    Just wondering about any impact from the PVC enclosure.. I have made 3-way speakers with cardboard tubes and always wondered about PVC since it is more common. I think the tubular design is elegant even though very few people choose to use it.

      Sorry for the delayed response, been a little busy with the holidays. The PVC has worked out extremely well, the rigidity from being circular and also the thick wall make a perfect enclosure. Also the bass is actually more than I expected,so much so that I had to fill the inside with polly fill to dampen it. If I had to it over and build a set for somebody else I would probably make it completely sealed just to lessen the bass a little.
