cfelliot Posted September 20, 2010 Share Posted September 20, 2010 When I replaced my center channel with a Heresy I to go with my Heresy III L/R, I appreciated a vast improvement in sound quality in my home theater. What I’m looking for is a way to achieve the same with my surrounds. I had considered building Bob Crites CS-1 speakers for this purpose. Unfortunately, I think that it will be a little overpowering, visually, to have 7 Heresy size speakers in my smaller room. I started looking at the combination of a Crites CT-125 and a Fostex FE166En full range 6.5”. The FE166 will go high enough to facilitate a crossover in the same region as the Heresy. Installed in roughly a .4 ft^3 sealed enclosure, this would be the ideal size. Albeit, this speaker would have no low end and it would require the surround low end to be routed to the subs through the AVR. I offer the above for comments and have the following questions: Is this a valid concept? I know some are using surrounds that are the same as their fronts. The surrounds seem to be mostly effect speakers to me. Would there be a better low end speaker to use in this design? Am I just mental for even thinking this might be possible?

Groomlakearea51 Posted September 20, 2010 Share Posted September 20, 2010 We're all mental 'round here..... [Y] You might want to consult with Bob on the use of the CT-125 with other than his CS-1 arrangement. Quote Link to comment Share on other sites More sharing options...
cfelliot Posted September 20, 2010 Author Share Posted September 20, 2010 Good to know![] Bob's CS-1 doesn't use the CT125, rather a Selenium D220Ti crossed over at somewhere around 1kHz. The HM25-25 Horn he uses with it is too large for the enclosure I envision. I know this will require a custom crossover, but I think it could be a simple 1st order given the range of both drivers. If Bob doesn't chime in I will send him the question directly. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted September 22, 2010 Share Posted September 22, 2010 The CS-1 has it's own signature sound distinct from a Heresy. For my own project, I think I'd acquire more Heresy's for surrounds. Really hard to beat that option, IMO. Quote Link to comment Share on other sites More sharing options...
psg Posted September 22, 2010 Share Posted September 22, 2010 I have 3 Heresy II hanging on walls as surrounds, but if they are too big for you then they are too big for you and what you are considering seems like the next best thing.

Malcolm Posted September 23, 2010 Share Posted September 23, 2010 Might be able to make a nice speaker with the proposed combination. But it ain't going to sound like a Heresy because it doesn't have the same squawker and tweeter, which give it its signature sound. If it doesn't sound like a Heresy, what is the point? Just buy anything. Quote Link to comment Share on other sites More sharing options...
cfelliot Posted September 23, 2010 Author Share Posted September 23, 2010 I realize it is a compromise, but if the CT125 is set to the same crossover point as the Heresy the high end should match well. Isn't using a center Heresy with KHorns or LaScalas also a compromise? I just want to find the right speaker for the low end and I'm not sure the Fostex is as yet!

Malcolm Posted September 24, 2010 Share Posted September 24, 2010 The problem is not the tweeter. Folks have been replacing the K77 with the CT125. Some like it. Some don't. But it really isn't the issue. The problem is the elimination of the squawker that gives all the Heritage line much of its character. A Heresy is as close as you can get to the bigger Heritage speakers down to the squawker low end crossover point of 700 Hz. There is a bit of difference due to the lower crossover point in the bigger models but not nearly the difference you will experience if your eliminate it. Eliminate the squawker and it just ain't the same thing, although it might be nice. No cone speaker is going to sound like a Heritage squawker. It is really going to depend on your ear. If you are like me, you will likely be disappointed. Currently, my system consists of Heresys all around with a subwoofer. At one time I had 1983 Heresys with the K53 squawker driver for surrounds and earlier models with the K55 squawker driver for the rest. I found the difference in timbre annoying enough when sounds panned around the room that I replaced the surrounds with earlier Heresys.
