Posted July 12, 200916 yr What do you guys think would be louder(To the ear)?A 12" Havoc 1.7^3 tuned to 33hz Portedor A 15" Havoc 1.7^3(or more) Sealed?Each with 1000 Watts RMS. Edited July 12, 200916 yr by tech2332
July 12, 200916 yr the 15 because you would be starving the 12 for airspace. When putting a sub into a tiny ported enclosure, it somewhat responds like a sealed enclosure. Whatever the box is tuned to, it won't peak for several frequencies above it's tuning instead of just a couple. The smaller the box, the longer it takes to peak...

The smaller the box, the longer it takes to peak...Ascendant audio recommends 1.5 - 2.5 CF ported for a 12" & 1.5-3.0 CF Sealed for a 15".Both of these recommendations seem small to me but I guess they just like small enclosures. Does your response still apply?
July 12, 200916 yr I think the 12" would be louder on the mic. But the 15" would have a smoother frequency response.

Does your response still apply?I didnt know they recommended that low..Still yet, fact is, even if u compare 1.5 to 2.5, a 1.5 box would take longer to reach it's peak.... which would act somewhat like a sealed box.Like KU40 said, the 12 would most likely be louder on a meter because it would have to peak sometime yet the sealed box would be more consistent and more ideal for the space at hand.
