FI Btl n2

[Zarate76]

So I've got a pair of btl n2 18s and was wondering if they'd be fine on crescendo 3.5k each wired down to .5 for burps and probably wire up to 2 for daily?

Someone local to me has 2 of the 15s wired at half for a daily in a 6th order doing 52s.

Depends on the coil honestly. Most highend 3"coils like 2500-3000 daily.. that's about there limit. Unless you have a huge 8 layer 70+mm coil.

I'm not sure on the full specs on the coil but I know they are fully loaded with the flatwind coil and all that good stuff. Theyd only be down to .5 for burps and up to 2 for daily

I would do half ohm daily.

Those woofers are designed for burps but I'd imagine they could take a clean 3kw.. you can strap them at 2ohm for daily it will be fine..

I thought the n3s were more built for spl and n2s were more ground pounded oriented? I guess I'll give em a whirl and see how they take it.

I could be wrong money. It's been a few years and they might be more of a street beat. You have any tech info?

What kind of power is he running?

 

[Zarate76]

I would do half ohm daily.

What kind of power your local guy putting to them though?

I'd say they are abit more of an spl driver but with some tuning should pound daily.. I would go much more than about 3500 and even then make sure it's clean.. very low mms decent motor strength. I'd say try a flat wall with them in 5.5 to 6 tuned to 34-36.. they will do nicely 6th oder but unless you go really big and tune really low it's gonna play from 34-70 nicely. If yo uh want abit more low end do a flat wall with a shitton of Port area..

I was planning to do a flat wall drivers side port or a 6th but I wasn't sure about the sixth. I'm gonna talk to a local who builds boxes and what not about how we could do it

I may end up getting something else that's does a little bit better on the low end but we can see what we can do with them
