I am probably about to purchase a new 12" or pair of 12"s. What can you guys tell me about the si's and their ability to function well in sealed boxes? Thanks in advance!! Btw i've got an ed nine.1 for power and i currently have a single 12" IDMax, looking for more output without losing sq.

They are great in sealed boxes. They are great in ported boxes too. They are just great

Well if any of the reps see this i would like to know some more info on them. Any used subs out there for sale?

the SI D2 is in the category that people call "super subs" or "uber subs". The SI D2 is in the opinion of many and incredibly acurate sounding sub. You would compare it upon subs like the XXX, Brahma, W7, IDMax.

It works wells in small sealed boxes and from what ive heard from others just as well ported. Small power also is no problem as it is a very efficient sub. In those terms its similar to an IDMax, and IDMax's can get movin very well with minimal power.

Now in my personal opnion this is not the sub for the bass finatic. It plays everything well and how it susposed to be, and it can still drop very well, but from what ive experienced its not that sub thats going to play the oberbearingly low notes with lots of power behind it (im refering to the horibly unblanaced rapper cars where you hear bass and hardly any vocals).

Of course this will vary depending on enclosure and i have built a enclosure for it designed specifically to knock out those overbearingly lows (10-25hz). But do keep in mind that even those rap songs with so uber low drops are only briging about 30-35hz. 20-30hz is more what you would get from test tones or ocasionally some techno. and majority of people can even make out the note played on a 20-30 hz (20 and below is the hearing cutoff for humans)

all in all, subs is a great value, a fanastic driver, and has not been toped by any subs i have yet to hear (and ivve heard all the above mentioned subs. Though i do have to be fair and say that i did not make sure al the subs above were in boxes designed to give optimum SQ, since my SI D2 was.

And the new versions might be even better

Well i would like to try one of the new versions but i'd really like a new sub(s) in the next 2-3 months at the latest. The Idmax handles everything i've thrown at it well although it could use a little more airspace. Anyways the main info i need is price, mounting depth, rms power, and rec. sealed enclosure volume. Thanks again, Joey

oh so you aready got an IDMax? The "old" magnum in my opinion was very similar to it. i dont think your going to notice a very big differnce with the switch. if its not good enough for you perhaps you should try putting a little more thought into your enclosure. I personally dont think another 300 bucks on a sub is going to justify the upgrade youll get.

I think the magnum wasa little more accurate, but didnt drop quite as low. i messed with both subs quite a bit. The magnum seemed to be able to deal with mire power a little better too. But all in all i think you should work on your box if its just not doin it for you.

I'm gonna stick with the IDMax for a while. I just bought an ed b6 12" to play with, too.
