Alpine 15'' or 2 of Alpine 10''

Thank everybody... and speciall JamesRH  

It does mean i dont want to change or stick to my amp i got, at moment i love this amp to dead, i might look for ALPINE MRV 1507 as my cousin, or i bought back my MRV 757, i bought 2 of the same amps (the previous owner used to run it for 2 of 12" subby) and i got it off him like less than half price... it does a great job with my cousin 12" VR ALPINE subby..... anyway... wat i have to do is decide which subby is better between and Phoenix gold 15" and Type R 15"  .....

your explaination is clearly stated the different between 10 and 15" response....

So how do u like the Type R 15"  JamesRH?... wat sort of amp u running off?

Pharaoh, i see where you are coming from, but it is to two different things.  When you are talking about the automobile analogy, the car is dealing with acceleration.  A speaker is dealing with response time, sometimes in the many thousands a second (higher the Hz, more per second).  to go a little bit more detailed about it, we are talking about the mass of the cone, or the density of it.  meaning, the weight of the cone will dictate the speed at which it can respond.  So, comparing the same model woofers (and in some cases, different model) but different sizes, a 15, just by surface area alone, will be heavier than a ten.  thus, it takes the 15 a misicule amount more time to respond.  phew

My single 15" works for me, and it's not that great of a speaker either.

A freind just installed a 2x10 set-up in his car and is not happy with it.

He spent more money than I did, and he can't get it to make the sounds mine does.

Our musical style is varied, anything from classical to Korn and Notorious B.I.G.

Perhaps the real answer is to have both?

Properly crossed over/filtered, I would imagine one could have a 2x10 set-up, and a single 15, and still not be breaking the bank.

Ain't this stuff fun?

hehehe

lol.... JamesRH is right, 15" will get loud and in it way!!...

Nhspike what sort of subby have ya got? ...  kick comp? heard they pretty good... my cousin who had the alpine vr 12" in his bmw, somehow the sub not giving enough bass, so a friend came over and he had JL 15" .. and then we all sat inside his car to listen to the music and his new JL15" .... i really cant tell the model number ... it really loud and pound very strong, but he like my cousin alpine vr12" ...so we took his JL15" out from the box....

mate!!! the magnet is only half of the size of the alpine... hehe and just has a really big cone and can run less power than alpine.. it took only 250 w (i think) coz i saw his little kicker amp on the size, he told me that amp 400w max...  he also has Wega sub too... anyway my cousin just wondering ... which one would you guy think it will give nice deep bass and SQ?,......

thank guys

skyRyder,

It's the Kicker comp, but the cheaper (99 bucks on sale) version, not the comp VR, which is supposed to be much better... dunno about that, as I've not listened to them anywhere that would allow an A/B comparison...

But, with the amount of wattage I'm throwing at it, it prolly won't take the abuse for long anyhow, and I'll get a JL or something to replace it, just for fun.

:O)

Let's talk about Building boxes.... in the Specifications box for 15" subwoofer recommended sealed volume 1.3 to 2.5 ft^3 ........

if i build 2 ft^3 box for the 15" subby .. does it mean it sound tighter than the 1.3ft^3 ?  wat is the different, can anyone explain plz..... i heard my cousin said, the bigger the volume (close to the max of the recommendation) give the better sound?
