Sony XS-GS1720

Two-way design

The Sony GS series speakers deliver incredible frequency response with outstanding dispersion and beautifully clear highs thanks to the MRC woofer, soft dome tweeter and integrated 2-way crossover.

Sony XS-GS1720

Aluminum dome tweeter

The GS series speakers feature a synthetic fabric soft dome tweeter to deliver incredible high-frequency response.

Sony XS-GS1720

6-1/2" MRC woofer

The GS series woofers use Mica Reinforced Cellular (MRC) fibers for supremely light and extraordinarily rigid woofer cones. MRC woofer cones produce exceptional musical transients with little distortion compared to traditional cone materials.

Sony XS-GS1720

Integrated crossover

GS series speakers use precision crossovers to match the frequency response capabilities of the drivers. The 2-way, 5000 Hz crossover feature a 12 db/oct high-pass filter (HPF) and 6 dB/oct low-pass filter (LPF) to ensure smooth music transitions.

Sony XS-GS1720

High energy magnets

The GS series speakers use high energy magnets to control cone travel and power handling. The midrange woofer uses powerful Ferrite magnet while the aluminum dome tweeter uses rare earth, compact Neodymium magnets.

Sony XS-GS1720

Bi-amp design

Bi-amp speaker systems use separate power inputs for each component of the 2-way speaker system. This lets you drive the speaker system with dedicated power for the High Pass (HP) and Low Pass (LP) channels instead of sharing the power.

Speaker Specifications

This is the manufacturer product line of speakers.
GS (Sony)
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.
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.
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.
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.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

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.
Mica Reinforced Cellular Glass-Fiber
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
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.
160 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.
75 watts
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".
86 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).
45 - 32000 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
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-1/2" x 5-1/2" 
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.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Fredericksburg, VA

I bought these for installing in a friend's car and they were fantastic! I bought a third set of them for another friend's car. Stickers on the rear fall off however, which can be annoying. Other than that, these are the best for the price I've dealt with.

Frankfort, IL

pretty decent

November 17, 2014

These speakers are definitely pretty good. Good price, good design, and not bad sound. Definitely better than stock I'm my chevy sonic. Mounting was easy as pie, and they are definitely louder. I do regret not spending more and getting better ones. If you're looking for just some better everyday speakers, these fit the bill for sure. If you really want a loud system, spend more money and get high quality

Excellent Product, Value and Service

January 30, 2014

I was not sure when I ordered this product but SONIC came through with the right radio and speakers for my Silverado and for 1/2 of the price of the retailers. I got my order Super fast and it gives my music the clarity it needed to rock my world. I just today ordered more speakers for the rear of my Silverado. Love Sonic. I trust them and will continue to use them for my Audio needs.... They know what they are talking about and are rteliable and honest.

What the best 6×9 speakers for 2012 Chrysler 300?
A shopper on Jul 31, 2014
Best Answer: I actually bought the sony xs-gs1720 which is a 6.5 speaker. It is a good quality speaker. Very claen and clear highs with decent lower frequency reproduction. Also the option of angling the tweeter is a nice feature tnhat helps in staging sound. But as far as a 6x9 i do have the infinity kappas. They have been awesome. Very clean clear highs with very goodbass response. I highly reccomend that 6x9!

what speakers do i need for 03 Jetta gls sedan tdi?
A shopper on Nov 21, 2014
Best Answer: The Sony GS-1720 speakers should fit your 03 Jetta but you will need to make a speaker bracket adaptor. Not too difficult if you have the right tools. As far the sound goes, they were pretty tight upon installation, but the sound field opened up as they broke in. I powered them Alpine 4x45 watt amp and it was plenty.
