The most similar sub from the last series to the EP175 would be the AX500. The power levels are similar and they both use a 10" aluminum cone woofer. The EP175 has the vortex porting, which was not available in the last series, and eliminates port noise. The EP175 is front firing as opposed to rear. The ASW cabinet design is not used in the new subs because the advantages to this design are midrange improvements which do not affect the subs.
