JL Audio Subs

[Spiffyfast]

Buckeye...I don't think he'll like that link, its not parts for a 4000 dollar sub kit so can't be of any quality....

This is why I do not argue with you moronic DIY'ers.

Feeling backed into a corner? Just had to give another petty insult in place of substantiative reasoning?

On the DIY market you can not buy the same materials that go into a high end product.

You say this with confidence, yet many companies[Seas, Scan-Speak, etc.] that make the drivers for the hi-end companies sell the drivers to parts distributors[madisound, partsexpress, etc.] that in turn sell the individual drivers to anyone who wants them.

You do not even know if JL will sell there driver separate so how can you say anything about equaling its performance?

It's the W7 technology drivers. They sell the car version, which performs superbly[per 3rd party tests]. You do not need the exact version as they use in the home version. In what way is the car version deficit in performance?

Show me some link to your supply web site were you can buy any part for any product, or show me some links to your wonderful DIY projects that out class the rest of the audio world.

I did state in the thread, that I made anything. I am not the subject in this thread. Your claim[DIY subs must be inferior to retail products] is at subject here. Is it difficult to stay on track? Or is it just difficult to answer a question in regards to your claim[thus the endless excuses]?

Show me were you can buy the drivers that velodyne and krell uses for there subs, because with out the driver you have nothing. I see nothing fancy or outrageous about www.madisound.com can you point me to a certain product.

Pay attention: I will not direct you to any specific products. I am not here to teach you about subwoofer design and/or the relevant perceptual issues and room acoustics issues. If you are curious about this subject, please do the footwork for yourself. The subject here: you claim that DIY subs can not be equal quality to retail products. Well, I asked you to give valid technical reasons. You have not given a single one as of this point in time. If you can not give any reasons, then stop trying to change the subject -- I will not fall for your attempts to distract the issue.

If you can buy the same matterials used to produce a certain product then yes you can, but were are these matterials?

You are changing the subject[redundantly to cloning], once again. This is not the issue in this discussion. Refer to my last post.

Yes it is because you are compairing your DIY product to the JL and if you can not buy the exact driver then it can not match it!

Why velodyne or krell....I just showed where you can buy the exact subs SVS uses and the amps.....I'm not seing your point here either, even if you can't find the exact components certain rediculously priced manufacturers uses there is no reason why something can't be built to be comperable, it's like you saying that its impossible for you to build a car engine thats as good as a mustang gt's...and us saying hmm.....well other ppl make parts close to that and I can put em all together myself

Here's your JL home subwoofer in a 13" that's impossible to purchase:

I wouldn't hesitate to put either of these in a home sub, either.

I'm not seing your point here either, even if you can't find the exact components certain rediculously priced manufacturers uses there is no reason why something can't be built to be comperable

Take a look at the high end SVS and HSU stuff then we can talk about price. Those companies are a little more then kit selling becasue they design there entire line and then give the buyer the option of customization or buying everything seperate.

 

[Spiffyfast]

Kit Selling I dont know what forum u've been reading but SVS and HSU are always at the top of lists when it comes to high quality subs.... anyways those are replacement parts, I'm sure any manufacturer if you called them and worked something out would allow you to purchase components but that doesnt even matter, your just b.s.ing some other point to not acknowledge the point of this argument

Some of that is nice but the bass drivers do not impress me becasue once you see the driver out of a velodyne everything else looks so historic.

I added a few to post #70. These are the specs on the Cadence 15". I bet two of those with an appropriate class D amp would give that JBL a run for the money.


Voice coil: (3) Four Layer
DuPont Kapton voice coil material
1 ohm = 1/2 Ohm or 2 Ohm
Dual 2 ohm = 1 Ohm or 4 Ohm
QUAD 1 ohm = 2 x 2 Ohm or 1 x 4 Ohm
1500 Watts RMS
5000 Watts SPL "Burp Power"
200 oz. magnet
90dB spl at 1w/1m

The home version has been modified from the car version.

Come on the velodyne DD has a magnet of 380 ounces, and it keeps 100% of the quality.

Now find a 3800watt RMS amp to power them.

 

[WmAx]

Can't even remember the first part of this discussion? I*V=P, P*0.9 for the efficiency factor of a best-case scenario using a digital switching(D) amplifier.

So how do you get 3800 watts RMS to a speaker from a 20 amp(I), 120V(V) circuit?

BTW, the power ratings on said subwoofers(like the JL ones) are not continous, nor could the speakers even begin to handle such power for more than a millisecond without burning out the voice coils.

This one would be killer, HAHA I WIN!!!!!

Or this one

Or they might be using two amps like these bridged 1500 watts each....

Ask JL because that is what the gotham is rated at.

 

[WmAx]

So, they can defy physics? Or is that an instaneous(misleading and useless in otherwords) power rating?
