New to the Heresy Game - Bass?

Recommended Posts

Geez; I gotta be the contrarian here. I recently bought a pair of Heresy II's for my condo and my speaker placement is virtually the same as the OP; one in a corner, one is not. Both are within a foot of the rear wall. The only difference is, mine are on the tilt risers.

 

While the Heresy's are rated to 55Hz, the same as the 6.5" bookshelf speakers they replace, the bass from the Heresy's is outrageously beyond what the bookshelf speakers were capable of producing! I don't dare go any lower or louder without pissing off my neighbors.

 

Since you've already checked polarity, I'd say either you're spoiled by your old speakers or it's the environment/placing of the speakers. Maybe there's a real difference between the Heresy I.5's and II's but I'd think it's only in terms of efficiency and not low end roll off.

 

I'm of the school that pretty much any receiver or amp can drive the Heresy's, so I don't think the Heresy's are the problem.

 

I'd lover to read what you find as a solution, outside of adding a subwoofer.

I'd definitely recommend using a power amp and preamp instead of a receiver. In my (relatively limited) experience, any kind of receiver is just going to be a weaker sound than even a middle-ground power amp.

 

That said, I listen with a pair of Heresy 2s (technically KP-201s, but same idea) and the bass output is very 'polite.' The Heresy is a speaker that you will laud for its refined sound and incredible midrange. Anything is listenable on it, it's always musical, and you would have a hard time finding the limits of its dynamics. If I understand correctly, the 12" driver is made to supplement the midrange, not fill in the bass, and it has an intentional low-excursion design in order to facilitate using less movement to create the desired frequencies. True to form, it's very low distortion, but at the expense of bass.

 

I use mine with a Klipsch Sub-12, which is a bottom-rung Klipsch 12", but it fills in the bass very well. There's not as much low-end punch as when I use the same setup with my RP-280Fs or KG 5.2s, which both make good bass on their own, but for most material I get more out of the better midrange and treble than I do from more bass. (Sometimes I switch to the other speakers for video games)

 

Without a sub, they're very bass-shy to my ear. I wouldn't run them without a sub, but I also wouldn't run a sound system without them.

Peter P.,

 

The Heresy II is a better balanced speaker.  It really doesn't have low bass but put in the corner and close to the floor, they sound deeper than they really go.  I had both of these types of Heresys at the same time (for years) and unless you like bright sound, the IIs won in the sound department.

Cornwallace - Great looking Heresy's. I have the H2 and H3's and I prefer a sub. I listen to the same music as you and wanted to feel the kick drums. I built two 25hz tapped horn subs (very easy to do) and could not have been happier at that time. Good luck with your audio journey.

It's not uncommon for a modern 10" sub to dig way lower than an older 12" fuller range woofer. The drivers are constructed differently (one for exclusively low frequencies, one for up to 700hz or higher). The subwoofer driver is most likely lower sensitivity and higher power handling, as there's always a trade-off between sensitivity and depth all else equal. The sub is ported, while the Heresy is not, and probably has a more optimized box volume for bass. So that's all going to make a big difference, as is the fact that you can't level match the more sensitive Heresy horns and the less sensitive woofer unless you're using EQ, while you can and I'm sure will level match the Heresy and the sub, either by measurements, auto correction, or ear. All of that is going to play a bigger role in sub vs Heresy sound than a vintage receiver.
