Those things have huge drivers and are probably too big for a lot of rooms. Unless you (and your neighbors) absolutely want to have that thumping sound and you go out of your way to kill unwanted bass reflection you're probably better off with the HS5 or something similar.

8" is not a huge driver. The point with these is to avoid the need for a separate subwoofer for most program material.

It's the biggest model in the Yamaha monitor series and if you care about bass that much you probably also want a subwoofer ;)
