Hey Chief, been a while with no response I see?!

I recently got myself a pair of KRK VXT6's, I believe they're the next model up in quality from the Rockits.

I run my X3 live into a POD Studio UX2 sound card then to the monitors and everything working together sounds absolutely fantastic.

Before I found the VXT's on ebay for dirt cheap, I was hell bent on getting a pair of Mackie MR5's. I went down to my local music shop and listened to as many monitors in my price range I could and each time I kept asking to hear the Mackies again cause for such a small driver, they pumped out ridiculous bottom end which as a metal musician, that put a big smile on my face, very surprised with what I heard for such a small speaker.

Just checking on ebay then, I saw an average price for Mackie 5's are around $350.

Whereas a pair of KRK VXT6's were around 8 or 900 (US).

So for around your price range (maybe a touch more) I wouldn't skip past listening to a pair of Mackies. All personal taste of course but I thought that Rockit 6's just didn't quite have what the Mackie 5's did.

As for your other question about setting em up from the back of a sub, unless it's a damn good sub that you definitely want in the chain, I personally would leave it out.

In the end, you've always got a massive EQ on the X3 live with the tone knobs of whatever amp your using and for general music playing, I know alot of people will tell you to not have any EQ running in your media player at all and to just listen to music flat as the recording intended. I use winamp to play music and I do have a slight bit of EQ going, a little bass with minor scooped mids and I honestly think that what i've got suites the music that I listen to.

If you want to get the bass rumbling stuff on your desk, you can easily do that with a bit of a fiddle with EQ's in the X3 and winamp, so a sub I think would be overkill.

With monitors having such a wide sweet spot, I found that the lightest change in EQ settings made a big difference.

I haven't been at this for too long, i've only had my X3 Live for about a year and my monitors for about six months, i've been playing guitar for 15 years but only now am I really starting to smile with all this set up, X3 Live with monitors sounds UNREAL and as you know, there's just a massive arsenal of sound possibilities to discover.

So my advice is do it! If you can afford just that little bit more than what your thinking now, you won't regret it.

I will say, i'm no expert at all but just having all this awesomeness at your fingertips opens up a massive world of.....well..... just plain awesomeness.

Good luck with it Captain
