Its ported design delivers strong bass that extends down to 73 Hz.\u003c\/p\u003e\n\u003cp\u003eThe very wide 180° conical coverage of the ACS-40TS makes it particularly suitable for low ceilings and reduces the number of speakers required for even coverage — leading to a reduction in installation cost. It features a shallow backcan for installation in ceilings with a minimum cavity depth.\u003c\/p\u003e\n\u003cp\u003eIt incorporates a high-quality transformer for 70V\/100V line operation, with transformer taps selected by a rotary switch accessible behind the powder-coated, perforated steel grille. The switch also provides for 16-ohm low impedance operation — enabling four or more speakers to be driven in parallel from a single amplifier channel. For full-bandwidth protection, the low and high-frequency sections are individually against overload by auto-resetting thermal fuses.\u003c\/p\u003e\n\u003ch2\u003eProduct Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLogo-Free Design\u003c\/strong\u003e – Features a clean, unbranded finish with no Martin Audio logo\u003c\/li\u003e\n\u003cli\u003eHigh performance two-way ceiling speaker\u003c\/li\u003e\n\u003cli\u003e4” (100mm) LF driver and 0.75” (19mm) HF dome tweeter\u003c\/li\u003e\n\u003cli\u003eVery wide 180° conical coverage pattern reduces speaker count required for even coverage\u003c\/li\u003e\n\u003cli\u003e70V\/100V multitap line transformer or 16-ohm low-impedance operation\u003c\/li\u003e\n\u003cli\u003eLow and high-frequency overload protection\u003c\/li\u003e\n\u003cli\u003eUL94V-0 rated baffle with zinc-plated steel backcan\u003c\/li\u003e\n\u003cli\u003eQuick release, bezel-less grille\u003c\/li\u003e\n\u003cli\u003eTile rails and C-ring included\u003c\/li\u003e\n\u003cli\u003e5-year warranty\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRetail outlets\u003c\/li\u003e\n\u003cli\u003eCafes, bars and restaurants\u003c\/li\u003e\n\u003cli\u003eMuseums and Houses of Worship\u003c\/li\u003e\n\u003cli\u003eHotels, casinos and concourses\u003c\/li\u003e\n\u003cli\u003eTransportation facilities\u003c\/li\u003e\n\u003cli\u003eBoardrooms and reception areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTYPE: Ultra-compact, passive two-way ceiling speaker, ported bass reflex\u003c\/li\u003e\n\u003cli\u003eFREQUENCY RESPONSE (1): 106Hz-20kHz ± 3dB\u003c\/li\u003e\n\u003cli\u003e-10dB @ 73Hz\u003c\/li\u003e\n\u003cli\u003eDRIVERS:\n\u003cul\u003e\n\u003cli\u003eLF: 4” \/1” high-temp voice coil, coated paper cone, rubber surround, ferrite motor, pressed steel chassis\u003c\/li\u003e\n\u003cli\u003eHF: 0.75” silk dome, neodymium motor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eRATED POWER (2): 40W AES, 160W peak\u003c\/li\u003e\n\u003cli\u003eRECOMMENDED AMPLIFIER: VIA2004 (for low-impedance operation)\u003c\/li\u003e\n\u003cli\u003eSENSITIVITY(4): 86dB \/ 1W(4V) \/ 1m\u003c\/li\u003e\n\u003cli\u003eMAXIMUM SPL (9): 108dB peak\u003c\/li\u003e\n\u003cli\u003eNOMINAL IMPEDANCE: 16Ω\u003c\/li\u003e\n\u003cli\u003eDISPERSION (-6DB): 180° conical up to 10kHz\u003c\/li\u003e\n\u003cli\u003eCROSSOVER: 3.5 kHz passive (LF and HF auto-resetting fuses)\u003c\/li\u003e\n\u003cli\u003eTRANSFORMER TAPS:\n\u003cul\u003e\n\u003cli\u003e70V: 20w \/ 10w \/ 5w \/ 2.5w\u003c\/li\u003e\n\u003cli\u003e100V: 20w \/ 10w \/ 5w\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eRECOMMENDED HIGH-PASS FILTER: 75Hz 24dB\/oct\u003c\/li\u003e\n\u003cli\u003eENCLOSURE: UL 94V-0 rated ABS baffle with steel backcan\u003c\/li\u003e\n\u003cli\u003eFINISH: Baffle and grille: RAL9016 white Backcan: zinc plated\u003c\/li\u003e\n\u003cli\u003eGRILLE: Perforated steel, powder-coated, bayonet fitting\u003c\/li\u003e\n\u003cli\u003eCONNECTORS: Ceramic connector (in and link) located behind fire-retardant steel cover\u003c\/li\u003e\n\u003cli\u003eACCESSORIES (INCLUDED):\n\u003cul\u003e\n\u003cli\u003e2 tile rails\u003c\/li\u003e\n\u003cli\u003eC-ring backing plate\u003c\/li\u003e\n\u003cli\u003eCut-out template\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eDIMENSIONS:\n\u003cul\u003e\n\u003cli\u003e(OD) 221mm x (D) Back Can 97mm, (D) Inc.
