Looking for a set to run on my PPI900.4 so they need to be able to handle 145w. Been looking at the Massive RK6 and RE XXX6.5 but no one has any of them in stock. May be interested in a set of Hertz HSK's if the price is right. Looking to spend around $150-$200, but may go up for the right deal. Let me know what you got. Paypal is ready!!
