Which components in a sound installation are likely to have the greatest effect on sound quality? Is it speakers? The amp? Where would you throw your money?
The room has a very high ceiling and seats around 100 people. The system was installed last year and some components are cheap.
The mixing desk is a Yamaha mg166cx which we have had for many years. The speakers are 2 x Pulse PVS15 15" Passive Speakers, the amps are W Audio EPX800 (2 channel 500-700W).
Edited for clarity.
