Okay, I don't understand exactly what you say technically 8 ohms, 6 ohms, etc, but I understood that Denon x2100 is good receiver to use with 530. Thanks. Do you know the answer for the blow question I posted?
Is
LSR308 better than JBL 530? Provided if I can buy JBL 530 for about the same price $440 per pair, still
LSR308 is better? What is the difference between
LSR308 and 530?
For me and home theater and music use - I prefer passive speakers with a receiver.
The Studio 530 is passive, because is has no built in amp.
If I was mainly doing 2 channel music and home theater listening - then I might
consider the LSR308 - which is an active studio monitor, with a built in amp.
JBL did compromise on the LSR308 cabinet to keep the cost down
You do not need a receiver with active speakers - however, you can use one as a
pre-amp - or just buy a pre-amp. I am not one who would use 5 active studio monitors
for home theater - however some might do it. You would have to plug in all those 5
monitors into electrical circuits.
With the passive speakers it can be easier to set up - and you get bass control
for your subwoofer with the receiver.
I am sure the JBL LSR speakers are decent - however the Studio 530 for me is
a real nice unique speaker, that can take some power and has strong cabinets.
It is all about what floats your boat and what you want to toy with.
