mtx 9500 vs jl w7

If your goal is to get as loud as possible with one frequency, then you could possibly be right.  But if you want it to sound good as well (daily driver), then I think there are many better subs out there.  Also from an SPL standpoint, the W7 does have one advantage.  It doesn't suffer from BL compression like the 9500 does.  

I am surprised to see that the MTX's Sd is so high.  I'm not sure if I personally trust their rating, but I will give them the benifit of the doubt for this discussion.  Having said that, I checked the Vd of both the largest drivers offered by the two companies, and they are both at 2.22 Liters.  So it looks like they both move the same amount of air.

Yes, but rubber stiffens up way before it starts to fall apart.  This greatly effects the drivers performance, and therefore doesn't last as long as rubber.  For a subwoofer, foam is much more superior than rubber.

I agree that they have done a great job marketing their driver.  But it does not mean that some of those patents don't make a difference.  Becides our XBL^2 motor, no other company has a motor as linear as the W7's.  And any sub, including the 9500 would greatly benifit from it. 

But now let's look at it from another perspective.  Which sub is trying to make themselves look good by marketing?  The W7 has done a lot of marketing, but has gotten their reputation as being one of the best by having a solid product.  Now MTX comes along and directly compares it'self to the "king of the hill", and does it with a great deal of marketing talk, twisting of facts, and half truths.  If you want to chastize a company for poor marketing tactics, you picked the wrong one IMO.

I disagree.  The W7 will have less distortion at any output level than any of the subs you mention above.  This is because of it's flat BL curve.  And that is objective fact, not an opinion.

I agree.  That is why I bring facts to the table, which are not subjective.  You can't argue with them, and there isn't another angle.

I guess MTX's tactics have left a bad taste in my mouth.  I'm sure it is a good sub.  But they make some pretty incredible claims, and when looking at the facts their claims just don't hold up.  I know I get a little annoyed at their tactics, so if I come off as harsh in my comments, please don't take them personally.  My annoyance is with MTX, not you.

every one hase very good reason why one product is better than another in varius ways.the botom line is  everybody is judging the prouduct towards what  is going to benefit there inital use for it.I would suggest any body whos trying to decide what they want to spend there money on the jl,mtx ,ex. Should listen to them in your car first before you get missleaded by all the hipe.No matter who likes it and don't its eralvent . If it sound right to you its right.

there is know best every thing lacks something the other dont have.

Hi Steven! Glad you remember that article. For the life of me I couldn't remember where I saw that or what it said exactly, I just remember that the W7 did do some things better than the Brahma and vice versa. It was not my intention to knock Adire or their products, I was just posting what I could recall from that article (which wasn't very much lol!). Thanks for the clarification.

You guys are right that everyone has their own preference.  In fact all you have to do is tell some people that one is better, and they will blindly agree.  But you are talking about subjectivity, not SQ.  Sound Quality is the quality of the sound before it enters our ears.  And that is objective.  It doesn't deal with psychoacoustics, personal bias, hearing loss, and poorly installed equipment.  Some people prefer distortion in their music because they are used to it.  They hear a "clean" sub like the W7 or Brahma, and think it sounds thin, or flat.  And that is fine; to each their own.  But what MTX is doing is trying to objectively prove their sub is better, and when the facts are truely looked upon their conclusions are definitely flawed.  After all, isn't this the point of this thread?

BTW, when looking at the 9500, I still think you can do better for less.  I would much rather have an ID MAX, which uses the same standard overhung motor (so similar distortion products), but with just as much Xmax and and possibly Xmech.  Oh, and it's cheaper. 

I talked to one of our local dealers who sells both our Brahma (flat BL curve as well), and the 9500.  He is a very respected guy on the forums due to his knowledge and experience.  I asked him a while ago what he thought of the 9500.  He said it was loud, but didn't sound very good.  And he said that his customers agree.

Yeah, I was part of that conversation.  It was on the Car Sound forum.  Here's the link to the thread: http://www.carsound.com/cgi-bin/UBB_CGI/ultimatebb.cgi?ubb=get_topic;f=1;t=019193;p=1  Wow, that was a year and a half ago.  Once we get our Arachnid spider on the Brahma, several of the points where the Brahma fell behind (mainly in the suspension) are going to catch up I believe.

BTW, I could tell where you were coming from.  You are correct in that Mr. Clark's conclusions were that the W7 was a better driver.  But I think he was ignoring a couple things, which is why I made my comments above.

Well as was mentioned above, our Brahma is very similar in performance to the W7.  Plus it is lower in price than the MTX subs as well.  And if you are wondering about it's SPL, Scottie Johnson runs Brahma's and holds 4 world records with them.
