What size room are the JBL HDI-3600 and Klipsch RP-8000F speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

HDI-3600 features a 1" Tweeter and 3 x 6.5" Aluminum Woofer. On the other hand, the RP-8000F features a 1" Tractrix Horn Tweeter and 2 x 8" Cerametallic Woofer with a Crossover frequency at 1750 Hz.
Frequency Response
HDI-3600 has a frequency range of 38-30k Hz whereas RP-8000F has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-8000F can go significantly deeper on the low side and provide stronger bass compared to the HDI-3600's min frequency of 38Hz.
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
HDI-3600 is a 4 ohms speaker compared to the RP-8000F which has a nominal impedance of 8 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 HDI-3600 can provide this impedance level.
These two speakers also have different sensitivity levels. HDI-3600 sensitivity is rated at 90 dB and the RP-8000F's is rated at 98 dB. This 8 dB difference makes the Klipsch RP-8000F a more sensitive speaker compared to JBL HDI-3600, 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.
HDI-3600 can handle a max power of 250 watts RMS, whereas RP-8000F has a max power handling value of 150 watts RMS, 100 watts less than the HDI-3600.
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 HDI-3600 and RP-8000F features dual binding post speaker terminals for bi-amping or bi-wiring.
Klipsch RP-8000F's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both HDI-3600 and RP-8000F have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 JBL HDI-3600's and Klipsch RP-8000F's external dimensions. JBL HDI-3600 has external dimensions of 1028.0 x 259.0 x 345.0mm (40-7/16 x 10-3/16 x 13-9/16inch) whereas Klipsch RP-8000F has external dimensions of 1099.0 x 277.0 x 445.0mm (43-1/4 x 10-7/8 x 17-1/2inch).
Klipsch RP-8000F is clearly the larger of the two speakers. Its body is 18mm wider, 71mm taller and 100mm deeper than JBL HDI-3600.
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 JBL HDI-3600 is approximately 893.6cm2 / 138.5inch2 and base area of the Klipsch RP-8000F is approximately 1232.7cm2 / 191.1inch2. The HDI-3600 requires 28% less surface area than the RP-8000F 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 JBL HDI-3600 weighs 28.09kg / 61.8lbs and the Klipsch RP-8000F weighs 27.27kg / 60lbs. This makes the HDI-3600 3% heavier than the RP-8000F.
Here is a comparison of how HDI-3600 and RP-8000F's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - JBL HDI-3600 costs roughly 2.5x what Klipsch RP-8000F 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 | B | Klipsch RP-8000F digs deeper - 32Hz against 38Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch RP-8000F is more sensitive (98dB vs 90dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch RP-8000F is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | JBL HDI-3600 takes more power (250W vs 150W) - more in hand in a big room. |
| Size | depends | JBL HDI-3600 is easier to place; Klipsch RP-8000F is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | JBL HDI-3600: bi-amping; Klipsch RP-8000F: bi-amping. Klipsch RP-8000F sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | B | Klipsch RP-8000F is cheaper - $1,658 against $4,180, about 60% less; arguably a different class. |
A JBL HDI-3600 B Klipsch RP-8000F
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-8000F is the easier recommendation: it leads on most of the measured areas and costs less. Take JBL HDI-3600 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 38Hz anyway, so judge these on the other rows instead. Match it to your room: we rate JBL HDI-3600 the better fit for a very large room, and Klipsch RP-8000F for a mid-size room.
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.
