もう１つスパイダーを一部だけお見せします。超特別品ですがどうです！皆さんお持ちのダンパーをもう1度見比べてください。私はその薄さと精度の高さを触って実感してきました（Alpair７、12も一緒です）。Revc= 3.600 Ohm

Please remember these are pre-production results from 2 sample units. Provided the beta testers like the sample drivers, I normally expect to get the mass production units close to the samples. All the same, there’s likely to be some small variations in the results so bear this in mind – thanks.
But with the 6s it seemed much clearer which we all preferred.
Having said that it was an interesting test as we tried one of the drivers (the copper cap one I think) in two different cabinets. One looked like a small ported box – the brown, driverless pair in the front of the photo above. It was beautifully made and sounded pretty good, but the other (on top of the stand in the photo) sounded much better. It was vented at the base so looked like a small version of my Pencils but Mark said there was a baffle inside too. This produced a much fuller sound that was really impressive for such a small driver without making it sound at all muddy or bloated.
Comparing the two versions of the 6s was then done using the vented cabinet. We started with the copper cap version and I was surprised at how good the sound was. It was nicely balanced with decent bass and clear treble and would be perfect for a high end small office/room/desktop system.
When we swapped to the no copper cap version I found the results a little disappointing. The higher frequencies were quite rolled off so it seemed rather flat. Compared to typical commercial speakers of it’s size I’m sure it would score very well, but having just listened to the cap version it really didn’t sound very special at all. (Sorry, Mark!).
On the Alpair10s I could see a good reason to produce both models but, personally, for the 6s I felt the copper capped version sounded so much better than the non-capped one that I’m not sure it would make sense producing both. Maybe there are different setups or applications where the non-capped version would have an advantage, but in the setup we used (the vented box with a lower power tube amp) I would definitely choose the capped version.
現在Alpair６および７を自作バスレフで楽しんでいます。
Alpairの対称性に拘った設計にはいつも感銘をうけており、自作Boxも内部上下に設けたバスレフダクトを後方中央で合体させて開口すると云った、これも対称性に拘った構造にしています。ダクト開口を後方にした理由は中高音の漏れで音が汚れるのを少なくするためです。
New Alpair６の発売を楽しみにしております。
メタルのAlpair６が復活するとの情報ですが、ある程度変更が加えられるのでしょうか？
お問い合わせありがとうございます。
Alpair６のニューモデルはコーン、コイル、Tヨーク、ダンパーは全部新しい設計です。
ペーパーバージョンがCCAW、メタルがカッパーコイルです。
開口径は現行と同じですので、是非試して下さい。
ディストーションが極めて少なく、クリアーなサウンドは絶対に感激されると思います。
alpair10も9月末でしょうか？
Alpair1oも9月最終週に製造10月には日本に輸送販売ができる予定です。楽しみにしていてください。
私だけ、世界で1人Alpair10G2のプロトタイプを毎晩聞いています。へへ・・・。
