Awesome sub

Very loud for a single 8" subwoofer. I highly recommend this to anyone.

I love these subs!

Just as the title says, I love these subs. They sound good, produce the low notes accurately, and hit hard when you want them to. You read reviews where people say "my friend thought I had 10's" It's true. I have used the solobarics since they first came out and everyone always thinks I have larger subs than I do. I currently have two of these 8's in my wife's minivan stuffed in the spare seat storage in the back. They are being run with a Kicker CX600.1 and I am the only one in the family who can stand the music loud enough to make the subs work at all. The website says it needs 0.5 cubic feet of space but I called Stillwater Designs and they said it was a misprint. They only require .33 cubic feet as they always did for their 8" solobaric. My box is .39 each and hits all the way down to 30 Hz before the subsonic filter cuts off the signal. I have another L7 8" in my car run by a Kicker IX500.1 but only needed one as I left the rest of that stero stock and it already overpowers the music.

Great Sounding Sub!

I've owned this sub for about 6 months and it really hits hard for a 8" subwoofer. I have it in my regular cab truck and I'm getting ready to put one in my supercrew.

Great value and great product!

I was hesitant on buying a set of 8" subwoofers since before this I ran a pair of 15" RE Audio. But since these subs were the perfect size to go under my seat and I could have a back seat again I really am happy with them. I have had no issues with power handling what so ever. I have a US Amps 2000X running them and the subs sound great for just being so small. I would recommend these subs to anyone with space issues. These are defiantly ones that pack a punch.

Great subs!

I have a 2005 chevy silverado crew cab. I have very little room to put subs under my seat but I found a box with 8" squares cutout so I had to choose between 8" 2 solo barics or 2 10" circular subs and I'm really happy with my decision on buying these L7's! They bump just as hard as my friends setup with 2 12" subs. I'm glad I decided to buy these subs, the low mounting depth is a huge plus! Buy these if you are lacking space, it doesn't get better.

Very good and loud speakers, my son loves them.

Very high quality construction, good appearance. Speakers were very easy to install.

Like it

Great sound and low noise. Easy to install and clean looks.

Class D full range?

After reading online about the issues faced by high frequency reproduction and class d technology I was skeptical whether these amps would perform well at high volume/high frequency. While my setup may not be quite audiophile grade, the addition of this amp has definitely brought it up a peg.

Seeing the Polk class D would run cooler and take up less space for the power, I bit the bullet and ordered. I am a believer now! This amp sounds great! While my Infinity Kappa 6x8's have always been a little on the bright side, they play much smoother than the other amps I've tried. Also, after playing the system at near full volume for 2hrs, the amp barely gets warm. Awesome!

May or may not be audiophile grade, but for anyone with a half way decent setup (aftermarket amps and speakers) will most likely be satisfied! I wouldn't let the amp class decide for you, get to your local audio shop and test one out today!!

By the way, did I mention the band-pass filter with the x10 multiplier? I think Polk just got a new #1 fan!!

P.S. I have only heard about Polk durability... gave it 5 stars
Settings have no graduated marks ... 4 stars

INCREDIBLE

I ordered this amp on a decision that it is cheap and has the 500rms I wanted. Plus I feel Polk Audio brand should be good enough to do the job.

Man...I was wrong. IT DID ONE HELL OF A JOB!

Obviously 500rms means power, but it isn't just SPL that this incredibly small Polk Audio amp provides; it provides superb subbass definition I have since long forgotten! I admit I wasn't expecting such a high sound quality out of this amp, but hearing is believing and this amp delivers! My subwoofer is AVI Sound SLS300, a high end subwoofer that once upon a time was paired with DLS Ultimate amp. This baby Polk did just as good if not better thanks to the higher power rating. It is just incredible.

Build quality is awesome too. It feels well made and solid with a nice weight to it. The piano black finish is gorgeous, and connection is very very good. The size? My goodness it is a blessing. The price? Ummm, if I said it I fear Sonic will jack up the price!

I suggests one thing for all of you guys wanting a high quality amp be it for front speakers or subwoofer; buy this amp!

I cannot say about reliability, but thus far I never blown an amp so maybe it is down to installation. Hell, why not, I just gonna give it 5/5 because this product truly impressed me.

Thank you to Sonic Electronix for the awesome delivery too!

Crisp and clean and unreal amounts of power in this tiny package.

I bought this with the PAD1000.1 for a new install. Driving a set of SR6500's. I have never had these speakers sound so good. Auditioned with some Duffy, Adele and then to see how they handle a pounding, some Five Finger. Nice, tight midrange and the vocals are breath taking with this new D series amp. Like the other PAD, this amp runs COOL over a long long period. The clarity of this amp is just nothing short of amazing. The SR6500's really shine with this amp. Did I mention how tiny this thing is? You can install it anywhere. Same heavy duty 1/0 accepting power connection and a beautiful finish. State of the art in all aspects. This amp cannot dissappoint.

Strong amp

Strong amp and low distortion. Great specs. Very clean power. I liked it so much I ordered a second to drive another pair of speakers. It drove alpine 50c so strong I had to put 60c in the back on the same amp. Nice connection posts. Solid and secure. Small footprint nice controls and the daisy chain ability of input output is handy. Seen the same amp under another brand for more money. Sonic price makes it easy to get into a good amp and shipping was crazy fast.
