{"product_id":"martin-logan-dynamo-iw-o","title":"Martin Logan Dynamo IW-O","description":"\u003cp\u003e\u003cspan\u003eThe Dynamo IW-O and IW-S are both exceptional in-wall subwoofers that offer powerful bass performance in a compact form factor. While they share the same retrofittable size and dual 8\" woofer configuration, there are key differences between the two models.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe Dynamo IW-O features an open back design, whereas the IW-S has a sealed, fire-rated enclosure. This distinction impacts how the subwoofers interact with the surrounding environment. With the open back design of the IW-O, more sound will transfer into the wall, potentially causing some noise to be audible in other rooms. However, this design allows for deeper bass extension and higher output potential, delivering a more impactful bass experience.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eOn the other hand, the IW-S with its sealed enclosure provides sound containment within the wall, minimizing sound transmission to other areas of the house. This makes it an ideal choice when sound control is a priority, particularly if you want to avoid potential noise complaints from adjacent rooms.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFor those seeking a balance between sound control and higher output, the IW-O offers an additional accessory called the \"High Output Back Box.\" This optional accessory enhances sound control while still maintaining the benefits of the open back design, allowing you to achieve both a controlled listening experience and increased output capability.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eBoth the Dynamo IW-O and IW-S are designed to offer flexibility and exceptional bass performance in an in-wall installation. Whether you prioritize sound control or desire deeper bass extension and higher output, MartinLogan has provided options to meet your specific needs. Elevate your audio system with the Dynamo IW-O or IW-S and enjoy immersive bass reproduction that transforms your listening experience.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"feature-chart__table-row\"\u003e\n\u003cdiv class=\"feature-chart__value prose text-subdued\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eDesign\u003cbr\u003eDual high-excursion drivers, in-wall, GRIPTM chassis\/mounting bracket, and optional backbox\u003cbr\u003e\u003cbr\u003eFrequency Response\u003cbr\u003e+\/-3dB from 30-\u0026gt;190 Hz\u003cbr\u003e\u003cbr\u003eLow Frequency Extension*†\u003cbr\u003e25 Hz (DIN)\u003cbr\u003e\u003cbr\u003eMax input power\u003cbr\u003e400W\u003cbr\u003e\u003cbr\u003eMinimum Mounting Depth\u003cbr\u003e3-1\/2” (8.9cm)\u003cbr\u003e\u003cbr\u003eMinimum Mounting Depth\u003cbr\u003e19-1\/8” x 10-3\/4” x 3-1\/2” (48.5cm x 27.2cm x 8.9cm)\u003cbr\u003e\u003cbr\u003eLow Frequency Driver\u003cbr\u003eTwo 8” (210-mm) CFPTM carbon- fiber-reinforced polypropylene cones, 1-1\/2” (38-mm) voice coils, over- molded TPRTM surrounds, 1-1\/2” (38- mm) 8-layer copper wire voice coils, high-temperature polyamide formers, ceramic\/ferrite magnet structures\u003cbr\u003e\u003cbr\u003eInternal Volume\u003cbr\u003e88L “standard” wall cavity (26L when installed in optional backbox)\u003cbr\u003e\u003cbr\u003eSuitable Amplifier Range\u003cbr\u003e50-800W\u003cbr\u003e\u003cbr\u003eWeight\u003cbr\u003e15lbs (6.8kg) each\u003cbr\u003e\u003cbr\u003eCut-Out Dimensions\u003cbr\u003e18” x 9-5\/8” (45.7cm x 24.5cm)\u003cbr\u003e\u003cbr\u003eFinish\u003cbr\u003eWhite, paintable\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"feature-chart__table-row\"\u003e\n\u003cdiv class=\"feature-chart__heading bold\"\u003e\u003cstrong\u003eWeight \u0026amp; Dimensions\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"feature-chart__heading bold\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"feature-chart__value prose text-subdued\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eCut-Out Dimensions\u003cbr\u003e18” x 9-5\/8” (45.7cm x 24.5cm)\u003cbr\u003e\u003cbr\u003eWeight\u003cbr\u003e15lbs (6.8kg) each\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Martin Logan","offers":[{"title":"Standard","offer_id":48006539313366,"sku":null,"price":749.99,"currency_code":"CAD","in_stock":true},{"title":"Dynamo IW-O High Output Back Box","offer_id":48006539346134,"sku":null,"price":1349.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/2457\/9030\/files\/iw-o-dynamo-1100x_95c455a3-b5a4-49da-bb69-ec5051df7fd9.png?v=1774699191","url":"https:\/\/unifyav.ca\/products\/martin-logan-dynamo-iw-o","provider":"Unify AV","version":"1.0","type":"link"}
