First, JBL says the monitor handles down to 43Hz, which is a lie/fib, if you consider the low frequency published spec should be set at where the bass has fallen off by -3dB, which is industry standard. Monitors with 5" drivers just don't perform at -3dB at 43Hz. It's just physics. That 43Hz spec is likely a -10 or worse falloff at that frequency. Since you use bass guitar in your recordings, that monitor will not give you a correct playback below about 75Hz or so in terms of amplitude.

Second, it has a rear port. If you place your monitors anywhere near a wall (towards the back) you are going to get another bass frequencies anomaly - an inaccurate and mushy exaggerated bass response.

The two will tend to cancel each other out at least in terms of amplitude, but the lack of accuracy will be magnified.

Of course, this is not the end of the world or anything. But it is quite possible that you will end up replacing the LSR305s with something else down the road. Better to buy once, not twice.
Here's a frequency graph link:

This one's a little easier to see: http://noaudiophile.com/JBL_LSR305/J...305_Flater.jpg Seems to be a 4dB peak at 50Hz, and 3 dB fall off at 43 Hz.
Here's a review from Sound-on-Sound:

Cotten's got a budget, not sure why people keep insisting on $1000+ monitors for him!
