This thread concerns the design of a centre channel speaker suitable for use as the dialogue channel in home video (home theatre, AV) and alternative suitable Harbeth speakers.
I'm not sure who has recommended you, but are you absolutely sure that you need a physical centre channel and that you can not generate a centre sonically from your front P3s in 'phantom' mode?...I've been recommended to find a center speaker with matching timbre and characteristics...
...Perhaps I should consider designing a Harbeth centre channel speaker. The starting point would be size and shape; once I have that, I can see what drive units could be fitted...
I think people here would be more concerned how good a centre channel that you make will sound rather than how big it will look! If you think 2 x 5" RADIAL + 1 tweet will work, I'm sure no one will have complains!! (except maybe the price)Following a question here, I'd be very interested to dicusee with you a provisional specification for this centre channel speaker concept.
As I said "I'd really like some guidance from you (all) as to features and most important, cabinet size. In the days of CRT TV, the sets were so big that evan a large centre channel box sitting under the set was dwarfed by the TV. But now, with these skimpy thin TVs I'm not sure how big the centre channel can be, or where it is placed. Under the TV? Standing on what?"
So - over to you. How big, what configuration - I'v very interested to hear your ideas.
