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."

It always seems like an unfortunate use of this or any other forum when the conversation deteriorates into personal criticisms of other posters. The DIs may be Great speakers to some and not so great to others, We are all going to form our opinions on whatever information we have available or whatever information, or lack thereof, that we choose. Isn't that something we should all expect - certainly the equipment manufacturers we all discuss expect that we will do this? Some people are going to choose vanilla and some are going to choose chocolate- so what? It is a pursuit that I believe we all seek to enjoy and our differences of opinion are, I think, both healthy and help to drive this industry. We can evaluate and follow, or refuse to follow, each other's opinion based on how reliable we think that opinion is - isn't that what we do with all other bodies of knowledge? |
The Tekton Brilliance was reviewed today. Same price as the DI. It's smaller and doesn't play as low, but the price is the same. Why have 2 floor standers at the same price? My guess is that the Brilliance is geared more towards 2 channel in a medium room and the DI is more geared towards larger rooms and home theater. http://www.enjoythemusic.com/magazine/equipment/0817/Tekton_Design_Brilliance_Loudspeaker_Review.htm |
