Do you know what JBL is doing with these?
I think sales of the 530 were probably excellent, but they have been out of circulation for a while now.
Are they just clearing out old stock? I might have thought we wuld have seen a replacement by now.
Scottter140 & Pogre,
The Studio 5 series has a great reputation and is one of the best values (especially at the discounted prices). I would expect you to find the sound different, but have a hard time deciding which is better if you compared against something like SVS Ultras. The one place where there is a definite and obvious difference is appearance. I'm not talking the style, that is obvious. The fit and finish of the Ultras is stellar. By all accounts, the fit and finish of the Studio 5 series is a little rough. The plastic outrigger feet are supposed to be a bit weak for their purpose, and look at the drivers in the shot below - obviously, the designers are not trying to make a visually stunning product. On this model, the budget was not increased to make the details look good!
So, knowing yourself (or your friend, in Pogre's case), consider that.
If you like things clean and pristine, the Studio 5XX's are not a good fit. If you have a "utility" attitude about such things, these are perfect!
