Displacing 16.6 litres, or half a cubic foot, per maximum stroke, Ascendo states it moves as much air as fifteen standard 18-inch subwoofers, while offering a faster group delay at the same frequencies and playing down into the single-digit hertz range.\u003c\/p\u003e\n\u003cp\u003eThis passive design connects via a Neutrik NL4 MP input terminal and requires two amplifier channels; Ascendo recommends its DSP-4D processor with the AIA2-10K2 IS amplifier. It is intended to complement cinema and home theatre systems by extending LFE channel reproduction, and to benefit high-end speaker systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eCustom-built 32-inch forward-firing woofer with dual 6.5-inch voice coil\u003c\/li\u003e\n\u003cli\u003e90 mm linear travel (45 mm each direction), with the voice coil remaining in a homogeneous magnetic field\u003c\/li\u003e\n\u003cli\u003eDisplaces 16.6 litres (half a cubic foot) per maximum stroke\u003c\/li\u003e\n\u003cli\u003eSealed enclosure with fast group delay at low frequencies\u003c\/li\u003e\n\u003cli\u003ePlays down into the single-digit hertz range\u003c\/li\u003e\n\u003cli\u003eExtends LFE reproduction in cinemas and home theatres, and complements high-end speaker systems\u003c\/li\u003e\n\u003cli\u003eInternally braced birch ply and MDF enclosure in black structural paint, floorstanding on feet\u003c\/li\u003e\n\u003cli\u003eNeutrik NL4 MP input terminal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cstyle\u003e\n  .spec-table { width: 100%; border-collapse: collapse; border: none; font-size: 0.95em; }\n  .spec-table td { padding: 9px 14px; border: none; vertical-align: top; }\n  .spec-table tr.spec-header td { background-color: #4a4a4a; color: #ffffff; font-weight: bold; text-transform: uppercase; letter-spacing: 0.04em; }\n  .spec-table tr.spec-odd td { background-color: #ffffff; }\n  .spec-table tr.spec-even td { background-color: #d0d0d0; }\n  .spec-table td:first-child { width: 40%; font-weight: 500; }\n\u003c\/style\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"spec-odd\"\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eThe32 SUB PRO Passive Sealed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-even\"\u003e\n\u003ctd\u003ePack Type\u003c\/td\u003e\n\u003ctd\u003eSingle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-header\"\u003e\u003ctd colspan=\"2\"\u003eGeneral\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr class=\"spec-odd\"\u003e\n\u003ctd\u003eSpeaker Type\u003c\/td\u003e\n\u003ctd\u003e32” forward-firing woofer with dual 6.5” voice coil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-even\"\u003e\n\u003ctd\u003eXMAX\u003c\/td\u003e\n\u003ctd\u003e45 mm excursion each direction (90 mm linear), voice coil remaining in homogeneous magnetic field, linear and lowest distortion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-odd\"\u003e\n\u003ctd\u003ePrinciple\u003c\/td\u003e\n\u003ctd\u003eSealed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-even\"\u003e\n\u003ctd\u003ePassive | Active\u003c\/td\u003e\n\u003ctd\u003ePassive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-odd\"\u003e\n\u003ctd\u003eRecommended Amplifiers\u003c\/td\u003e\n\u003ctd\u003e2 Amp. channels are required. minimum recommended amplifier voltage swing: 2 x 109 Vrms, 154 Vpk, 27.3 A; equivalent to 3000 W @ 4 Ohms per channel, total 6000 W with correct RMS \u0026amp; Peak limiter settings (up to 450 V = 20 kW peak)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-even\"\u003e\n\u003ctd\u003eRecommended ASCENDO Amplifiers\u003c\/td\u003e\n\u003ctd\u003eDSP-4D + AIA2-10K2 IS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-header\"\u003e\u003ctd colspan=\"2\"\u003eMeasured Data\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr class=\"spec-odd\"\u003e\n\u003ctd\u003eSPL Peak (Peak \/ Half Space 2pi)\u003c\/td\u003e\n\u003ctd\u003e140 dB @ 32 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"spec-even\"\u003e\n\u003ctd\u003eFrequency Range (measured, without ext.
