My experience with the PROTO SI d2 :)

[ngsm13]

Ok, I had about 4 paragraphs typed up then accidentally x-ed out of all my tabs on firefox...so here it goes again!

Finally...my write-up is here...I've been busy and didn't get time to write anything WHILE the driver was still here.

First, I'd like to thank Mr. Nick Lemons for the opportunity to demo such a unique and amazing driver.

I was watching for UPS everyday when I heard the news the new SI d2 had been shipped out to me. I couldn't wait, when I received the package I immediately took it up to my dorm room and opened it. I stared googly-eyed at the beautiful woofer...picture do NOT do this subwoofer justice. The back-end is SO sexy...nice bumped back-plate...it's hot!

So, I had to hear it. I swapped it out with my rl-i12 in the dorm audio system.
Specs:
-CSS 4.5" xbl^2 Full-range drivers, ported @70hz, powered by 100rms
-Downfiring Subwoofer box, 3 cubes NET @22hz, 250+ rms via Rythmik Audio plate amp

The SI d2 is amazingly musically accurate! I listened to a few Rock Albums including A perfect Circle and Sevendust! Dropped in some rap for the roommates, and the output with only 250 rms was crazy. Windows were shaking, dished rattling, and the balcony floor was vibrating. The SQ and output were great!

Since my truck was out of commission (and has been for near 3 months...with transmission problems...LONG painful story)...I decided to demo the SI d2 in my GF's Jeep Grand Cherokee, swapped it out with her LI 12
System Specs:
-Older Alpine CD Player
-CDT Coax's front and rear
-US Acoustics 4065
-JBL 600.1
-Subwoofer box, 2.3 cubes NET @32hz w/ 45in^2 of port

Again, the output and accuracy was delightful. No matter what type of music I listened to it sounded amazing, no joke. It never missed a note, and the lows were GREAT and it definitely kicked you in the back. With only 600rms the output was surprising! I hopped out of the Jeep at one time and noticed the roof flexing near an inch, with one 12, 600rms, and the sub firing rearward! This driver is amazing, I've fallen in love again! BTW, my g/f loved it for the few days she had it! She even PWNED a few guys with two 12's ( I taught here well )

Those of you who had heard 1st gen Magnums ( I owned two 12's ported with 2400+ rms )...will be MORE than amazed with the new SI d2. It's easily up at the top of the list of TOP quality subwoofers!

So, the driver is currently on the way to it's next destination (Jordan, in California!). I wish I could have kept it for a few days longer, it would have gotten on the meter! (TermLab at the Cincinnati Meet!). But, I politely obliged to getting things on the move...and thanked Nick for letting me demo the driver.

Any questions or comments welcome! Enjoy!

I love that sub... I wanna do it IDPV...

not really...

[CBFryman]

what he didnt mention was what he enjoyed most about the sub was fondling the pole vent....

[UndercoverPunk]

Just because you like putting your pecker in pole vents doesn't mean it's normal...

how would these compare to an ascendant avalanche and what is the rated power although I can imagine they would take 900w rms nicely

I have yet to hear an Avalanche installed

They'll take 900rms NO PROBLEM...amazing subwoofers!

FYI the old magnums where along the lines of XXX's and Brahma MK1's...and avalanches are said to have similar perfomrance to both so id imagine these new Magnums would probbaly be in the same category.
