Kenny...You took a cheap shot at me,totally uncool.I apologized for my phone and its ability to change words.I agree that its how a speaker performs in ones own room,and yes Ive never heard this line of speakers.Call that a disqualifier if you will.The original poster has a legit argument and I thought it was well conveyed,certainly not a waste of time.Having said that from what Ive read(not on this site obviously) that a few things speak loudly..the Double impact fell on its face at the LA show according to most,it has cheap tweeters and drivers,the cabinet is cheap and its visual look is one of a DIY,they have no retail outlets for consumers to audition,they have no customer support really outside if you don't like them send them back,most that have reviewed them say they are good speakers "for the money"but certainly not 30K busters...so I guess im not drinking the Kenny kool aid right now
Tekton Double Impact & Comb Filtering
Like many of you, I have been pondering purchasing these speakers but am very curious about the unusual tweeter array. I asked the smartest speaker person that I know (he is a student of Sean Olive) about the design and below is what he had to say.
"In theory it could work, but the driver spacing means that the crossover point would need to be very low.
He is using the SB acoustics tweeter which is 72mm in diameter, center to center on the outside opposing drivers is around 5.7 inches, which is about 2400Hz. This means that combing would stop between 1/4 to 1/2 of the wavelength (between 1200-600Hz) is where the outside tweeters should start playing nice with each other.
Since he is not using low enough crossover points he has created a comb filtering monster. Now while it's not the great point source that was promised, it's no worse than most line arrays and the combing will average itself out given enough listening distance.
The MTM spacing on the other hand is ridiculous. Hopefully he is cutting the top end off on one of those midrange drivers to avoid combing."
