Tix8805 Posted March 13 Share Posted March 13 (edited) Hi everyone, I'm starting a new project for the heresy big version (Klipsch Forte style), the components will be: -B&c DE10 tweeter -Mid k53k with 15" horn I don't know about the woofer, I have selected a few models that I can easily find, with a price around €150 and they are: - Eminence beta 12A (this one I already have) - B&c 12NDL76 - RCF LF12X401 - Dayton pa 310-8 -The voice waf122.50 I attach the technical data sheets for each. The dimensions will be approximately 3.64cf like the FASTLANE AUDIO version with a 4" port. Which of these woofers might suit you best? I chose these because they are easy to find and affordable, but I could use others in that price range. Thank you all Tiziano Edited March 13 by Tix8805 Quote Link to comment Share on other sites More sharing options...

Woofers and Tweeters Posted March 14 Share Posted March 14 Some have used a Tangent 400 to make the larger box 'ported Heresy' speakers. I am using the Eminence Kappalite 3012 HO in my Super H. Eminence Delta 12a HO, Delta Pro 12a HO, Kappalite 3012HO, and Celestion TF1225 have all proven to work well. Quote Link to comment Share on other sites More sharing options...
Tix8805 Posted March 14 Author Share Posted March 14 (edited) Those Eminence models cost too much in Italy, the Celestion is quite affordable. Edited March 14 by Tix8805 Quote Link to comment Share on other sites More sharing options...

Tix8805 Posted March 15 Author Share Posted March 15 This is the simulation of the RCF woofer, does it seem the most suitable to me, or am I doing something wrong? Quote Link to comment Share on other sites More sharing options...
DirtyErnie Posted April 26 Share Posted April 26 It might sound a little 'dry' for most of the bass, and then have what will sound like a +3dB boost at 40. Might work pretty well, would be fine with some sort of active compression. Cabin Gain might make everything I said wrong. Quote Link to comment Share on other sites More sharing options...
