As a result, unlike the previously released 212\/SE, the new S\/812 represents a complete revision of the line-up that adds new upgrades and design features.<\/p>\n<p>For a start, the cabinet has been revised, and the feet replaced with rails. The NextGen5 amplifier has also been upgraded to deliver more power, and the ultra-lightweight ContinuousCast alloy cone redesigned to handle the increase in slam. Improved filters tailor the LFE channel to deliver twice the output between 19 and 35Hz, while the high-level and low-level inputs use a new PerfectFilter. Finally, these redesigned subwoofers can also be stacked up to three units high.<\/p>\n<p>The REL S\/812 has a completely redesigned cabinet that is lower, wider and deeper, using dimensions based on the company\u2019s Reference Series. The build quality is superb, and despite essentially being a cube, the S\/812 is unusually attractive for a subwoofer. This is the kind of sub you wouldn\u2019t mind having on display, rather than hidden away in a dedicated home cinema.<br \/>\n<!--more--><br \/>\n<strong>In the real world, bass has width, depth and height, so by stacking these subs, you create a bigger bass presence from a smaller footprint<\/strong><\/p>\n<p><strong>REL S\/812 Subwoofer Review<\/strong><br \/>\n<span style=\"color: #868686; font-size: 15px;\">The <\/span><a style=\"font-family: Arial, sans-serif; font-size: 15px; font-weight: 300;\" href=\"https:\/\/rel.net\/shop\/powered-subwoofers\/serie-s\/s-812\/\">REL S\/812<\/a><span style=\"color: #868686; font-size: 15px;\">\u00a0is an impressive subwoofer that effortlessly combines style, build quality and performance into a mid-range model that can hold its own against any of the competition. The combination of the 12-inch driver and matching 12-inch passive radiator ensures some serious low-end extension, and the amplification has power to spare. The S\/812 delivers deep and controlled bass that\u2019s handled with speed and agility, seamlessly blending with the other speakers in your system to create a fully integrated soundstage.<\/span><\/p>\n<p>Link to product:\u00a0<a href=\"https:\/\/rel.net\/shop\/powered-subwoofers\/serie-s\/s-812\/\" target=\"_blank\" rel=\"noopener noreferrer\">REL S\/812<\/a><br \/>\nLink to review:\u00a0<a href=\"https:\/\/www.avforums.com\/reviews\/rel-s812-subwoofer-review.16886\" target=\"_blank\" rel=\"noopener noreferrer\">AV Forums<\/a><br \/>\nLink to Award: <a href=\"https:\/\/rel.net\/wp-content\/uploads\/2020\/12\/AVforumsS812-award.pdf?fbclid=IwAR1UpDNJjTsBQGQyLcpUMn6OSkOwlOuGaNX2RK40wRp2zwMITLZi8DE6ltU\" target=\"_blank\" rel=\"noopener noreferrer\">Best High End Subwoofer 2020<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>The\u00a0REL S\/812\u00a0forms part of the pretentiously titled Serie S range of subwoofers, but\u00a0never a company&#8230;<\/p>","protected":false},"author":2,"featured_media":24229,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[171,176,179,174],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v17.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>REL S\/812 &gt; Best High End Subwoofer 2020 - INTEK HI-FI<\/title>\n<meta name=\"description\" content=\"S\/812 takes REL\u2019s medium chassis concept to reference-like levels of performance and does so with style, beauty and devastating power.

This latest S range is a triumphant development that has exceeded every expectation of our design team.Our requirements were for far stronger deep bass output between 19-35 Hz, vastly improved theatre dynamics, and an even more open and spacious soundfield which benefits both music and film. We turned to our NextGen5 amplifier, tuned to 800 watts, with huge reserves of power beyond this, added a light film of carbon fibre to the rear of the driver to handle the extra power, and developed two new sets of custom filters to extract the utmost in brute force and spaciousness. Finally, we imbued 812 with the ability to be stacked in 4- or 6-unit line arrays, just like our reference models. Invisible Upgrades to S\/812\u2019s Bass EnginePURE CARBON FIBER BACKINGS\/812 required upgrades to its ContinuousCast\u2122 Alloy Cone to allow it to survive the massive power upgrades. To permit its thin, aluminum cone to survive 800 watts and incredibly long stroke, we added an ultra-lightweight backing of pure carbon fibre, strategically placed over portions of the rear surface of the cone. This produces two benefits; it strengthens and stiffens the cone and also eliminates reversion, wherein the backwave inside the cabinet is now prevented from interfering with the main launch of bass into the room. The result is more accurate and far louder deep bass. There is Nothing Passive About TheseCARBON PASSIVE RADIATOROur uniquely tuned passive radiators use special suspensions, now with an additional 30mm of linear travel, to produce performance far beyond conventional subwoofers. Our new SuperProgressive\u2122 passive radiator produces extremely long travel allowing for very loud output while retaining the variable stiffness of its suspension. This allows it to act like a sealed box compact 12\u201d design at low volume and a high output 14\u201d design at its limit. Warning: Power Amplifier on Steroids800 WATTS AND COUNTINGAt 800 watts the NextGen5 amplifier is borrowed from our reference models and rocks huge reservoirs of power and current. The 45% increase in power (previous version was 500 watts) is needed to deliver both the profound output levels needed for modern theatre, as well as to produce the deepest bass in a high end 2-channel system. This increase in power is necessitated by our development on the musical front of an all-new circuit termed PerfectFilter\u2122 that balance both frequency extremes.PerfectFilter performs two seemingly disparate qualities; extending the strong, even response of the extreme low end of bass frequencies while simultaneously opening up air and delicacy in the middle and high frequencies of one\u2019s system. Additionally, we applied customized PureTheatre\u2122 filters to allow S\/812 to deliver the most awe-inspiring theatre effects ever offered in a classic REL.","breadcrumb":{"@id":"https:\/\/intek-hifi.com\/en\/rel-s812-best-high-end-subwoofer-2020\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/intek-hifi.com\/en\/rel-s812-best-high-end-subwoofer-2020\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/intek-hifi.com\/en\/rel-s812-best-high-end-subwoofer-2020\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/intek-hifi.com\/"},{"@type":"ListItem","position":2,"name":"REL S\/812 > Best High End Subwoofer 2020"}]},{"@type":"Person","@id":"https:\/\/intek-hifi.com\/#\/schema\/person\/02fa1742be92272c2fe50f2579f320e7","name":"darko","image":{"@type":"ImageObject","@id":"https:\/\/intek-hifi.com\/#personlogo","inLanguage":"en-US","url":"https:\/\/secure.gravatar.com\/avatar\/d3b6149fb1fb06b36083b7009dbff0af?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/d3b6149fb1fb06b36083b7009dbff0af?s=96&d=mm&r=g","caption":"darko"},"url":"https:\/\/intek-hifi.com\/en\/author\/darko\/"}]}},"_links":{"self":[{"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/posts\/24228"}],"collection":[{"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/comments?post=24228"}],"version-history":[{"count":8,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/posts\/24228\/revisions"}],"predecessor-version":[{"id":24237,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/posts\/24228\/revisions\/24237"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/media\/24229"}],"wp:attachment":[{"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/media?parent=24228"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/categories?post=24228"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/intek-hifi.com\/en\/wp-json\/wp\/v2\/tags?post=24228"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
