In this review, we will be comparing Studio 630 and HDI-1600, two Passive Bookshelf speakers by JBL Let's have a brief look at the main features
of JBL Studio 630 and JBL HDI-1600 first before getting into our more
detailed comparison.
What size room are the JBL Studio 630 and JBL HDI-1600 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 Studio 630 and JBL HDI-1600 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Studio 630 features a 1" High Frequency Compression Tweeter and 1 x 6.25" PolyPlas Woofer . On the other hand, the HDI-1600 features a 1" Horn-Loaded Tweeter and 1 x 6.5" Aluminum Woofer .
Frequency Response
Studio 630 has a frequency range of 45-40k Hz whereas HDI-1600 has a frequency range of 40-30k Hz. With a minimum frequency of 40Hz, the HDI-1600 can go significantly deeper on the low side and provide stronger bass compared to the Studio 630's min frequency of 45Hz.
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 Bookshelf class in our database.

High Frequency

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
Studio 630 is a 6 ohms speaker compared to the HDI-1600 which has a nominal impedance of 4 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-1600 can provide this impedance level.
On the other hand, they have the same sensitivity of 85 dBdB.

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.
Studio 630 can handle a max power of 200 watts RMS from the amp the whereas Studio 630 has a max power handling value of 150 watts RMS , 50 watts less than the HDI-1600.
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-1600 features 5-way post posts which make bi-amping or bi-wiring possible. Studio 630 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
JBL HDI-1600's 5-way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Studio 630 and HDI-1600 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 Studio 630's and JBL HDI-1600's external dimensions. JBL Studio 630 has external dimensions of 230 x 280 x 372mm ( 14.6 x 9-1/16inch x 11-1/16inch ) whereas JBL HDI-1600 has external dimensions of 383.0 x 232.0 x 289.0mm ( 15-1/16 x 9-1/8 x 11-3/8inch) .
JBL HDI-1600 is clearly the larger of the two speakers. Its body is 2mm wider, 11mm taller and 9mm deeper than JBL Studio 630.
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 Studio 630 is approximately 644.0cm2 / 99.8inch2 and base area of the JBL HDI-1600 is approximately 670.5cm2 / 103.9inch2. The Studio 630 requires 4% less surface area than the HDI-1600 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 Studio 630 weighs 9.02kg / 19.8lbs and the JBL HDI-1600 weighs 9.98kg / 22lbs. This makes the HDI-1600 11% heavier than the Studio 630.
Here is a comparison of how Studio 630 and HDI-1600's weights compare with the average, max and min weights in Passive Bookshelf class.
