Hey All,
Just got a pair of Heresy IIs and I'm already looking for ways to tweak 'em. Currently driving them with Quicksilver 8417 mono amps, Sonic Frontiers SFL-1 preamp, and HK 8550 cd changer. The setup works pretty nicely, but a touch too bright and sibilant. I'd like to wring some of the bugs out.
First off, what is the recommended positioning for these speakers. I've started with them about 8 feet apart, against the back wall and toed in. Any hints?
For example, I looked at the crossover and it looks like four blue film (?) capacitors, an electrolytic, a ferrite bobbin coil and an air-core coil. The coils both look pretty anemic. An upgraded crossover seems mandatory, but does anyone have a schematic?
How about damping the horns? Saw something about damping with modeling clay, but not sure what the specific sonic results are. Also, in mine, there is a single piece of acoustic foam in an upside-down u-shape behind the woofer. Would lining the inside of the cabinet with deflex or fiberglass help?
I have some long-term ideas bouncing around in my head too. For example, why not make a separate cabinet for the woofer and mount the horns on an open baffle on top?
Thanks in advance,
Jeff Englert
