A bigger space demands bigger bass – and that’s exactly what the Q SUB100 provides. Its 10in driver and effortless performance make it the perfect low-frequency partner for our Concept loudspeakers, as well as every other medium-sized passive speaker in our line-up.

Introducing Q SUB series

Complete the immersive audio experience with our new high-performance active subwoofer series for breathtaking bass.

British audio specialist, Q Acoustics, introduces its new trio of high-performance active subwoofers, Q SUB series. Whether as part of a Q Acoustics home cinema set-up, adding effortless bass extension to existing 7.2, 5.1 or 2.1 systems or intensifying the low end on powered/active speakers, these new models will deliver the dramatic to movies and music.

Flexible Room Placement

Placement in a room can impact sound arrival timing, while phase alignment issues can arise even with adjacent subwoofer placement, affecting system frequency response. The Q SUB range uses Digital Signal Processing (DSP), alongside fine delay adjustments and phase inversion switch, to address these integration challenges. This technology enables users to optimise settings for a class-leading performance, ensuring seamless integration with other speakers without needing professional installation.

Source Detection

Subwoofers must accommodate a wide variety of sound input sources, including stereo preamp outputs or mono feeds from active speakers or home cinema systems. The Q SUB range uses a complex algorithm inside the DSP to identify the input signal type – stereo or mono and the level – and automatically adjusts system gain. This ensures optimal signal to noise levels and dynamic range, enhancing performance regardless of the connected source.

Classic Finish To Compliment Your Interior

The trio’s minimalist and clean design means they can blend discreetly into the room or proudly displayed to fit seamlessly into any interior space. The Q SUB series arrives in two modern but classic finishes: Satin Black with a black grille or Satin White with a grey grille. The new models join the slimline 3060S Satin to complete Q Acoustics’ subwoofer family.

Power Amplifier

The Q SUB amplifier module, custom-designed by Q Acoustics, includes a DSP, power amplifier, and power supply. It features four digital power amplifier stages in a parallel bridge-tied load (PBTL) configuration, enhancing efficiency and speaker control by reducing output impedance and heat dissipation. This design can deliver up to 300W continuous and 600W peak power, with exceptional total harmonic distortion (THD) performance of less than 0.1% up to 300W.

Frequency Response Adjustment

Subwoofers need an adjustable low pass filter to match their upper frequency response with the diminishing bass of other speakers. The Q SUB range features a low pass filter with frequency adjustment from 40 Hz to 250 Hz, setting the -6 dB point. This wide range ensures the Q SUB models can seamlessly integrate with and complement the low-frequency response of any partnering speaker system.

Driver Design

The drive units feature a heavy-duty steel chassis, paper cone, and rubber surround. Bass unit diameters are 203mm (Q SUB80), 254mm (Q SUB100), and 305mm (Q SUB120). Voice coils are 38mm for Q SUB80/100 and 50mm for Q SUB120, with an aluminium demodulation ring for reduced inductance-induced modulation distortion.

Cabinet Design

An infinite baffle (sealed box) design delivers tight, focused bass, coupled with DSP for precise acoustic tuning. With no port, placement near walls and furniture is easier. The Q SUB cabinets use 18mm high-density MDF with a 36mm double-thickness baffle for rigidity. Internal dart bracing enhances stability, reduces cabinet ballooning, and ensures optimal performance under high internal pressure.
