BTL or level 5?

[Hell-Razor 0]

Well after a lot of talking with Shizzz and screwing up not being able to fix the box in the trunk (and realizing I cant fit the box and the amp and the batts back there) I am thinking I am best to go to a single woofer. Now I was reading around and it looks like a single Fi BTL 15" can be used in a 3 cuft box. I am going to be throwing a SAX-3500D at a woofer by the way so I will be over-powering almost (I think) any woofer out there. But after talking to Shizzz some more he says that he recommends the level 5 12 at a minimal 2.5cuft box. I can do that seeing as the original box was about 5.5-6 cu ft. But wondering what would be best on the smaller box size -- either a BTL or a level 5(or another subwoofer). I am almost complete on receiving everything and would like to get this ordered in the morning (the most important part...hah).

After I design some boxes and look around at some 15's and see if I can reduce the box size a lot I will see what I can do with you guys recommendations. As of right now I don't know what the single level 5 15" woofer requires for minimal space. I believe Shizzz told me 4 cuft but not sure. I was told by a few people (not sure if its the bad advice thing like ///M5 says) but the more power a sub has the smaller box is needed. Is this true? And I have been reading on the level 5 woofers and everybody says its mainly a spl not a "music" playing sub. I don't think this is true but I could be wrong.

My main concern going with a btl (12 or 15) and a level 5 (12 or 15) is that i am throwing almost 75% more power at it than what its recommended for. I also know DC subs are nothing to joke around with either. So your guys .02 cents is well welcome here.

just found this for specifications, that will help a lot. Im thinkin I am going to stick with DC unless someboy has a good reason to go to something else. This says they can peak 20k , daaaamn

setting the gain on your amp with a DMM, you can have the power you want.

If you don't want to push your sub with 3500 watts, you don't have to do it!!!

Regarding the subs, I have never heared them, so I can't tell you nothing. I am not into the spl side!

I would take a 15" Xcon (and maybe run the amp at 2 ohms), or 2 12" Xcon ; and a good ported box.

Good luck!

Yeah I decided to listen to him and stick with the level 5...now I need to find a mod to delete this post cause I feel like even more of an idiot

[shizzzon 461]

no, i'm sure they only delete a post if it gets out of control or just gets filled with completely useless information.

///M5 is right about the more power a sub receives outside of it's recommended box volume the smaller it needs to be for musical purposes.

Now, the Level 5 15 needs to be in a box anywhere between 3.5-5 cubes NET.

look at thorshammer build. He uses custom made level 5 10s ran over 5kw for music and handles it for moderate durations just like your ears.

ask him what they sound like, he would know better than i would.

that 20kw peak rating consists of many things to be able to do that.

I'm sure there are other subs, hell even the level 4XL may even be able to handle that power amp-rated, not physically.

short bursts can always handle more power than long durations.

You'd be surprised how much power some people will run to a single sub.

Mach5 even tested the new MJ18 to handle over 14,000w for a short burst i believe and it's more of a Home Theater oriented subwoofer than anything else.
