Is this a TL/MLTL?

Tuliman · 14th April 2006, 07:10 PM

I am curious about this, is that BR, TL...?
It's using a 6-3/4" driver, with a Fs of 38.

Unless my eyes are fooling me that looks like a simple BR with a slot port.

A BR? I thought it was a MLTL... whats the proper distinguising feature again?

Cal Weldon · 14th April 2006, 09:10 PM

On second thought, maybe that is an MLTL. I might have done my homework before answering.

I'd say its a slot loaded BR.

It could also be a MLTL or QWTL it just depends how the box dimensions relate to the drivers T/S parameters I think.

Take a BR with roughly equal LWH. Start increasing the height while keeping the volume the same. Keep the port at the bottom. As the box gets taller, the design will transition from a bass reflex into an ML-TL as the quarter-wave resonance starts to go lower & lower.

The aspect of this design is such that it is closer to an ML-TL than a BR.
