So I have a simple question. What are your thoughts anybody on the QSC K12.2 speakers?
They're good speakers with some really handy features. Your purchase (if new) is far enough into the production that whatever issues existed are likely resolved.
(A good reminder that it's not always best practice to be the first to jump when a new product is developed unless you can afford to be the test pilot and have good support.)
You may however, have over-purchased for your needs. Yes, a 12" driver will give you good sound without subs, but I don't think you had to spend $1,000 per speaker to get a solid sounding 12" active woofer. There are other similar models that would have done a great job for about 1/3 the cost. A lot of the expense is for a discrete DSP that you don't really need because your only program material is prerecorded music. The cabinets are touring grade that greatly exceeds the kind of exposure they will experience in your personal handling, and includes flying points that you will never use.
The entire Kx and Kx.2 lines are ideal for rental and production houses where the job parameters are different every time they go out. The DSP provides short cuts that help reduce the amount and expense of other equipment necessary to achieve a given result. Delay speakers in film/theater, or presentation is such an example. Delay can be set at the speaker along a single line feed, eliminating the need for additional routing, cabling, or even a console.
Your DJ use is consistent and straight forward (literally) just two speakers playing a studio recorded stereo (or mono) source. That's generaly going to sound great on any speaker - including some really good ones in the $300 range (just 1/3 of your current expenditure.)
For $2,000 I would prefer to have seen you acquire 2 active speakers, with stands, cables, covers, and a reliable controller. I think that's something tha was easily attainable. If it were me, and I could return both the controller and these speakers - I would do it, and use the same money to get fully equipped with reliable and application appropriate gear.
