Which is better for a DBA (Swarm); powered subs or unpowered?


I want to start building a swarm (starting with 2 subs), on a budget.  Starting with $1000, am I better off buying two used powered subs, three less expensive used powered subs, or a subwoofer amp (eg Dayton SA1000) and two (less expensive) used unpowered subs?  What is the advantage of having a discrete subwoofer amp?  Room size is 13'x22'.

Do you not have to adjust the phase of each sub independently? I wouldn’t think that with four subs in different locations, possibly pointing in different directions, that you would want the same phase or even the same volume levels across all of them equally...

I gather that with the dayton amp, you aren’t able to adjust each one independent from the other (?)
