{"product_id":"dd-audio-redline-615d-d4","title":"DD Audio Redline 615d D4","description":"\u003cp\u003eThe completely redesigned Redline 600 Series offers a host of benefits over the older design. The re-engineered frames and suspension geometry result in lower Fs and more excursion potential. These two things combined give you A LOT OF BASS, especially in the lower frequency bands. The revised voice coils have increased thermal handling, reduced inductance and increased efficiency. These features translate into smoother response, more output with the same amps, and higher power handling. Aesthetic improvements have been made as well. The red double stitching line is no longer there; the red line is now visible between the cone and the thermoformed multilayer surround. The dust cap logo is made of a reflective foil layer. All cones and dust caps now feature a black matte finish. All frames are DD branded. The triple voice coil venting, laminated spiders and extended pole pieces that made DD subwoofers so exceptional are still present in these new models. The Redline 600 Series subwoofers feature 2.5″ voice coils, available in dual 2 or 4 ohms. Available sizes are 8″, 10″, 12″ and 15″\u003c\/p\u003e\n\u003ch3\u003eTechnical data\u003c\/h3\u003e\n\u003cp\u003e- 15″ subwoofer\u003cbr\u003e- 2.5″ voice coil wound of Made in USA wire\u003cbr\u003e- 2x 4 ohms\u003cbr\u003e- power handling 600 W RMS, 1800 W Peak\u003cbr\u003e- weight: 9,5 kgs\u003cbr\u003e- mounting diameter: 353 mm\u003cbr\u003e- mounting depth: 178 mm\u003cbr\u003e- x-mech: 60 mm\u003cbr\u003e- x-max: +- 13 mm\u003cbr\u003e- fs: 26,92 Hz\u003cbr\u003e- qts: 0,6797\u003cbr\u003e- vas: 114,4 litraa\u003cbr\u003e- recommended ported enclosure: 85-142 liter ( NET )\u003cbr\u003e- recommended sealed enclosure: N\/A.\u003c\/p\u003e","brand":"DD Audio","offers":[{"title":"Default Title","offer_id":53651517047125,"sku":"DDRL615d-D4","price":232.75,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1356\/2245\/files\/DD-Audio-Redline-615d-D4.jpg?v=1776126709","url":"https:\/\/www.autogarsas.lt\/en\/products\/dd-audio-redline-615d-d4","provider":"AUTOGARSAS.LT","version":"1.0","type":"link"}
