Kenjit: "That sounds like what you’re doing Audiokinesis. You accuse me of dishonesty and question my motives all the while avoiding addressing any of the criticsms I’ve made to justify my belief that the product is flawed."
So now you accuse me of doing what you did (avoiding questions) when you NEVER directed a question at me until just now? Kinda hypocritical, don’t you think?
I expect you to answer my questions about your room and amp in exchange for my responding to your criticisms.
Quoting kenjit again:
"1. Wrong box / woofer combination
2. The tweeter used in mine were not impedance corrected and not rolling off sufficiently.
3. Crossover was not optimized"
Here are my responses:
1. All box/woofer combinations involve tradeoffs. You may disagree with Roy’s choice of tradeoffs, but that does not make them “wrong”. A bigger box might go lower at the expensive of pitch definition. A different woofer might have more bass but not meet the requirements for a time-coherent two-way speaker. Did you try positioning the speakers to take full advantage of boundary reinforcement? The speaker/room interaction dominates the bottom few octaves.
2. A tweeter does not necessarily need to be impedance corrected; competent designers aren’t limited to cookbook approaches. And a first-order filter (essential for a time-coherent design) inherently has a gentle rolloff slope, so you have confirmed that Roy was doing that right. Some tweeters can handle it and some cannot, it all depends on the specifics, but Roy is plenty smart enough to choose one that can. I bet you could too if you had the right test equipment and used it properly.
3. How in the world do you know that the crossover is not optimized? Have you seen the measurements? Were you there when Roy presumably said, “It’s been a long day, I’m not going to optimize this crossover”? What in the world basis do you have for making this kind of statement? You don’t like the speaker, that’s one thing, but don’t start making things up. There’s a word for that. And aside from an incredible stroke of good luck, it is impossible to even approach time coherence without a LOT of optimization.
Now it’s your turn. Show us that you’re not a hypocrite. Tell us about your room and your amp.
