The JBL Stadium GTO860C possesses great power handling abilities and delivers good audio quality – certainly of the best component 6×8 speakers.
- Good power handling
- Rugged and durable design
- 3-way upgradeable
- Low impedance
- Poor frequency accuracy
- Highs are overwhelming
The GTO860c features an edge-driven design that provides a smooth response and fairly low distortion when playing audio at high volume levels. However, I have to say that the speakers’ ability to reproduce low, mid and high frequencies didn’t really impress me.
The external crossovers are pretty versatile and do a good job of bringing out the details very well. Additionally, you’ll find a tweeter control button on each crossover that allows you to adjust the level of brightness to your liking. Moreover, the crossovers can easily accommodate a 3-way system upgrade.
The GTO860C’s ability to reproduce high frequencies is considerably good since it’s pretty hard for speakers to produce that range. However, it seems to fall pretty short in that category when compared to other speakers in the same price range as the highs it projects are a bit grating and don’t sound that balanced.
The woofer is equipped with JBL’s Plug One+ technology, allowing it to extend the cone to the edge of the basket, which gives you plenty of surface area that translates to good bass quality. It’s also worth mentioning that the woofer has a glass fiber construction which makes it very light in terms of weight and makes it less power-hungry than other traditional materials.
One of the strongest selling points of the GTO860C speakers is their low impedance which allows you to power these speakers with an aftermarket stereo or a factory-installed radio. You can rely on these speakers’ low impedance to use every watt wisely. To maximize your results, try using an outboard amp.
Overall, the JBL GTO series has been around for years and have established a pretty loyal fan base. The series is known for its reliability, high-end power handling, and their fairly good audio quality. It’s just sad to see other newcomers surpass such a gigantic lineup of speakers when it comes to efficiency and quality.
