Well so far they are working out better than I expected. Bass response is surprisingly good but still needs a subwoofer. The port is about 1" longer than optimum as it's less than a full diameter away from the back of the enclosure. But I think it will be fine since I don't intend on driving these to their limit. I wanted clear dialog for movies and good music performance and, above all matching vertical L-C-R speakers in a clean install. I used the in wall cross overs which I think are supposed to be for an infinite baffle I.e. a wall cavity but I installed them in sealed, matched enclosures. Whether the x-over was used with an IB or ported enclosure it's main advantage is no baffle step compensation. On Madisound's website, there are 2 different port flares associated with these speakers. The one I got was shorter than I planned on but actually worked out better with my shallow enclosure because it was shorter. Madisound was very helpful and I want to thank them for putting up with my frequent panicked phone calls. These were the first speakers I ever built and I wonder if I could have screwed up to the point that I wouldn't have been happy or, if it's just easy to achieve good results with a little research and planning? Don't know. I'll use them for a while, build a subwoofer fine tune my setup and just be happy with it.
