After enjoying my Boom recently with a recently purchased ebay bargain subwoofer (a Jamo Sub 200) I now have to retire the subwoofer as the Boom takes its rightful place in the bedroom.
Rather than waste a nice bit of kit, I was wondering if it can be used with the Squeezebox 3? My current setup with the SB3 is quite simple - a couple of Adam A7 active speakers. Is there a way for the SB3 to also feed the Jamo Sub like the Boom can do so well?

Squeezebox 3 + active speakers... + subwoofer?

Answering my own question here, but I guess I could use a Y splitter from the phono/RCA outs of the SB3? The sub has a crossover so I'm guessing that it would cut off everything above say 150Hz. As the sub has left and right inputs, would it make sense to use two Y splitters to feed the Adams and the sub on each channel, or would a single feed from one of the channels suffice - assuming that such low frequencies don't have any significant stereo separation?

What are the possibility's of the sub ? Does it have a right and left rca input ? if so use any Y splitter cable or solder your own.
If it has only one rca input (intended for the sub out on HT amps etc)
Then you have to think about an active filter or pre amp with active filters or similar but i'm a little clueless about that.
There is digital filters/processors in every price range ? but the pro audio folks here nows much more than me. You can probably go to your local music equipment store (not your hifi dealer ) and look at some surprisingly well priced stuff from the likes of behringer who are popular among amateur artists or really expensive pro gear too.
But i'm out of my league here others may have solid product recommendations.

he he.. writing to slow again :-) right and left input = problem solved make an y splitter.

If you have two inputs you should use them.
There is not exactly the same bass info in both channels it's stereo ! so using both L & R should give you an combined mono signal for all bass for use in the sub.
Older recordings is mostly mono in the sub bass (so i've heard), mastering decisions, for cutting it on vinyl.
the sub does it have any rca out ! that would make it even better, but thats rare.
I would experiment with XO frequency if you have no high pass filter for the Adam A7's you might want to filter where they naturally rolls of, so you don't overlap to much

The Adams have tweeter adjustments of +/- 4dB, as well as shelving filters of +/- 6dB.
In theory the Adams can cover a 46Hz to 35kHz frequency range, but I think those specs are ambitious. They certainly sound very nice, but I think a subtle use of the subwoofer would help for my style of music.
I guess my initial query was whether the SB3 can do the clever things that the Boom is capable of - i.e. splitting the low frequencies out via the headphone output, but I suspect that it doesn't have the DSP capability built in. No matter - I see that the y splitter option should give me what I'm after once I've trimmed the various speakers. I'll go with the two channel input to the sub for now and experiment .
