HiWave BMR12 Compact 2" Full-Range Square Speaker 12W 8 Ohm

We've purchased a truckload of this 2" HiWave BMR (Balanced Mode Radiator) and are passing the savings on to you!

HiWave BMR Series are the first full-range, off-the-shelf drive units using HiWave's patented BMR technology. Square BMR12 2" drivers combine the qualities of HiWave's flat panel speakers and the pistonic movement of conventional speakers. The technology's wide directivity enables flexible placement options, while the wide frequency response means BMR drivers can also deliver cost savings to engineers, since no crossover components or frequency-specific drivers are required. Excellent for line arrays or most any other type of sound project where space is limited and sound performance can't be sacrificed!

The BMR12 2" drive unit has an excellent and extended frequency response with wide directivity and is ideally suited to compact full-range applications that require a high performance acoustic solution. Typical examples include MP3 player docking stations, Internet/DAB (Digital Audio Broadcasting) tabletop radios, and home theater speaker bars. Hurry, limited quantities!

HiWave BMR12 Compact 2" Full-Range Square Speaker 12W 8 Ohm
HiWave BMR12 Compact 2" Full-Range Square Speaker 12W 8 Ohm is rated 4.4643 out of 5 by 28.
Rated 5 out of 5 by from awesome speakersUsedd four of these along with some soft dome tweeters installed in a cigar box looks good and sound great

Rated 5 out of 5 by from perfect box if you have wood skillsNeed a great box. Find some AZEK scraps from a construction job. it is 3/4 inch thick. cut them to three 3.5 or 4 inch squares. Take three, clean them and epoxy them together with a big clamp. this gives you a sort of cube. drill thru the solid face with a 2 1/8 inch forstner bit leaving 1/4 inch solid at the bottom. this gives you an ideal rigid cavity and max bass. after drilling, I use 2 inch SPAX screws on each corner (half way between the outside and the hole) thru the 3 layers for security. After i am done machining, I take the entire thing to my miter saw and cut the 4 side edges smooth and even. Then you can no longer see that it is 3 pieces. bring the wire thru the 1/4 inch remaining and seal it. You can stack these if you cut them the same size. AZEK is a rigid poly foam board used for construction. It is water proof and very sonically rigid. It is easy to cut and drill and after priming can be spray painted. It is easy to cut and will not split when screws are driven in. You can try 4 layers. the bass gets a hair better but you must use DSP compress the bass below 150 or the coil could be damaged with heat or over reach.

Rated 3 out of 5 by from 100Hz, 'bout as low as it goes realistically.I would use these for a BoomBox if smallest size is your main goal. Just realize that you can't even hardly hear 100Hz or below with these. They've got decent volume though. The highs are nicely crisp if you're playing back from hi bit-rate encodings. The mids are sharp too. I'm thinking I will use them for a BoomBox intended for Beach duties so I'm not worried about it getting damaged due to the low cost.

Rated 4 out of 5 by from The "Lil Buggers"!!!I had been intrigued by these for a while and added 4 of them to make free freight on an order. I was originally planning to make a self powered mp3/ Blue Tooth mini player with a Tang band mini sub. In the mean time I decided to have a little fun with them. I was reading DJBOUNCE_1 on the reviews and went to my local Dollar Tree and found 2 different mini spice containers that fit his description for enclosures. Being that I had "bigger" plans for these drivers I hot melt glued the containers to the BMR12's rather than epoxy, so I could take them apart and with wiring coming out thru drilled holes in the back that were also hot melt sealed. I hooked them up to my Carver M4.0T Silver Seven amp (WAY overkill but why not!!) put em on top of my vintage Polk LS90's and listened. I was really impressed but couldn't tell the sonic difference between the 2 different enclosures. I decided to parallel them together for a 4 ohm load and tightly wrapped each “enclosure” with vinyl electrical tape to (theoretically at least!!) damp any resonances from the thin plastic mini enclosures. Then I taped them together with vinyl stubs in between to make mini columns. No real bass of course but nice dispersion and imaging that filled my living room! Then hooked them up to a DTA-1 and a Zendac sub-woofer (PE buyout from years ago!) that I run in my bedroom and after some tweaking on the sub they blew me away!!! I said to myself, "these Lil Buggers sound good!" Hence the name. Next day I took them to my local pub, set them up on the pool table with the DTA-1 & my Crackberry and played played some tunes for my buddies. They couldn't believe the music coming out! Just goes to show that some times we don't have to pay so much attention to TS parameters, resonant frequencies and enclosure volumes! Just experiment, play around and have some fun!!!

Can these little guys survive in an automotive environment, excluding the dash and the rear deck? I was looking to add them to the hefty B pillar in a Lincoln Mark & coupe ,2 speakers to each side .

Asked by: MarkL7
Yes these are made of materials that will hold up fine in an automotive application.

Should I add a tweeter if using these in a 16 per side line array? I intend on building a pair of 16 driver line arrays like mentioned above in the reviews. If I do add a tweeter, where should it go? In the middle a la MTM? Along side? Crossover point

Asked by: chris45
Adding a tweeter is very subjective. These are small enough to be full range although off axis the high frequencies will droop. I usually recommend hooking them up full range first, then you can always add a tweeter later if you feel like they need more top end.

Looking to use 18 of these (to achieve 4ohm) in an edge-to-edge linear array as the center channel for my home theater.  Planning to mount the array vertically (as recommended) and behind the acoustically transparent screen. Any words of advice/caution?

Asked by: SoundInNC
I don't find anything wrong with the theory although you will not achieve a proper 4 ohm load with 18 drivers. 4 drivers will bring you back to 8 ohms, 8 drivers will drop it to 4 ohms and 16 drivers will bring it back to 8 ohms. I would recommend either 8 or 16 drivers for an application like this if you need an overall load of 4 ohms or higher.

What would happen if I used this speaker, with no filter, as the back speakers in a surround system? The amp is rated at 100 watts, but I never turn it up very loud at all.

Asked by: jcsh
Generally the surrounds will not produce much bass. If you are playing them full range you may have a problem with some movie passages, especially since these are so small and inefficient meaning they will have to be turned up quite a bit to hear them. i would recommend a high pass filter on the receiver set no lower than 100 Hz.

I am building 2 bookshelf speakers w/ 4 of these in each, wired series/parallel. I have 200uf non-polarized capacitors to add to each driver. Where do I add them?

Asked by: Wiltzor
With the drivers wired in series/parallel, the easiest way to do this is simply to put one capacitor in line with all four, series to the positive input.

Can I wire 5 of these in series/parallel to maintain 8ohm impedance?

Asked by: Wiltzor
Unfortunately no, the only way to maintain an 8 ohm impedance is to use four. You would have to wire them all in series in order to use 5 which will yield a 40 ohm load.
