The 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 demonstration tracks. 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. The Absolute Sound magazine named the Towers "Best Bargain" at the 2021 Capital Audiofest and had this to say about their performance and aesthetics,
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.
