I just finished installing my setup with AV3 main, AV3s center and AV1rs rear. I'm not ready to write a review yet and I'm not too good at it either but what I can tell you for sure, think about it twice before building ported AV3s, those transmission lines in the AV3 are incredible. The bass is exactly what I was looking for, no need for a sub with music. Before deciding on building the AV3 I was about to buy the Meadowlark Kestrel2 which are also a transmission line speaker. I don't know what it is, maybe I'm a bit biased or maybe Danny would have a real explanation for it but there is something about the bass from a transmission line that I find different in ported speakers. Bass seem crisper and kind of more defined if that means anything. Anyway, I don't help with your question but I thought I'd mention it since you don't seem to have taken your decision yet on a ported version... Cheers.
