tubav Posted August 11, 2011 Share Posted August 11, 2011 The old compression bolt from the cabinet back into the back center of the woofer magnet trick 'ala Herb Jeschke "Adventures with Voigt Pipes" trick? I made a thicker back, sealed the cabinet with a bead of glue all around, and have expandable oak dowel braces under tension top to bottom and side to side. This would tie it all together and hopefully give better bass note delineation instead of all the cabinet resonance masking it. I listened a little yesterday before adding braces, and was satisfied with the amount of bass but it was a little smeary because of cabinet talk. Good idea, yes or no? Everything I've done with the exception of the bead of glue is reversible and can take them back to stock in case I want to sell 'em. Thanks for any and all suggestions. My dad had Cornwalls during my college years and I've been wanting to re-visit Klipsch but don't have room enough for anything bigger than these '84 Heresy.

Groomlakearea51 Posted August 12, 2011 Share Posted August 12, 2011 Have you changed the caps yet? "Smeary" is quite often related to the old caps. The 84's have an E2 crossover, and the "oil cans", especially after 27 years are generally dried out. Quote Link to comment Share on other sites More sharing options...
tubav Posted August 12, 2011 Author Share Posted August 12, 2011 I've not taken the time yet to order the upgrade kit from Bob Crites. I was first just going to brace one cabinet and do an A/B between it and the unbraced one. Thanks for the reminder. Quote Link to comment Share on other sites More sharing options...
