Heresy IV and DENTON 80 are members of Wharfedale's Heritage series of speakers. Below you can find the loudspeakers from this series.

History
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Heresy IV is a 3-way design whereas the DENTON 80 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 80 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz.
Frequency Response
Heresy IV has a frequency range of 48-20k Hz whereas DENTON 80 has a frequency range of 44-24k Hz. With a minimum frequency of 44Hz, the DENTON 80 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 80 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Heresy IV sensitivity is rated at 99 dB and the DENTON 80's is rated at 86 dB. This 13 dB difference makes the Klipsch Heresy IV a more sensitive speaker compared to Wharfedale Denton 80, 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.
Both handle the same maximum of 100 watts RMS, though Heresy IV is rated up to 100 watts and DENTON 80 20-100 watts.
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.
Which plays louder on your 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 80 features dual binding post speaker terminals for bi-amping or bi-wiring.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch Heresy IV's and Wharfedale Denton 80's external dimensions. Klipsch Heresy IV has external dimensions of 631.0 x 394.0 x 337.0mm (24-13/16 x 15-1/2 x 13-1/4inch) whereas Wharfedale Denton 80 has external dimensions of 320.0 x 200.0 x 305.0mm (12-5/8 x 7-7/8 x 12inch).
Klipsch Heresy IV is clearly the larger of the two speakers. Its body is 194mm wider, 311mm taller and 32mm deeper than Wharfedale Denton 80.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Klipsch Heresy IV needs about 118% more floor or shelf area. Klipsch Heresy IV is 32mm deeper, so it stands that much further out from the wall. Klipsch Heresy IV is 311mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Klipsch Heresy IV is approximately 1327.8cm2 / 205.8inch2 and base area of the Wharfedale Denton 80 is approximately 610.0cm2 / 94.6inch2. The Heresy IV requires 118% more surface area than the DENTON 80 which gives it a small disadvantage on placement in tight spaces.
