smokarz Posted May 20, 2011 Posted May 20, 2011 great work! quick question, is the Heresy cab completely sealed? or is the back panel removable like the cornwall? Quote
jhoak Posted May 20, 2011 Posted May 20, 2011 H-IIs and H-IIIs have sealed backs. Everything goes in from the front. H-Is have removeable backs like Cornwalls. Quote
muel Posted May 20, 2011 Author Posted May 20, 2011 This is an early Heresy II (1986) model that had the round terminal cups. It is sealed and the back doesn't come off. I filled the back edge with wood glue and followed that with latex caulk. I'll get a better picture of the back. Quote
smokarz Posted May 20, 2011 Posted May 20, 2011 thanks guys, i am building cabs for the heresy clone so this help. Quote
Marvel Posted May 20, 2011 Posted May 20, 2011 is the Heresy cab completely sealed? or is the back panel removable like the cornwall? Original Heresy back is removable, the HII back is sealed. All the components come out the front. Bruce Quote
finallygotmyheresies Posted May 21, 2011 Posted May 21, 2011 The grills were easy... Klipsch still had a few sets for the Heresy II in stock. These have the velcro but the H IIIs are magnetic. If you don't mind sharing, how much do the new HII grills cost? Quote
muel Posted May 21, 2011 Author Posted May 21, 2011 The grills wound up costing over $75 shipped. Still not too bad considering time and cost of doing it myself from scratch. Maybe for my next project after I get a decent router. The grills don't come with logos. I bought new ones - Part Number: 070249 (Jubilee Pie Logo) $12. /ea. 1-800-KLIPSCH (554-7724) option 6 Quote
smokarz Posted June 2, 2011 Posted June 2, 2011 hey guys, can you tell me if the Heresy cabs have any bracing and/or damping materials?thanks Quote
moray james Posted June 2, 2011 Posted June 2, 2011 Heresy and Heresy ll none have not looked into a Heresy lll but I expect not. Theory says damping can provide about a 15 -20% increase in apparent volume so if you want to brace away you can make up volume loss with damping. Sounds like a good idea as a more rigid cabinet is always a good thing unless it's a Harbeth (or other BBC style design). Have fun and enjoy. Best regards Moray James. Quote
smokarz Posted June 2, 2011 Posted June 2, 2011 thanks james. just wondering if bracing/damping might change acoustic quality. if klipsch decided that they weren't needed, i guess i should just leave it be. Quote
moray james Posted June 2, 2011 Posted June 2, 2011 A solid well braced cabinet will be cleaner sounding and the bass will be more articulate. Extra brace and stiffening material cost in material and labor. I believe the omission was done for cost purposes and because they thought the speaker competitive enough without it. A simple mod is to solder all your connections for better sound. You can also pair and twist up the hook up wires to each driver. Some have used a dense rubber foam to wedge between the mid driver and the back of the cabinet to damp both the horn and the back of the cabinet. You may as well give your primo parts a first class home, they deserve it. Best regards Moray James. Quote

IMO. I debate with myself whether or not I should get spare pairs for my speakers. Quote
muel Posted June 3, 2011 Author Posted June 3, 2011 If you look at the first picture in this post you will see the foam rubber that was in my Heresy II cabinets. There was nothing else. I am trying the HIII components with the foam rubber still installed and a little bracing of the front cabinet to the rear. Quote
Groomlakearea51 Posted June 5, 2011 Posted June 5, 2011 hey guys, can you tell me if the Heresy cabs have any bracing and/or damping materials?thanks Heresy-I has braces for the motor board and rear panel assembly; 3/4" birch strips, no gaps, stapled. Heresy-II & III have no braces as the cabinet construction uses the motor board and rear panel as the "brace" (slotted fit). They have a piece of open cell foam inside that is in the shape of an inverted "U" over the woofer. Dampening of the sealed (acoustic suspension) enclosure does not help bass response. Slotted or ported enclosures (bass reflex) is where that design becomes commonly used. Several folks on the Forum (notably Dr. Who) can provide extensive information and "guidance" on the physics of damening, porting, etc. [H] Quote
muel Posted June 17, 2011 Author Posted June 17, 2011 Finally, here it is with grill and badge. Looks kind of small next to his big brother. Quote
Ironsave Posted June 24, 2011 Posted June 24, 2011 Muel, This was a very enjoyable thread. Thanks for taking the time to post pictures and describe your experiences.... The H IIIs (formerly H IIs) came out beautiful. As mentioned; pattern matching looks really great. Thanks again! Quote
