The type R's are alright as long as you have more than enough power to feed them. If you are running a 500/4 you arent gonna have enough to push the R's to get a decent sound. You better go with something with a higher efficiency. Check out to find availability for a Cerwin-Vega Vega series subwoofer. you should be able to find one for around $130 , and with an efficiency of over 95dB the sub will be more bang for your buck
