10 db of bass ?....= 10 hz of bass. Guys ( and gals ). You need to look at some of the pro versions of the Heresy’s..........again, nothing new with the ported design, except for the port itself. R.D. had much to do with the design of the pro models. Amazingly, what needs to be done to the news ones, as well, is a " heavy layer " of Dynamat on all of these horn drivers. Danny Richie, on the mods of the Forte IIIs, did not do justice to the mid horns. A recent Steve G. video, about a fellow modding a Cambridge CXC transport, stated, that with every mod that he did, the Dynamat made the most significant difference, in SQ. Again, I’ve been using Dynamat ( and some roofing repair tape found at Lowes and THD ), for the longest time, on not only horns, speaker frames and cabinets, but on electronics, of every kind. This fellow, also recommends, to put a book on top of the chassis, something I have been advocating, for the longest time. I know, this mod stuff belongs on another thread, but I am bringing it up here, because it is a cheap, but very relevant upgrade. I know of only one person, who applied Dynamat to his horns, who did not find it superior in sq, and I do not, for the life of me, understand why. Enjoy ! MrD.
