The key to great bass is more to do with the number of subs than anything else. The quality of bass that can be had from 4 or 5 subs for a total cost of around $3k is such that it is the one thing you can do and be happy for life and yes on that budget if you do it right. https://systems.audiogon.com/systems/8367
You can do it either with individually powered subs or multiple subs powered by an amp or a combination of both. I have both. It is awesome. Best bass I ever heard. By far. Not even close.
So get whichever ones you want. Just plan on getting to four, at least. Then your main decision is do you want great bass now with 4 moderately priced subs or would you rather get 1 or 2 now and add more later?
