This allows you to quickly focus on what matters: powerful, clear sound. With an efficiency of 98 dB, the performance unfolds even at moderate amplifier settings.
The high efficiency of 98 dB in the Competition GZCF 6.5XSPL-NEO means that the speaker achieves a remarkable volume even with relatively low amplifier power. This is particularly convenient if you want to upgrade your existing sound system without having to install a huge amplifier. You will notice how confidently and clearly the highs and mids come across, even when you are not pushing it to the limit. This is especially advantageous for fans of loud music, as the sound is rich and details do not get lost. Additionally, the speaker can handle up to 250 watts of maximum load, providing extra reserves when you want to turn it up. This way, you can enjoy an impressive musical experience in your car for as long as possible.
Especially when you often park your car outside or it sits in the blazing sun during the summer, you benefit from a UV-resistant speaker. The materials of the Competition GZCF 6.5XSPL-NEO remain stable longer due to this treatment and do not lose their flexibility as quickly. This is particularly important for maintaining sound quality and long durability. Water-repellent properties are also a significant advantage, especially in humid conditions from rain or high humidity. Often, some water gets inside the vehicle when windows or doors are open, which could damage the membrane. However, with this model, concerns in this regard are reduced. Thanks to the fiber-reinforced paper membrane and special coatings, your speaker remains sound-wise fit and robust, even when you drive your car through all weather conditions.
