A:AnswerI also have a different Yamaha receiver. The 5590 is listed as having pre-amp level sub outputs, so it should be compatible with the Klipsch. The only inputs to the Klipsch is a pair of RCA R/L jacks and it looks like your HTR-5590 has only a single RCA output for the subwoofer. If so, I believe you will need an RCA cable with a splitter - single RCA plug at one end and two RCA plugs at the other.
A:AnswerIf your receiver have a single sub pre amp out you'd connect to the L/LFE input on the sub. There are 2 rca style inputs on the sub but the top plug per the manual is the L/LFE input if you only have the 1 pre amp out on your receiver. if you have dual pre amp outs on your receiver you'd connect both.
A:AnswerIt looks like that receiver has pre outs that you could connect to the line level input of this sub. But you have to use Y-adapters to do it so that the pre out still connects to the main in.
A:AnswerThe R-100SW is not compatible with the WA-2 or WA-3 wireless kit. You will need to look for a RCA wireless subwoofer kit to be able to accomplish making the R-100SW wireless.
A:AnswerIt's rated at 150W. Sounds like you are looking at the reference premiere series which if I remember right has twice the wattage as the one I bought which is only the reference series.
A:AnswerAll it takes is one connection. No "Y" connection required. Most receivers advise connecting subwoofer to the Left channel (Subwoofer Output). If you are worried about loss of both channels, check your receiver owners manual to determine which subwoofer output to connect.
A:AnswerThe R-100SW is a powered subwoofer intended to connect to a receiver or powered speaker's RCA Subwoofer output. This subwoofer featured a dual RCA Line Input. You could use a dual RCA (male) - 3.5mm (male) to connect your phone, but you will only get bass frequencies, as this sub only has a frequency response of 32Hz - 120Hz.
