SilverSport Posted January 5, 2005 Share Posted January 5, 2005 Took the backs off my 1978 Heresys...should there be any kind of packing material in there??? I have seen pictures of the interior of Cornwalls and there was a packing material in there...nothing in my Heresys. Thanks, Bill Quote Link to comment Share on other sites More sharing options...
dbflash Posted January 5, 2005 Share Posted January 5, 2005 Mine don't have any material in them either. Danny Quote Link to comment Share on other sites More sharing options...

D-MAN Posted January 5, 2005 Share Posted January 5, 2005 PWK seemed to have an aversion to using cabinet insulation. It makes sense that the Heresy is no exception to that "rule". DM Quote Link to comment Share on other sites More sharing options...

dodger Posted January 5, 2005 Share Posted January 5, 2005 Hey Silversport: No standard Heresy ever had acoustical material or inside bracing. Only modified, like mine, has those extra materials. Those mods were done by me, not the Factory. dodger Quote Link to comment Share on other sites More sharing options...
3dzapper Posted January 5, 2005 Share Posted January 5, 2005 Bill, I put my own Accustistuff in when I rope caulked the horns and woofer basket. I also applied some asphalt sheet damping material to the top, back and sides. Those inexpensive mods tighten up the bass nicely. A couple of 2uF F&F caps and you are done!

j-malotky Posted January 5, 2005 Share Posted January 5, 2005 Since the Heresy is a sealed cabinet, adding material does no good. I assume you are trying to make the bass deeper. The Heresy design for that matter, put the 12" woofer into a small box to get the upper bass to complement the high efficent horns, hense you will never get deep bass out of a Heresy. It was not designed for low bass. JM Quote Link to comment Share on other sites More sharing options...
dodger Posted January 5, 2005 Share Posted January 5, 2005 Just looked at a K 79 -K Tweeter for Cornwall IIs. Has a small tag/sticker on the back with Company name, Model # Part number date of May 15 2002 With a black R on one side in permanent marker. This has never been opened. I'll bet it may be for phasing. Glad to see you asking questions. My belief is that if you don't you have 100 % NO. If you ask you at least bring the odds to a 50 % yes. I like the latter. dodger Quote Link to comment Share on other sites More sharing options...
SilverSport Posted January 5, 2005 Author Share Posted January 5, 2005 thanks everyone...dodger, my one tweeter has no logo but the magnet has stamped in black ink, "klipsch" and it has a big red "R" covering the stamping underneath...I can still make out klipsch...it has a 4 digit serial number "engraved" into it wheras my other with the "original has the klipsch logo on it and has a 5 digit serial number "engraved" into it.

Plus if the house was ever broken into, I want to give hernias. But really the first part is the serious. Though it did tighten the bass up. dodger EDIT POST: Just talked with 2 friends with Heresys, both set up with either a Red A or a Black A. One had a pair with A for Andy the second an O. With 3 pair set up the same and my extra tweeter for my Cornwall II, I believe the markings were for phasing. dodger Quote Link to comment Share on other sites More sharing options...
dodger Posted January 5, 2005 Share Posted January 5, 2005 Well, Andy did a great job building mine. I loved them originally, but to me, IMHO, they sound a little better after my mods. That's just an afterthought - no means implying that all should be modded. It struck me that today was the first time I paid attention to the A. dodger Quote Link to comment Share on other sites More sharing options...

With all sealed designs, a larger cabinet means lower extension. http://www.diysubwoofers.org/sld/sealed4.htm Quote Link to comment Share on other sites More sharing options...
TBrennan Posted January 5, 2005 Share Posted January 5, 2005 Dr Who---PWK didn't want lower extension. In a sealed box (and for a given size driver) lower extension comes at the cost of longer cone excursion and that means higher distortion. PWK chose limited bass and cleaner sound over bass extension. Tradeoffs. He could'a made an AR-3 if he'd wanted but who around here would wanna listen to that?
