Morning all!

I am working on a subwoofer design for two different projects. In both cases, size of enclosure is no issue. I was wondering which characteristic you would say is more valuable when trying to achieve a higher SPL with the same amplifier driving? I have a choice of a 12" driver with 93.4db 1w/1m and the same brand/ model 15" driver with 91.8db sensitivity.

The twelve inch will be able to work with about 4 cubic feet vented and the 15" could have up to about 6.5 cubes. Of course I have about 8 total feet to work with so I can get creative, but I am not so much interested in the box design criteria first as just simply which would be easier to get the desired results with? Higher SPL or Higher cone area?

Thanks,
Robert

Thanks for the info Dan! I didn't realize they had it set up that way and I don't want to know how you guessed which subs I was looking at. lol.

OK So now I have decided that due to the very limited power I will be running, I am going with the 15" classic woofer.

It's for a car install and I don't expect a whole heck of a lot in the SQ department, but having some flexibility with it will be nice. I am going with a very large, vented enclosure. Standard car box I suppose, but I have enough trunk for the box and 3 dead bodies so I am going to take advantage of it. It is an interesting install that I should be able to finish next weekend. I will take pics so everybody will know what I am up to.

Thanks for the help. Does anyone have an opinion on the classic woofs? They are about $40 cheaper and there is nothing wrong with that in this "budget" install lol.

HI Dan,

Well it sounds like a winner in this case. It is a car and the amp is 2 ohm stable so I will use the 4 ohm version. I did the math and the box is just over 5 cubes and will be tuned at about 35hz. I might go a bit lower. Maybe 30hz. I can do a 20hz rumble filter to protect it too so hopefully no serious excursions below tuning. Can't wait to get into it.

Unfortunately my wife wants me to finish the living room rather than start any other projects. Even more unfortunately, I haven't the skills to do what I want done in the living room yet. Learning curves take time lol. Maybe I can sneak this one in as a xmas gift anyway!

Take care,
Robert
