Earlier I posted this query in the Chane website forum but now think that I may get more thoughts here: I'm thinking that I should get surround side/rear/height speakers that have high output capability (I already have Chane A1s for side/rear surrounds but still need to buy height speakers). Or am I wrong and should go with Jon Lane's (Chane) decision of designing a surround speaker with limited output? Jon wrote this concerning a new Chane surround sound speaker model: -The A4.4 onwall surround/effects speaker we've all wanted. It'll be loosely based on the A1.4 but without the SplitGap tech (don't need it for lighter duty) and in a much smaller cabinet. To me, he is saying that surround sound speakers do not need to have high output capabilities because surround sound audio signals will not call for high output. Yes, in years past the surround effects signals have had limited specs (i.e. limited frequency response, limited output...), but my understanding is that with these new surround sound formats, all limitations have been removed, height speaker signals (ceiling speaker signals) now have full frequency and output range. So in practice if there is a helicopter hovering directly above you, all of that high output sound can be sent to the height speakers. I'm hoping that in the future more and more sound engineers will take advantage of these new surround sound specs.
