going to go pick up the krk rp10s this weekend...but was just curious about one thing.

since its port is on the front...will there be any issues if things like record crates and what not in front of it? will it really hinder the bass and just cause my entire setup to rattle and shake like no other?

don't really have much room to put my records and stuff anywhere else except for under my desk. kind of a tight fit where my gear is.

Yes, don't have anything obstructing the ports as at best this will make the bass frequencies sound crap and at worst rip your drivers (vacuum on a big movement - seen it done).

If they are for producing (monitors) google equilateral triangle speaker placement or similar.

For maximum bass response, always place all bass cabinets on the floor, with their backs directly against a wall, and preferably in a corner. The lower the air volume within one wavelength of a bassbin (i.e. within about 30 feet), the better the impedance match will be between the air and the bass drivers. As a result, two things will happen. First, the acoustic power conversion efficiency of the drivers will go up exponentially due to the improved impedance match of the low impedance cone driver to the normally high impedance air. Second, the relationship between bass SPL and distance from the cabinet will become more linear as opposed to inverse exponential. This means the bass will travel further, due to the horn loading effect created by a corner made by two walls and the floor. In this type of corner, a bass speaker only has to push air in 90 degrees in each axis, i.e. it is 1/8th space loaded. An 1/8th space loaded bass cabinet will have several times the acoustic power conversion efficiency as a 1/2 space loaded (i.e. on the floor but not near any walls) cabinet. Considering these points, it's clear that you can get much more bass from the same bassbins simply by placing them optimally.

Thats what I was gonna say.

This definitely is the maximum bass response, but also the least accurate, because unless the walls & floor are perfect bass traps, you'll get all kinds of resonance and standing waves, which you probably don't want if you need to hear everything accurately.
More space than the subwoofer has around itself from the nearest wall, the more accurate it will be. The sound will still bounce, sure, but not in huge proportions as it would in a corner.

I found that a damn good low-tech solution for placing subwoofer is... newspaper! Put 10-15cm thick layer of newspaper under your sub, place it on your desk if you can, and you'll get great accuracy of the sub and your desk won't shake that much either
