Well, I was getting ready to order my Lotus Refs, when I was talking to someone "in the know" about them and was suggested the Extremis was actually a better driver. Can anyone comment on this. I have used the Kodas before which were very capable for what they were, but no experience with the Extremis.

"Better" ... depends on how you look at it. They're certainly nice drivers, but I wouldn't flat out say that they're better in every aspect.

I would purchase one myself and give you all a review, but the mounting depth renders it all but unusable for most of us. Of course if someone wants to send me one, I'll be happy to give it a spin :)

Guess I'll have to order up a set to send your way then. Would be nice to know how they'll stack against the Lotus, Revs, and Excels. According to Dan, that was the design purpose; to rival them in all aspects while providing a lower price tag. Adire has yet to disappoint me, but I know Revs and they've been my favorite so far as long as the application has been correct.

Hello ,
Today i made a brief non scientific comparison between the Extremis and
koda6 in car.
I placed the Extremis in one door and koda in the other and this is what i found,
The Extremis wont go into a koda baffle hole :D ,it needed a 12mm spacer ring on top of the existing baffle , I riged up an old soundstream ref 300 , and set the P1r 50 hz high and full range there on up ,stuck in whatever came to hand ,(Kate Bush ever for ever) , the extremis midrange was noticeably clearer and more detailed , but the thunderous midbass i was expecting did'nt really materialise ,and in general the kodas had punchier lower bass , i realise there was a power difference but i did try to compensate by adjusting the volume .
I then set about taping up the box the Extremis came in to simulate a sealed enclosure , box is aprox 10 liters , installed the extremis and placed in the kicks , to my ears this made a huge difference , midbass
punchier ,clearer , after listing to a few tracks on Sinatra's hits ( dont llaugh ,great midbass on some tracks) , fading back to the koda it seemed to be lacking in most areas ,especially the upper midrange where the Extremis excells. btw the power i was giving them (aprox 50w) seemed adaquate judging by the way the cone moved , and was loud as id ever need ,
Tried something similar last week with CSS125 , I compared it to a Hertz HM1000, a fairly regular car speaker , both were placed in cardboard boxes
:roll: and positioned in the kicks , the CSS destroyed the Hertz on just about every level but the CSS midbass was astounding for one so small , real bass just like as if my kodas were running .
I would send them to np for proper testing .... but im in Europe :D

I installed my extremis's a couple days ago. I have absolutely no complaints. They play low with ease and don't break up much in upper frequencies. Right now they are getting about 50 watts apeice. I will try them with 100 later this week, to see what kind of differnce the extra power makes.

Wha's the application, crossover points/slope?

Well, right now since my car sucks, I have them in the doors (fully sealed) Eventually I would like to try them as either sealed in kicks, or as a midbass only 3 way setup.

I am using an Eclipse 8053 for the crossover. Right now I am liking them at 6 db slopes at 80 hz and 2 khz. I have a cal25 tweeter on a 24 db slope at 2.5khz. I will also try a set of LPG's that I just picked up to see which one I like better. These are easily the best mids I have heard in a car.
