[Bennett Prescott]

Do you see it now? I've just freed you from moderation.

Fixed, thanks! I will try and use my new power responsibly.

good to know that's all it was.

For the DCX464, are there any cross-section cut out pictures, or CAD drawings of internal parts & assembly?

 

[Ro808]

Bad pictures...

There are... though not available to the public domain.

Rumor has it the DCX464 is getting a little brother, with 3" and 2" diaphragms.

An externally hosted image should be here but it was not working when we last tested it.

How low will it go?))

 

[Bennett Prescott]

How low will it go?))

If such a thing were to be considered, how low would be low enough?

For a 3" (midrange dia) one I would say I would be Content if it could be crossed-over between 500 and 600 Hz without breaking a sweat in loud HiFi applications.

I honestly have no idea if that is true (FBT is not my customer), but it is interesting to me that someone who claims to know something so specific about a brand new product would post it publicly. I suppose your ability to get future interesting information from the manufacturer in question isn't important to you. It's a small industry with a long memory.

Well, somebody else posted it on the internet long before Ro808 did... And it's also on the product page.. MYRA 214L - No Line Dettaglio - FBT They just don't mention the exact product, but it's a B&C Coax.. how hard can it be..

Does B&C make another coaxial MF/HF compression driver with 100mm (4”) voice coil MF and 36mm (1.4”) throat, 64mm (2.5”) coil HF?

I think it can't be literally "enough" , but 400 Hz seems good enough.
From open source

At the heart of the 214L line array element is a new coaxial 4-inch voice coil mid-frequency and 2.5-inch voice coil high-frequency driver combination developed in cooperation with B&C, and covering the 400Hz to 20kHz range.

Minimum 700Hz
Preferred 200Hz
Maximum 80Hz

This limitation has existed for some time now (as I see it).

 

[cowanaudio]

Minimum 700Hz
Preferred 200Hz
Maximum 80Hz

This limitation has existed for some time now (as I see it).

It is problematic driving a constant directivity horn this low from its apex. Horns that will load a compression driver down to 200Hz will beam terribly at high frequencies.

 

[AllenB]

Perhaps, if you use conventional horn types for something they weren't intended. This needs to be outside the box.

who is expected to review this? audioX didnt do it in the August mag.

Does anyone know of upcoming reviews? and/or comparisons with 4594?

thanks

You should see it in Voice Coil in the fall, not sure which issue but the measurements were just finished.
