RP-504C II features a 1" titanium Tractrix Horn Tweeter and 4 x 5.25" Cerametallic cone Woofer with a Crossover frequency at 1950 Hz. On the other hand, the Story features a 1" anodized aluminum Tweeter and 2 x 5.25" woven Kevlar Woofer.
Frequency Response
RP-504C II has a frequency range of 50-25k Hz whereas Story has a frequency range of 48-23k Hz. With a minimum frequency of 48Hz, the Story can go slightly deeper then the RP-504C II's min frequency of 50Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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
RP-504C II and Story have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-504C II sensitivity is rated at 96 dB and the Story's is at 91 dB. This 5 dB difference makes the Klipsch RP-504C II a more sensitive speaker compared to KLH Story, hence will play louder with the same amount of watts.
Sensitivity
Center Channel 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.
RP-504C II and Story have the same power range of up to 150 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
RP-504C II features Binding post type posts and Story has a Binding post type posts. None of these speakers feature bi-amping/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 RP-504C II's and KLH Story's external dimensions. Klipsch RP-504C II has external dimensions of 177.0 x 818.0 x 385.0mm (6-15/16 x 32-3/16 x 15-1/8inch) whereas KLH Story has external dimensions of 181.0 x 486.0 x 251.0mm (7-1/8 x 19-1/8 x 9-7/8inch).
KLH Story is 332mm narrower and 134mm less deeper than Klipsch RP-504C II but it is also 4mm 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 RP-504C II is approximately 3149.3cm2 / 488.1inch2 and base area of the KLH Story is approximately 1219.9cm2 / 189.1inch2. The RP-504C II requires 158% more surface area than the Story which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Klipsch RP-504C II weighs 16.50kg / 36.3lbs and the KLH Story weighs 7.27kg / 16lbs. This makes the RP-504C II 127% heavier than the Story.

These sit in different price classes - Klipsch RP-504C II costs roughly 1.7x what KLH Story does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (50Hz vs 48Hz). |
| Amplifier needs | A | Klipsch RP-504C II is more sensitive (96dB vs 91dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (150W vs 150W). |
| Size | depends | KLH Story is easier to place; Klipsch RP-504C II is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | KLH Story is cheaper - $480 against $799, about 40% less; arguably a different class. |
A Klipsch RP-504C II B KLH Story
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Klipsch RP-504C II is ahead, but only on 1 of the measured areas, and it costs about 66% more. That is a lot of money for a narrow margin on paper - KLH Story looks like the sensible buy unless something else about the Klipsch RP-504C II appeals to you. In a large or open-plan room, Klipsch RP-504C II has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KLH Story is the easier speaker to get right. If your amplifier is modest, vintage or valve-based, Klipsch RP-504C II is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
