Unless you are rocking a super duper cartridge and arm, your system is unlikely to produce anything below 30Hz. M80s will get you close and M100s will definitely reproduce even lower.
Do you really need the center? Maybe you can answer that by experimenting with a v4 front when you receive it.

Bass sounds as it should, maybe a tad light.
I ran HT duties without a Center Channel for about a year, I doubt the V4 M80 would make me want to go back to that... don't know until you try I guess. The VP180 is a great speaker, possibly overkill though.
