Drivers
One of the fundamental differences between these two speakers is that Heresy IV is a 3-way design whereas the Denton 85 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Heresy IV features a 1" titanium-diaphragm compression horn-loaded Tweeter, a 1.75" Midrange and 1 x 12" Fiber-composite Woofer. On the other hand, the Denton 85 features a 1" woven textile Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 3100Hz.
Frequency Response
Heresy IV has a frequency range of 48-20k Hz whereas Denton 85 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Denton 85 can go slightly deeper then the Heresy IV's min frequency of 48Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Heresy IV is a 8 ohms speaker compared to the Denton 85 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Denton 85 can provide this impedance level.
These two speakers also have different sensitivity levels. Heresy IV sensitivity is rated at 99 dB and the Denton 85's is rated at 88 dB. This 11 dB difference makes the Klipsch Heresy IV a more sensitive speaker compared to Wharfedale Denton 85, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Denton 85 can handle a max power of 120 watts RMS, whereas Heresy IV has a max power handling value of 100 watts RMS, 20 watts less than the Denton 85.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Heresy IV and Denton 85 features dual binding post speaker terminals for bi-amping or bi-wiring.
