Will These 2 Klipsch Subs pair?

[ElCid79]

So I will spell out my HT setup.

Marantz SR7001 (as a preamp)
NAD T955 Power amp
Klipsch KF-28 Icon 8'' mains
Klipsch SF-1 Surrounds
Klipsch SC-1 Center Channel

I have an older Klipsch KSW-12 Synergy series subwoofer from the late 90s, that has served me very well. On this latest BF I managed to snag the Klipsch 12'' Reference Sub R-12SW for about $150 using some store credit.

Should I just ditch the old Synergy, or run a dual sub setup?

Some stats.

  My receiver only has one subwoofer output. So I would need to run a Male to dual female Y-Splitter, a cable. Then a single female to two male y splitters (I don't think this part is necessary, as both subs have a LFE input, but I have always run a splitter on my subs.)
