My little toy

Impressive. Whats the purpose of the complicated shape between the mid/tweeter box and the woofer box?

Great could you share some details?

Is that JBL D130? If yes, thunk the Vb is too small. It feels very good in 5-8cuft. The bigger the bettet. But its a fantastic extended range driver.

No, K140.

Nice! Love those bevels on the separator. Nice touch.

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,
M.

And where do you usually shop autotransformers?

And where do you usually shop autotransformers?

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.

Can anyone with authority move this thread to the right Place. Multi-Way?

 

[TNT]

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...

Saw it, but a little late

 

[Cal Weldon]

This is ripe for the system pictures and description area so I will move it there.

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!
