    • They make my hair move...sound really great when tuned. And make people angry at will.
Size: 12" - Dual 4 Ohm
Bought 2. Setup in 1Kw 4 ch stereo setup. 2 ch for l&R subs. 2 ch L&R mids highs. For reference music, aka old people moosak. Placed speakers in a dual L&R ported, single passed enclosure. With separate tuned section for mids tweets. The subs ring sweet and mellow on symphonies and bang Space Wizard like a champ. I wanted stereo! love the nice left right hit you get from independent subs! I cant say enough for the Skar value! I know these are value line, not the hiline powerhouse speakers.. But in a ported enclosure. Tuned, crossed and setup. They SHINE! The speakers at 250 watts each are so fricken loud you need earplugs for anymore power. But sound 100% on point NO distortion, butter FAT! Exactly like they should. Yes I can go 500each...why? No one would stay in car with me! They would hit me in anger and leave lolz! Even at half volume i get the are you serious looks . Me- Hey sorry! I may be old, but I too like it loud. He He, think I built it all for you old farts? P.S Observation on humanity! Volume that hurts for one song, a moment later is too low for a favorite song. Derp! ... show more

    • Best 12" sub for the money.

Review Image by Joseph Bragg Joseph Bragg
The media could not be loaded. This Skar audio SDR 12-in D4 wired in parallel to 2 ohms and is 600W RMS and I'm only pushing 350 watts into it and it is so loud it hurts my ears being right behind the driver's seat in my Silverado. It was decently priced and even better when they go on sale. I used to have the IX 12-in D4 wired to 2 ohms as well and this speaker blows the other one out of the water with its deep lows and impressive loudness. Definitely worth giving it a try for a budget subwoofer it performs phenomenally. I can only imagine after the break in period. Definitely worth picking one up or two for that matter depending on your setup configuration. One is definitely plenty for me where I have it located. It shipped really quickly as well and I got it on time with my free shipping Amazon prime. Just remember to break it in respectfully. Skar audio recommends a minimum 24-hour break in. At half to low volume and at half too low power just to break them in properly. I only drive about an hour a day so it won't take me close to 24 days to break mine in but once they're broken you can crank up the wattage and the volume and they will sound amazing. I know my IX12 sounded amazing and over 2 years later still performs well. I put the IX12 in my wife's Kia forte and she loves it and it thumps really hard. My point being is if they're properly broke in they will last as any speaker should if properly broke in and properly powered with clean power. ... show more

    • Punchy Bass and Solid Build!
Size: 12" - Dual 2 Ohm
This Skar SDR-12 hits hard! The 1200W max power really pumps out deep, clean bass that shakes the whole ride without distortion. Dual 2-ohm voice coils give me flexibility with my amp setup, which is awesome. Build quality feels tough and the design looks sharp in my enclosure. If you want loud, tight bass that doesn’t break the bank, this sub’s a winner. Definitely recommend for anyone serious about sound! ... show more

    • Bang for the buck.
Size: 15" - Dual 2 Ohm
I had 2 10" Skar IX series in the trunk area of my Odyssey and they just weren't cutting through when the windows were down. But I had had them for a few years and they were reliable and sounded great, so when I saw the the level up (SDR) 15" for $120 I jumped on it. No problem hearing the bass now. Unbelievable the difference between the 2 setups with the same wattage, same amp. Low budget Blaupunkt amp (200W rms-ish) is driving this thing with ease. I listen to a lot of metal that can be really hard on subs with the distortion, but this thing laughs at that. Digs deep for modern hip hop too. Never owned a 15 before and regret not switching earlier. 3 Cuft sealed box. Boom. ... show more

    • Nice Build, Nice Bass.
Size: 10" - Dual 2 Ohm
Really heavy duty, well built sub, for the price. Handles Rated RMS. Sounds good, Its not Jl-Audio, But its really good for the price. Best sub in my opinion for under hundred dollars. This has nothing to do with the subwoofer itself. but the Only thing I didn't like was the Skar Warehouse is literally 25 minutes from me. But this subwoofer shipped from TEXAS, when it could have shipped from 15 miles away. Seems like such a waste of resources shipping this subwoofer to amazon warehouse in Texas, from the warehouse 15 miles away, Then, shipping it to me, It traveled over 2400 miles to make a 15mile trip. Well, its US trip at least. You would think they be a better way to handle shipping. Hopefully they were just out at the other distribution centers, I hate to think this is how it usually works. Great subwoofer, It likes to travel. lol ... show more

    • Highly reccomend
Size: 12" - Dual 4 Ohm
Despite what some people think about skar audio, they are amazing for the price, bump HARD, and have been totally reliable so far. I haven't had any issues with it at all except for it being a little smelly after having it full tilt for a minute (its just because i am severely underpowering it with an 800 watt amp). The sub looks great, and its got some good power to it ... show more

These speakers are amazing! They are hefty speakers and can really pound. I have two of these hooked up to a Skar 1200W amp, and they are able to shake the mirror off of my corolla! I have been using them consistently over the past two years and haven't had a single issue with them burning out, breaking, tearing, cracking, or anything. I put basic rail covers over them to protect them from other objects and have them tuned so they aren't clipping, if you have any of those happening any damage is 100% on you. These are part of the reason I have tinnitus, but I will never regret it. You won't feel like you are balling on a budget with these! ... show more
