Anyone know an online Resonant Engineering dealer?
P.S. What do you all think of their XXX18's?
Thanks

Contact them directly, if you don't have a dealer near you, they will sell to you direct at better prices.

They're OK.

the xxx18 has stupid specs

the adire audio maelstrom has better specs

however i have HEARD neither,but modeled both .

The high Qts on the xxx18 makes it want a HUGE box that is impossible for nice response.

Its not amazingly efficient either.

has anyone noticed how all the new SPL subs have low efficiency. like xxx, w7, and 9500 (mtx).

also the xxx has XBL^2 technolgy, which is similar to orion's new Orion Dual Gap Motor except it was made before orion's version and all... in any case dual gaps with a short coil allow for something of a class AB speaker... the coil is shared by the 2 gaps for part of the excursion. the result is that the BL curve becomes pretty flat and very wide. this reduces IMD and increases Xmax.

No one buys a RE XXX 18 for a nice response. You only buy that one for a HUGE SPL.... nothing more, nothing less.

Indeed, you will get a pretty weird response, but you only need the peak it will have with the "correct" tuning.

P.S. With "correct" I mean the right tuning for your car. DON'T use it for home-cinema or music.
P.S. You might also be interested in the DigitalDesigns 9515??

To be on-topic: I don't know one in the US that sells them online, only in Germany, but as punchpeanut told you: just contact them directly, you WILL get a good price...

Grtz, Joris

small box requirements...
Definately.its crazy.
the adire audio Maelstrom looks agreeable to me.
or a 4ohm version of this-
21" sub

+ then people have to buy 2kw amps instead of 1kw ones

its ok for car audio ,and if ulive in USA u can get such cheap stuff
