Stuff BR Box FE126e?

[DreadPirate]

I'm doing the BR recommended design, do I stuff with fill, line with insulation, or do nothing?

The hybrid or the BR? We were very dissatisfied with the performance of our build of the hybrid.

The little BR looks to be a non-starter (at least for me) ... sim below

With either of these you are going to be looking for bass support. Once you factor in bass support, you might as well use the FE126 sealed...

If you haven't already cut material for these enclosures, and unless really constrained by space, you might want to reconsider.

I built a pair of these several years ago (for previous FE126E), and as with several of Fostex's "recommended" designs, they were quite underwhelming to say the least. Two public domain designs that I know work very well are the Buschhorn MkI modified to fit larger driver, and the latest generation of Frugel-Horn.



edit:

we don't always finish each others ....

I agree. Thanks for the sim! Lots of better cabs for this driver. I actually like the idea of sealed with bass support.

Good call. Or even a small front horn / waveguide + bass units.

I do have this sub available:

Amazon.com: Sony SA-WM250 100-Watt Active Subwoofer: Electronics

What sized sealed box, same?

I'm just looking for something quick and easy to make to see what FRers are all about. I will go deeper into a horn type build later with this or another pricier driver.

probably anywhere from 8-13 liters would be fine

if new, make sure the drivers have a thorough break-in before finalizing XO settings on the sub and any additional EQ / filtering on the wide-bands


and you don't necessarily need to get spendier than this driver to get musically satisfying results

With an 8" driver the woofer probably goes high enuff. Ideally you would need 2 woofers. A 1.5 litre box for the FE126 gives a butterworth rolloff with a crossover point of 200 Hz.

There's the Voigt pipes, that I'm building.

Nice and small, I heard them at a meet, and it was fantastic.

...but pointless if high-passed as you might as well have a sealed box.
