Post Subject: TAD time alignment and Too much choice with YamamotoPosted by enjoy_the_music on: 12/6/2007
Hi
Well I am fairly new to active speakers. I've been in contact with Merlin and Guy in the UK about these type of speakers and their experiences. I'm just taking it all in and then going forward making a few mistakes and then learning about them! I added the 703's and have yet to time align them. The benefits, time aligned or not, are clear.
I did print out a large grid with lines of 1mm spacing and varying angles. I then moved the tweeters back and forth and played around. In essence I could hear little difference between the majority of positions. I still think I will eventually get things done properly although I have only recently (last week) plugged everything together with the crossover.
In the end I just opted to perch them on the centre of the horn. I hear little comb filtering or blurring of vocals. The most important thing was to make sure they were equidistant and setup correctly. The experiments will continue..
Also a few people have suggested perhaps the bass also needs to be delayed/aligned.
There are quite a few variants appearing from Yamamoto now...most notably 101D and 205D. Too much choice for me, difficult with my experience to decide...
Also perhaps I may try another amplifier in the lower frequencies instead of the Berning. Was thinking about some digital monoblocks. Quite strangely (although not a surprise) my cordless phone interferes with the Berning's output. Buzzing noise generally.
You mentioned before that you roll off your bass units on a shallow slope. Do you think that might be possible with the 1601a's?
Regards
Richard
