Sold!

For sale is BMS 4590 2' COAXIAL COMPRESSION DRIVER - we have only one driver left.

• Extended bandwidth (300 - 22000 Hz)
• Point source sound reproduction
• Excellent phase coherence
• With two subsystems in one, each driver covers a smaller frequency range for increased power handling, high dynamics and extremely low distortion
• Perfect time alignment without problems of multi-source interference
• 8 Ohm

The BMS 4599ND dual diaphragm driver incorporates two identical 3.5” concentric annular ring diaphragms, connected to a common 2” throat, providing extremely high acoustical output. The patented design of the BMS 4599ND is a result of extensive dedicated research and development, providing dramatic improvement in efficiency. That's because, as I found looking at the BMS site, while most of the BMS coax compression drivers are with Nd magnets, they do have one that has a ferrite magnet (4590). Comparing photos, it is clear that the Diesis driver is the ferrite BMS coax.

Excellent speaker cab, well made, love everything about it! Be ready to wait as it took over a week for them to send it, but it was brand new (could even smell the new paint still) so when I realized the delay was because they were literally building it, it was forgivable. Awesome cab with great resonance

Cobbler S. - February 20, 2020

The level of communication is among the best I have experienced on a purchase. Cabinet arrived extremely well packaged and was paired with a Celestion Alnico Cream after there were issues sourcing a retail jensen blackbird 100.
The cab sounds great closed, but sounds incredible with one panel off.
The combination performs way better than a lot of other far more expensive options I have demoed.

I can wholeheartedly recommend Ashen for product quality and service.
