We got my box finished up at 3 A.M. this morning. I didn't build it myself, but paid an installer who has did work for me before. The box is right at 8ft^3 net (10 gross) and tuned to 33hz with 136^2 inches of port area. All i currently have is a Kenwood amp that puts out 900 watts to push the subs.

THe subs have the copper coil option and I was defintely expecting them to be louder and lower than my previous 15" L7 ran off the same amp. Well, they exceeded my expectations!

My installer rents out a shop from a car dealership. Once we got the box in my Blazer, i immeditately put it on Young Jeezy - Hypnotize to see just how low these suckers could go. AND THEY WENT ALL THE WAY! We had to turn it down less after a few bass lines cause we were afraid it would set the alarms off at the car dealership. Hypnotize literally hypnotized me. I had no idea a setup could get this loud and low off of just 900 watts. I have heard several setups with 1500+ watts, and these babies get lower than almost all of them.

I gave the subs a huge workout today. I didn't expect them to have that great of high end, or really to be able to keep up with the kick drums in rock. I WAS WRONG! At 50hz they are noticeably louder than my L7 and sound A HELL OF A LOT BETTER, especially while listening to rock. The tones come out just so smooth compared to my L7.

I always wanted a setup where "Soul Survivor" would make someone cringe. I now have it! It actually flexes my dash, and sounds great while doing it.I played around with some test tones, and I couldn't believe how loud these dudes were at low frequencies. At 30hz they still had PLENTY of pop. Dropped it to 25 and it was still louder than 75% of the systems around here. I was a bit cautious trying the 20hz tune, so I only put it on about 3/4 of the way. And the result? MY ENTIRE BLAZER WAS FLEXING! Windshield, doors, front plate, trailer hitch, you name, and it was moving! I couldn't believe it still had that much force that low.

The most "impressing" song on my setup is now Late Night Tip. These subs conquer every low note. I love how the bass goes from my entire body, to just my back, to my nuts when the frequency switches up. Just plain awesome.

In conclusion, these subs definitely exceeded my expecations. I just can't believe I am getting the volume and low end that I am with just 900 watts. I was going to put a Rockford 1501bd on these subs to get them to their full potential. But I honestly don't see the need in it. .I really don't want to upgrade my electrical anyway.I wanted something that was LOUD and LOW, and these subs have that with their current power. And they also just sound great on music. Fairly flat response, a perfect SQL driver

WOuld yall fool with giving these subs their rated power?

Can't put up a video cause of this dial-up connection at my summer home.

On another note. My box actually flexes along with everything else.. Does this affect the performance of the subs? If so, what do I need to do?

One more thing.. I pulled a 142.5dB on the TL with the L7 at 50.. I firmly believe this is going to be close to a 145 at about 40hz.

 
Sweeet....sounds awesome...glad it hits all areas, and yeh some bracing on the inside coulda helped the flexing...prolly wont be to bad id guess....be more noticeable when u up the watts though

 
^^^ same here...I have heard nothing but great reviews about these...I wish I could afford the BTL's though but cant afford all the other upgrades needed...Im gunna hopefully order mine by the end of this week!

 
No problem.. You will not be disappointed, thats for sure! I listened to it full volume on my way home from work today on various songs..And now I have quite a headache.. I showed it to two of my friends, and I loved the look on their faces. Both of them immediately grinned and got wide eyes when it started pounding.

I noticed something else on the way home..My CD Player actually moves on the real low notes!

As for box bracing... Could I still add some bracing to the box? Or is it too late? I really don't know if it will hold up on the low notes once I get a better amp.
