Frequently Asked Questions - T925A FOSTEX

How do I connect the Fostex T925A speaker to an amplifier?
Use the screw-type binding posts on the rear panel. Connect the amplifier's speaker output to the terminals, ensuring positive to positive (+) and negative to negative (-). For best results, use banana plugs or bare wire securely tightened.
What is the ideal placement for the T925A speaker?
Place the speakers on sturdy stands or shelves at ear level when seated. Keep them at least 30 cm from the back wall to avoid bass boom. Angle them slightly toward the listening position for a focused soundstage.
How should I clean the speaker grille and cabinet?
For the cabinet, use a soft, dry, lint-free cloth to remove dust. For the grille, gently vacuum with a low-suction brush attachment or wipe with a slightly damp cloth. Avoid liquid cleaners on the drivers.
Is the T925A magnetically shielded?
The T925A is not magnetically shielded, so avoid placing it directly next to CRT televisions or old monitors to prevent color distortion. It is safe with modern flat-panel displays.
What type of amplifier is recommended for this speaker?
A solid-state or high-quality tube amplifier rated between 20 and 80 watts per channel is ideal. The 8-ohm impedance and 88 dB sensitivity make it easy to drive with most home stereo receivers.
Why is the sound distorted at low volumes?
Distortion at low volume often indicates loose wire connections or a faulty amplifier. Check all speaker cables and ensure the binding posts are tight. Also confirm the amplifier is not clipping due to an incorrect input source.
Can I use the T925A in a home theater system?
Yes, the T925A works well as front, center, or surround speakers in a home theater setup. Use identical models for the left and right channels to maintain tonal consistency. Pair with a subwoofer for deep bass.
How do I replace a blown tweeter in the T925A?
To replace the tweeter, remove the grille and the screws securing the tweeter. Disconnect the wire, install the original Fostex replacement tweeter, and reconnect carefully. Contact Fostex or an authorized dealer for the exact spare part.
Is there a break-in period for new T925A speakers?
Yes, new speakers typically require 20 to 50 hours of playback at moderate volume to reach optimal performance. During break-in, the suspension loosens and the bass response becomes more natural.
How can I identify the positive and negative terminals on the T925A?
The positive terminal is usually marked with a red ring or a '+' symbol, while the negative terminal is black and marked with '-'. Use the same polarity on both speakers to ensure proper phase coherence.
