hi there guys, i need a little input. I am going to be buyin a system on Friday. Im still debating weather or not i should go with a Kicker L7 15", or a RE SE series. Both will be taking the same amout of power, 1000W, 1500 peak. what do you think would hit louder? I know kicker has a generally hard hitting deep bass, when it made my SQ alpine Type X look like nothing. any opinions?

by the way, the RE SE will be 12"

what about a L7 12? if you need one i got a few only a few weeks old.. pm me if interested

check both of the speakers effeciency or spl. the one with the higher will help you in deciding and you will get more dbs per watt you throw at it. the kicker has an effeciency of 89 db at. 1000 watts it would produce 119 db without the box and in a car and all that other crap. the RE has an effeciency of 88 db and with a 1000 watts it would produce 118 db. so its pretty close and some people wouldnt mind the extra db or two. another factor is its effective radius or cone surface this will move more air= more pressure= more db. The RE has an effective area of 810 sq in or 125 sq in and the L7 has an effective area of 972 cm2 or 150 sq in. In my opinion they are both excellent brands but if you want to get the best bang for youre buck without sacrficing performance go with the L7. these are both in the 15 and the numbers are still higher in all sizes for kicker.

thanks alot for you're response. so thats 1 for the kicker. I've heard kickers play before, because i had one, and my friend has 2 l7 12's in a denali. i find it to be a more kind of "flat" bass, not tight like 2 10's per say. just that i never heard a RE play, so im wondering what exactly i'd get if i went with that.. thanks!

When you decide what you are going with let me know and i can give you more help with youre enclosure if you need it

I've heard both play, they will both pound. I sell RE so if you want to check it out let me know.

If i were you i would not get the L7 15". I had 2 of them ant they did not perform well at all. The 12" version is way better.

However I would choose the SE over the L7.

Just to play the Devil's Advocate for a bit...

Efficiency for a subwoofer is a really tough thing to make comparisons with.

1. Efficiency in a subwoofer system (which includes the speaker and the enclosure) is highly related to the enclosure you use.
2. Hoffman's iron law is a consideration in both the speaker and the enclosure. Given three options (efficiency, bottom octave performance, and enclosure size) you can only keep two. In the days of mega-watt amplifiers at low costs, it might be better to sacrifice some efficiency to save some room and still get good low end performance. Mind you, if you're going for high SPL, high efficiency is still a good thing, but normally subs designed for that give up the bottom end to keep the enclosure reasonable and output high.
3. Published efficiency is a very skewed specification. Some companies measure at 1W/1m, some measure at 2.83V, some measure anechoic and some don't. If you're targeting efficiency as a key to your speaker, you're probably better calculating it based on the other thiele/small parameters.
4. Efficiency (being a low power measurement) matters very little once you've run into power compression.

On the topic of surface area (or, more specifically, the effective piston area), high Sd is a good thing, especially in a ported enclosure, but a small Sd can be over come by long stroke, especially in a sealed enclosure. Just be sure to consider both sides of the coin.

Personally, I highly recommend the SE. I have owned one and sold it; I think I'm going to take a trip and grab another.

if you want spl, why would you even select an SE to look at...
