Not sure on that one. IMO: I have never liked bandpass boxes. In theory, they are cool. In reality, I can smoke one with a nicely tuned ported/vented enclosure. I have worked with many pre-fab bandpass boxes over the last 15 years now and I will tell you this, as probably most pro-boxbuilders would: if you want a bandpass box to REALLY work for your speaker, you have to build it from scratch. pre-fab bandpass boxes are generic moulds and not designed specifically to enhance the output of a certain speaker. Speaking from experience, it takes a lot of math and time to build a true 4th or 6th order bandpass box. The ending result however, as I stated earlier, still won't stand up to a properly tuned vented enclosure.

Anyone ever build a transmission line box?

this q-logic box comes with inner rubber flanges to tune the box but maybe my skills lack and thats why the port vents rattle posted_image

TLs work great if you have the room for them. FAR better than any BP enclosure with much higher SQ. I built TL enclosures for my home. Let us know how you like it, skold.

Whats the best bandpass box? A busted one in my opinion. Never have like bandpass. If the plexilook is what you after, why not build a sealed enclosure with a glass window in the back?
