Running a subwoofer from a stereo amp
Discussion
Hi,
I have a denon 720 amp and want to use it to run 2 small speakers and a sub for home cinema. So DVD and sky box outputs into amp, amp runs speakers and the record output runs a sub via rca leads. Ordered 2 book shelf speakers and a Yamaha YSTFSW050 sub that fitted nicely in the cabinet.
The Yamaha sub inputs from a single rca lead so I cannot connect it to the left/right outputs that the amp has. I see 3 solutions:
1) connect it to one output only, bass frequency doesn't tend to have 'stereo' quality.
2) buy a sub with 2 inputs, a fair few have this.
3) buy a sub with high level inputs and use the spare speaker terminals on the amp.
Does anyone have any other ideas please? I was expecting this to be relatively straightforward based on my car stereo knowledge I gained as a youth....
Thank you.

Have a look on BK Electronics website. They are an internet direct seller, but they did OEM for some other more well known makes IIRC.
You could start at the Gemini or the bigger XLS200, moving up to the XLS400 or Monolith depending on budget and size restrictions. AFAIK they all have high and low level input options. I've owned an XLS200 for about 8 years (still use it in my conservatory set up) and I did have a Monolith for about 6 years and had to spend considerably more building my own subs to get a significant improvement, so they are very good value for money.

Another vote for BK. Plenty on eBay paid £100 for a mint Gemini. Take a while to get the setup right. Once done you forget its there till a bit of real bass kicks in.
PS do not under any circumstances put a sub in a cupboard. It will sound terrible and rattle like mad. Bass at low frequencies isn't very directional and it can be placed away from the main speakers as long as the cut off point is low.
