Introduction
Reviewers at AudioRevolution.com literally fight over who gets the next Linn product for evaluation. The reason is simple: they manufacture ultra-high-quality, cutting-edge A/V components at the very top of the industry’s price scale. Linn Products is located on the serene outskirts of Glasgow, Scotland, where they develop, design and, even to this day, manufacture virtually all of their products in-house. Linn feels that this is the only reliable way to control the quality of the finished goods and ensure that their customers receive the very highest-level ownership experience possible.

It all started some 30-odd years back when, in the vision of their founder, the LP12 record playback system was born. This was during a time when few knew or had the vision to see the benefit in perfecting the source component. Previously, manufacturers focused on other areas that they felt were more influential to good sound, like amps and preamps. We all know our systems only sound as good as our source and the marketing behind that is mainly the work of Linn.

The Linn Sizmik 12.45 is a 12-inch powered subwoofer designed to complement higher-performance music and video systems. It physically measures 16.5 inches in height, 17.7 inches in width, 17.1 inches in depth and weighs a solid 61 pounds. It reproduces frequencies from an impressive nine Hz to 220 Hz and is available in black, cherry, maple and white finishes at a retail price of $2,995.

Features
Finding the right subwoofer for your system can be a daunting task. If you step back a few feet, they all look pretty much the same. Take a closer look and the differences are vast. The Sizmik cabinet is constructed from dense MDF plywood, which is heavily braced and feels notably solid. The cabinet has a separate cavity to house its internal 500-watt RMS (1000-watt peak) internal amplifier. For connections, the Sizmik has stereo line-level audio in and looped outputs, RCA line-level high-pass outputs, RCA phono high level four mm inputs and a removable power cord.

To minimize power consumption when idle, the Sizmik defaults to a standby mode after several minutes and returns to power mode when it senses an audio signal. There is a simple, single-digit LED display on the rear that displays the operating mode being modified. There’s a small button that, when pressed, toggles between the modes and an up-and-down button for adjustment. Adjustment features include the following: External high-pass frequency adjustment from nine to 220 Hz, in nine different intervals, Internal high-pass frequency adjustable in nine increments between two and 44 Hz, internal low-pass frequency adjustment in three increments (50, 80 and 120 Hz), as well as a “no filtering” mode. Additionally, the Sizmik has two different gain modes, coarse and fine, allowing you to achieve a finite volume level. It has a phase mode, allowing either in-phase or inverted-phase adjustments. The Sizmik also has bass equalization, allowing for either +3 or +6 adjustment.

Overall, the Sizmik has an impressive amount of connections and adjustments. My only complaint is that the phase control was limited to either in-phase or 180 degrees out. I prefer variable phase adjustment. Also missing from the Sizmik’s list of features is room correction. Some subwoofer manufacturers like Revel, Sunfire and Velodyne are now offering a room correction feature to their subs priced at or below the price point of the Linn sub. This is very intriguing, as this feature can virtually eliminate the torture of trying to get a sub to perform and integrate well in your room. In my case, the Sizmik sub was professionally set up and performed at its very best, along with my full-range Revel Salon loudspeakers.
