Well i put 15 and subwoofer to be descriptive but its the legendary tempest and only comes in one size.
I ordered this sub for a friend and a profile CL600 and bridged it to 2 ohms (not recommended by profile but i did it anyway)
My first impressions when I saw the sub i was like man... this thing is small but it wasnt for me and it looked like a good deal for $125 so i was gonna go with everybodys opinion on this.
We spent about 6 hours building the box and trying to get the massive thing in the car (took out the back seats) and after we put up all the tools we were set.
I wasnt expecting much from it because i have a 12" xxx but he played some music he had in ahead of time and it was pretty **** loud. I went inside and made a cd and we went right down the road to eq the system. I set the gains right and turned the bass all the way down on the hu so it wouldnt distort his stock speakers and started playing some music. I put in nothins free by lil jon and the eastside boys and i was amazed at how loud this thing got. the lows were also amazing. Next i played thug walkin by yin yang twins and this thing put out some earth shaking low bass. I continued to play some more songs and I was more and more impressed with it.
Heres the setup
some low line kenwood hu
stock door speakers
Adire Tempest in a 4.5 cu ft box tuned to 24 hz
no sound deadening
Bang for the buck factor really plays in here. the sub is on sale at www.visionaryaudio.com for 125 shipped until december 26th. I got the amp for 102.99 on thezeb doing a price match off of ikesound.
built the box for about 30 bucks
so all in all it costed 260 and he has an awesome setup.
if you are a fan of LOW bass and have lots of space, i say do 2 of em
This sub is one of the best ways to spend $125
