{"product_id":"dynaudio-m4-mkii","title":"Dynaudio M4 MkII 4-Way Main Monitor","description":"\u003cp\u003eThe Dynaudio Acoustics M4 MkII is a 4-way main monitor for large music recording and mixing rooms. Four 300 mm MSP woofers carry the bass, two 170 mm MSP drivers cover the low mids, and an Esotar soft dome and the Esotar 3 tweeter handle the upper mids and highs. A stereo pair reaches 130 dB at 2 meters with distortion held to 1% at 90 dB.\u003c\/p\u003e\n\n\u003ch3\u003eDrivers and Crossover\u003c\/h3\u003e\n\u003cp\u003eThe woofers use 100 mm ferrofluid-cooled voice coils and run as two pairs, each pair on its own amplifier channel. The low-mid drivers have 75 mm voice coils and neodymium magnets, and both Esotar units use double-magnet motors. External crossovers split the signal at 250 Hz and 2 kHz, and a high-power passive network in the cabinet joins the upper mid and tweeter at 5 kHz.\u003c\/p\u003e\n\n\u003ch3\u003eAmplification and Installation\u003c\/h3\u003e\n\u003cp\u003eThe M4 MkII has no built-in amplifiers. Each speaker takes four channels of 500 to 1,000 W, and Dynaudio recommends its DA40\/80 DSP or DCA800\/1400 amplifiers. The cabinet is usually flush-mounted in a wall, which adds low-frequency output, and it can also stand free. Dynaudio gives 2 to 6 meters as the listening distance and recommends that a qualified engineer carry out the final alignment.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4-way hybrid design for large control rooms\u003c\/li\u003e\n  \u003cli\u003eFour 300 mm MSP woofers with 100 mm ferrofluid-cooled voice coils\u003c\/li\u003e\n  \u003cli\u003eTwo 170 mm MSP low-mid drivers with neodymium magnets\u003c\/li\u003e\n  \u003cli\u003eEsotar soft-dome upper midrange and Esotar 3 tweeter with double-magnet motors\u003c\/li\u003e\n  \u003cli\u003e130 dB maximum SPL at 2 m from a stereo pair\u003c\/li\u003e\n  \u003cli\u003eFlush-mount or free-standing installation\u003c\/li\u003e\n  \u003cli\u003e4 mm binding posts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 4-way hybrid, external amplification\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Music recording and mixing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 35 Hz to 20 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum SPL:\u003c\/strong\u003e 130 dB at 2 m (stereo)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrossover frequencies:\u003c\/strong\u003e 250 Hz, 2 kHz, 5 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal harmonic distortion:\u003c\/strong\u003e 1% at 90 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTweeter:\u003c\/strong\u003e Esotar 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUpper midrange:\u003c\/strong\u003e Esotar soft dome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow midrange:\u003c\/strong\u003e 2 x 170 mm MSP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWoofers:\u003c\/strong\u003e 4 x 300 mm MSP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e LF 2 x 4 ohms, LMF 4 ohms, MF\/HF 4 ohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended amplifier power:\u003c\/strong\u003e Four channels per speaker, 500 to 1,000 W per channel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmplifier recommendation:\u003c\/strong\u003e Dynaudio Acoustics DA40\/80 DSP, DCA800\/1400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnectors:\u003c\/strong\u003e 4 mm binding posts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (H x W x D):\u003c\/strong\u003e 900 x 850 x 680 mm (35.4 x 33.5 x 26.8 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 145 kg (320 lb)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black textured paint\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dynaudio","offers":[{"title":"Default Title","offer_id":67380120781049,"sku":"M4+MKII","price":32999.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/dynaudio-m4-mkii-1.jpg?v=1792175904","url":"https:\/\/blackoutaudio.com\/products\/dynaudio-m4-mkii","provider":"Blackout Audio","version":"1.0","type":"link"}
