Frequently Asked Questions - T900A FOSTEX

How do I connect the Fostex T900A speakers to my amplifier?

Turn off your amplifier, then connect the positive terminal of the speaker to the positive output of the amplifier and the negative to negative. Ensure the impedance selector on your amplifier matches the 8 ohm rating of the T900A.

What is the recommended amplifier power for the T900A?

The T900A is best driven with 20 to 100 watts per channel. Using an amplifier with slightly higher power than the speaker's rating is acceptable, but avoid continuous high-volume playback to prevent driver damage.

Can I place the T900A on a bookshelf or should I use stands?

Bookshelf placement is acceptable, but for optimal stereo imaging, use sturdy speaker stands so the tweeter is at ear level. Avoid corners, as bass can become boomy.

How do I break in new Fostex T900A speakers?

Play music at a moderate volume for the first 20-30 hours. This helps the driver surrounds and suspension loosen and stabilizes the frequency response.

How do I clean the speaker cabinet?

Use a soft, lint-free cloth slightly dampened with water. Do not use volatile solvents like alcohol or benzene, which can damage the finish.

Can I use the T900A in a home theater system?

Yes. The T900A is a fine front or rear channel speaker. Ensure the receiver's crossover setting is appropriate (e.g., 60-80 Hz) if used with a subwoofer.

What is the impedance of the T900A and will it work with my A/V receiver?

The nominal impedance is 8 ohms, which is compatible with most receivers and amplifiers designed for 8 to 16 ohm loads. Check your receiver's speaker impedance selector.

How do I bi-wire the T900A speakers?

Remove the metal jumpers between the two sets of binding posts. Connect the tweeter and woofer terminals separately to two amplifier channels or use two runs of speaker cable. This can reduce interference between frequency bands.

What maintenance is required for the Fostex T900A drivers?

Keep the drivers away from dust and moisture. Use a soft brush to gently clean the grille and cone. Do not touch the dome tweeter; it is delicate.

Is the T900A magnetically shielded?

The T900A does not feature magnetic shielding. If placed very close to a CRT television or magnetic media, it may cause discoloration. Use a shielded subwoofer or keep at least 30 cm away from magnets.
