Subwoofer question

[**DONOTDELETE**]

I am also considering two 15's but am in another dilema as to wat the difference is of one port or two ports. Will 2 ports give me more power (bass) or vice versa?

Having an extreme hatred for ported boxes, I would have to just recommend you avoid all that mess and go with a sealed box. I also wonder why you would want 15" woofers when 10's and 12's have a far superior sound. 15's in a ported box are only good for making noise and it's usually not good noise, IMO.

ChuckH knows whats up. Don't use a ported box, sealed boxes sound much better. As for the 15s, 10s and 12s have less cone surface area so you get less flex out of them which produces better response. They sound much cleaner.

If you get two 15's in a sealed box you would have to use a ton of power to have them sound clean. I would personally go with three tens. They would have the same surface area as two 15's but they would sound way more crisp and responsive. Of course two 15's will reach lower but with a ton of POWER.

Im confused?!?!.... sealed? would that be a subwoofer already sold in a box direct from one company? then i guess ported would be component subs put in a box afterwards? is an alpine mrv-1507 (1500x1 bridged) going to be good enough to push the two 15s?

Its not so much the flex of the cone, its the added weight of it. They build the cones out of such strong matterial that it shouldnt really be a concern. If you use a ported box for 15's, then most likely its gonna have to be a huge box(usually 2 to 5cf of airspace for each sub). I guess you just wanna be the loudest & thats why you got 2 15's so trying to talk you into just using one would be outta the question, but that amp you have should do the trick for 2 if thats what you want. Unless you get the box built by a professional, then it will probably sound better in a sealed box. As for the ports, I dunno if 2 are bennificial but I think the larger the port, the louder it gets & the smaller port will add "tightness" to the sound. I may be wrong, but I think thats what a read a while back, I could care less cause Im putting a sealed box in my car.

wouldnt u need a smaller box also if u have seal compared to ported
what do u drive ? how u put 2 15s?
also 10s sound better than 12s and 12s sound better than 15s?

Just to kind of sum up this discussion:

1)Ported gives a good kick to mid-bass freq's, but that is best for SPL, not overall audio quality

2) The bigger the sub (ie 15") the lower it can hit, but you sacrfice some high end, and it's response tends to get a bit sloppy. Also the bigger cone means your pushing more air, means you need a bigger amp to do the same amount of work.

3) People who compete for sound quality are often seen with 2-3 8" subs, people who compete in SPL can be seen with many 15." Pick a happy medium :P

4) On my 240 fastback I'm using 2 Pioneer 10"s. They hit VERY hard (ie: ear drums sore, review mirror knocked outta place) and they sound great. Also they can be used in a rather small box, so they tuck right in between my spring panelling in my hatch, looks like a sweet custom install almost even though I did it myself in a couple hours

5) No matter what, spend your money on a good amp. Distortion killed my previous JBL 10"s

i think that using ported or sealed boxes depends on what u have--hatchback or coupe. With a hatchback, u want to use a sealed box because u can notice the distortion coming from ported ones. With the coupe, i can't hear the distortion of a ported box. So I'd go with that. Besides, especially with a trunk, you'll need much less power to handle the ported box. just my two bits.
