Review of the Sony XS-GS1720 and XS-GS1720S speakers

In the 1950's, I'd take the family television's vacuum tubes down to Willow Grove Radio and TV Repair, check them with the giant tester machine, buy new replacement tubes, and reassemble the repaired television, so my mom and dad could enjoy their precious, respectively, Dean Martin and Red Skelton shows. In the 1960's, I studied radio and electronics at the Franklin Institute in Philadelphia. After college, in the early 70's, I joined a rock 'n roll band as the soundman, learning how to operate the electronics that make music sound good. Then, I worked in a music store in Austin manufacturing, installing, repairing, and operating sound systems and components for recording studios, nightclubs, and touring bands. I moved back to Charlottesville permanently in 1984 and opened a little demo recording studio. I also attempted to put to practical use the creative writing degree I had picked up along the way. In 2006, I finally came to my senses and got this job at Crutchfield where they actually pay me to ramble on, rant, and explain the things I love about music, electronics, and getting good sound.

Sony XS-GS1720 coaxial speakers

Recently, I took a pair of Sony 6-1/2" GS 2-way coaxial speakers, the XS-GS1720, and a set of GS components, the XS-GS1720S, into the Crutchfield Labs and gave them a listen. I played four different songs, in their entirety, switching back and forth between the coaxials and components, and took notes on how well I thought they handled the highs, mids, lows, staging, and imaging of the music.

Listening in the Crutchfield Labs

Over all, these speakers performed very well, reproducing the music clearly with no glaring defects in the sound. In fact, I thought both the components and the coaxial speakers exhibited a remarkable coordination and smoothness in the midrange to mid-bass region, where the vocals and guitars play. The musical imagery, the characteristics of each instrument, was precise and clear. The staging, or the aural illusion of each instrument's relative position on a stage, was excellent and wide for both the components and the coaxial speakers.

The component set seemed a bit fuller in the vocal range than the coaxials, because the component tweeters sounded brighter than the coaxial tweeters and that brought the vocals out front better, especially on the female voice on the Country ballad I played. On both that song and the percussive Rock instrumental I played, the acoustic and electric guitars stood out crystal-clear with pleasing timbre, and no harshness.

I didn't expect much bass from 6-1/2" woofers, but I was pleasantly surprised by the hints of bass that did emerge in the Afro Beat and Chicago Blues songs I listened to. It's not bad, really, but if you're a serious bass-head, you'll want to add a subwoofer along with these speakers. All the drumming and percussion on the recordings sounded crisp and clear.

These 2-way coaxial and the component speakers, both rated for 75 watts RMS, will sound their best when powered by an aftermarket amplifier rather than a receiver alone, due to their relatively low sensitivity. But once set singing, these speakers play smoothly, and with good definition.

Check out these Sony GS speakers and use our vehicle selector to see if they'll fit your car.

    I have a pair of SONY GS 6921 in the rear. DO you recommend 1720 coaxial for front? How will be the bass? Will I need a sub?

    Milad, I can't recommend those speakers because I don't know if they'll even fit in your car or not. If they do fit in, they'd probably sound fine with those other Sony speakers. As far as bass goes, any car audio system will get better bass with a subwoofer than it would without one.
