Ed's New Sub Vid

[cobra65427289 10+ year member]

Telegon, I believe you are way out of you league on this one. Warbleed knows more about speaker design than he leads you to believe. Some of the stuff he has said in the past has made my head spin.

As for dimpling Telegon, Why don't you talk to the many satisfied IDMax users.

Any high excursion sub that uses a tall roll surround instead of a wide roll surround will have that dimpling. Such as the Massive CW, IDMAX (which in my opinion is a much better driver the the W7), Any TC sounds sub from the TC3000 and up, the TC 3hps did as well, I am sure there are many more too. All of the ones I mentioned are very capable subs. There are many benefits to a tall roll surround (the dimples are a side effect that really cause no ill affects). For example (and someone more learned than I correct me if I am wrong on this). A sub with a Tall Roll surround compared to a sub with a wide roll surround of the same size w/the same amound of linear excursion will displace more air due to the fact it has more SD with the same amount of XMAX.....Telegon I think you are a tool and you have no clue what the hell you are talking about and you should quit now while you can still save some face.

ill still wait for him to disprove my post on the previous page. it is ALL valid info, and it applies to speaker design.

All he's said is that i should quit because he feels he knows more than me, and youre all just sackriding him.

bunch of *******

I'm new to caraudio.com...and this is the first thread that I have read(rhymed) ... I now know that I will like this forum, because there are some people that have strong opinions...however I will say this, (and these ARE FACTS) As a company ED has had success because of two things: Advertising (including word of mouth) and selling on price. In the car audio buisiness you do get what you pay for, and the fact is that their subs are good for the price, but to put it bluntly...i think they sound like shit. There are many many other speakers you could buy for just a little more money that would sound awesome...NOT including anything by JL. Peace.

T-bag, good to see you on the forum. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And Kurt, I see you came out of the shadows for the surround discussion. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Too bad I saw this thread a little late, I would have enjoyed getting in on that.

God ****it!

I just read all that bullshit on surround and FEA arguments blah blah blah and find out the thread was bumped for the cheapo sub eD has!

I want my 20 minutes back!

You conveniently forgot the biggest reason of all, that i stated on my last post... which is the Price Factor.
Let's rewind behind the issue of whether they are intentional or not. The dimple is there because surround material cannot comform to the travel to which is subjected to.

Why? Because the thickness and profile (shape) of the surround are not conductive to the type of movement it is subjected to.

What is a dimple? A dimple is 1 more movement that the surround is subjected to, therefore, 1 more thing that can go wrong. Whether the dimples are planned or not, the fact that they are there means that the way they act will have an effect on the movement of the cone.

If 1 dimple changes shape or dimension then the whole balance of the cone is thrown off.. and there goes your SQ and over time, there goes your speaker. There are speakers with a 4" peak to peak excursion which exhibit no dimples under full excursion, for example a 13w7.

No FEA was done on the eD sub. I dont need to do more than just look at the video to deduct that. No engineer on his right mind would let that surround hit the market after putting it through cosmos.

Since you are so much of a weak minded peon that I have to go over this point by point, so be it:

Some effect yes, an audible one? Nope. I already covered this before, apparently it escaped your comprehension.

Ah yes, I covered this before too, oh dimwitted one. The 13w7 uses a wide roll surround. Because of the nature of the half roll surround, it won't exhibit any dimpling near its limits. Thats due to its shape.

In the case of high profile surrounds such as the ED, it will dimple because of the shape of the surround, due to the surround being more tall than it is wide. This has NO ill effects when it is accounted for in the FEA design of the surround, which in ANY surround designed for this level of excursion, it is going to be.

This one was already addressed as well, but we already know your feeble little mind came up with this laughable little idea. You should go tell this to Image Dynamics and TC Sounds. Both use LOT of FEA design, and both use high profile, narrow surrounds which dimple. They perform very well. Digital Designs has used high profile surrounds for years with no ill effects as well.

Hmm...I wonder why that is. You aren't even worthy of my time fool. Everyone here is laughing at you, you just haven't figured it out yet.

My experience with subwoofer testing points otherwise. Hanging out on the internets doesnt mean you know more.

Yes, it does have ill effects, testing and r&d on speakers proves that dimpling of the surround does create ill effects, whether they are 1 month or 1 year after manufacture is the issue, but FACT OF LIFE, is that it DOES ****ing matter.

Good for them.

Funny how you have to resort to insults to get your point across.... and in the end your argument is still disputable.
Go back to SeaWorld with that shit. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Okay, now I call BS. Lets see some, ANY proof at all, that your ears can discern when a speaker's surround starts dimpling.
You can't, we all know it. You are digging your hole deeper now.
