Subwoofer for JBL 104

The JBL 104 is an affordable and very compact studio monitor without compromising the sound quality. These highly rated mini-monitors will be suitable for listeners who have a small listening room with limited space. The small footprint of the JBL 104 allows us to fit them into tight spaces but it does limit their bass reproduction due to their compact size.

This is where an active subwoofer will help to supplement the overall bass performance of your monitoring system and deliver the missing subterranean low frequencies. It will be best to get a high-quality subwoofer that will match the JBL 104 studio monitors. The type of powered subs to go for will also depend on your own subwoofer requirements which we need to work on as well.

Sonic Characteristics of the JBL 104 and Your Subwoofer Requirements

The JBL 104 is small and has a unique cabinet shape that looks rather stylish. There is a 0.75″ (19mm) soft dome HF driver and a 4.5″ (118mm) LF driver with a rear-firing bass port. The maximum Peak SPL is only at 102dB and this is good enough for nearfield listening distance. Its frequency response is between 60Hz to 20Hz (+/-3dB) which we weren’t expecting. Still, based on this range, the JBL 104 will certainly benefit from having the support of an active subwoofer. Each mini-monitor is getting 30 Watts of power coming from a Class D amplifier. There is a JBL 104-BT version where it comes with Bluetooth connectivity.

Another pleasant surprise which the JBL 104 gave us will be its bass performance as we were expecting almost non-existent bass reproduction. The small studio monitors were able to pump out tight low ends with agility. Even so, the overall sound reproduction still sounds a bit on the lean side and you certainly need a subwoofer to produce the subsonic bass frequencies as they are missing. To have more punch and fuller sound quality, you will require a subwoofer with higher crossover frequency options. We suggest going with a 100Hz crossover setting but you might want to do some experiments on your own with this.

You should also consider getting a studio subwoofer if you are using the JBL 104 for work. As studio subs are more accurate and cleaner than consumer-grade subs within the same price range. The JBL 104 has a high level of clarity and details of the upper registers can clearly be heard. Subtle nuances and details are not as obvious but it is still present. They have a neutral sonic characteristic and depending on the music being played, the 104 mini-monitors might sound very bright. There are times where we do find the active monitors to have decent low-frequency weight and a hint of warmth.

JBL 104 may not be the best studio monitors out on the market, but the price it is asking for and the sonic performance it is giving us still make them a top speaker choice in their price group. There are probably some monetary reasons when getting a pair of budget studio monitors and you might want to work on a comfortable amount which you are willing to invest in an active subwoofer. This will also help you to remove subwoofers that are priced above your allocated budget. Space limitations could be another reason when getting a compact size monitor like the JBL 104, there are plenty of small subwoofers to choose from so no worries.

Small subwoofers may have limited crossover range and are not able to dig deeper into the bass extension. You might want to set a requirement on these two aspects. If you need to fill medium to large size listening rooms, you will probably need a bigger subwoofer. We also suggest using another pair of larger studio monitors as the JBL 104 is more suited to be used in a small studio. Please do add in more subwoofer requirements on your own.
