15'' Rl-s Vs. 13w7

is there anyone here who has had experience with both these subs and if so which sub performed better in the following categories SPL and SQ?

i would take the rls cuz its like 400 dollars cheaper and i heard sq and spl are still pretty awesome

i have the 13w7 already i was just looking for something with just more spl with out losing to mush sq

The RL-S is a HT woofer anyway. And I dont think you can buy the 15" version anymore because of problems //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

x2, the guy at soundsplinter told me that if i was lookin into using it a car audio application, that i should shy away form that and use 2 RL-p's instead.

put more power to it, or port it.that Dub7 should get **** loud.

I've heard the RL-S's need huge boxes, and are very inefficent.Coming from the owner of it.

SPL department I'm very confident the W7 would win......

Assuming you had the power to push it, the Rl-s would have more output. Simply has more displacement. It has about 30% more displacement, which means in a sealed enclosure it has to potential to get ~2db louder than a W7. Problem that arises is getting enough power to use all of that excursion the Rl-s has.

But, as was said....the 15" Rl-s is presently not shipping. Plus they are inefficient as hell and need decently large enclosures. IMHO you would be better off with two 15" Rl-p's than a single 15" Rl-s. I had 800w on a single 15" Rl-s and on a single 12" Rl-p....and off of that wattage the Rl-p had quite a bit more audible output.

talk to 80inches about them needing huge boxes, from what hes done math wise they dont need it.

talk to 80inches about them needing huge boxes, from what hes done math wise they dont need it.

Qr = Qtc/Qts

Vr = Qr^2-1

Vb = Vas/Vr

1.2/.953 = 1.259181532

1.259181532^2-1 = 0.585538131

85.37/0.585538131 = 145.7975075L

145.7975075L = 5.14cuft

So, it needs 5.14cuft to even have a Qtc 1.2 sealed (which is high). That's large, especially for such a high Qtc value, and especially when you compare it to other 15" subs.

To get a Qtc of 1.0 with the Rl-s, you'd need a 30cuft enclosure....or basically infinite baffle. That's a Qtc value most other 15's can achieve with an enclosure in the 1cuft region.

That's not to say the Rl-s is a "bad" subwoofer.......but yeah, they need large enclosures //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

thanks guys that what i needed to hear

to be honest..heres the conclusion igot from messing around with the rl-s12

and this applys 2 the 15 as well

but the reason y people r saying the rl-s needs a huge box.becuz the bigger the box the flatter the response....but what i notice about those subs is....they can play in a small box its just that they will peak at a high freq.

now from my calculations..one rl-s 12 has the potential air displacement of 2 mojo 15's....thats alot of air movement 4 one sub

the 15 has more air displacement obviously...i'm not shure in comparison to what i havent calculated that but i' know its more that 3 mojo 15's

as far as output...in a box tuned to 40hz...i was told(from a very very reliable source..someone who actually bought and tested the rl-s15) the rl-s 15 has almost as much out as a brahma extreme.....and thats alot of output..

the rl-s 12 can easly do mid 140's in a low tuned box..but thats at a high freq between 40-45hz....on the new tl mic it did 140 at 34hz...and thats pretty good 4 one 12 off a stock hu and 1300watts..and a 2.5cube ported box tuned at 28hz

Yeah, but how much power will it take to get it to move that much air in a smaller box //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif You'll probably fry the sub before reaching xmax //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

2.5 isnt that big of a box
