RP-4000F features a 1" Tractrix Horn Tweeter and 2 x 4" Cerametallic Woofer with a Crossover frequency at 1500 Hz. On the other hand, the A180 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 6.5" Polycellulose Woofer.
Frequency Response
RP-4000F has a frequency range of 37-25k Hz whereas A180 has a frequency range of 40-40k Hz. With a minimum frequency of 37Hz, the RP-4000F can go slightly deeper then the A180's min frequency of 40Hz.
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
RP-4000F is a 8 ohms speaker compared to the A180 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. RP-4000F sensitivity is rated at 95 dB and the A180's is rated at 90 dB. This 5 dB difference makes the Klipsch RP-4000F a more sensitive speaker compared to JBL Stage A180, 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.
A180 can handle a max power of 225 watts RMS, whereas RP-4000F has a max power handling value of 75 watts RMS, 150 watts less than the A180.
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 RP-4000F and A180 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 RP-4000F's and JBL Stage A180's external dimensions. Klipsch RP-4000F has external dimensions of 870.0 x 188.0 x 289.0mm (34-1/4 x 7-3/8 x 11-3/8inch) whereas JBL Stage A180 has external dimensions of 1045.0 x 305.0 x 369.0mm (41-1/8 x 12 x 14-1/2inch).
JBL Stage A180 is clearly the larger of the two speakers. Its body is 117mm wider, 175mm taller and 80mm deeper than Klipsch RP-4000F.
Below you can see the front view size comparison of Klipsch RP-4000F and JBL Stage A180 in scale.

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-4000F is approximately 543.3cm2 / 84.2inch2 and base area of the JBL Stage A180 is approximately 1125.5cm2 / 174.5inch2. The RP-4000F requires 52% less surface area than the A180 which gives it a small advantage 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-4000F weighs 13.18kg / 29lbs and the JBL Stage A180 weighs 17.29kg / 38lbs. This makes the A180 31% heavier than the RP-4000F.
Here is a comparison of how RP-4000F and A180's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | Klipsch RP-4000F digs deeper - 37Hz against 40Hz. A subwoofer would even that out. |
| Amplifier needs | A | Klipsch RP-4000F is more sensitive (95dB vs 90dB), so it goes louder on the same amplifier. |
| Amplifier match | A | Klipsch RP-4000F is the easier load at 8 ohms. |
| Headroom | B | JBL Stage A180 takes more power (225W vs 75W) - more in hand in a big room. |
| Size | depends | Klipsch RP-4000F is easier to place; JBL Stage A180 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Klipsch RP-4000F: bi-amping; JBL Stage A180: bi-amping. Klipsch RP-4000F sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | A | Klipsch RP-4000F is cheaper - $698 against $800, about 13% less. |
A Klipsch RP-4000F B JBL Stage A180
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-4000F is the easier recommendation: it leads on most of the measured areas and costs less. Take JBL Stage A180 if its size, looks or fit in your room suit you better. Match it to your room: we rate Klipsch RP-4000F the better fit for a small room and a mid-size room, and JBL Stage A180 for a large room. In a large or open-plan room, JBL Stage A180 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Klipsch RP-4000F is the easier speaker to get right.
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.
