So what makes Gaia a milestone in audio loudspeaker technology?
Quote from: Snickers-is on 19 May 2007, 08:15 pmSo what makes Gaia a milestone in audio loudspeaker technology?I don't mean to sound negative, but generally it's poor form to start making these kind of claims before you've actually built the speaker and listened to it.Your ideas are interesting though.
Why did you choose to use an WMTMW configuration with the waveguides? The waveguides push the acoustic centers so far apart that you're going to get severe vertical combing. It seems you've prioritized smooth horizontal dispersion at the expense of extremely poor vertical dispersion. Wouldn't a regular WMT configuration with the waveguides better meet your goals? Do you have any simulations of the vertical dispersion that you can post?
You wrote: "They also conclusively end up with one other parameter that totally knocks out harmonic distortion, phase response, group delay, timing issues, impulse response and so on. This is the dispersion pattern, or energy response as I like to name it."I agree very much with that statement. Again and again, differences I hear between loudspeakers can be traced to their radiation pattern characteristics. You Norsemen seem to have a better grasp of this than the rest of us - Gradient, Amphion, Genelec, and now Midgard are all companies that pay a great deal of attention to radiation patterns (some more than others). Any theories as to why that is? Maybe you have to spend more time indoors due to the cold, and so you spend more time listening to music and making observations about what sounds right and what doesn't? Or, could it be a Viking thing - an affinity for the role reverberant energy plays in a large hall?
By the way, your English is excellent - you don't even write with an accent!
Your shallow waveguides look to me like they would give an unusually wide radiation pattern. Can you tell me what the pattern is? Are they constant-directivity devices?
You mentioned adjusting the phase and even delay of your multiple woofers. What sort or pattern do you end up with in the bass region - a dipole, a cardioid, or something else?
Overall, it looks to me like you thought about how an ideal loudspeaker would interact with its environment, and then set out to create a speaker that would embody that vision. My hat is off to you on your innovative approach. Very best of luck to you and your company.Duke
