware to expand their offerings.

I'll have to see how it goes. Meniscus is still supposed to offer the AA monitor as a kit, but it would make more sense for Parts Express to offer it as an upgrade to the BR-1. I still can't figure out why they're not interested. Maybe a write-in campaign would work. Anyone want to sent off 1000 emails to the PE marketing team?

Hidden in plain sight! I was looking for something a little less subtle, though it may be more obvious to non color blinded folks.

I am also interested in a floor standing variant. Is there any information available on the cabinet dimensions for putting the BMR drivers into a floor stander? I love the look of the old Slims. I get nervous about separate stands and monitors when the 70 lb puppy is in a playful mood.

It's a DIY...you can do anything you want with the cabinet/stand. Put a divider into a floor-standing cabinet to maintain the proper internal volume, but it'll look like a floor standing speaker.

Sorry if I offended, _tk, I'm a noob and I wasn't very clear. I do realize that you can maintain the volume of the original on top of the rest of the tower. I meant I am curious as to whether the interior volume of the driver compartments of the slim were significantly different from that of the Phil BMR or if it is as you said, similar but essentially with a pretty stand already attached. I believe from what I read about the slims they were discontinued because their performance was nearly identical to the BMRs.

I am basically locked in on the BMR kit, but am trying to decide my best course of action regarding custom cabinets or those that will be available soon.

My recollection is that the Slim Tower was discontinued because of its similarity to the Salk Songtower

The Slims were a transmission line design and used the entire volume of the tower cabinet. They were discontinued because they were too similar to the the Salk Song 3's that I designed for Jim. I have my own design for a WMTMW BMR center channel, but it doesn't use the Scan woofers, nor does Rick's. The cabinet would be way too big. Mine uses the excellent Seas U16 6" woofer, and Rick's uses an SB Acoustics woofer. The only design I have for a multiple woofer BMR is a huge tower that would cost a fortune and is still experimental at this point.

How much is a plane ticket again?


OK... Revelator woofers? Looks larger but I think 7" is where ScanSpeak stops doing that slice. And is the Raal a 70-10, or is it the 70-20?

Those are 7" Revelators. This particular design requires a very complex low pass roll off for the woofer, and the Scan 8545 I use in the BMR monitor isn't smooth enough above the crossover point to achieve the desired slope geometry. The tweet is the 70-10. I prefer it to the 70-20 because of its broader dispersion and you have more options to tailor its high pass roll off. The 70-20 is designed to minimize the number of components needed to achieve a LR 4th order acoustic slope, but that's about all you can get with it. The 70-20 is mainly useful where a low crossover is required. I'll keep my neighbor anonymous, other than to say he'll be really pissed when it gets warm enough to open his windows.

I guess now the question flips to do YOU have an air bnb room in your house Dennis?

Is that going to be a Salk speaker?

The tweet is the 70-10. I prefer it to the 70-20 because of its broader dispersion and you have more options to tailor its high pass roll off. The 70-20 is designed to minimize the number of components needed to achieve a LR 4th order acoustic slope, but that's about all you can get with it. The 70-20 is mainly useful where a low crossover is required. I'll keep my neighbor anonymous, other than to say he'll be really pissed when it gets warm enough to open his windows.
Sounds intriguing, Dennis! Keep us posted...
