The DXi651 is made with laser measurement technology via the Klippel Motor Optimization for a smooth excursion path at any volume. This creates a more efficient and long lasting speaker that performs great at low or high volumes.
Polk's engineers are able to design out driver and system resonances that cause distortion with the Dynamic Balance technology. The composite cones also feature a stiffness-to-mass ratio that allows the speakers to react to faster transients with finer detail. You not only get clarity, but function and precision.
The DXi Series speakers go through the ASTM (American Society for Testing and Materials) marine testing to become marine certified. The speakers go through two harsh tests: the B117-03 Standard Practice for Operating Salt Spray (Fog) Apparatus and the D4329-99 Standard Practice for Fluorescent UV Exposure of Plastics. The Salt Fog tests exposes the components 95° Fahrenheit and 5% salt solution for 500 hours and the UV test puts the speakers through 8 hours of UV-B light, black body temperature of 60 degrees Celsius and 4 hours condensate water, black body temperature of 40 degrees Celsius. These tests ensure these speakers will last in the harshest of marine environments.
How does Polk Audio improve on their already popular and very well known PA D series amplifiers? With technology advances, Polk Audio has taken their PA D series into the digital amplification arena. This means a smaller foot print, a super-efficient design which allows for lower power consumption and does away with a larger power supply. This allows the new digital PA D series amplifiers to run far more efficiently with lower distortion and cutting or clipping. The new PA D Digital series amplifiers are available in a monoblock, 2-channel, 4-channel, and 5-channel configuration making them accessible for any application. With a height of under 2 inches for all four configurations, these amplifiers also offer a mounting convenience making them practically perfect for any vehicle. All four configurations feature a 4-way protection circuitry and stainless steel hardware that will not corrode, giving the amplifier longevity and a sleek and stylish look. Polk Audio is a known and trusted company and with these new PA D Digital series amplifiers not only are you getting the high Polk Audio quality, you are now getting the quality in a very high and efficient digital range.

Excellent little amp!
I picked this up about 6 months ago, to go along with the PA D1000.1 sub amp.
Pros: it's tiny, powerful and very clean sounding. Nice looking too.
Con: It's a bit more expensive than it's competitors.
If you have the money, do it. I love this thing!

WOW!
Just received my amplifier today and i am just downright impressed by this amp. The size of the 4000.4 is just amazing considering how much power it produces. Hooked it up to some infinity 6x9's and pioneer 4x6's and thought i was going to blow them! The sound was crystal clear, got insanely loud, and sounded a ton better than my old Hifonics 4ch. Another great addition is the 0 gauge power and ground adapters. Great to give this power hungry amp the power it needs. Was skeptical at first because i never bought anything Polk but in the end NO REGRETS at all! If 50 watts rms is not enough for your speakers, upgrade to this amp just be sure you have quality speakers.

So far so good!
Bought this for our river boat, it's installed in the bathroom(no moisture). Ran it in 123 degree temp full volume for an hour, never shut down and was not much above ambient temps. Very impressed...

Great Amp and Service
This amp pushes my JL mx 880's very well. The amp does a great job and no issues what's so ever. Most of all sonic electronic is a great place to buy from.

Dxi 651 speakers
Polk has never disappointed me. The quality of product is much better vs Kenw00d or P10neer. So is their quality control and testing. I like how it came with a foam type of spacer to go between the speaker and door panel- helps reduce vibration kind of like Dynamat would. Some of their speakers I had before had like a spray-on rubber? on back of the speaker frame. Clearer sound always with them.
