In this review, we will be comparing two different type of speakers by JBL. JBL HDI-3800 is a Floor-standing speaker whereas the HDI-4500 is a Center Channel speaker.
Let's have a brief look at the main features
of JBL HDI-3800 and JBL HDI-4500 first before getting into our more
detailed comparison.
HDI-3800 and HDI-4500 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-4500 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-4500 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-4500 features a 1" horn-loaded high-frequency compression Tweeter and 4 x 5.25" Advanced Aluminum Matrix cone Woofer .
Frequency Response
HDI-3800 has a frequency range of 37-30k Hz whereas HDI-4500 has a frequency range of 50-30k Hz. With a minimum frequency of 37Hz, the HDI-3800 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 Floor-standing class in our database.

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-4500 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-4500's is at 90 dB. This 2 dB difference makes the JBL HDI-3800 a more sensitive speaker compared to JBL HDI-4500, 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-4500 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
HDI-3800 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-3800 and HDI-4500 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-4500'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-4500 has external dimensions of 197.0 x 842.0 x 310.0mm ( 7-3/4 x 33-1/8 x 12-3/16inch) .
JBL HDI-4500 is 946mm shorter and 111mm less deeper than JBL HDI-3800 but it is also 538mm 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-3800 is approximately 1279.8cm2 / 198.4inch2 and base area of the JBL HDI-4500 is approximately 2610.2cm2 / 404.6inch2. The HDI-3800 requires 51% less surface area than the HDI-4500 which gives it a small advantage on placement in tight spaces.
