Ive owned them both as well as 4350 ect.the l250 will be smoother and is more audiophile like. The woofers can handel Very high current to keep up with the rest of the drivers id go with at least 300 a side with big time reserves. Ive ran 750 watt Crown delta omegas on the the l300. ( Not Summit) and the amp could be driven to rated.
You might want to look at the 4430 and 4435. Thes I clipped the *&^% out of the mono blocks:) the Biradial 4435 are very stable in terms of imaging properly ste up you will snap your neck following the imaging. With the L250 the B460 subwoofer is a natural partner. A nice Sleeper is is the L150 will compare with these systems for a lot less.
