2 DVCs vs 4 SVCs

It seems everyone is into dual voice coil speakers these days. I currently have 2 rockford punch 10" p2 10 s4 single voice coil 200 W rms each. I initially intended to sell these and get 2 dual coil versions of this same sub. I have 3 questions

1. would i get a better performance from adding 2 more of the p2 10 s4 RF punch ( having 4 rockford 10" single voice coil 200 W each) compared to having 2 10" rockfords dual voice coil p2 20 d4

2. what are the advantages and disadvantages of 10" subs as compared to 12" subs

3. how do square subs compare to round subs (eg. 12" square sub and 12" round sub)

Please give explanations along with opinions i like to rationalize and logicalize judgements. Thanks

1. The difference would be more bass...4 woofers have more cone surface than 2 woofers...having either single or dual coils makes zero difference besides the flexibility in wiring.

2. Advantage of a 10in sub over a 12in sub...takes up less space normally. Disadvantage...12in woofer has more cone surface area so will be louder (this is with the same model woofers though)

3. How do square subs compare?? Well...a 12in woofer is a 12in woofer...a square 12in woofer will have a little more surface area than a round 12in woofer.

Also a round cone woofer can have higher excursion capabilities than a square woofer...why??? a round cone will have even pressure all over the cone while a square woofer will flex more due to the lack of point symmetry and uneven pressures on the cone...well this last part is what I read from an artical...lost the artical though...but theres a little comparison

What about "octagonal" subs?

well i'm waiting for a class d mono amp to upgrade my system a hifonics 1605d and i fear that it will fry my rockford p2 10 s4 rated 200 W rms so i was thinking of selling them and getting the kicker L5 square woofer but while i was using winisd i noticed there wasn't much (if any) in the response of the speaker performance. So i thought instead i would simply get another pair of rockford to run 4 svc subs. however the wiring would give 1 ohm at 800 W and the amp gives 1600 W rms at 1 ohm but if i set the gain right and control the volume i should keep from frying the subs. plus the output i should get from 4 vented i shouldn't need much volume to get very very loud bass don't you agree?

Nouse...I don't think they call them "explodes" for nothing..lol

However, they don't sound that bad for the average consumer if set up right, at least in my experience. I think thier quality is underated.

And correct about that much power on the P2's..a decent sub yes, but I would lean towards the conservative side with the amount of power you run on those.

Xtant makes some hexagon subs lol

Nice subs azn,

You wouldn't happen to have a "hex" shaped holesaw I could borrow? lol

-------------

Ahh yes yes...still working on the patent for that one lol

maybe like a large cookie cutter you hit with a railroad spike driver or one of those big mallots you use at the carnival to ring the bell?

-------------

yes...I've almost perfected the "cutter's" blade design to cut through 3/4 inch MDF with only 10,000 pounds of pressure per square inch...close.

Can't wait to get the patent for this...I'm gonna be rich ah haha!!!!

You need to develope a device with enormous leverage potential for that kind of pressure. maybe some kind of "break" or massive press? or something you can drive over with your car?

Then we can patent woofers in the shape of famous peoples heads.....The "50 cent" woofer or the "madonna" woofer etc. How about a woofer shaped like a star?  we can claim it is more ridged due to it's "unique" shape and that it puts out the sound at 5 different points, or something to that effect.

we'll be RICH  lol

Hey, ladies... Did you HAPPEN to read the description of the woofer?

Black, custom tooled, die cast aluminum basket transitions the basket to fit into a standard round enclosure cutout

Now go get some sunlight!

Hey, wait... that's me... Maybe I need to get some more sunlight, too! I'll meet you outside!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Awww ...and we were having so much fun with the concept..killjoy.

Ok, meet you outside.  lol

I'll bring the cooler!!!!
