Jamo J Series Subwoofers

How do four Jamo powered subwoofers compare? We looked at four of their J-Series subwoofers when they first debuted. Although introduced in 2014, these subwoofers are still available and continue to receive favorable user reviews.

About the Jamo J-Series Subwoofers

The J 10 SUB and J 12 SUB complement Jamo's Studio Speaker line (S-series). The higher-end J 110 SUB and J 112 SUB are a better match for their Concert Series line (C-Series). All four subwoofers incorporate MDF (medium density fiberboard) cabinet construction and feature a bass-reflex design.

The drivers are front-firing and additionally supported by a rear port (round on the J 10 and J 12, and slotted on the J 110 and J 112).

Jamo is based in Denmark and is part of the Klipsch Group (aka Klipsch Audio Technologies) headquartered in Indianapolis, Indiana.

Connectivity and Controls of the Jamo Subwoofers

For connectivity and control, all four subwoofers are equipped with LFE and RCA Stereo Line inputs for compatibility with any home theater receiver that has a subwoofer or two-channel preamp outputs. However, none of the subs in this line provide speaker level (hi-level) inputs, and no outputs allow multiple subwoofers to be connected together. Still, if you have a home theater receiver with dual subwoofer outputs, you can connect two subwoofers that way.

On the other hand, one connectivity bonus on the J 110 and J 112 subwoofers is the inclusion of a wireless connection port for Jamo's optional WA-2 wireless subwoofer kit (the wireless subwoofer kit is also compatible with select Energy, Klipsch, and Mirage Subwoofers). This means less cable clutter, as well as more flexibility with room placement.

For control, all four subwoofers provide:

• Auto Standby Power: This feature maintains a low power mode. When a low-frequency signal is detected, the subwoofer fully activates.
• Phase (0 or 180 degrees): This feature matches the in and out vibrations of the subwoofer's speaker cone with the rest of the speakers.
• Crossover: This setting option allows you to set the best frequency point where the subwoofer takes over from the rest of the speakers.
• Gain (volume) controls: This allows you to match the sound output of the subwoofer with the rest of your system so that when you adjust the volume using your home theater receiver, the sound level relationship between the subwoofer and the rest of the speakers remains constant.

The Bottom Line

These four subwoofers from Jamo are worth considering. Producing clean and tight bass, any of these can complement a home theater setup in a medium-size room. For large rooms, go for the 12-inch models.

Even though these subwoofers are designed to complement Jamo's Studio and Concert Series speakers, you can use these with other speaker brands if you match the crossover points of your speakers with the Jamo subs.

Also, if you are concerned about cluttering up your room, these subwoofers come in both wood and white finish. The white finish option is not a common color for a subwoofer.
