Average Customer Review(s):
Nice good bass beats pretty hard , not a common name but worth the money.
Got two of them and the enclosure in a bundle deal. Good deal for the price.
Pros: Good price. Good woofers.
I got two of these subs in a "Bass Package", that included a dual ported box. They look very clean and appear to be well built. I'm currently running them on an older amp with 200 rms to each sub. They sound great, but I have not yet pushed them to the limits of the amp. So far so good. I would recommend these subs to anyone looking for a budget system without sacrificing quality. Just a warning: you will need an allen wrench or better yet, a hex key drill bit to install these subs into your box. I only had an allen wrench so it took me awhile to get these installed in the box.
Pros: Quality, fit and finish. Sound great so far.
Cons: Need allen wrench or allen key drill bit to install.
Sound good at an affordable price
arrived in record time and in great shape, is working fine in my speaker cabinets I purchased almost 40 years ago!! The woofers are awesome!!
Great speaker for the price.
Great Subs that provide really tight bass as well as hitting those good low ends. I was surprised at the bass delivered in such a small space as my 03 2 door jeep tj.
Pros: Really punchy bass, good delivery of low end notes, not a lot of air space required
Always the best speakers,put them in a redone 88 f150,sound great as always, this wasnt my first polks and wont be the last.
Pros: Good price,great quality,great sound
I listen primarily to Hip Hop, R & B, Dubstep, Reggae and Hawaiian and in their dual sealed box they perform outstanding. If I want to I can flex the roof and windshield of my car no problem. I would not however recommend them for a beginner to car audio because they have very little distortion around their rated power which to the beginner is perceived as lower output. Creating a tendency to turn up the gain, bass boost and volume to compensate. So if you want to slap these might not be the best for you. If you care about the details of my setup and how I use them to make my system sound great read on... The pair of DB1240's is connected to a Boston GT-2200 amp hooked up with 4 gauge power and ground 1.2 farad Tsunami cap in the trunk of my Mazda 3 sedan. They are getting a rated 900 watts rms to the pair so factor in voltage drop and it's more like 800 rms so around 400 watts rms to each, ballpark. If you have a good quality amp and set your gains properly and don't clip your signal they will handle more than their RATED power and excel. The bass is tight and detailed dropping to pick up low rumbling sub bass sections while still being able kick you in your chest on higher notes and even picking up a nice hum on mid bass to blend with my front sound stage. Throw these on a quality amp and tune it correctly and you will be happy. 4 stars because well only the Funky Pup subwoofers could ever really achive a true 5 star rating...
Pros: Sound Quality, Clean simple design, powerful, directions come with recommended X-Over settings for sub as well as front soundstage.
Cons: Quick slides, allen wrench screws
Once I had the subs installed I was happy that I finally had some 'hit' back into my stereo, however the hit was not as I wanted. I listen to music that has some soft hits that my past subs would have picked up and slammed on however these subs don't pick up the little hits and that was what I was looking for....
I purchased this sub to replace an old Pioneer I had, and it sounds great! I'm into jazz and old school R&B, this sub brings out the best in this type of music. Crutchfield, really came thru.
very nice thank you keep up the good work!!!very fast shipping
I recently damaged my Powered 12" JBL Northridge 8 ohm Home Audio Woofer and replaced with this 4 ohm Polk db1240. The JBL Northridge has a 250 watt rms, 550 peak power 8 ohm amplifier but, this Polk woofer matchs up perfect and sounds great!
I purchased these with the recommendation by a Crutchfield advisor and I am very pleased. I put these in an airtight enclosure built to the manufacturers recommended size and I am pushing them with a 600 watt amp. I am not disappointed. I replaced a blown pair of 10 inch and these Polk Audios blow them away. Thank you Crutchfield for another fine product. My Crownline boat sounds awesome and I get a lot of compliments on the quality of the sound system.
Pushing this with a 150 watt home amp (AC powered of course) it WILL and does, push it to it's max. In a box with isolation spikes all sealed but the 10" X 4" port. 1.3 cu ft. Other things I use , Denon reciever, Polk monitor 50's front and back... sorry I forget the model, center channel w/ 2 5 1/4's. Never go out and buy a powered sub unless you want quality. So easy to make a GREAT one yourself!
This sub beats all the subs in its categories hands down . I had a pioneer 126 DVC sub in my car along with two JBL GTO 0937 Speakers . I was very hesitant to get this sub installed ,however on recommendations of my dealer i got it installed and i think it was worth it . Amazing punch and bass. Very Clear sound . It gives the punch and does not make too much noise distortion . I love this sub and think is gr8 value for money . Definate buy .

Polypropylene Cone: The cone is made with polypropylene, which provides durability while being lightweight and rigid. The cone is supported by a vented cone/coil coupler, which stiffens the cone for greater mechanical stability and lower distortion.
Santoprene Surround: The Santoprene surround is resistant to extremes in temperature, humidity, and exposure to sunlight for excellent long term reliability.
NOMEX Spider: The fire-retardant flat NOMEX Spider allows extended linear motion while providing highly reliable mechanical and thermal stability.
Triple-vented Kapton Voice Coil Former: Triple venting of the 4-layer Kapton Voice Coil Former, Cone/Coil Coupler and Pole Piece contribute to the high power handling and reliability of the db Series subs.
Klippel Laser Analyzed: The Polk db woofer's voice coil alignment, motor, and suspension are optimized using a state-of-the-art Klippel laser analyzer for superior cone travel linearity, resulting in a flatter response with lower distortion.
Break-In Period: Polk db subwoofers will achieve even greater performance once they are thoroughly broken-in. To break in a new db Sub, play music through it for 20 to 30 hours at moderate levels.
Marine Certification: Polk speakers are marine certified, making them a good choice for boats in fresh water, convertibles, motorcycles, ATVs, and other applications where the speaker might get wet. Because they have coated steel baskets and the terminals are not covered, we do not recommend using them in salt water environments.
Recommended Sealed Box Volume: Polk recommends mounting this woofer in a sealed enclosure made out of 3/4" MDF with an internal volume of 0.88 cu/ft.
Recommended Ported Box Volume: Polk recommends a ported enclosure made out of 3/4" MDF with an internal volume of 1.50 cu/ft using a 4" diameter x 10" long port.
Recommended Bandpass Box Volume: Polk recommends a bandpass enclosure made of 3/4" MDF with a total internal volume of 2.15 cu/ft. The bandpass box should have a 1.0 cu/ft sealed rear chamber and a 1.15 cu/ft ported front chamber with a 4" diameter x 12" long port.
