Just an update on my choices so far: I went with the Denon MC 6000. Eventually, I was torn between the Native Instruments S4 and the Denon, but finally chose the Denon - the build quality, output options, software options swayed me over. Thanks for all your suggestions and advice.
Now I need to decide on a speaker. My plans are to use this for indoor / outdoor events catering to about 100 people. I am thinking of either the JBL PRX612M or QSC K12.
I currently do not have a subwoofer, but plan to get one very soon. Similarly, I am only buying one cab now - and will save up enough money to get a second speaker a bit later - probably by Xmas.
I listened to both and it seems I like the bass response from the PRX a bit better. It seems it is also a bit heavier. However, I liked the fact that the QSC has a built-in fan, and also separate controls for high/mid/lows right at the back of the speaker. At the end of it, I was leaning towards the PRX612. So my questions are:
1. Are there reasons to go for the QSC as opposed to PRX?
2. If no, and the PRX is preferable, then should I go for the PRX615 or the 612? The price difference is about $100. I have read that there is very little sonic difference between the 15s and 12s, so it is better to get the 12s and add one or two subs depending on my needs. Are these solid justifications for getting the 12s as opposed to the 15s?
Thanks in advance for your help.
