Hasn't been DUMAX verified like the xxx/extremis has. And from what Im hearing, that spec is exagerated. *shrug*

In npdang's Klippel analysis, the Extremis only managed 8mm Xmax IIRC.

Tang Band has a 5.25" driver with a supposed 9.25mm Xmax.

Interested to so how that truly performs.

Oh wow news to me. I know the xxx has been verified at 13mm, I guess I assumed the Extremis had been too. My bad.
Anyone confirm the EU-700 xmax? Know if its been verified?

There's the test, incase you haven't seen it yet.

Nope, I hadn't seen it, now I have. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Thanks. I didn't realize the Extremis had an xmech of 24mm... wow. lol

I heard the new 8" full range speaker from memphis the other day and was very nice indeed. You could try and fit that in the sub spot. I would recommend the mb quart pce's. I used to have a set and the midbass was very good. Good luck!

Thanks for all of your replies they really helped. I haven't heard an answer to this one question though. If I put a sub into the rear deck (so it's sticking out when you open the trunk) will it sound ok because its not in an enclosure? I'm trying to minimize the option of having a sub enclosure in my trunk and I have never heard a free air sub. I don't want the sound quality to ****. Thanks again.

Free-air (Infinite Baffle) is arguably the best 'enclosure type' to go with for a true SQ system. But only if done correctly. The front and rear waves must be completely sealed off from each other.

my extremi offer up more than enough bass for most people to be more than satisfied all around. I want more.... porting eventually. Most likely when I get my elect up to par for a 20.1 on the mags. So it'll be a few months.

But the extremis would be a very good bet for your rears free air, just becareful how many watts you throw at them so they don't bottom out....

What do you mean by the front and rear waves must be completely sealed off from each other? Sorry, I don't much about the technical side of speakers and placement. If you could enlighten me id appreciate it thanks =).

Apparently I can't quote =/

A speaker's cone moves in and out. As it does this, it emits sound waves from the front of the cone (generally what we see/hear) and from the rear of the cone. For xample, its those rear waves that exit the port in a ported enclosure. Now that we've defined the difference between the front and back waves, my original comment becomes more clear. A speaker in an infinite baffle situation must not allow its front and rear waves in come in contact with each other. To do so would lead to wave interfeance problems (cancellation and reinforcement). Complete seperation of the front and rear waves is one of the very characteristics that define an 'infinite baffle' setup. Compromising this means not having a true IB. Hope that clears it up for you. If not, let me know.

dont know but ive heard those boston acoustics comps that are like 1grand a pair amped with 150watts and **** i couldnt believe it. they played late night tip well beyond my expectations and at a volume more than decent considering their size.
