Simple sub size question.

[ThxOne Premium Member]

The choice:

4 - 10" subs wired to 1ohm sharing 3,000w

OR

2 - 15" subs wired to 1ohm sharing 3,000w

Why would you choose one over the other?

Would depend on vehicle for me.

In my mind. I’m thinking lot of things.
how much space do i have in the vehicle? What is the frequency response? Things along those lines.
Let’s say all things being optimized. I’m thinking the 4-10s would be better for daily driver. More cone area then 2-15s. While the 2-15s might be able to play lower in bass frequencies. Are the average guys going to be able to hear a 20 or below sound?

Probably 15s. Mainly because I think it would a simpler enclosure.

SUV all day.

I almost pulled the trigger on a 2002 Grand Cherokee. But I did make up my mind. It will be a Grand Cherokee. I am running two 10's now that are going to be upgraded in the Elantra but in the GC I want to frighten people.

I'd do the 15's (if we're talking same subs but different sizes)

Most likely cost less
More cone area
effortless sound
easier box

What 15's are you looking at?

Maybe CT Sounds but haven't decided.

I saw a disagreement so I googled it myself

2 15" have more cone area.

I remember my two JBL 12's hit 145db on 1,000w. I think two 15's on 3K will get down!!

In my experience, larger subs play lower, so I'd go 15's.

However, EVERY teenager has TWO subs, so I like four 10's for the wow-factor.

Ultimately, I prioritize a pretty install with whichever route you choose

I triple sub set-ups. 1.3 or 2.6 ohms so lots of amp choices.

I have the amp. The Smart3

I got 2 of the Dayton RSS390HE-22 sitting in the boxes I need to move but shipping would be crazy most likely they weigh 35 pounds each..

They would destroy on 3k but final ohm load on the pair would be either .5 or 2 which makes things a little trickier.

Yeah, I looked at those, I think the Smart3 would melt them sadly. Smart3 does 3K at 1-2ohms.

They take 3k to reach Xmax in the proper box..

Thermal limits would then be a concern..

I appreciate the offer but I am going for brand new virgin coils.

My original thinking was flawed.
I looked it up. To find the area of the cone looks like it is radius x radius x 3.14
An eight Inch sub 4x4x3.14= 50.24 for single sub.
A single 15” sub 7.5 x 7.5 x 3.14 = 176.625
Least this is the information I found.
