Alpair 5 Gold
The Alpair 5 is a special driver. It's a single suspension driver with no spider. The design optimizes low range performance. Compared to typical tweeters, the large cone area delivers more detail in the middle and high range. The Alpair 5 is easy to partner with sub woofers and larger drivers, especially the CSS SDX7. It's also useful unit on its own for mini audio and desktop applications.
The copper-gold cone and cap finish uses our "soft" surface treatment. The process delivers a lower density coating that allows the cone to flex more. The result is a driver with a very sweet character in the middle and high range that retains musical detail.
The Alpair 5 is available in 2 colour choices, each having a different effect on sound performance. The differences are explained on our cone colour information page. See the Alpair 5 Grey page for more options.
Much effort has placed in shaping the cone to deliver a flatter response up to 10kHz while retaining its characteristic +9dB gain above 10kHz. The total Q has also been raised to deliver a sharper LF fall-off for easier integration for those builders using sub-woofers. Crossover designs also benefit, as the usable frequency range remains wide and better defined.
- Great detail, smooth, especially in the middle and high ranges.
- Easy to partner with Subs and larger driver, also good for single mini audio uses.
- 50mm ultra low mass mixed alloy cone with multi-coating.
- Ultra wide frequency range (125Hz to 30kHz).
- Wide excursion (4mm one way).
- Ideal partner for the CSS SDX7 woofer.
- A softer, more mellow tone that is more suited to Europe and North America.
