Frequently Asked Questions - JS6904 JENSEN
How do I connect the Jensen JS6904 speakers?
Use speaker wire to connect the spring clip terminals on the back of each speaker to the corresponding positive and negative outputs on your amplifier or receiver. Ensure proper polarity (red to red, black to black).
What amplifier power is recommended for the JS6904?
An amplifier rated between 20 and 100 watts per channel at 8 ohms is ideal. Avoid underpowering or overpowering to prevent distortion or damage.
Can I place the JS6904 speakers on a bookshelf?
Yes, their compact size (300x200x250 mm) and bookshelf design make them suitable for shelves or stands. Keep at least 15 cm from walls for optimal sound.
How should I clean the speakers?
Wipe the vinyl finish with a soft, dry microfiber cloth. Do not use water, solvents, or abrasive cleaners as they may damage the surface.
Can I use these speakers outdoors?
The JS6904 is designed for indoor use only. Exposure to humidity, rain, or extreme temperatures can damage the components and void the warranty.

Jensen provides a 1-year limited warranty against manufacturing defects. Keep your purchase receipt as proof of purchase.
Where can I find the user manual?

Can I connect a subwoofer to these speakers?
Yes, if your amplifier has a subwoofer output, you can add an active subwoofer. The JS6904 will handle midrange and highs, while the sub reproduces low frequencies.
Is there a break-in period for the speakers?
Speaker break-in is debated, but playing them at moderate volume for 20-30 hours is often recommended to loosen the suspension and achieve smoother response.
What should I do if there is no sound from the speakers?
Check all connections: ensure speaker wire is securely inserted, amplifier is powered on and not muted, and source is playing. Test with another speaker to isolate the issue.
