This would involve cutting the RCA connector off of the centre speaker from a set of retired Logitech x-530's and wiring the speaker in.
HTX22HDX states 6-16 ohm only on the back, Logitech says its speakers are 4 ohm (i'm guessing nominal?)
Would this kill the receiver?
Is there a way to increase the resistance of the speaker up to 6 or 8 ohms? Even if it's difficult, i'm looking at saving money, not time ;)
