Up for sale: I have one pair of brand-new-in-box gold / copper-cone Mark Audio's Alpair 10.3 (10M) looking for an appreciative new home.
The Alpair 10.3 is a 5 1/4in / 100mm wideband driver with a magnesium-alloy cone. Middle-Q, long-throw suspension to handle LF dynamic peaks, 88dB 1m/w sensitivity [nearly], 38.2Hz Fs, shallow cone profile for enhanced off-axis dispersion, arrestor to prevent over-excursion. One of Markaudio's most popular and flexible drive units. Full spec. here: Alpair 10.3 | Markaudio
I'm asking £90 for the pair, plus shipping.

Sorry for the dumb question but I am not really familiar with FR drivers...

You can use it as a mid-tweet on a baffle (or a box speaker for that matter). Flexible driver.
