hoosier audiofool Posted April 18, 2022 Share Posted April 18, 2022 (edited) I have had a set of these in pristine condition for years and not used very often- I have a variety of speakers from B&W to Thiel to Vandersteen. Cabinets look new and so do all the drivers. I have Heresy's and Quartets, and have used dampening material on the horns to subdue the brightness on those. These 250's don't seem to have that issue but curious if they would benefit from some internal lining material, bracing (they are already robust and heavy), or anything else. I know about Crites and have upgraded caps in others, but curious if anything else would benefit. I have purchased rosewood veneer and will be veneering the cabinets even though the birch is perfect. I run these with a Vincent SV-500-either CD (Rega) or streaming, which may be the answer as to why they don't sound bright. Thank you in advance and for allowing me to be part of your group.

Outrider 6 Posted April 22, 2022 Share Posted April 22, 2022 Welcome. You’ve found the right place to look for info. You KP-250s are one of several variations of Industrial Heresy speakers. The thread HP-1 to KP201 ( ) covers some of the other versions of your speaker, but also has specific info on the KP-250. It’s a 14 year old thread, but it spans a lot of time. The defining features of the 250 are its heavy duty woofer, the ported enclosure, and tuning for PA use. Some of these properties are less charming in home use…so people tinker. 1 Quote Link to comment Share on other sites More sharing options...
