system recomendations

If you want a sub that uses a tiny enclosure, then the Brahma 10 is a great choice.  JL makes several different subs in several price ranges.  Which one were you looking at?

For the front and rear speakers use an amp that has a rms rating of 50w x 4 @ 12 volts. Any more than this is going to be gravy. If you want more that's fine but most systems thrive with this much power. I swear that Stephen can literally smell the forums and when the word Adire or Bramha is mentioned he's all over it. I too am considering the line for next year. (Stephen - send me some CDN dealer info dude). If space is a concern for you consider also the MB Quart Ref series of subs. I was highly surprised by the output of a single dvc 10" in a 1.25 cu.ft. slot loaded enclosure. Played deep, sounded good and played to a great volume level. It would need a mono 2 ohm sub amp that has between 300 - 500w rms. Concept has a couple of great amplifiers in this realm, the CA604 and the CA525M. www.mbquart.com www.conceptconcept.com

Well I'm not too familiar with the W6v2.  I know that the old W6's parameters matched up perfectly with our Shiva, so they would perform the same.  But the v2 from what I understand has gone through some changes.

As for the Brahma and W7, they are very close.  Both use different motor technologies that both lower distortion, which put them at the very top in SQ IMO and many others.  Both also have very similar displacement capabilities, so output should be very similar.  The differences are that the Brahma is designed for a smaller enclosure, but is a little more inefficient.  The W7 has a great deal more suspension travel, meaning it will be harder to break.  The motor design in the W7 is somewhat flux inefficient which is why it has a higher Qts. for such a large motor.  This effects it's frequency response a little.  And finally, the inductance is a little higher on the W7 which will effect it's high frequency extention and transient response a little bit.

So what can we see from the above?  Well if you need a small box driver, then the Brahma might be a better choice.  But if you have a bit more room to spare, but don't have as much power, or like to abuse the driver a little bit without fear of breaking something, then the W7 might be a better choice.  But other than that, I truely think that they are the best performing subs on the market.

That depends.  The 12 offers you 40% more cone area for a very small price jump, so I usually recomend going for it.  The 10 is best for people who want a lot of bass, great SQ, but need a very small enclosure (.5 cubic feet and down).  So if you can stand a 1 cubic foot enclosure, then go for the 12, but if you want the enclosure smaller then that, then the 10 would be a better choice.

The power you need will be determined by the enclosure used.  I ran for a long tome only 500 watts to my B10 and it got impressively loud.  In fact when I jumped up to 1200 watts, the output didn't jump up as high as I was expecting.  You can get very good results with that amp.  Around how loud do you want to get, 120dB, 130dB, 140dB plus?  To get a Brahma 10 to full excursion in a .5 cubic foot enclosure, you would need over a kilowatt.  But you don't need to get the driver to full excursion.  After all, then you are just taking the risk of breaking it.

Hehe.  I still want you to come down sometime and take a listen for yourself.  We have some pretty cool stuff to look at, including a very impressive home theater setup.  Just bring your favorite CD's.

As for the dealer part, I suggest waiting till the beginning of next year.  We are doing some major changes and won't have everything ready till then.  But I can have our sales guy contact you with more info if you would like.

hey steven, does Adire has a dealer in Albuquerque, NM???

as far as how loud i want to go i have no clue. i'm not wanting like competition sound, even though some say that the system i am putting together could almost be there. i just want something that hits when i want it to. every once and a while i like to turn it up and just thump. i built a 1.25 cubic foot box and it's alright in my trunk, but it's a little big for my liking. one reason i was attracted to the brahma was because of the box specs, they seem super small. by no means do i always want to be pushing the driver to the limit because i know how much harm it can put on the driver and it just stresses it. i want something that will have a little bump with the bass but doesn't over power the highs and stuff so people inside the car can't hear anything but bass, like i said though, every now and then i get the itch to crank it and thump down the street.

It doesn't look like it.  But here's a link to our dealers page: http://www.adireaudio.com/TextPages/DealerListFrameText.htm

Then as far as our products go, a B10 in a .5 cubic foot sealed enclosure and about 600 watts should do you just fine.  It will take you into the mid 130's fairly easily, and will have a tiny footprint.  Good luck with your decision.
