I ran my SVT 4x10 HLF with a Hartke 3500 for almost 2 years. Everything to small indoor gigs to pretty good sized outdoor gigs, two guitars, a drummer, two singers, and a keyboard player. Sometimes didn't even use P.A. support outdoors and never had to turn the amp up past 5. I guess it all depends on what style of music you play, how big the band is that you are playing with, the size of the venues you plan on playing, and a few other factors. I need more info. to give you a better opinion.
It would be the other way 'round, Can the SVT410HLF handle your 300 watt power amp, and the answer is yes, that cab is rated higher than 300 watts.
I ran my GK 800 (300 watts at 4 ohms) into a 4 ohm Ampeg SVT 810 for many years. Never lacked for volume.
