In this review, we will be comparing HDI-3800 and HDI-3600, two Passive Floor-standing speakers by JBL Let's have a brief look at the main features
of JBL HDI-3800 and JBL HDI-3600 first before getting into our more
detailed comparison.
HDI-3800 and HDI-3600 are members of JBL's HDI series of speakers. Below you can find the loudspeakers from this series.
What size room are the JBL HDI-3800 and JBL HDI-3600 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:
In the following sections, we will get into more detail in order to better understand how the JBL HDI-3800 and JBL HDI-3600 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

HDI-3800 features a 1" Tweeter and 3 x 8" Aluminum Woofer . On the other hand, the HDI-3600 features a 1" Tweeter and 3 x 6.5" Aluminum Woofer .
Frequency Response
HDI-3800 has a frequency range of 37-30k Hz whereas HDI-3600 has a frequency range of 38-30k Hz. With a minimum frequency of 37Hz, the HDI-3800 can go slightly deeper then the HDI-3600's min frequency of 38Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing 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-3800 and HDI-3600 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. HDI-3800 sensitivity is rated at 92 dB and the HDI-3600's is at 90 dB. This 2 dB difference makes the JBL HDI-3800 a more sensitive speaker compared to JBL HDI-3600, hence will play louder with the same amount of watts.
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-3800 and the HDI-3800 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-3800 can handle a max power of 300 watts RMS from the amp the whereas HDI-3600 has a max power handling value of 250 watts RMS, 50 watts less than the HDI-3800.
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
Both HDI-3800 and HDI-3600 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both HDI-3800 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-3800's and JBL HDI-3600's external dimensions. JBL HDI-3800 has external dimensions of 1143.0 x 304.0 x 421.0mm ( 45 x 11-15/16 x 16-9/16inch) 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-3800 is clearly the larger of the two speakers. Its body is 45mm wider, 115mm taller and 76mm 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-3800 is approximately 1279.8cm2 / 198.4inch2 and base area of the JBL HDI-3600 is approximately 893.6cm2 / 138.5inch2. The HDI-3800 requires 43% more surface area than the HDI-3600 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 JBL HDI-3800 weighs 38.08kg / 83.8lbs and the JBL HDI-3600 weighs 28.09kg / 61.8lbs. This makes the HDI-3800 36% heavier than the HDI-3600.
Here is a comparison of how HDI-3800 and HDI-3600's weights compare with the average, max and min weights in Passive Floor-standing class.
