Speaker cabinet construction..

Not sure this can truly be considered a white paper as it was originally penned on parchment.

All the VSA speakers are ported, either front or rear, and employ a tunable transmission line woofer cabinet. The speakers can be tuned to the room by adding dacron filling to or subtracting from the port tube. The speaker can effectively become a sealed enclosure by filling the tube totally. This will tighten the bass but will likewise reduce the amount of bass. What you choose to do depends on your room acoustics.

Shadorne,

That's quite a conclusion you've jumped to. Am I sensing a history with VSA? I think it's fair to say that a paper regarding cabinet resonances can be written without the inclusion of porting. That's a different can of worms altogether. Albert Von Schweikert is a very successful speaker designer/manufacturer and I for one thank him for taking the time to explain cabinet resonances in technical terms. Don't be surprised if you see the occasional technical paper from the likes of Dave Wilson or Alon Wolf, "couched as science" or not. Don't forget, these gentlemen must sell what they design and manufacture. If they choose to write a tech paper explaining why their particular design may be better than that of the next guy, then more power to them.

Shadorne,

Being a retired EE and putzing around with this hobby for over 40 years, no one is more skeptical than I am....trust me...so believe me when I tell you that Albert Von Schweikert, the "mad scientist", would NEVER put form above function. All you need to do is look at some of his previous speaker designs....zero WAF. His current designs are aesthetically pleasing to be sure but I wouldn't bet huge sums of money that he had a lot to do with the VSA aesthetics evolution. All the VSA speakers make great music regardless of price point, and tend to outperform speakers costing magnitudes more. That's my story and I'm sticking with it... :-)
