Yes, I did design mine for proximity to a rear wall. Like most people, I just don't have the space to put my speakers 1 or 2 metres away from a wall.inertial said:Hi David, (sorry for my english)
Very interesting article . The 5 seems to me very impressive.
Why people not clone it? People clone wilson ,avalon,proac,etc.......
About your nice Diy speakers, why a Audio Technology 95cmq with a very big magnet instead a good 45cmq like Mr. Vandersteen ?
If I well understood , your speakers is placed "to the wall" (half-space).
Am I right?
superiority of passive over active crossovers, and dealing with rear-wave energy.
In this case, "natural" refers to how accurately the driver or drivers under test reproduced sounds and music we recorded. Besides musical instruments and voice, we would record things like a shovel scraping on concrete or shaking car keys. We’d then use the same shovel on the same bit of concrete in the test area, live, to compare how drivers (and crossovers) sounded playing the recordings of the same sounds. It was really helpful to be able to duplicate these recorded sounds live right in the same space where the drivers and crossovers were being tested
Even the wire connecting the driver to the crossover is part of this entity and has to be accounted for in the design. You can actually surpass what you can do with biamplifying and an outboard electronic crossover.

ruerose said:The article is from 98, and since then IMO a LOT has changed in the active crossover realm. Back in 98, there was no DEQ2496, 24 bit was a studio-only proposition, and there was no consumer-priced active XOver modules out there. Computer modeling has grown in the DIY and even using active crossovers in HT and Home stereo is not as niche as it once was (though it still is to restricted to mainly DIY)
An article from 98 is sure to be a out of date with the current state of affairs. But besides from having vested interest in a speaker company, he does means well and I agree with most of his opinions.
