What size room are the PSB Synchrony T800 and JBL HDI-3800 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the PSB Synchrony T800 and JBL HDI-3800 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Synchrony T800 is a 3-way design whereas the HDI-3800 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Synchrony T800 features a 1" titanium with ferrofluid cooling and neodymium magnet Dome Tweeter , a 5.25" Midrange and 3 x 8" Cast Basket Carbon Fibre Cone Woofer with a Crossover frequency at 450Hz and 1800Hz. On the other hand, the HDI-3800 features a 1" Tweeter and 3 x 8" Aluminum Woofer .
Frequency Response
Synchrony T800 has a frequency range of 21-23k Hz whereas HDI-3800 has a frequency range of 37-30k Hz. With a minimum frequency of 21Hz, the Synchrony T800 can go significantly deeper on the low side and provide stronger bass compared to the HDI-3800's min frequency of 37Hz.
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.

Floor-standing Speakers
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
Synchrony T800 and HDI-3800 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Synchrony T800 sensitivity is rated at 89 dB and the HDI-3800's is at 92 dB. This 3 dB difference makes the JBL HDI-3800 a more sensitive speaker compared to PSB Synchrony T800, 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 Synchrony T800 and the Synchrony T800 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.
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 Synchrony T800 and HDI-3800 features dual binding post speaker terminals for bi-amping or bi-wiring.
PSB Synchrony T800's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Synchrony T800 and HDI-3800 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 PSB Synchrony T800's and JBL HDI-3800's external dimensions. PSB Synchrony T800 has external dimensions of 1212 x 377 x 396mm ( 47 3/4 x 14 7/8 x 15 5/8-inch) whereas JBL HDI-3800 has external dimensions of 1143.0 x 304.0 x 421.0mm ( 45 x 11-15/16 x 16-9/16inch) .
JBL HDI-3800 is 73mm narrower and 69mm shorter than PSB Synchrony T800 but it is also 25mm deeper.
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 PSB Synchrony T800 is approximately 1492.0cm2 / 231.3inch2 and base area of the JBL HDI-3800 is approximately 1279.8cm2 / 198.4inch2. The Synchrony T800 requires 17% more surface area than the HDI-3800 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 PSB Synchrony T800 weighs 45.40kg / 99.9lbs and the JBL HDI-3800 weighs 38.08kg / 83.8lbs. This makes the Synchrony T800 19% heavier than the HDI-3800.
Here is a comparison of how Synchrony T800 and HDI-3800's weights compare with the average, max and min weights in Passive Floor-standing class.
