Post Subject: Can such steep slopes work...Posted by speedysteve on: 8/8/2013

The systems I've heard with steep slopes (only 4th or 8th order) sound hard and unnatural to me. Admittedly these are on everymans drivers - the sort of thing we all can buy and deploy.Several digital X/O users I've talked too all seem to gravitate to 4th order for all. I've tried this on my system and it just does not sound as good to me as selected slopes sympathetic to the driver and and horn application and room too.I have found 4th order to be the order of the day, for the deep bass channel. 2nd order for mid bass and 1st order for upper side of the mid. 1st order for upper mid and tweeter. The latter two with no upper slope at all, just playing open - less is more.I moved from 2nd order on the upper mid to 1st order on getting the S2's and experimenting with them and reading Romy's own very informative texts on the S2 and 3uF cap listening tests and measurements.I don't recall the exact quote but something like - a really good driver is doing things far down the SPL scale that a poor one could only dream of...
I'd love to hear 120dB/oct system just to know what it sounds like - with the right implementation and due care to everything I could envisage it working from a physics pov, but in the real world?
