I've been bored lately and this came to mind. It has probably been hashed out here before, but I'd like to keep the same thread reoccurances like the RTi's vs LSi's have going :D
Could an on wall SDA speaker be made? With all of the wall mounted televisions, many companies are going to speakers that complement them. The SDA ones would not necessarily be for use with a flat panel tv, but I guess they could.
The enclosure could be somewhere between 15"-21" wide and maybe 3"-4" deep. Height could be varied, depending on the numbe of SDA drivers you wanted. They could be ported at the top, sides, or bottoms, or a passive radiator could be used.
I wouldn't expect the same type of bass response for these speakers, since they could not have the same internal dimensions. They could be mated with an appropriate subwoofer, in-wall or freestanding, to supplement the lower frequencies.
This design would be more WAF friendly and still allow us to have our SDA's. I know my wife has cringed every time I show her pictures.
I'm working on a couple of quick sketches(nothing elaborate). I'll post them when I get a chance.
