- Page 2 When designing systems with W7 drivers, it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver's capabilities. The power levels listed in the above chart represent continuous (RMS) amplifier power per woofer and assume that the user will regularly make full use of that power without drastically overdriving (clipping) the amplifier(s). Make sure you factor system impedance and the total number of subwoofers into your calculations.
- Page 4 W7 Mounting Guide Please review the mounting procedures thoroughly before attempting to remove the speaker from its shipping baffle. The W7 mounts like no other speaker and care must be taken to follow these instructions precisely. Step 1: Your Tools...
- Page 5 W7 (picture 6a). The 13W7 (not shown) has dual voice coils and must be wired with its coils in series or in parallel. Once the speaker is wired, gently lower it into the enclosure (picture 6b).
