CHP-70 Audio Drivers
The CHP-70 is an all new paper cone full-range audio driver from Markaudio. This driver is the first in a new technology line that has a unique low-mass design and cone. The “engineered” approach was applied by its designer, Mark Fenlon who passionately believes in making all critical components to a very tight specification.

• Wide range: 66Hz ∼ 20kHz
• Excellent linearity for this driver class
• 0.57 Qts suits most many system designs
• New technology, low mass paper cone
• Tight tolerances, ±5% for all batch drivers
• Colour co-ordinated design

Paper Cone
The cone is the first of its type to be integrated into a production process known as Multi Form Mass Reflex, a Markaudio technology that delivers “aerospace” tolerances during manufacture. Other performance critical components were reviewed and upgraded.

Looks Matter
The CHP-70 boldly integrates all major components to offer a visually colour co-ordinated driver. System builders now have an excellent opportunity to make interesting designs that break away from the older, more typical design box styling.

Pure Music
A very robust bass for this size of driver. Middle and high–range delivery is accurate and detailed. New technology, excellent performance and modern styling combined at an affordable price. The outcome is “pure music”.

Rear Suspension
The rear suspension (spider) is made from a newer form of material that delivers a close control over the excursion of the driverʼs movement.

Cap
The cap to coil bonding process is also a feature, and uses adhesive from aerospace bonding technology.

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. 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 higher density coating that increases the mass of the cone and produces a pre-determined pattern of control on rigidity. The result is a driver with a very sweet character in the middle and high range that retains musical detail.

Features
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.

The Alpair 6 is an ultra-high performance full range driver delivering audiophile performance in a compact size. The Alpair 6's low range capability is better than many larger drivers. The clarity and detail from this driver will amaze listeners. The lower middle range is particularly good. Vocals sound real giving that concert tone to the performance. This driver is ideal for smaller full range audio, desktop, multi-media and multi-driver applications.

The Alpair 7 is a rare (possibly unique) driver in this size and class. Its primary feature is its extended high range, operating to 30-kHz the Alpair 7 eliminates the need for a tweeter. The driver achieves this performance without using a whizzer or co-axial centre tweeter. The Alpair 7 is a purist single cone/cap design.

This driver incorporates a new cone multi-forming technology originally developed in Japan. The cones are made using 7 separate forming and trimming processes, all controlled via CNC operation. The accuracy of this technology is superior to conventional spun and press methods.

Tadashi Matsubara San, a most experienced senior driver designer from Japan has produced the rear suspension. It is unique and exclusively made for the Alpair 7. Lui Yi Ping from Taiwan is a specialist in front suspension design. He has produced the 7ʼs suspension as the most advanced of its type so far. It is ultra-thin and the production process for this component is all new. The same exclusivity is also applied to the frame, coil, connectors, every part for this driver is unique custom designed.

The acoustic result is remarkable for a driver of this size, delivering outstanding clarity, detail and musical realism.

Features
* Two colour choices, gun-metal grey and classic gold. Drivers are packed in pairs with 2 X 2mm thick seals and 8 X 22-mm long Hex head wood screws.
* Handling Donʼt touch the cone or cap. These are delicate components.
* Running in period The Alpair 7 has advanced suspensions that require careful running in: Donʼt use any kind of artificially generated sound signal. Hours 1 to 20. Low volume vocal and light music, no heavy bass. Hours 21 to 120, gradually increase the volume to normal listening levels and gently introduce rhythmic bass music. Patience and care will bring musical rewards.

Easy Installation
New standard hole M4 metric hole size. The Alpair 7 comes supplied with high quality Hex drive black powder coated wood screws and a 2-mm PVA cabinet seal for easy installation.

The Alpair 10 is an ultra-high performance authentic full range driver. This driver exceeds 20kHz at +80dB! The 100mm cone is made from a new thin-wall alloy for ultra low mass while maintaining stability. The result is a driver that efficiently operates over an extremely wide frequency range for a speaker of this size and type. This driver delivers astonishing amounts of musical depth. The bass response is low and rich while the middle and high response remains strong and detailed. The Alpair 10 is ideal for audiophile uses, multi-media and multi-channel applications where depth, clarity and detail are the main requirements. This driver is very much the enthusiasts choice.

It's all about the bass with this driver. We set out to make this unit to deliver a solid, rich and most of all, a detailed sound without the need to operate at high volumes. The compliance of this driver suits listeners who genuinely love music and require real detail, not simply a low range thump. This is not a rock and roll driver, there's plenty of those already available.

The Alpair 12 is a large full range single cone drive unit (8 inch - 206-mm frame). The primary feature is its extended and detailed range, operating to 20-kHz.
