I've done an ABX with the Insignias being recorded in an anechoic chamber vs. the original sound file and also with a reverberent room simulation applied to the original recording and the recorded speaker. They sound surprisingly good. With a cabinet modification to reduce/eliminate resonances, they sounded audibly better. By "better" I mean that obvious resonance coloration in the midrange was removed by damping the cabinet. It is audible to the point where I could tell with high accuracy the difference between the modified and unmodified speaker. And while the cabinet resonances are not as apparent in the anechoic recording, they become very distracting when heard in a reverberent environment.
All my rambling above might be fine and dandy, but I don't know if these are really available to you, Mike. They are Best Buy's "house brand" budget speaker here in the US, and I don't think BB ships internationally. If they do, then you might be in luck, as they are actually quite good for the price. The off axis response leaves something to be desired, but that is a product of the tweeter placement and the low-cost pricepoint. And besides, if these are going to be speakers that sit on your desk off axis response becomes somewhat of a moot point, as you're not really aiming for room filling, super accurate sound.
If anyone has any questions regarding the ABX, just PM me and I'll explain further, but I don't feel that I need to waste time in Mike's thread to justify and explain my claims.
