Combining Powered Studio Monitors with Sub

maybe a different approach, but i went with a krk 10s sup to go with my full-range speakers - i set it on a separate on/off monitor switch and did no eq changes to my mains.

i rarely use it (mostly because my mains go down to 41hz, and is that 5-6hz of extra frequency range really worth the trouble of another crossover and balancing act?)- you may find that the crossovers on consumer gear fare quite poorly to even the least expensive of the 'prosumer' market bits like the rokit krk pieces. this thing works despite its pedigree. sadly its' phase options are limited so positioning is critical.

YMMV

 

tbh the money would probably be better served investing in acoustic treatment for your room

 

Check out the gearslutz forums, theres a whole section over there on acoustics...

but to put it really simply, you make a wooden frame and fill it with rockwool


It also depends on the size of your room, you may find that, in a smaller room, subs will end up causing more problems then they solve, if you dont spend the money on a sub or treatment you could look at some speakers that can go down to say 40hz or so anyway and you wont need a sub, again, check out the gearslutz forums, there are lots of knowledgeable people on there who can give you great advice

To answer the original question about getting the sound to all speakers...

i'm using a samson c-control http://www.samsontech.com/samson/products/processors/c-class/ccontrol/ which i got second hand for about £50 it has an output that can be configured for a sub.
