Reply With QuoteIf you have the room, I would go with 2 12's. The twelves will hit lower frequencies and with more cone area produce more sound. I lnpw you have room somewhere in that boat for two 12'sHow do you like the Eclipse 6x9s?
Upgraded the cockpit speakers to Eclipse 6X9 4ways and have a JL 500 amp itchin to get put in for the sub(s) planned under the back seat. It is tall enough for a 12" sub and deep enough for a proper enclosure.
Question is: With the type of 6X9's I have will two 10" subs be better off than one 12" or vice versa and why?

The Eclipse's were really a big step up - thanks for the plan. I am running the amp too hot now so that looks like I'll need to upgrade it later
I am concerned that I may overpower the upper end with two 12's. Am I unlearned here or what? I also don't want to rattle loose any screws either J/K
I am running for Eclipse 6x9s (the same ones you have) and two 12's in my little 18ft boat and it does not overpower the high end. In a boat you can never have too much. And you can always turn too much down but you can never turn not enough up. :wink:
The F3(Frequency response @ -3db) between 10" and 12" subwoofers within most model lines(10w3 vs 12w3)normally isn't but a 1 or 2 hz difference, and a vented enclosure can be designed to hit almost any frequency you want... no real reason to go below 38hz anyway... Like Bill said, the benefit is greater output because of cone area. I think you'd be happy with the 2 12's. Although, Mandelon has 2 downfiring 10w0's that pound pretty hard off a JL2501. Heard a few notes from it last night and walked away pretty impressed.
Knowing what kind of performance you expect from the sub(s) ahead of time is helpful, but RUNNING IT HARD like RB said is always a safe bet...
2....
THanks for all the sage advice. It will be two then.
PS Dont tell the wife - she likes surprises :jawdrop: :jawdrop:
My prescription: Two 12's....big enclosure's...and lots of clean class D power...
for somthing simple you can just take the dimensions of you seat box and then re-build it with two ported chambers on the sides and use the center for storage or you could get trick and build a type of bandpass enclosure and get a little more output out of it just depends on the power you are gonna run????
Ported or downfiring yes, but a 4th order bandpass enclosure is not condusive to being in a boat. Plus you're talking about him finding a driver that will work, and him doing a bunch of math in order to get it correct.
I know of a few downfiring applications that work really well
