{"product_id":"martin-logan-depth-215-subwoofer","title":"Martin Logan Depth 215 Subwoofer","description":"\u003cp\u003eMartin Logan's Depth series is the culmination of decades of experience in designing high performance subwoofers. These subwoofers are meticulously engineered to deliver powerful bass as cleanly as possible, making them an ideal choice for both dedicated 2 channel systems, home theater, or anything in between. The force-canceling dual woofer layout all but eliminates performance-robbing cabinet resonances, allowing the custom 12\" (Depth 212) or 15\" (Depth 215) Carbon Aerocore woofers to deliver pure bass energy without coloration. The system is backed by high-power, ultra-precise amplification controlled by a class leading 64-bit Vojtko DSP engine. All of this helps Depth achieve massive dynamic output, low distortion, and exceptional musicality.\u003c\/p\u003e\n\u003cp\u003eBecause of the high levels of force necessary to produce bass frequencies, the subwoofer cabinet itself can vibrate or resonate, which can blur or color the sound. This is why speaker cabinets must be strong and rigid to counteract these forces for the best sound quality. Depth subwoofers take this concept to the next level by featuring MartinLogan's signature distortion-reducing BalancedForce woofer topology. The dual active 12\" woofers on Depth 212 and dual active 15\" woofers on Depth 215 are arranged so they operate in exact opposition from one another. The equal and opposite forces of the woofers effectively cancel out the energy that would typically be transferred into the cabinet. This design cuts out the blur, smearing, and distortion caused by cabinet resonance, leaving only pure, articulate bass energy. Not only does this sound noticeably better, but the lower distortion means Depth subwoofers are easier to listen to at all volumes. With such low distortion, Depth subwoofers are an ideal choice to pair with reference grade loudspeakers for the ultimate audio experience. Depth Series subwoofers are designed to blend uncompromising low frequency performance with timeless, luxury design. Starting with a massively overbuilt cabinet, expertly sculpted to achieve a sleek and elegant look, every aspect of the Depth Series has been carefully crafted into a perfect fusion of both form and function.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable class=\"table table-responsive table-bordered table-striped dcf-w-100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eDepth 215\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eSubwoofer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency Response\u003c\/th\u003e\n\u003ctd\u003e18–120 Hz ±3 dB (anechoic via LFE input)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLow Frequency Transducer\u003c\/th\u003e\n\u003ctd\u003eDual active 15\" cast-aluminum basket, high excursion, Carbon Aerocore cone woofers in a BalancedForce configuration with under spider, voice coil, and pole piece venting, plus dual copper shorting rings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAmplifier\u003c\/th\u003e\n\u003ctd\u003eDual reference grade Class-D amplifiers: 4,400W Dynamic Peak (2,200W RMS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDigital Signal Processing\u003c\/th\u003e\n\u003ctd\u003eUltra high-resolution 500MHz Vojtko DSP engine with 64-bit processing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCabinet\u003c\/th\u003e\n\u003ctd\u003eExtensively braced and reinforced variable thickness (1–3\") cabinet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInputs\u003c\/th\u003e\n\u003ctd\u003eLine level: Left, Right, and LFE\u003cbr\u003eXLR: Left, Right or LFE (Right In)\u003cbr\u003eSpeaker level: Left and Right (requires banana plugs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutput\u003c\/th\u003e\n\u003ctd\u003eRCA Sub Out (outputs the sum of all connected inputs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWireless Input\u003c\/th\u003e\n\u003ctd\u003eIntegrated wireless receiver, wireless transmitter included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eControls (via Bluetooth)\u003c\/th\u003e\n\u003ctd\u003eLevel: -40 to 12dB (Min–Max)\u003cbr\u003eLow-pass filter (frequency): 35–120Hz (1° increments)\u003cbr\u003eLow-pass filter (order): Bypass, Third, Fourth\u003cbr\u003ePhase: 0–180° (1° increments)\u003cbr\u003ePhase (polarity): Normal, Inverted\u003cbr\u003ePreset listening modes: Movie, Music, Night\u003cbr\u003e20–30Hz level: ±10dB\u003cbr\u003eAnthem Room Correction (ARC Genesis): On, Off\u003cbr\u003eTone sweep (120–20Hz): On, Off, Pause (frequency)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eControls (Touch Control Interface)\u003c\/th\u003e\n\u003ctd\u003eLevel adjustment\u003cbr\u003eTone sweep\u003cbr\u003eLow-pass filter\u003cbr\u003ePhase\/Polarity\u003cbr\u003eListening mode\u003cbr\u003e20–30Hz level\u003cbr\u003eARC On\/Off\u003cbr\u003eWireless On\/Off\u003cbr\u003ePasscode lock\u003cbr\u003eLogo color\u003cbr\u003eInformation\u003cbr\u003eFactory reset\u003cbr\u003eLanguage selection\u003cbr\u003eOwner’s manual QR code\u003cbr\u003eControl app QR code\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFeet\u003c\/th\u003e\n\u003ctd\u003eIntegrated anti-vibration feet (carpet spikes included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Draw\u003c\/th\u003e\n\u003ctd\u003eStandby (wireless disabled): 0.5W\u003cbr\u003eStandby (wireless enabled): \u0026lt;2W\u003cbr\u003e*Transmitter and subwoofer combined\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions (H x W x D)\u003c\/th\u003e\n\u003ctd\u003e22.5\" x 22.8\" x 23.4\" (57.2cm x 58cm x 59.5cm)*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e173 lbs (78.5kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eGloss Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003ctd\u003e*Product height is without carpet spikes but includes the feet.
