The Mission 710s with upgraded woofers from a pair of 770 Freedoms sounded good, but their incredible lack of efficiency has been a concern for me. I mean really inefficient: a satisfying volume is achieved in my place with most speakers at around none or ten o'clock. The 710s produce the same volume at one! While the midrange balance and the good results with sax and vocals told me that the new woofers were compatible with the crossovers, I began to think that this woofer would be better in a ported enclosure, like where it came from and was designed for (the 710s are a rare sealed Mission design).
I mentioned a trade about a month ago, and that one of the pairs had arrived DOA. I was wrong, the drivers had been removed for testing and not reconnected. The speakers are from Paisley Research, a canadian manufacturer that I hope to be able to tell you more about. The model is not indicated. They are very large ported eight inch two way systems utilizing french Polydax drivers, as do the canadian Rega speakers I have loved. The woofers have rubber surrounds and one is perfect, one was torn in many places and needs replacement. The cone diameter is unusual, and a standard eight inch foam was not wide enough. I tried modifying a ten inch surround and couldn't make it work without distorting, no matter how I cut it.
