Klipsch!. The worst speaker company, EVER?

Very entertaining. To each his/her own, but a pair of 12” drivers shouldn’t need a subwoofer. Brash sounding with no low end. Hard pass on the Heresy.  

@thehorn- lest not forget he is writing for an UK mag and therefore catering mostly for UK readers, whose houses/apartments etc are not as generally large enough to take accommodate huuuuge loudspeakers, not forgetting UK women are less tolerant of 'clutter' than the average (joke). Mr Hughes is very knowledgable with the horn sound? as he owns a pair of the rather marvelous 3 way Impulse H1's and has had them since 1989. Wait a minute, I own a pair to!.....lol 

The Heresy IIIs aren't any sort of "white elephant" except to those who don't know what that term actually means. The exact mid horn and tweeter as Cornwalls at half the weight and price, and the price difference alone would allow the purchase of a swarm of woofers (pun intended). I'll take that efficient and smaller sized fat little box, and a couple of RELs to make things outstandingly good. I modded my Heresy IIIs by damping the mid horn after succumbing to intense and relentless pressure from outside influences, but mods? No need...I do dust them from time to time, and the latest sort of "mod" that worked around here was the new 7581A tubes in my little single ended power amp. I understand the design choice Klipsch made with the 12" woofer...utter control of the range it's utilized for, with a tight and coherent tonal presentation matching the other drivers perfectly. Klipsch has options for those with needs that require larger things, but Heresy IIIs with subs are heard to beat.

Wolfy Thank you for reinforcing my point, and if you prefer, how's a red herring? Heresy IIIs: Frequency Respose 58Hz – 20kHz
Cornwall IIIs: Frequency Respose 34Hz - 20kHz
Right off the hop the listener is missing out on 24Hz of the music spectrum.
As I stated in my post "If one purchases a pair of speakers and you have to add bells/whistles, subs, and modify (although I am an ardent advocate of mods), perhaps it's time to rethink your choice".
And what do you say? "a couple of RELs to make things outstandingly good". So now your taking up even more space with the RELs/ Heresy than you would with the Cornwalls, plus, now you're dealing with phasing issues. You also go on to say "and the price difference alone would allow the purchase of a swarm of woofers". That's economical isn't.

You're saving nothing, taking up more space, introducing phasing issues, why are you trying to make a silk purse out of a sow's ear? 
If you'd re-read what I wrote " Heresy's are not a bad sounding speaker", " The Cornwalls are such a better platform to build on".
To close the Cornwalls are easier to drive, 102dB, as opposed to the  Heresy's 99dB, plus you get a 15" bottom end driver as opposed to the 12" that comes with the Heresy, not only giving you a wider frequency response, but also fuller richer sound engineered right from the factory .

Porcine metaphors aside, I don’t buy speakers as a platform to build on as it’s more that I simply add things that fit my existing "platform" and enjoy them or toss ’em out as needed. Also, please add the term "red herring" to "white elephant" in your list of terms you might not actually understand, as knowledge can often have a calming effect. Note also that Heresy IIIs with a Swarm (an actual AudioKinesis product) would likely sound astonishingly more coherent than any Cornwall could hope for, but my RELs (with phase adjustment for days) sound pretty great so I don’t care...and I do manage to get by with 99db efficiency somehow, especially if I sit REAL CLOSE. I’ve owned this pair of RELs for years and they’re unobtrusive in my listening room to the point of being nearly invisible, so although I appreciate your concern about space, it’s a non issue in my place. The Cornwalls price, large size, and design simply don’t cut it for me in my current situation where the Heresy IIIs have worked out perfectly...right from the same factory! I’m a professional sound engineer and musician and when phase issues raise their ugly heads in my listening room I address it...Out of Here Damn Phase Issues! Like that...now I’m hungry for some herring...I prefer kippered.
