Tech That Flopped!

@donvito101 -

You are kidding, right? All sealed cabinet, voice coil speakers fall into the category of "acoustic suspension."

Bass reflex is not always adding distortion.

On extremely large cabinets with specific heavy duty woofers the reflex port can be used not to extend LF response but to enhance linearity and increase SPL capability.

It is true that the majority of bass reflex is used to make a small box sound bigger and this is a pursuit of quantity at the expense of quality

BR vs. AS is a debate that will never die.

All of my current speakers are BR, but I’m not religious about it.

I can say most definitely that these two technologies are among the most accepted ways to make a loudspeaker for the home, so neither fits the category of a flop.

The confusion comes from the older generic bass reflex enclosures that extended LF by adding almost random bass emphases at varying frequencies.  I had a few of these.

Change came from the application of filter theory as exemplified by Olsen, Beranek,Theile, Small and others so that tuned vented enclosures can offer controlled performance.

Semantics, I guess.
