Short review: Philharmonic BMR monitors

As promised in my other threads, what follows is a short review of my new Philharmonic BMR 3-way monitors, built by Dennis Murphy with cabinets by Jim Salk. Customizations are front facing slot ports and Audyn Plus capacitors on the crossovers (high and mid circuits only -- the bass circuits use Dennis' standard caps). Placement is quite close to the back wall (about 8 in), toed in slightly toward the listening position but still crossing well behind me.

I bought the BMRs after auditioning a number of monitors in the 1500-3000 price range (and a few that cost a lot more). These included Revel M106, Amphion Argon3, Proac Tablette Anniversary, Paradigm Prestige 15, KEF R300, Robson Regis, Totem Element Ember, Sonus Faber Olympica 1, Focal Electra 1008 BE2, and B&W 805 D3. Unfortunately I did not have the opportunity to do any head to head A/B comparisons, but I did come away with several impressions, a few of which I'll mention below.

After wiring up BMRs and placing them on my sand-filled Ascend stands, the first album I played was Duke Ellington's Recollections of the Big Band Era (redbook, ripped to ALAC). This is an album that I love and am very familiar with. I was struck instantly by the growl of the trombones. They had bite, and I mean that in a very good way. They sounded like brass is supposed to sound. Brass isn't liquid or laid back. It's in your face. The BMRs did not get in the way at all. I felt like I was in row 1! They also are fast enough to keep pace with some really upbeat horn lines. As a point of comparison, I felt that the much more expensive Sonus Faber Olympicas were too slow to play convincing brass, while B&Ws had the right pace but couldn't represent the timbre of the brass instruments as honestly.

After reveling in Ellington for a while, I put on Eva Cassidy's Live at Blues Alley (redbook, ripped to ALAC) . My favorite songs on the album are What a Wonderful World and Stormy Monday. I already knew from my earlier listening sessions with Dennis that these speakers can play deep, but was still struck at the authority of the electric bass. However, where these speakers really stood out was on the soft treble piano line in What a Wonderful World. These were some of the only speakers I auditioned that I felt presented the piano line totally naturally: airy, without any artificial sparkle, but still textured with a piano's roundness.

Switching over to electric blues, they had no trouble rocking Stevie Ray Vaughn and Albert King's In Session album (192/24 ALAC). Again, totally natural. The blaring guitars are not tamed down in any way, but nor are they fatiguing, and the texture is pure electric -- I could almost feel the current pulsing :)

Regarding the bass, unless you are listening to rap, electronica, or pipe organ, or you need a system that does double duty as a home theater, you don't need a sub. I happen to have a TV in the same room, and I do use a sub for movies, crossed at 38 Hz. For music I lower the crossover freq to 20, effectively taking it out of the signal path. I may discover the odd track where a sub has something to contribute, but I did not feel it was necessary for any of the music I listened to prior to this review

Imaging is quite good, but not the best of the lot. I felt the B&Ws and Amphions both imaged with a touch better precision. The BMRs certainly can resolve the positions of instruments in the orchestra as well as I feel I can do when I'm listening to live music, but the hyper-precise imaging that to me feels unrealistic isn't there.

About build quality -- these speakers are heavy! I didn't weigh them, but bringing them upstairs from my car, one at a time, was no easy task. They absolutely pass the knuckle wrap test. Also, the wood finish is furniture grade, top notch, and Jim Salk will do pretty much any wood and/or stain you want. Neither the picture here nor the pictures in my other thread do the speakers justice.

In sum, I'm really happy with these BMRs. They sound extremely natural and honest, they are fast, putting the transients right where they need to be, and the bass will make you think you're listening to floor standers. Also, the highs are quite detailed without being fatiguing. I haven't noticed any 'artificial' detail. When the music calls for it they can be sweet, airy, and liquid, but they present brass horns and electric guitars the all the grit they have in real life when you're at a concert in a small club and the instruments are right there in your face. I won't go so far as to say that they crushed all of the other speakers I auditioned, including the pairs that cost 3 times as much, but I will say that I have absolutely no feelings of remorse that I did not have an extra 4000 in my budget to by something at the 7000 price point. These speakers are just what I wanted.

Other equipment in my system includes:
- Sony BDP S7200 serving as a source (DNLA renderer)
- Hegel HD12 DAC
- Adcom GFP-750 preamp
- Marchand XM66 variable crossover
- Odyssey Stratos Plus amp
- Outlaw LFM-1 EX sub

Glad you are delighting in your new speakers. I think they are an amazing value in a high quality speaker!

If you know the sound, an aggressively played (as it often is in big bands) trombone is definitely a good test for speakers. If you look at the spectral analysis below, you will see just how much of the spectrum is captured with all of the harmonics (which appear to get up to around 12kHz!). Also note how the highest frequencies drop right after the attack of the note. If played aggressively, these higher frequencies are retained.

Hey KEW, thanks for sharing! It's very clear from your spectral analysis why reproducing a trombone is so difficult! Not only do you have the overtones to contend with, but also the attack and decay.

It's always nice to know that I'm not just hearing things in my head :)

Thunder240, thanks for the nice review. I'm glad you took the time to visit Dennis and hear his designs, and it's rather clear you're glad too :).

What's the veneer in your speakers? It looks good.

Bummer. I was hoping you wouldn't like them so I could take them off your hands. Seriously, they really seem to hit the bulls-eye of performance/value/aethetics. Thanks for the review.

Oh, given their ported box alignment, you might want to consider a much higher crossover frequency when you employ the sub. It's difficult to achieve a seamless blend when speaker woofers, ports, and subs are to varying degrees out of phase, but crossing at 80 would sidestep such potential issues.

Thanks very much for your articulate review. My objective in designing the BMR's was to provide the performance strengths of a 3-way tower speaker in a smaller, and therefore less expensive, cabinet. And, of course, I wanted to showcase the unique sound of the BMR driver, which has much broader dispersion than the bulk of midranges currently available. With less of the midrange output focused forward, it's possible that the BMR's imaging might not seem as pinpoint as that of a few other speakers. That's just a guess--I don't think we know exactly what design characteristics contribute to subtle differences in imaging. Jim Salk's dark-stained walnut cabinets are certainly worth the added cost, but in a few weeks the BMR's will also be available in pre-fabricated cabinets that will bring the price and build time down substantially. Thanks again for taking the time to post your experience with the BMR's.

@Swerd the veneer is walnut with a black "sunburst" stain added such that the corners and edges are darker than the middle areas. With the stain, there is quite a bit of gradation.

@ski2xblack Thanks for suggestion regarding crossover point. I've played around with the various adjustments on my XM66 (Q, phase inversion, gain, and frequency within the range of about 35-50) while generating test tones using the Signal Gen iPhone ap, but it didn't occur to me to try a substantially higher crossover point. I'll definitely try your suggestion and see if I like the result any better. It's easy enough to try it out. Also, at some point I'm planning to pick up a calibrated mic and run REW to see if I can do any better with the help of a computer than with just my ears. But it does seem like a shame to move the mid bass over to my sub rather than using the 7" scanspeaks on the Phils.

@Dennis Murphy Whatever possible loss of imaging precision is attributable to the BMRs wide dispersion, the wide sweet spot more than makes up for it. (I forgot to mention that in the review.) You hit a home run with these speakers. Thank you!

Congrats on the BMR's.

I came really, really close to ordering a pair a while back but I decided against them. Ironically, one of the reasons I passed on them was because I was going to place them almost as close as you have yours to the front wall (flanking a fireplace). Since they already have deep bass, I was concerned that I wasn't going to like the effects that room placement was going to have on their presentation. I've had other "fuller" range speakers in that spot and I was looking to avoid that. If it hadn't been for that reason, I probably would have given them a shot. I believe all of Dennis' speakers have the same tonality across the board and I've listened to his original AA Monitors so I've heard with my own ears how he "fixed" those Pioneer BS-22's with a few minor modifications. I have no doubt those BMR's are fine speakers. I'm glad it worked out for you.

Like you, I also auditioned a bunch of speakers and I have to say that I agree with your take on the Sonus Faber Olympica's. They did not have the presentation I was looking for. They seemed thick and syrupy to me. After much listening, I opted for the 805 D's and supplemented them with a REL S/2 sub. That combo had just what I was looking for. That brings me to trombones - the brass on Children of Sanchez (Overture) by Chuck Mangione made me stop and take notice with this set-up. I mean Wow! I was struck by how alive, dynamic and realistic the brass sounded. The trombone particularly. The whole song is fantastic for putting a fast speaker through the paces. It has it all, highs, lows, brass, percussion, guitar, etc.

Lesser speakers cannot do this recording justice. Play it, turn up the SPL and enjoy those BMR's!
