How's the move coming along? Have you had the chance to experiment with sub location? I'm really curious about having equal subs centered in the front and rear (the Harman alignment). If you've tried it, how does it sound?
I exchanged e-mails with the author of that paper and he said the front sub should be in phase with the mains, and that the rear sub's phase should be set so it fires at exactly the same time as the front suib (no delay). To me, what that means is the only way the front and rear subs would be "in phase" is if the seated position was exactly half way between the two subs. It seems kind of weird, but he wrote the paper. He also said the out of phase nature of not sitting in the middle is what allows the rear sub to fill in the valleys and drop down the peak in the in room frequency plot. Lastly, he said the central location (right to left) should minimize any localisation that occurs. But, a lot of that is theory... I've been told by someone else who's tried the two sub Harman alignment that localisation of the rear sub occurs above 50 Hz (probably due to proximity). Please comment! Thanks  . |
I just completed the move but I'm still a ways away from the set-up. I need to do some acoustic treatment first. I've read a few articles on dual sub placement and I'll likely go with the left and right locations (mid way in the room against the side walls). I'm not sure how phasing would work for that positioning though. Let me know if you have any thoughts on the phasing.
Thanks,
