Frequently Asked Questions - GTX691PRO BLAUPUNKT
What are the main features of the Blaupunkt GTX691PRO?
The Blaupunkt GTX691PRO is a 6x9-inch 3-way coaxial speaker with a power handling of 80 Watts RMS and 400 Watts peak. It features a polypropylene and mica cone, rubber surround, a 25 mm tweeter, and a 100 mm midrange driver for clear, detailed sound.
What is the difference between RMS and peak power handling?
RMS (Root Mean Square) power is the continuous power a speaker can handle safely, while peak power is the maximum burst power it can endure for short moments. The GTX691PRO delivers 80W RMS and 400W peak, so it can handle dynamic audio peaks without distortion.
Can I connect this 4-ohm speaker directly to my aftermarket car stereo?
Yes, the GTX691PRO has a 4-ohm impedance, which is standard for most aftermarket car stereos and amplifiers. You can connect it to a head unit or an external amplifier rated for 4-ohm loads.
What is the recommended amplifier power for the GTX691PRO?
The ideal amplifier output is 50 to 150 Watts RMS per pair. This range ensures the speaker receives enough power for good performance without risking damage from clipping or overdriving.
How do I install the GTX691PRO in a 6x9 speaker opening?
The speaker fits a standard 6x9 inch opening. The recommended cutout is 155 x 215 mm with a mounting depth of 75 mm. Secure the speaker using the included screws and ensure the mounting surface is flat and stable.
Are these speakers weatherproof for marine or outdoor use?
The GTX691PRO is designed for car audio environments, but it features a rubber surround and coated cone that offer moderate moisture resistance. However, it is not fully weatherproof and should not be exposed to prolonged heavy rain or submersion.
How do I clean and maintain the Blaupunkt GTX691PRO?
To keep the speakers clean, use a soft, dry cloth to gently wipe the cone and surround. Avoid using water or harsh chemicals, as they could damage the material. Regularly check that the mounting screws remain tight and the speaker is free from dust.
What is the warranty period for Blaupunkt car audio products?
Blaupunkt typically offers a 2-year warranty on car audio speakers from the date of purchase. The warranty covers manufacturing defects but not damage from improper installation, misuse, or accidental damage. Keep your proof of purchase for claims.
Do I need an external crossover for these speakers?
No, the GTX691PRO is a coaxial speaker with a built-in crossover. The 3-way design includes internal components that separate frequencies for the tweeter, midrange, and woofer, so you can connect it directly to an amplified signal without additional crossovers.
What is the mounting depth and will it fit my car?
The mounting depth is 75 mm (3 inches) from the mounting surface to the rear of the magnet. This compact size allows installation in most vehicles with standard 6x9 speaker locations, such as rear decks or door panels. Always check clearance before installing.
