HDI-4500 features a 1" horn-loaded high-frequency compression Tweeter and 4 x 5.25" Advanced Aluminum Matrix cone Woofer . On the other hand, the HDI-3600 features a 1" Tweeter and 3 x 6.5" Aluminum Woofer .
Frequency Response
HDI-4500 has a frequency range of 50-30k Hz whereas HDI-3600 has a frequency range of 38-30k Hz. With a minimum frequency of 38Hz, the HDI-3600 can go significantly deeper on the low side and provide stronger bass compared to the HDI-4500's min frequency of 50Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Center Channel class in our database.

High Frequency
Center Channel Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
HDI-4500 and HDI-3600 have the same Impedance of 4 ohms and their sensitivity is also same at 90 dB.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the HDI-4500 and the HDI-4500 can provide this impedance level.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
HDI-4500 and HDI-3600 has the same power range of 20-250 watts.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
HDI-3600 features 5-way post posts which make bi-amping or bi-wiring possible. HDI-4500 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both HDI-4500 and HDI-3600 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
Size of a speaker can sometimes become 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-4500's and JBL HDI-3600's external dimensions. JBL HDI-4500 has external dimensions of 197.0 x 842.0 x 310.0mm ( 7-3/4 x 33-1/8 x 12-3/16inch) whereas 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) .
JBL HDI-4500 is 831mm shorter and 35mm less deeper than JBL HDI-3600 but it is also 583mm wider.
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-4500 is approximately 2610.2cm2 / 404.6inch2 and base area of the JBL HDI-3600 is approximately 893.6cm2 / 138.5inch2. The HDI-4500 requires 192% more surface area than the HDI-3600 which gives it a small disadvantage on placement in tight spaces.
