Q Acoustics Q SUB100   Flexible about placement Badly positioned subwoofers can impact sonic timing and cause phase alignment issues. But Q SUB has digital signal processing, a phase inversion switch and delay adjustment to provide superb performance and smooth integration without professional installation.   Source detection Subwoofers must work with input sources including stereo preamps, mono feeds from active speakers, and home cinema systems. Q SUB uses its processing power to identify the input signal type and level and automatically adjusts to deliver optimal performance. Classic finishes Q SUB’s minimalist clean design means it can blend discreetly into any room or proudly displayed. It arrives in two modern-yet-classic finishes: Satin Black with a black grille, or Satin White with a grey grille - joining 3060S to complete our subwoofer family. The power to perform The custom-designed Q SUB amplifier module includes DSP, power amp and power supply. It has four digital power amp stages in a parallel bridge-tied load arrangement, enhancing efficiency and control by reducing output impedance and heat dissipation. This configuration can deliver up to 200 watts of continuous power and 400 watts peak, with exceptional total harmonic distortion numbers of under 0.1%. Frequency response adjustment Subwoofers need an adjustable low-pass filter to match their upper frequency response with the lowest bass of their partnering speakers. Q SUB features a low-pass filter with frequency adjustment from 40Hz to 250Hz - this wide range ensures Q SUB will seamlessly integrate with and complement the low-frequency response of any speaker system. Rigorous driver design The Q SUB drive units feature a heavy-duty steel chassis, paper cone, and rubber surround - driver diameters are 203mm for Q SUB80, 254mm for Q SUB100 and a mighty 305mm for Q SUB120. Voice coils are 38mm for SUB80 and SUB100, while SUB120 uses a 50mm version - each has an aluminium demodulation ring for reduced inductance-induced modulation distortion. Uncompromised cabinet design An infinite baffle, or sealed box, design delivers tight, focused bass especially when coupled with DSP for precise acoustic tuning, and placement near walls or furniture is easy as there’s no port. Q SUB cabinets use 18mm MDF with a 36mm baffle for rigidity, while internal dart bracing enhances stability and ensures optimal performance even under high internal pressure.  Specifications  < /p> Enclosure type: Infinite baffle
