JBL Studio 590

I owned a pair for about 18 months.Yes they are very good speakers for the type.Basically they give you a good taste of what large horn speakers are capable of-a big open soundstage,excellent dynamics and lots of vibrancy and presence .Unlike most horns they measure extremely well  and have very good driver integration so sound seamless.
They need a big room with  lots of space around them to sound their best.My room was really not big enough for them and the bass was a bit overpowering as a result.Which was the only reason I sold them.They sounded superb with my Almarro 318 SET amplifier and I think that is their real attraction-they work really well with lowish powered tube amps.Very few mainstream speakers do.

Curious what amp are you using with the jbl and kef prior and how big is the room?

Thanks. 

I'm currently going to be using an Anthem STR Integrated Amp.  The room is big and odd.. It's connected to a kitchen (open concept kinda thing) that puts my listening position right in a dead spot.

Hey DTX,  how was your shipping experience??

Excellent.  However, I refused the shippment so I never actually took hold of them.  I decided they were too big and impossible to sell.
