LA 16 unfinished
If you liked the Naim with 1 BMR, you will love these...16 BMR ( 4.5 inch Neo magnet) per side!
112mm square driver chassis mounted tight edge to edge so 112mm centre to centre. I simply can not hear any peaks / nulls comb filtering effects at any realistic listening distance. even at 1 meter they blend better than a two way stand mount, at 2 or 3 meters they just engulf you in sound.
You are right about imaging, really even everywhere in the room.
Makes Eq'ing easy as it sounds the same off axis as it does in the listening seat.
About a year ago I made an 8 driver per side version using a slightly differend BMR, still great results even with 200mm centre to centre spacing.

4.5 inch Neo BMR
I had to buy a large MOQ of drivers to get the spec and quality I wanted.
The ferrite magnet versions sound muddy and distorted to my ears, the rear wave bounces off the large magnet and straight back through the cone...Out of phase, yugh!
Also the small Sd of the 2 and 3 inch drivers means they have to really pump in and out big time to produce high SPL's. This also adds to the muddy sound and loss of detail, all very stressed.
So for me the 4.5 inch ( Sd 60) Neo magnet is the Goldielocks driver.
I am going to make a range of DIY kits available in a couple of months.
The attached LA 16 's are astonishing, really surprising everyone so far, even me!!

Thanks for the info. This looks a good way to go. Will you be offering the drivers alone?
Neat enclosure design, btw.
And I entirely agree about your comment elsewhere that headroom is a necessary step to getting realistic sound. The last two years I've been using a commercial active speaker which can hit 110dB without effort and makes concert recordings much, much more natural to listen to.

BMR Line Array Kits & Drivers
Yes I will offer both complete kits and raw driver packages.
I have posted driver prices on another thread as well, here they are again:
1 to 9 - £ 49 each
10 to 19 - £ 45 each
20 to 49 - £ 39 each
50 plus - £ 35 each.
For the LA 16 ( picture attached) a set of 32 drivers will cost £ 1,248
The LA 9 ( 18 drivers) will cost £810, and the 8 drivers for the LA 4 will cost £ 392.
I havn't worked out all the kit options and prices yet, but they will be very high quality with everything included for a really high end result.
The finishing will be up to the customer.
The 4 Ohm, LA 16 is a genuine 100dB for 1 watt @ 1 meter:
So 2 watts gives 103dB,
4 watts gives 106dB,
8 watts gives 109dB,
16 watts gives 112dB
32 watts gives 115dB
64 watts gives 118dB
and 128 watts gives 121dB.
I am able to run a very high current and high power, (140watt into 8 Ohms, 280 watts into 4 Ohms) almost flat out with a lot of music.
Realistic in room peaks of 120dB with average 90 dB SPL, actually sound sooooo much quieter than the meter suggests.
The most common reaction and comment is " I had no idea it was that loud until we tried to talk!"
All the best
