One can only wonder how they might have talked if they'd had an opportunity to hear one that is electronically crossed, with a separate tweeter and woofer section.

There is no wide range speaker that can do much more than 300 to 13,000hz adequately. What if they'd had a chance to hear real bass and real highs rather than just a mid range exposition?

It does go to show how much an array can do even configured with inadequate speakers. Thylantyr has an amazing array where he used 49 cent midranges.

The point of my previous post was that PERHAPS comb filtering in an array of 3 1/2 inch drivers isn't as big a deal as the THEORY would have us believe. If people with good ears (Fred Thompson for one) find that THAT PART of the design seems sound, then that's an interesting development, don't you think? As far as whether the other folks had "ever experienced an array before", what the heck does that matter - good sound is good sound, isn't it?

As to the 3.5 inch arrays and Russel you should go down the cue and read some of the previous discussion on Russel's array, and also some of the obvious lack of connection about the progress in building arrays.

I have no idea what you are trying to say.

Do you actually have an array? Have you actually built one? Or have you just listened to Russel's anemic variation at the show? I've actually spoken to several people who either ignored Jim's advice or who decided not to follow it. I dfidn't take the chance with mine. It does have comb filtering but it out near 17,000hz, which is at the limit of my hearing. The people I've spoken to have talked about the lack of sharpness and other warbly terms for their arrays. Have you actually seen the FR of arrays with bad comb filtering?

Its not theory; its reality.

I've made it clear that you can have a pretty dynamic set of sounding speaker from a 50 speaker 3.5 inch array. I've no doubt that they sound great. Geez!! My own array with the 17- 3.5 inch wide range speakers per channel sounded fabulous. But then I added the 30 Dayton Neo tweeters perr channel, and the high end that I thought sound great with just the 3 inchers suddenly seemed dead without the tweeters, and then I added the two 12 inch DVC 15 mm Xmax woofers and the bass was also fab. And my total system including the electronic crossovers, the pre-amp, and the 3 power amps, and constant Q equalizer, didn't exceed about $1700. No where near 18,000 bucks.

Does anyone know what brand 3.5 inchers he's using for them?
