just like to say hi. hope your happy with your axiom speakers. i run the m60s with three qs8 and the vp150 with a vtf3 mk2 hsu sub. the sub blends in perfect with axiom speakers. Also if your after heavy tight bass its great very nice sound no boomy bass. its sound is very clean. it gives you two options either you can keep one port pluged for lower harder hitting bass or go with both open to get clean bass at very high levels. i keep one port plug for the simple reason it would shake my house apart if its to loud. hope you like it.
