There are several You Tube videos where individuals are ranting and raving how great the JbL's are . Since it's a suitable for desktop use I think I'll go with the Klipsch . ThanksBoth speakers have compression driver horns and the Klipsch is tractrix. When I heard them the Klipsch had better bass response. The JBL sounded really good on the desktop. out in the room I thought the RB-5 was better. i heard them separately so that's about as detailed I would go.
The amp I'm using is a 30 watt Niko , room size is 15x13 with 8ft ceiling .I suggest you to try and hear both pair.
Perhaps you can elaborate on your Room size, Power used, and Budget.
Music flavor and sound restrictions.
Both are Budget level speakers. With decent horns for the money.
Both have good resale, so if clean you can usually get your money back,
When it's time to get better ones.
