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 250 watts RMS from the amp the whereas Studio 630 has a max power handling value of 150 watts RMS , 100 watts less than the Studio 690.

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

Studio 690 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 Studio 690's 5-Way post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Both Studio 630 and Studio 690 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 Studio 690'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 Studio 690 has external dimensions of 1096.0 x 299.0 x 383.0mm ( 43-1/8-inch x 11-3/4-inch x 15-1/16-inch) .

JBL Studio 690 is clearly the larger of the two speakers. Its body is 69mm wider, 724mm taller and 103mm 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 Studio 690 is approximately 1145.2cm2 / 177.5inch2. The Studio 630 requires 44% less surface area than the Studio 690 which gives it a small advantage on placement in tight spaces.
