Announcing a New Affordable Accuracy Quick Kit

A major increase in the price of the Morel tweeter forced us to discontinue our popular Affordable Accuracy "Plus" kit, but a replacement is ready for purchase that looks identical and sounds virtually the same.  The new AA kit uses the Parts Express version of the Morel tweeter, along with the same 6.5 inch woofer from the Plus version and a precisely engineered 14-element crossover that optimizes the response of the new tweeter.  Pricing is only $325/pair plus $22 flat rate shipping.

Like the Plus kit, the replacement AA is literally a snap to build.  All you have to do is snap on the crossover wires to the input terminal, woofer and tweeter, and screw in the drivers.  The cabinet is completely finished and the crossover board is factory-wired and ready to install.  There's no soldering and no sawdust.

Unlike other speakers in or even substantially above the AA price class, the AA provides useful bass response down to 38 Hz.  For most music you won't need the complexity or cost of a subwoofer.  The new crossover carefully controls off-axis response to avoid any peaks without the need for a tweeter wave guide that can restrict dispersion and introduce colorations.  The AA will easily stand comparison with other popular monitors from Revel, Elac, and SVS selling for as much as $1,100.

The New BMR Tower

Although our BMR monitor provides exemplary bass extension down to 34 Hz, true full range performance requires a larger cabinet and a larger woofer.  Working with Paul Kittinger, who is an expert in transmission line design, we have developed a mass-loaded transmission line cabinet that utilizes the same 8-inch Scan Speak Revelator woofer that performed so well in the Philharmonic Model 3.  In our opinion, the Revelator woofer is the finest available in this size class and provides flat in-room response to 25 Hz with absolutely no port noise.  Useful response extends to 20 Hz, which you can test for yourself using our new demonstration CD.  Detailed specifications for the Revelator woofer are here.

In addition, the use of two BMR midrange units in an MTM configuration further improves power handling and provides increased clarity in the lower treble and upper midrange.  We recently demonstrated the BMR Tower at the Capital Audiofest in Washington, D.C.  The Absolute Sound magazine named the Towers "Best Bargain" at the show and had this to say about their performance and aesthetics,

The speakers fared extremely well on both large-scale orchestral and chamber music.  On the basis of sonics alone, the speakers are a bargain; add in the exquisite carpentry and finish and they become an incredible bargain.

A full review of the BMR Tower with extensive measurements can be found here.  The Audioholics reviewer sums up his impressions as follows:

With an almost totally neutral response out to such a wide angle, those who want accurate sound reproduction do receive it in these speakers.  They add nothing nor do they subtract anything from what is in the original recording ... the BMR Towers could easily be used as studio monitors for any sound engineer who wants to know the truth of their recording.

All of the towers are priced at $3,700/pair, plus shipping.  To order, just email Dennis at

The BMR Monitor

These speakers are awesome.  The tonality revealed things in songs I’d never heard before. ... The resolution reveals little details such as slight inflections in voices and even accentuates the breathing-in of a vocalist before they begin their next line.  It was a new experience for me to hear these kind of details.  The soundstage is incredibly large and well balanced and the reflections in the room help to extend the soundstage to a size I’ve yet to hear from another speaker to date.

There are many choices for high quality bookshelf speakers at less than $2,000 a pair.  These offerings tend to be smaller 2-way designs with limited bass reach and restricted horizontal dispersion.  What has been missing is a 3-way design with deep bass response and drivers that offer true 180-degree frontal radiation.  Our BMR Monitor fills that void.  The RAAL true ribbon tweeter provides unparalleled horizontal dispersion and ruler flat response up to frequencies far above human hearing.  The unique Balanced Mode Radiator midrange matches the broad dispersion of the RAAL tweeter, thanks to a shift from pistonic to a bending motion well below the crossover point.  Finally, the ceramic SB Acoustics 6-inch woofer delivers a rare combination of deep bass extension and linear frequency response at higher frequencies.  Useful bass response extends to 34 Hz, and the smooth upper end allows a second-order acoustic crossover that boosts sensitivity more than 2 dB over the previous BMR model.  All of the rectangular BMR's are priced at $1,700/pair, plus shipping, and come in either piano black or rosewood cabinets.  The curved rosewood or walnut burl versions are $1,900/pair plus shipping.  All BMR cabinets are furniture quality and come with magnetic grills.  The next available shipment of BMR's will arrive in April.  To be placed on the wait list for the April BMR's, just email Dennis Murphy.  No deposit is required.

Other BMR Purchase Options

A finished version in a wide variety of veneers and finishes is available through Salk Sound for $2,395/pr - $2,595/pr, depending on finish.  You can also build your own BMR's at lower cost by purchasing a kit version from Meniscus Audio.  The Meniscus kit includes all of the crossover parts, hardware, drivers, and plans for about $940/pr.  Meniscus will also assemble and wire the crossovers for $105/pr.  If you don't wish to build your own cabinets from scratch, Leland Crooks at Speaker Hardware will provide Baltic Birch flat packs for $149 - $169 a side depending on the quality of the birch veneer.
