I think you maybe getting some odd advice.
A subwoofer needs only one amplifier but that amplifier needs to work hard (lots of Watts) to get the the big drive units to shift a lot of air. The amplifier only needs to be flat upto about 100 Hz or so rather than 20kHz and this helps a lot in getting lots of cheap Watts. Conclusion: active subwoofers make far more sense than passive subwoofers. £100 is not really enough but for £150 you can buy an OK active subwoofer. For example: http://www.behringer.com/B2092A/index.cfm?lang=eng but there are others around this price and this is not particularly a recommendation for this speaker. You can download the manual from the web page and it tells you how to connect the subwoofer for both stereo and multichannel use. Namely, run a cable from the preamplifier output of the NAD to the subwoofer input and a cable from the subwoofer output to the power amplifier input of the NAD. Note that the subwoofer will filter the bass from the signal sent to the power amplifiers of your main speakers which will enable them to effectively play louder and cleaner. There is nothing getting in the way of how the NAD drives the KEFs, the volume control on the preamplifier works as normal although you will have to adjust a knob on the subwoofer to trim the level between the subwoofers when intially setting it up. You may also have to adjust one or two other things when initially setting up as discussed in the manual. Whatever, this is the "proper" way to do it. -- honestguv ------------------------------------------------------------------------ honestguv's Profile: http://forums.slimdevices.com/member.php?userid=13734 View this thread: http://forums.slimdevices.com/showthread.php?t=40177
