Sub Crossover Settings Help

[pete321]

I'm using a Mk1 REL Q150E subwoofer soon to be connected by low level to a Yamaha DSP-Z7 with Proac Studio 140's and Studio Centre at the front of my setup. I'm not sure what the best configuration will be for the sub crossover given that the Studio 140's are rated at 25hz and the centre at 35hz.

Taking into account the subwoofer I'm using on depth setting, would it be better to set all fronts to large and not use the sub with them, or large for the Studio 140's and crossover at 40hz for the centre, or maybe to use the sub for front L&R and centre at either 40 or 60hz crossover. Thanks for your thoughts.

I looked at buying a Z7 and seem to remember from my research that the advice given both by owners and dealers was to use 'small' for pretty much all models of speakers.

You can find a comprehensive guide to the setup on the net LINK . The general consensus is to keep your crossover for all speakers with 20hz of eachother to balance the sound. I would get hold of a SPL meter and a copy of Room EQ Wizard and tweak away to get the best out of your new amp!

The thing to remember is that although your speakers go low, the sub will do it better. I would set the speakers as small and have the crossover at 80hz. Otherwise, you won't get to hear it's real potential.

I suppose I'm thinking about the age of the sub. I know the Mk1 REL Q150E was a 5 star WHF award winner, but I don't know how it compares to modern subs, and my Proacs.

It will compare extremely well - I'd agree with the idea of setting the crossover point to between 40Hz and 60Hz, and seeing which you prefer.

I've still got my AVR600 at the moment which only gives you the option of setting one crossover setting for all speakers. As my rears are KEF KHT2005's, this is set at 80hz. I tried experimenting by setting all speakers to small so the sub handles from 80hz down, but I had significantly less bass in the front L&R's. I've checked the sub volume using a sound pressure metre and it is OK. It seems odd as most seem to let the sub take on some of the duties of their full size speakers in a surround setup.
