Cone area vs power.

[Dan208]

Something that I was thinking about earlier today. Say you've got the choice of running either two lower end subs vs one higher end sub (from different companies). All subs in question are the same size and run on the same amp. The two subs would be getting 300 watts each, the single sub would be getting 600 watts. Enclosure size would be optimal for each sub.

In this situation does cone area beat out power?

id think so yes.since more cone area would be more louder assuming that the box are optimal for both subs either dual and the single ones.

If the 2 subs are seeing 600 watts for the pair, they will be louder than the single sub with 600 watts.

I figured as much but wanted to get some feedback.

i explained this in another topic but basically it is physics.

loud=pressure=air movement

since two cones have more potential to move more air they are normally louder

but say this one sub can move twice as far as the two subs. in theory (if the cone area of each sub individually is the same) the they should be the same volume of air displaced.

generally speaking though the 2 subs off 600 will move (ex) 10mm whereas the one sub off 600 will do 15-16mm

so the two subs can move the cone area times the vertical displacement of air same for the single sub

random numbers for visualization

cone area of single sub is 6

so for the 2 subs the equation is 6*2*10=120

single sub 6*16=96

see how it moves a lot less air. there is the reason why it is quieter more often than not

*note* these arent the real formulas just a basic idea of how things work.

My single NightShade 15" was 1.2db louder than my two cvr 15"s off the same power.

My single NightShade 15" was 1.2db louder than my two cvr 15"s off the same power.

that happens a lot. my single 3512 is louder than my cvr 15's off same power

but that was mostly failure of box design on my part.

but when you look at those subs vs the cvr's there is a shit ton more potential of moving air correct?

im not saying it doesnt happen because it does.

but the normal cheaper way to do it is more low power subs

like for example i boght the cvr's because i didnt have money so i spent 280 on those. pretty loud

then i went and spent 4 somethin on this one sub and its just a bit louder.

a lot of variables to consider

with more cone could also mean more motor force as less power compression as you are spreading the power across more coils

Just for the record, it's 2 10" Clarions vs a single 10" DC Level 3.

ive been thinking of somethin on the lines of this.

its my take on wats better for and spl setup over a groundpounder. tell me if it sounds right

for spl you just play one tone at the box tuning so there is very little excursion

for a groundpounder you want to move tons of air

so spl would be more geared toward having tons of cone area

and a groundpunder would be ok with less area but more xmax per sub (but the same could be done by adding cone area).

^^does that sound about right?

kind of on the same topic
