User manual BOSTON ACOUSTICS SUB10F

[. . . ] Sub10F In-Floor Subwoofer Introduction In many homes and installations, the deep bass of a powered subwoofer is desired, but often there is not a suitable location to install a box subwoofer. Located below the floor and powered by the companion Boston SA1 Subwoofer Power Amplifier, all that is visible in the listening room is a floor register. Warning: Always turn off the amplifier when connecting the subwoofer and any other components to the system. Installation should only be attempted by professional installers or those possessing skills in construction, the proper use of hand and power tools, knowledge of local building and fire codes, and a familiarity with the environment below the floor in which the subwoofer will be installed. Placement For maximum bass, place the Sub10F so its vent is near a corner or sidewall and is as close to the main speakers as possible. Floor Register (Not supplied) The Sub10F mounts in the floor directly below a floor register. [. . . ] We recommend the use of 16-gauge or larger speaker wire with both the Sub10F and SA1. Service Access If service is needed, the Sub10F's woofer can be removed through the access panel on the bottom of the subwoofer. If there is a finished ceiling below the Sub10F, ideally a door allowing access to the complete subwoofer enclosure, or at minimum, to the Sub10F's service panel, should be left in the ceiling below. 3 Preparation for Installation 1) Attach the supplied gasket to the subwoofer. 2) After deciding on the location of the Sub10F, use the supplied template to check for the fit of the subwoofer and location of the floor register. It is important to check both below the floor where the Sub10F is to be mounted and in the room where the floor register is to be located. Do not use wood screws. Installation Be sure to mount the Sub10F rigidly to the floor joists, as its tremendous output could cause unwanted vibration if the Sub10F is able to move. Be sure the joists to which the Sub10F is mounted are securely braced against each other so that the distance between them does not change and they are not able to move or shift. 2) If any nails are protruding from the subfloor above, cut or hammer them out of the way. Note: If there is not going to be ceiling installed in the room below, it is best to mount the Sub10F after construction is complete. If the subwoofer must be installed while construction in the room above is still in progress, cover the hole for the floor register so that construction debris or liquids cannot fall onto the subwoofer. 3) With the hole for the floor register as a guide, hold the Sub10F in place and use the supplied brackets to mark for screw holes. The Sub10F's cabinet is made of MDF (Medium Density Fiberboard), which can crack if pilot holes are not drilled. 6) Attach the brackets to the subwoofer, and mount the brackets to the joists. Use wood shims, if needed, to hold the Sub10F tight to the sub-floor above. Important: The gaskets on the subwoofer must form a good seal with the sub-floor above. 4 Installation (Cont. ) 7) If you plan to attach the Sub10F directly to the joists using screws, use wood shims to prevent damage to the Sub10F enclosure.
