My heresys have the e2 xover with k52 mids. I like the way it sounds most of the time, but there are times when I wish they had a little more body or shall we say, "warmth" in the mids. I have an SVS 20-39 sub and my source is either an NAD C542 CD player, or an old NIKKO NT-700 tuner. Amplifier is NAD C320bee. I also sometimes run them with Trends TA 10.1. In an earlier post I have asked about the purpose of the 33 uf cap across woofer, and got no replies. I realize that these speakers were not designed as stand-alone units, but as loudspeakers that were to be used in conjunction with the larger Heritage speaker. I just wish there was a way to coax more body out of the lower mids. I don't quite understand sealed designs, especially this one, with an enclosure that is too small for a 12" woofer, and the reasoning behind reversing polarity of the mid, and tweeter. This speaker is extremely hard to integrate with a sub! I'm sure that at least one heresy owner can concur with me! Come on guys, what are my options, besides moving to Cornwalls, because I don't have the room for them. Help!!![:'(]
