In Reply to: You forget the response in the mids..... posted by Belgarchi on July 11, 2012 at 09:58:04:
Legitimately, the 8530 has an Fs that is closer to 45hz than 30hz. It's response drops off significantly below 60hz in most alignments. So realistically, it's good for about 5 octaves. Six octaves would mean a crossover around 3800 hz which is too high for a 5 inch midwoofer as off axis response drops off sharply due to combing effects. Similarly, use of large drivers (12- 15 inch) has serious drawbacks when implemented in two ways and crossed over from 1500 hz up. Wide variations in off axis response when transitioning from an oversized driver to a tweeter (whether a five inch crossed at 3.8khz or a 15 inch crossed at 1.5khz) kills imaging performance. A smooth transition is required from one driver to the next to achieve a well balanced, high fidelity end result. The Scan Speak 15W8530 is still an excellent driver with a good, usable, 5 octave bandwidth. But it is not the best thing since sliced bread as the OP seems to suggest. Like anything else, it has its strengths and limitations. It's primary limitation is pretty well acknowledged by the company that makes it. It's advertised as a MIDWOOFER - not a woofer, not a tweeter, and not a full range.

The old Dynaudio 15W-75 and 17W were known to do some of the best mid-bass in a dynamic driver - cfb 06:11:53 07/10/12 ( 0)
