At Low Volumes They Will Sound Close. At Very Low Volumes But Bc There Is More Surface Area Moving The Bigger Sub Will Be Louder.

 

I don't need your "education". You're incorrect. And even if you COULD get a 15" to sound like an 8", you won't likely in a Z.

I do have a lot to learn. But not about this. Noone has made me look like an idiot. You're just against me because I think it's a dumb idea to get a 15 and I voiced an opinion rather than just saying, "yes it can be done."

Yes, it can be done. But it's probably going to sound bad and won't blend with the music. And you will fatigue from the constant rumble a large transducer like those in a 15" will produce.

Me personally, I like blueberry yogurt. It's probably my favorite yogurt. Though you may disagree. Usually I put oatmeal in it. I find that blueberry yogurt blends much better with oatmeal than other yogurts. Yeah it's all yogurt but to me, blueberry blends the best. I'm sure I could add enough acids and sugars to plain yogurt to make it taste similar but it really won't compare to blueberry.

I also like that tapioca pudding. Though the analogy is irrelevent.

 

Why will you fatigue from the air moved by a 15?

Why will it sound bad?

Why does a 15 rumble and an 8 doesn't?

Why won't it blend?


explicame por favor

Pretty please

....awaiting your response.

 

Knowing full well who JimRHIT works for and what he does for a living I think I'm going to grab some popcorn and watch you get pwn3d muppet. You're going to lose this one badly. Bow out gracefully now for your own good.

 

Dude, if you think my 13w7 sounds poor or is rumbly etc. etc., come out to California and I'll show you the definition of amazing audio fidelity.

You need a reality check with car audio, because you really don't know what you're talking about. I feel that the above few posts do a good job of educating you on these topics.

Please read them because the underlying information is all correct. If you don't take my word, take Jim's.

This is not an opinion; this is a FACT.

Ravi

 

Thanks Bro

 

I've heard 13W7s. I don't like 'em. If you do have fun and enjoy. There's a reason they sell subs in different sizes and it's not because one looks better. It's because they respond differently.

Oh I am sooooo po3nedzzzzzzzzzzzzzzzz!!!!!!! OMG LOL ROTFLMAO ***

 

How do they respond differently?

Please explain how this works...

 

Don't patronize me. I'm talking about personal preference here and you're trying to argue the physics of it. Which you're not entirely accurate on anyway. And I dont really care who you work for, I've been building sub enclosures for 10+ years and I know in a Z it'll sound like ****.

Why? Because the Z is a little car with not a lot of air space to begin with. You throw a big *** sub in there with with a cutoff around 20Hz you're going to boom like a **** every time you start producing tones that low. Yeah... a 15" can do it. And it can do it at a higher efficiency, but it will sound like **** in a mall vehicle like the Z.

A smaller sub, on the other hand, like a 8 or 10, will not have such an efficiency, which actually is to it's advantage in a small vehicle because then you won't get that boomy sound when you go sub 30-35 Hz range...

Granted, you can make up for some of this through gains etc, but TO ME (and this is the main point here... 'cause it's an opinion....) to ME... it's still going to sound bad.

Does JL make a 15"? I think so in a w3v2 or something. Dunno, check the numbers yourself. There's also plenty of programs out there that you can graph efficiencies and SPL etc on in given volumes. I don't have the one I used to use anymore now that I've switched to mac.

And Ravi, I like your car, it's a sweet install. If I was in your area I would come check it out. But I'm not. Though I've heard enough 13w7s to know I don't like them. That's why I went with 8W7s. But if you do, and your install has compensated for all that... or atleast to your liking... good for you.

Jim if you want to talk more look for me on AIM or something.

 

I don't really feel like doing this. Simply put, you are wrong. I understand you have built boxes .... I started this hobby out that way .. for me, some dumb luck and 2 engineering degrees later ... I ended up doing better things.

I am not trying to disrepect you here, you probably can make a hell of a box ... but you really have a lot to learn about this stuff (I did too, and still do ... but there is a lot that a common (or even expert) installer doesn't know).

Simply put (and put again) ... ANY well designed transducer will respond exactly the same as one twice its size. At higher output levels (of bass frequencies), the larger will sound better in that it moves less to create the same output.

You have a preference ... good. Your preference is based on experiences with products crammed into boxes that don't suit them or the subwoofer is not designed to be accurate. Grab yourself and Adire Maelstrom ... an REXXX18 or an Ava18 from Ascendant ... install one properly and tell me it doesnt sound good.

An old friend once demo'd his car with some Aura1808s in a IB trunk in a Olds Cutty ... everyone that heard it SWORE they were are pair of 10s or something since they were so amazingly "fast" and accurate (the owner was a huge SQ guru) .... then he turned it up ... hair tricks .... and bent trunk lids followed....but that car always sounded amazing. Properly installed (and good drivers) can sound good in any size, with any moving mass ....


For once in a guys life here .. SIZE DOESN'T MATTER !! ...


Will anyone be IB'ing a 350Z ... hell no ... but can you find a nice 15"er that couldbe set up for SQ, yes you sure can. An 8" deep false floor will suit once phenomenally well.
Is it a simple install? No.
Is fiberglassing involved? Yes
Can you sell this guy a box? No.



OP,

Please do the 15 ... if you need help ... ask us ... a lot of us here have some good experience making custom boxes for these car ... we can get you some good ideas.

Jim

 

Jim, I know what you're saying but I don't think it addresses my point. YES, as I said, a 15" is going to produce lower tones and at a higher efficiency. But as you said, you've got to up the output to do that. Whereas with a smaller sub, you won't get the same tonal range, but you will, in my opinion, get better blending through lower efficiency.

Actually I've heard some of adire's line. I think it was a Koda though. 12" if I remember right. And it was not as accurate as I would have hoped... though it was in some guy's DIY box in an s2000.

You keep saying that people think it sounded like a 10" or that 15"s can be tuned to produce the same response as a smaller sub... which also goes along with what I'm saying... If you're trying to make a 15 sound like a 10... just get a 10.

 

And whats wrong with 20 inch chrome wheels?

 

I always thought more, smaller speakers sounded more clear than one massive big speaker.

 

Thanks for the nice comments. I do like it and thats what matters. I understand SQ is a subjective thing...but everyone that has heard it loves it =)

You'll love your 8's!

ravi

 

Historically they have/do ... but that is really for no other reason than lack of control for the cone (cheap motors). If you are willing to pay the cost to support the higher moving mass ... you will get a similar speaker.

 

Muppet, you are dead wrong.

Obviously you haven't heard a properly installed, good quality 15" subwoofer. While 10 years ago....hell, even probably 5 years ago you would be right (but not for the reasons you have posted). I highly suggest finding someone in your area with a proper setup with some ID or eD 15" subs and taking a listen.

Back when 15's were overwhelmingly sloppy it was due to the design (mainly the crap motors).

 

No way an 8" can sound like a 15" or V/V.

Dude, 8" should only be used for mids IMHO. Rap music is the only reason that car audio is an industry. Nobody cares how R.E.O speed wagon sounds through an 8" mid woofer!

 

Wrong and wrong.

Any transducer can sound like a transducer, regardless of size , given that it is operating pistonically w/o distortion.

The car audio market exists in the aftermarket to support all genres of music. High-output bandpass boxes and extreme excursion subs are the by-product of a bassline-driven (ie hip hop, rap, pop, techo, etc) music tastes of today's public. You assesment is shortsighted and stupid .... there are people out there older than 15 that like loud music ... rock, country and classical can all sound great at extreme levels as well.

An example for home audio ... some of the highest output speakers in the industry are made by audiophile companies ... I would bet you that 90%+ of them will never see a hip-hop or techno bass note in their lives.

Get a clue ... or please ... just stop trying to be intelligent.

 

if you like spl competition just throw a dub7 in the trunk.One should suffice

 

Please stop spewing your ignorance into other people's minds. Yeah, rap, the ONLY good music. Hahahaha
