AERの製品の中ではMD1B,MD3Bが低音が良く出ます。
特にMD3Bをお勧めいたします。
MD3Bは高額ですが、AERでは一番売れているとのことです。
世界一のフルレンジといっても過言でない!!とメーカーは言っています。
AERからのメールです。
MD3B is smoother and finer and more detailed and more dynamic.
MD3B is absolutely wonderful
フェイズプラグを何故つけないか?
高域がファンタステックな音にならないとのことです。
いろいろな材質(砲金、チタン、銅、黄銅、真鍮・・)でテストはしたようですが、
無い方が一番音質は良いとのことです。
Feastrex driversのデザインからすると 、一見間が抜けて見えますが、
実物をみるとサブコーンも大きく 、これはこれでなかなか良いデザインと思います。
MDシリーズはbdシリーズに改名。

AERのお勧めはMD1,MD1B,MD3,MD3Bです。
Lowtherアルニコタイプは磁石が大きくなるほど音が悪くなる(現在販売店の評価/PM6Aが一番音は良い) とのことですが、AERは磁石が大きくなるほど音質は良くなります。 AER, F.Keller 氏からのメールです。 the high regíon of the MD drivers sweet and soft absolutely phantastic Bass is extremely well. ★Keller氏は昔,Lowtherで開発をしていた方のようです。 Lowther driverの長所、欠点も分かっています。 |
MD1
AERとドイツの2社、日本の1社がFront partsを使用して励磁型を開発していましたがMD3,3Bの音質を超えることができず販売を断念しました。(かなりの高音質でした。)

MD 3
The AER MD 3 uses our strongest and biggest rare neodymium magnet. The ends of the air gap where as a matter of principle magnetic distortion are created are very far away from the voice coil. The magnetic field is driven into saturation and stretched very long in a homogenous way. Pole plates and pole piece are dimensioned that way that a especially flat rising of the impedance curve towards high frequencies is guaranteed.
The neodymium magnet by means of thick pole plates is protected against electromagnetic fields. It is characterized by a high cross section and by its very low electrical impedance. All magnetic field lines are used for the motorisation in the centre-near area of the air gap. Voice coil and diaphragm of this loudspeaker are capable to do excursions of 7 millimetres without leaving the full transmission area of the magnet.
This drive unit is designed according to the AER Formulae and shows an extreme flat frequency response curve, particularly showing a very high efficiency in the highest highs. It is especially designed for big front loaded horns with highest efficiency. The horns have to be able to support the drive units in the low frequency and mid range area and need to have exactly the same efficiency as the drive unit itself. For that reason they should have a very high acoustical impedance towards lower frequencies. By means of its special design-characteristics the magnetic inductance of the MD 3 was increased again and the field strength of the magnet was risen dramatically resulting in an even higher efficiency that is making the system to an ideal front horn drive-unit..
For that reason this loudspeaker should only be used in
AER
horn systems for example the
AER
EXCenter Horn in the following called AER EXCH. Used this way the
AER
MD 3 in our opinion is the summit of the physically and acoustically
possible. Listening to the
AER
MD 3 a tremendous and beautiful mid range is spread crowned by a
fantastically brilliant soft and mild high and super high range -far up to
the supersonic range.
Music by that is getting an absolute extraordinarily plastic figure so as if
you could pick single tones out of the music. In combination with a powerful
subwoofer system listening music is getting a tremendous adventure.
The MD 3 fascinates you with an extreme full and warm sound and truly
explosive and eruptive dynamics, a breath taking never heard before
resolution and is extreme rich in musical detail
MD 3B
Great Vintage Loudspeakers社のAL2WVL(AER Frontparts 使用)励磁型(1ペア45万円)の音質はかなり良いのですが、MD3,3Bクラスの音質を超えていません。
The
AER MD 3B
is a comparatively new AER
design the stands for a bass. In this unit a very large rare neodymium disc
magnet is used.
And therefore in comparison to the MD 2B besides a slightly risen efficiency
especially dynamics and attack could be improved again. The magnetic field
is very long and homogeneous in the whole air gap.
The pole plates are dimensioned in a way that the neodymium magnet is protected against magnetic field distortions of the voice coil very well. It has a very high cross section area and inside a low electrical impedance. Along the whole air gap length all lines of the magnetic field are used for the transmission of force. The widened air gap allows an excursion of the moving membrane of 10 millimetres without leaving the linear motorized area also at tremendous impulses.
The
MD 3B
was intentionally designed as a real fullrange drive-unit to get a
controlled base. It is designed according to the modified
AER
Formulas and appears with a very flat frequency response curve and a reduced
high efficiency. The high mass of the whole magnetic construction guarantees
an extraordinary stability of the sound stage.
The MD 3B is designated for the use in front loaded and back loaded horns.
By means of the stronger and lager magnet compared to the smaller B- models
it has again increased dynamics, improved resolution and its ability to
differentiate is so extreme that it is also especially designated as a mid &
high range unit. Its special destination is in the use as a fullrange
drive-unit.
In comparison to the other B-models the MD 3 B shows an even stronger and
more mighty base that spreads full forces - the use of a subwoofer is
obsolete. For the mentioned reasons the MD 3 can reproduce astonishingly
levels in the bass range.
Build into the
AER
Acoustique or
AER
Acoustic you get an increase in the level below 100 Hertz up to 8 db.
Listening to the MD 3B an extraordinarily balanced and beautiful mid range
is crowned by a fantastically glowing soft and mild high & highest range,
widely ranking into the ultra sonic.
Music gets a realistic and truthful plastic shape as if someone could pick
out the single tones. Listening to music will get an impressive experience.
The MD 3B fascinates you with very full and explosive dynamics, a up-to-date
never heard resolution and richness in acoustical detail.
