Cross-over conundrum

[F G Evans]

I have a set of Tannoys fx5.1 and a yamaha 650 amplifier.

I need advice on the ideal cross over setting on the amplifier to get the most out of the tannoy system.

The subwoofer has a frequency range of 45 to 140 whilst the satelites go from 140 upwards.

The amplifier cross over however does not have a 140 cross over setting. the closest settings are either 120 or 160.

Therefore would would the best settings be to ensure i get the best out of the system. Or would it not make any difernce. My thinking is that if i set it to 120 i will be lossing the range from 120 to 140. Whilst if set at 160 i will be lossing the range of 140 to 160

Someone recomended setting the cross over to 160 and setting the amp to "both" so that the subwoover and the satelites get the low frequency settings. They also recommended setting the speakers to "large" rather than small which they are.

Can anyone offer any advice on this.

Why not set the crossover to 160 you your sub and 140 on the amp. So the sub only gets frequencies upto 124 given to it.
Also having your sub on 160 and your sats at 140 just means that 20hz crossover will be reinforced, and infact your speakers might not in practice go down to 140 so the only problem with having you sub set to 160 is if you can hear it directionaly. Otherwise there is no problem having set at 160 imho.

My sub does not have a seperate cross -over setting and the amp itself does not offer a 140 hz cross-over only a 120 or 160 - hence my conundrum.

I would say just leave it on 160, unless you can directionaly hear the sub I would. DD has bass managment which means it takes lf sound that the little satelites can't produce and gives them to the sub, the theory is that the sound will appear to come from arround you rather than the box in the corner.

Try listening to it on both modes and see which one you like as the right answer is the one you like the best. If you can't tell the difference then don't worry about it.
