The Heresy is one of my favorite speakers, although I should mention I have a lot of favorite speakers lol. But I prefer the series 1 over the later iterations, no Crites "upgrades"
Had two pair, sold the raw birch and kept the oiled walnut, they're currently part of my bedroom system.
The others were in the main living rm with Dayton Audio Sub1200's from Parts Express as stands, connected in stereo preserves the Heresy sound only BIGGER now with 25hz capability, real giant killers.

I modified them for biamping with the Dynaco amps on top

if you plan on setting them on the floor I like spiking them, looks good, protects the bottom of the enclosures from getting scratched, and tightens up the bass considerably

The 710s use a pair of 7” woofers, which function equivalent to a single 10” woofer but with better dynamics. Still, the system is limited in bass extension. The 810 and my 1230 use a pair of 8” woofers which function equivalent to a single 12” woofer but again with more efficiency and better dynamics. Bass extension is much better. The Heresy has a 12” woofer and would be expected to sound better at least at low frequencies than the L710 with some material.
Wasn't the Heresy originally intended for center channel use?ALthough the Heresy have 12" woofers, they are designed for very low excursion and highish efficiency, NOT deep bass.
If you expect ANY deep bass at all, they will let you down.
I see them more as similar to a semi pro speaker you could use for sound reinforcement in a small church or maybe a jazz club, and so on, not a full range bass speaker.

I never had an issue with the bass in my Heresy, I had them against a wall on the floor, and the bass was full and deep. It was the harshness of the mids and highs that I couldn't stand. Some folks love them, so maybe it's just me.that's how "you" see it, well you're absolutely wrong, as you're also wrong about the size of the "12" subs" in the picture
The Heresy needs no sub when "set up as designed", on the floor against the front wall where the bass will be augmented. They were designed this way, people used to place there speakers this way back in 1957 eh.
Try placing your bass heavy speakers designed to be out in the room against the front wall and tell me you like the muddy bass they now produce. Does this make them only useful as subwoofers lol? What a crock.
They were paired with subs because I wanted to pull them out into the room for better imaging, something most didn't care about in 1957 when the Heresy debuted eh.
The pair in the bedroom are placed as designed and need no sub, they actually have an abundance of tight, tuneful musical bass in this setup, so no, you're assessment is completely wrong.

That was my whole point about it being to subjective. They are both great speakers, op needs to listen to some horns before deciding.Some folks love them, so maybe it's just me.

Well, then it ain't just me, I was getting paranoid. But that's just me.I have not heard the L710s, but I have heard the L810s and cannot imagine two more different sounding speakers (Heresy vs L810). The bass is really not subjective, the ADCs simply go deeper than the Heresies. The horn drivers are like nails on a chalkboard to my ears vs the smooth domes of the ADC.....that is purely subjective I know.
Again, that’s basically my point… OP needs a point of “reference”. Old dudes disagreeing and stating their personal dislikes really does zero to answer what the OP “will like”.and cannot imagine two more different sounding speakers

I grew up with K-Horns and Cornwall’s so I am admittedly a Klipsch fanboy. I prefer the KG4’s I had over the 710’s, same space same gears, apparently my youngest likes them more, I offered her the 710’s and she took the KG’s
And the 710’s are great and may only go anywhere when I finally try some Tektons, Zu’s or find some Heresy's
As @Grenadeslio has mentioned, Heresy bass is not an issue for me, and many others. And how would my 8802 that pulls 95% of my amp duty do with thoseIf you have the room now maybe try a pair of Polk Monitor 7s or 10s. Heresy bass is not even on the same planet.

Edit: my bubby has had 10’s since we both bought speakers (my first KG4’s) at the Naples NATO base back in the day. So that would be an easy try. Not a big fan in his system.



I see you have enough Klipsch speakers to know the sound. For me, the heresy's need a sub but I believe you will find the clarity and liveliness to be superior and other than the Bass it will sound better than your other speakers. I like ADS but I don't think they have that mid you are looking for.Good luck, let us know ur views when u listen to Heresy. U wanna experiment or something's lacking in 710 that's making u go for Heresy?
It reads like the OP has three pairs of Klipsch speaker, so I' guessing he knows the sound and what he wants.That was my whole point about it being to subjective. They are both great speakers, op needs to listen to some horns before deciding.
