Is that 750 for both of them or 750 per SB3000? I am in same boat as you and about to pull trigger on two SB3000 in black ash for $1500 total…not gloss finish like those, but these one appear to be in near perfect condition.
Following to see what advice you get, but I’m leaning towards sealed over ported. Have a toddler in the house and ported subs are def going to wake him….thought is I will hold onto these for a few years and then sell them and get a big ported one then.
