Description
This is a replacement HF compression driver built to fit a range of QTX Sound cabinets. It uses a titanium diaphragm and a 1" throat, so it takes over the high frequency duties in the horn section of the speaker. If the top end of one of your QTX boxes has gone quiet or started to distort, this is the part that brings it back.
The driver suits the QR8 (178.210), QR8A (178.202), QR10A (178.203), QT6 (178.400) and QT8 (178.403) cabinets. It handles 50W maximum power and 25W RMS, with a frequency response of 1kHz to 20kHz. The voice coil measures 25mm, and the unit sits at 55mm deep with an 80mm diameter, weighing 0.39kg. Those figures make it a direct swap for the original horn driver, sometimes called a compression driver or tweeter driver depending on where you are.
Fitting is straightforward for anyone comfortable working inside a speaker cabinet. Remove the old driver from the horn, connect the new one and refit. We would always suggest checking the crossover and terminals at the same time, since a failed driver can point to a wider fault. Keep the original mounting hardware where you can, as it usually transfers straight across to the new unit.

Frequently Asked
Which cabinets does this driver fit?
It replaces the HF horn driver in the QTX Sound QR8 (178.210), QR8A (178.202), QR10A (178.203), QT6 (178.400) and QT8 (178.403) cabinets.
What size is the throat?
It has a 1" throat, which is the standard fitting for the horns in these QTX cabinets.
What is the diaphragm made from?
The diaphragm is titanium, which is used for its stiffness and durability at high frequencies.
What power can it handle?
It takes 50W maximum power and 25W RMS, matching the original driver rating.
What is the frequency response?
It covers 1kHz to 20kHz, handling the high frequency range in these two or three-way cabinets.
Is it hard to fit?
No. You remove the old driver from the horn, connect the new one and refit. It is a direct replacement using the existing mount in most cases.
