Q Acoustics lauches three new subwoofers in the form of the Q SUB series.

Three subs of different sizes to fit the size of your space or home cinema room. The new subwoofer family consists of the 8-inch Q SUB80, the 10-inch Q SUB100 and a 12-inch

model, Q SUB120. They all come with on-board Digital Signal Processing (DSP )for easy but comprehensive system and room integration and setting optimisation for a class-leading, distortion-free performance.

As always, the trio of subs aethetically match up with the minimalist and clean design of other Q Acoustics product, which help to fit discreetly into your room or blend seamlessly into your 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 to complete Q Acoustics’ subwoofer family.

Q SUB series audio innovations include:

Digital Signal Processing (DSP) allows easy system and room integration with optimised settings for class-leading, distortion-free performance.
Clever, dual phase and delay controls allow the fine-tuning of the signal alignments for flexible room placement.
DSP identifies the input signal and automatically adjusts system gain, enhancing performance regardless of the connected source.
A low pass filter with frequency adjustment ensures seamless integration with any partnering speaker system.
A custom-designed amplifier module features four digital power amplifier stages that improves efficiency by dissipating less heat, enhances speaker control, and reduces output impedance.
An infinite baffle box design presents a tighter and more focussed bass response, combining with DSP for very precise tuning to achieve the best acoustic response possible.
Internal Dart-bracing improves mechanical stability, reduces cabinet ballooning, and ensures optimal performance under high internal pressure.
A 12V trigger input allows automatic power-up when a trigger signal is present.

More from the Press Release:

The Q SUB amplifier offers multiple standby modes to suit various system needs. Auto detection powers the subwoofer when a signal is detected, reverting to standby after 20 minutes of inactivity, while a low-consumption power supply keeps power consumption during standby mode to an absolute minimum. A 12V trigger input allows automatic power-up when a trigger signal is present. Alternatively, the subwoofer can be set to remain permanently powered.

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 THD performance of less than 0.1% up to 300W.

Protection
An intelligent protection system constantly monitors the electronics to ensure that the amplifier and power supply are fully protected in the unlikely event of excesses of temperature.

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 is ideal for a subwoofer. Acoustically, this will present a tighter and more focussed bass response and, coupled with the DSP, allows for very precise tuning to achieve the best acoustic response possible. With no port to accommodate, the subwoofer is also easier to place in proximity to walls, corners and furniture than a ported design.

The Cabinets are are made from 18mm high-density MDF with a 36mm double-thickness baffle for exceptional rigidity. Internal dart bracing provides mechanical grounding for the drive unit, as well as mechanical stability, reduced cabinet ballooning, and ensures optimal performance under high internal pressure. A sealed enclosure also prevents air leaks through the amplifier mountings, while the 15mm MDF grilles are securely fixed to prevent rattling. Adjustable, locking spikes and spike cups are included for floor-levelling and protection.
