Klipsch Heresy IV

I payed $1600 new Canadian for my Heresy 3’s yes they were on sale regular list price in Canada is I believe $2200. the 4’s are $4k. Electronics for Less has them for $2200 each. sigh...…...so yes double. hopping for a sale or discount later in the year maybe. or La Scala’s mmmm La Scala’s

If you have Heresy 3’s (or any of their heritage line) an easy tip dyi is horn and cabinet damping. get some Dynamat 2’x4’ sheet is enough for both speakers. put it on all the back side of the horn drivers to damp the horns. also damp the bass driver’s metal frame. that will use half the sheet use the rest to put on the inside back, side and top of the cabinet. you don’t need full sheets on the inside of the cabinet I just use 5"x12" strips on the sides and top and a 12"x"12 on the back just behind the midrange and tweeter.
this will help immensely with detail retrieval, cabinet resonance issues (somewhat I’d rather put in braces but this is easy for now) and focus. cost me $120 for the Dynamat, a screwdriver and a couple hours of time.

I’m betting that would help all Klipsch heritage speakers from any year. damping the horns is really noticeable.

I found the dynamat at a car audio installation shop home depot I believe has it on their website too. 

I may get a new crossover with better parts as well GR research has some interesting DYI upgrade products. oh they have a full upgrade kit for the Forte 3 as well supposed to be excellent and includes the damping mat, braces and crossovers. 

Thanks for clearing that up Steve.  I've been forced to put some of my speakers in less than ideal positions, but whenever possible I get them out into the room.  I had some Klipsch KLF-30s that got moved into my bedroom for a while and were right up against the wall and just a couple of feet from the foot of my bed.  Far from ideal, but I wasn't playing them at high volumes in there and they actually sounded quite good.  I sold them recently to free up the space.  That was one of the few times when I struggled to let some of my gear go, they were great speakers (at their price point).

I have some Heresy I speakers from the mid-80's that I've upgraded with Crites crossovers, tweeters, and woofers.  They are fun speakers and easy to listen to.  They don't have the detail, soundstage, or imaging of my Harbeth speakers, but they are really good.  I've heard some of the newer Klipsch Heritage speakers, but not the newer Heresy.  I wondered if adding ports to them would be a good thing or not, sounds like it's a good move on the part of Klipsch.

Good day folks.  New here, but I'm configuring a system with the Heresy 4 speakers and Steve talks about not using them with a cheap a/v receiver.  Since these would be used as front speakers in a HT system, what a/v receiver would you  recommend Steve?  

My guess is that over 50% of the time they would be used for music in stereo. I've had a Marantz 2270 back in the day and I'd be starting from scratch with this.  Thanks if anyone else has thoughts on this.

Consider separate amplification for home theater and stereo listening.  A two channel integrated with home theater bypass or an amp/preamp combo with HTBP.
