Klipsch SUB-120-BLACK Synergy Subwoofer Pair - Powerful, Tight Bass

In this review the Klipsch SUB-120-BLACK Synergy Black Label subwoofer pair is judged on who needs deep, controlled low end and why it makes sense for home theater and music setups. The biggest reason to buy is simple: these subs deliver authoritative, room-filling bass driven by a 12-in front-firing cerametallic driver and a 200 watt continuous digital amplifier, producing impactful, precise low frequencies without a muddy sound.

Key Features

• Spun Copper IMG Woofer: The spun copper front-firing cerametallic woofers deliver tight, musical bass that enhances both movie explosions and rhythm instruments.
• All Digital Amplifier: The built-in amplifier supplies 200 watts continuous and 400 watts dynamic power for reliable, punchy output at varying listening levels.
• Front-Firing Driver: The 12-in front-firing driver can be placed flexibly in a room while still producing bone-rattling low end for home theater impact.
• Low Pass and Phase Control: The low pass crossover and phase control make it straightforward to integrate the sub with almost any AV receiver and main speakers.
• Line/LFE Inputs and LED Indicator: Dedicated Line/LFE inputs and a front-mounted LED power indicator simplify hookup and status monitoring.
• Contemporary Finish: Black cabinet with copper accents provides a sleek look that blends with modern AV furniture and speaker systems.

Who It's For

The Klipsch SUB-120-BLACK is aimed at home theater enthusiasts and music listeners who want pronounced, tight bass without spending for ultra-high-end pro audio subs. It suits people with medium to large rooms who want a sub that can literally move furniture at higher levels while keeping musical detail.

It is not ideal for those who need an ultra-compact solution for tiny apartments where neighbors are a concern, or for users requiring networked or wireless subs - this model is a wired, single-purpose subwoofer intended for direct AV integration.

Pros & Cons
