Hey guys, i need some good advise, i just reading all the stuff and i wondering that,  the different between an ALPINE subwoofer and 2 of the ALPINE 10"  which would give deeper bass and faster response?... people said that 15" is ait slower response than the smaller size however it louder and deeper bass?

what do you think? anyone has any experiences in these type of situation?.. coz i am thinking of buying subwoofer this week...

When people say a bigger sub has slower responce or plays different bass notes, that are talking out of their ass...All subs create the same sounds and peform the same way, its your amp that may not be able to control the responce if its not powerful enought, the only difference you get from different sizes is the amount of SPL produced and thats purely due to cone area...I say go big or go home, and would get the 15, but 10's will probably be a better choice if your going for everyday driving

well, maybe i can talk out of my ass for a minute.  A 15 DOES provide a slower response then a 10 .  The larger the mass of the cone (or dome diaphragm), the slower the response time.  This makes perfect sense b/c the heavier anything is, the more work is required to move it.  don't believe me, check out the MECP manuals, and read it for youself.  all subs DO NOT create the same sounds.  How is a 6" sub going to hit the same frequency response as an 18" sub.  the amp sure has a lot to do with it, but it is the speaker playing the sound, not the amp.  The amp is producing an analog signal for out ears to interpret as music.  skyRyder, choose the size of your woofer according to the music that you listen do.  A heavy metal fan?  go with the 10's they more accurately reproduce the bass drum.  a hip-hop fan.  Go with the 15 b/c of the deeper bass response, thus a deeper tone.

Put the 15 in a sealed box... like my 2 Soundstream 15s are, and they can be tighter than hell. Most people can't believe I have 15s when they hear it.

I would have to agree with wizzle(and i like talking out my ass) the fact is not all sub sizes play the same notes, and therefore should be chosen according to your music and ear preference. Hence if you want good tight bass i'd go with 10's (this is a general rule of thumb though) deep droney bass go the 15 or good all round sub would have to be the 12's. You generally will need more power to effectively run a 15 than you would a 10.

Please note: You can with correct box design get a 15 to play nice tight notes but it will not come anywhere near a 10!

I have to agree. Not all subs will hit the same frequencies, let alone react at the same time. Look at the different frequency responses for any 10, 12, and 15 on the market. I have yet to find 2 different size subs with the same specs (now, I am talking about "Quality" maufacturers, not junk that throws specs out there for the hell of it because it looks good)

10's are great for quick tight bass. 12's are a good "all-around" sub. 15's are great for a low bass engine.

when looking at the Alpine type R's there is a playable difference of six hertz....very neglagable...and subs are built to handel their own mass...hence 10s and 15 dont have things like same magnet, voice coil or spider...they come back to rest at very close time ratio...only underpowering them can cause that to be a problem as the amps job is not only to move, but to stop moving the sub. what i was trying to put through that if SkyRyder already has an amp and does not want to change it...make sure it can handle to power needs. Ive had Type R 10's and 15's..i listen to alot of drum and bass and the 10's played ever note extemely well.

That sounds a little better then your first post...

You would need an amp that can reliably push at least 500 x 2 or 1000 x 1 at the correct impodence to properly push (2) 15" Type R's.

You would need an amp that can reliably push at least 300 x 2 or 600 x 1 at the correct impodence to properly push (2) 10" Type R's.

And I agree, always make sure your existing amp can handle the subs that you plan to add or change. Otherwise, you should consider choosing different subs or a different amp as well.

Saying he 10 will move faster doesn't seem right to me. The 15 can move just as fast. It has more mass, but that just means it will take more power and a larger magnet to get it to move as fast.

Take cars for example. Larger cars can out accelerate smaller cars... they just need a lot more power to do it.

But, as a general rule, 10s seem to be punchier.

Thank everybody... and speciall JamesRH posted_image 

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

how do i like the 15's.....I loved the sound of the 10's i had...the 15's....they are Freakin loud....thats about all i can say...they are built for SPL...they dont have much range, but then i am running them in tuned ported SPL spec boxes...so never really heard them sealed up....im running them with Phoenix Gold Titanium series amps ( ZX ti Series)

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 posted_image

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)

DO NOT mix 2 10s and a 15. Ive seen people try and it NEVER sounds right.

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?

normally a smaller box will be tighter, but at the expense of low bass responce (like below 45-40 hz).  smaller boxes also tend to be a little boomy because of that.  a bigger box can give a little more spl down low, but the overall clarity might be compromised.  my two cents on the 15 or the 10's, i have never heard a 15 that sounds like to tens in terms of quickness, and i have never heard 2 10's sound like a 15 or 2 in terms of SPL!!  15" for SPL, 10's for clean SQ

The most efficient sub is a 12" and getting 2 12's would be much better than a 15 or even 2 10's if a proper amp is used. although price difference will be a bit higher it is well worth the sound difference. Again mixing brands of subs or size is something nobody should do, the difference in response times mess up the sounds.
