Ahh Dave so your design is finally done Hope to hear them sometime since I am familiar with that reference speaker you mention
If you're in the area feel free to stop by! I still love the Pioneers and they really are the last word... well, besides the reference series... in upper midrange and treble detail and clarity. Hard to beat a vapor-deposited beryllium tweeter custom made by TAD. But I think I've come close, the Fostex T500A MkII super tweeter turned out to be a seamless match tonally with my midrange driver, and this really made the high end come together for me. I have the Pioneer's bass beat by a mile, half the distortion or so... and max SPLs are much higher too
But the key really is the close approximation of a point source horn speaker, it has a presentation that's very different from a regular speaker.
Jesus Christ... do you have an hearing aid plan to go with them?
Lol, gotta use some discretion! They play clean though, and way past 120 dB if you want them to. I think distortion at high volumes is really the problem with hearing damage, but yeah, high volumes are fun but should only be done in short intervals. It's nice to crank a favorite track to concert levels every now and then, especially when it's a live recording and you can achieve the same SPLs.
The woofers are 15" with 19mm xmax so they are just loafing along most of the time. They do drums really well, which was one of the main goals... gotta have that impact!
