Welcome to WBF. First, I think Danley is a member here? Which means if you look him up, you can PM him?
Second, it sounds like you are looking for commercial/club type equipment? There are a few members here with that kind of experience. I do not know what type of system you need (those others here will), but my two cents from experience:
- If you are going to be operating a club, people who club frequently may not know about audio equipment...but they definitely know what they like to hear in terms of sound.
- Back in the day, many of our friends who went out often always knew which clubs had the best sound, which DJs used vinyl, etc.
So setting aside money, it is worth getting the sound to come thru both clear and stupendously propulsive in the bass. It is surprisingly how many people hit a club...and STAY...when the music is good (both choice of music OF COURSE...but also how good it sounds.) Way too many clubs crank with distortion...deafening but with distorted bass or highs that are imbalanced relative to bass n an attempt to help you [sort of] be able to hear lyrics.
If you are playing electronic/deep house at all...there will be information sub 40hz, and i think a system designed to take you there makes a big difference.
two cents.
