Polk Audio DXi691: Clean and Precise Sound




Klippel Motor Optimization:

The DXi691 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. This model is equivalent to the popular db691.



Proprietary Dynamic Balance Technology:

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.



What does Marine Certified mean?

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.

Speaker Specifications

Series
This is the manufacturer product line of speakers.
DXi (Polk)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6" x 9"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
3-way
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Soft Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1"
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Aluminum
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Dynamic Balanced polypropylene
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
300 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
100 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
93 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
35 - 22000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
3-1/8"
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Yes

Polk Audio 6 x 9

September 16, 2016

Replaced some 16 year old speakers with these, am quite happy with the great sound, ordered another amp and bigger speakers so we could here the radio under the pontoon boat as well as in it. Was quite surprised to find great sound through the floor and under the boat without having to add more speakers. When the back speakers fail, will replace with more of the Polk Audio

Great speakers for the price

August 1, 2016

I previously had these and accidently blew all four not thinking correctly while hooking up amplifiers for them.. I bought my second pair here and finally got them running with proper power and tunes decently. They get loud with maintaining pretty good SQ. They also take bass slamming at 141db very well from the trunk
