Impressive. Whats the purpose of the complicated shape between the mid/tweeter box and the woofer box?
Concentric speaker with Eminence Beta10CX and ASD1001
hi all,
here are the images of my first speaker, It's a concentric design based on Eminence Beta10CX and ASD1001. 65 liters volume tuned at 42 Hz.
The crossover is a slightly modified version of the eminence PXB2:2k5 CX.

Congratulations on your first build.
When you would be feeling the need for improvement, consider PMC-like TL enclosure and autoformer (instead of resistive, as it seems to be now) attenuation for the tweeter. 😉
I predict faster, more dynamic and tighter sound plus cleaner HF. 😎
Best wishes,

Google is your friend. 😉 (not really)
There are speciallity solutions out there, for example:
Autotransformers | Critesspeakers.com
...and others, but I explored the PRO market attenuator and it worked for me. It sounds better than resistor.
There are some clips on youtube also comparing several options, even with Duelund resistors 😱.
Cheers,
M.

Full Range sub-forum is for speaker that uses only one driver to cover the full range. I.e. a 1-way speaker.
But it's an unstructured and misleading name...

The frequency sweep looks excellent. You must have designed it well. How did you make your design choices?
I saw your design rationale on your sub thread:
My philosophy is lot of membrane areas and low stroke. It produces little distortion.
I think it is important with low group delay.
The room is also very important, and it is important to work for short reverberation in the lowest bass
Can I ask about the "6 pcs. Acoustic Elegance TD15M in OB - midbass from 60 - 500 Hz" please?
Is OB short for open baffle?
Were the TD15M originally meant for a sealed box?
Did you put the TD15M in a sealed box?
If so why change and how does it sound?
Thanks for posting your photos and measurements of your super system!
