700 watts, now what subs?

[thevic24 5,000+ posts]

So due to low power, a single 12 or 15 would provide more spl regardless of less cone area?

Depends

one really good 12" sub designed for that power could out do 2 lesser 12" subs.

Efficiency and proper enclosure will play a large part. A 15 has an SA of 177' date=' 2 12's have an SA of 226. With 2 12's I'd lean towards SSA Dcons, possibly Fi X's or the IA 187.
With a single woofer, the options open up some more.

The thing with car audio, is that there is no ONE way to accomplish your goal. There are always more options than you can think of.[/quote']

I probably should have said this earlier but I have a HO alternator. I got it for the harsh winter conditions I subject my car to, so with that come no voltage drop to the amp. It gets constant clean power if that helps settle efficiency.

i would do two ssa dcon 12s ported box. they will get loud, get low, and are built with SQ in mind.

well 700 watts is very low for 2 subs... you will be happy with an sa 15 and spend the extra money on a custom box for it.

no...but you only have 700 watts so your going to want to do a one sub setup

No. How does power dictate how many subs you should have?

Yes.

Having demo'd a bunch of DC subs ( lvl 2 through lvl 4 XLs) and some upper end Fi subs, I think it's between DC, Fi, and SSA based on what I've read.

Fi X, SSA Dcon, or DC level 2s

Any suggestions out of these three? I believe I read that the DCs have the most Xmax, so maybe I higher potential for moving more air?

I've liked the Dcons I've played with. Heck, they impressed me so much I still have two 10's. Very musical, and they get louder than I expected, while sounding better than I expected. For the price range and purpose, I can't think of better.

2 dc levle 2's will be the loudest, dcons the most musical

sonas is a great low power 18 inch sub, will get crazy loud with an 18, more service area then 2 12's

Mach 5 ixl, great for little power.

Mach 5 ixl, great for little power.

this or level 2s..really all are great choices

 

[slim2fattycake 10+ year member]

I'd choose IXL over level 2s.

I'd choose IXL over level 2s.

for more loudness, yes

 

[slim2fattycake 10+ year member]

if your definition of sound quality is handling less power then sure level 2s. IXLs are every bit of sound quality and it doesn't hurt they can take more power.

 

[thatdude69 10+ year member]

I guess the Mach 5 site is down? Because I cant find a spec sheet for the IXLs anywhere..what's the rms rating?

Run the SL units in 2 cubic feet with damping in the box. The BR can

be used in 1.5-1.8 cubes with your choice of box tuning. I suggest

anything from 32Hz to 35Hz. You can use the BR in lower tuned boxes as

well if you are looking into home theater.

the IXL-12 is $169 plus shipping. If you are in the US, factor in

about $50 for courier shipping.

The IXL-10 is $149, the IXL-15 is $199 and the IXL-18 is $229.
