I think I just got a good deal, Crossfire BMF 10's

[fox_forma 10+ year member]

Just picked up a pair crossfire BMF's for what I think was a cheap price. I have been trying to research these as much as possible but there doesn't seem to be much info out there. Some people say the older stuff is better and some say newer is better. Is there a way to tell when they changed? The cone on mine looks a little different then the ones on crossfires site but I saw a lot of other pics that look like mine just with no dates. Also I can't seem to find the recommended airspace for these things.

I had a soundstream t5 ported in my ext cab silvy but I just didn't care for it. Wasn't as clean sounding as a sealed set-up so I decided to go with two 10's sealed and I think these will fit the bill. So who has info on these subs???

i have a pair.....had them for like 8 years. they did 146.6 in a full- double baffle band-pass. sorry i don't have the t/s parameters anymore, but they are still the most stout polymer cone 10's i've seen yet.... question is- what do you have powering them?

I havent hooked them up yet but I have a few amps to work with. I have a cadence z9000, Orion hcca250 and a few others. Thos would be my two main choices for now though.

due to impeedance, i think you are going to have to use that hcca to feed them. they really want closer to 1500, but 800-1k will work fine

Didn't see this, I do plan on going to a bigger amp but i was hoping the cadence would be ok for now. They are rated at 400wrms and I understand they can do over their rated power but should the cadence be ok for them. I can run them together at 4ohms or split into 2ohms to each channel. I believe the z9000 does 800wrms @4 and actually rates out a little higher.

Sealed is going to be my main preference but ported is still an option.
