im using just two mini monitors (bookshelf speakers) and a velodyne subwoofer. so my moniters have a bass extension down to 50hz and my sub can go from 140hz on down. what should i should set my cross over at for optimal sound quality. I also hear that the best cross over frequency is 80hz on down goes to the sub is this true?
-thanks in advance

My experience has been that the lower you can cross to the sub, the better. There are many reasons for this, but one of the big reasons is that subs don't sound very good in the "normal" part of the bandwidth - the area where you can actually hear placement and the like. The bigger the sub, the worse off this range is. Furthermore, a very low crossover allows you to use the gain (volume) as a low frequency booster. If your sub is active at 80 hz, it just starts to get honky in this range. Experiment with 40Hz - I think you will find it to be better sounding. There is still significant overlap in the 40-50 Hz range to not have a dropout, and you will be pulling the very low stuff away from your mini monitors. This keeps the best part of the range in your mini monitors, which will sound a whole lot better than your sub in the 50-80Hz range.
Try it and see what you like best!

Hi. In my opinion Subs. are only useful for sound effects with Home Theater . If you are serious about listening to music with Hi Fidelity equipment then a suitable loudspeaker with a flat responce down to 30HZ will always be better. You don't need to go any lower as you may hear residual noises in the playback medium.Of course i may be totally wrong and others will disagree and say by using a powered sub you are saving your Amp. from struggling to reproduce the low frequencies. A well designed Amp. will have no problem delivering its continuous output into a specific load at a max. distortion over its full frequency range without running out of steam. It has been built to do this. It is nothing like a surround sound receiver which can run into trouble at very low frequencies.
Sorry if i got a bit carried away grindkin....!
Cheers.

The ultimate answer is to set it at whatever you find to be pleasing to your ear... but as a starting point, I would begin at 100hz, as, even though your bookshelf speakers can technically produce a 50hz wave, the fidelity of that wave from such a small driver would be in question.
Choose your reference sources (Movie/TV, Video game, multiple music sources), get out a notepad and allow yourself a half an hour to test and tune.
Write down the source, the sub setting (volume and crossover frequency) and your impressions of the different sources. Go to much higher (and lower) a crossover point than you would intuitively select and take notes for each of the sources.
You will very quickly know what sounds good to you... then I'll be looking for your answers on Yahoo!.
Best of luck.

90 Hz is actually a very fine crossover point....
90 Hz will take out any 'damaging' bass to your bookshelves and make them VERY defined and punchy..

80 is a really good place to start, you can play with it after that.
