BMSLA102ND PA-Lautsprecher 389,90 EUR

Neodymium magnet assembly
Perfect acoustical coupling
Smooth frequency response
Very high sensitivity
800 Hz crossover
Extended high frequency response up to 20 kHz

Introduction:

The BMS LA102ND is a high frequency line array transducer, designed to produce a planar wave front from a 8�x1� rectangular throat. It employs a pair of 4552 ND compression drivers coupled to a special dual wave guide containing a common vertical slot to radiate a coherent planar wave front.

The 4552 neodymium drivers are mounted on a mutual aluminium heat sink for increased power handling and reduced power compression.

What is the difference between LA102ND and 4510ND?

While the 4510ND Planar wave driver is a distinctive new transducer engineered to radiate a coherent planar wave front from a rectangular piston without internal diffraction the LA102ND use more conventional wave guide design techniques to reshape the compression driver�s spherical wave front into planar wave front .

Application:

The acoustical performance of the LA102ND is very similar to a pair of 4510ND. The extremely high sensitivity and smooth frequency response from 800 Hz to 20 kHz together with the high power handling makes the LA102ND the best solution for high quality, high SPL line arrays.

Compatibility:

The LA102ND is dimensionally compatible to two 4510ND units coupled together, so the system can be upgraded later.

Two or more LA102ND units can couple together to create virtually continuous line source.

In a conventional full range compression driver the phase plug must be located extremely close to the diaphragm, excursion of the diaphragm is limited and middle frequency performance is compromised. A typical large diapfragm dome compression driver has a limited high frequency response. Over 8 kHz the dome diaphragm breaks up causing resonance and harsh, metallic sound. The patented design of the BMS 4594 is a result of extensive dedicated research and development providing matic improvement in dynamic response, clarity and ansparency. The BMS annular midrange diaphragm covers the frequency range between 300 and 7.000 Hz with a smooth, linear
response. The large diaphragm excursion of max. +/-0,8 mm results in high output and increased power handling up to 1.300 W peak.

BMS 4550 is a powerful 1" professional compression driver that delivers superb sonic quality in a small package. It has an exceptional dynamic range and produces even the most complex music signals with depth and definition.

BMS Elektronik GmbH located in Hannover, Germany is a leading manufacturer of compression drivers. BMS products are used by professional speaker and high-end companies globally.

The patented BMS design remarkably reduces diaphragm weight and inertia. There is no loss of energy required to drive conventional diaphragms. That is why BMS drivers have higher sound pressure level and less dynamic compression than conventional designs.

Neue Wege Konventionelle Hochtontreiber werden seit Jahren unver�ndert nach den gleichen Prinzipien konstruiert. Mit aufwendigen Materialien wie Titan, Beryllium oder Neodym und speziellen Fertigungstechniken versuchen Designer und Techniker, das Klangbild st�ndig zu verbessern und Leistung und Haltbarkeit zu steigern. BMS geht bei der Konstruktion von Hochtontreibern neue Wege, um die Grenzen herk�mmlicher Technologie zu �berwinden. Das Herzst�ck der BMS-Treiber ist die Membran. �bliche Kalottenmembranen ben�tigen eine hohe mechanische Stabilit�t. Sie werden deshalb aus Metallfolien und Kunststoffen mit relativ gro�er Materialst�rke hergestellt. Dadurch weist die Kalottenmembran eine hohe Masse auf, die nachteilige Auswirkungen hat: geringer Wirkungsgrad, verminderte Dynamik, betr�chtliche Verzerrungen und reduzierte H�henwiedergabe. BMS setzt eine Membran ohne Kalottenteil ein, die wesentlich leichter als herk�mmliche Kalottenmembranen ist. Sie zeichnet sich durch au�erordentliche Dynamik und ungew�hnliches Aufl�sungsverm�gen auch komplexer Signale aus. Die Vorteile Das patentierte Design der BMS-Membran f�hrt zu einer beachtlichen Reduzierung der Auslenkung und Massetr�gheit. Energie, die bei Kalottenmembranen zur �berwindung der Massetr�gheit n�tig ist, wird von der BMS-Membran in Schallenergie umgesetzt. Das Resultat ist ein deutlich h�herer Wirkungsgrad. Durch ihren geringen Hub beim Ein- und Ausschwingen verarbeiten BMS-Treiber Spitzenpegel extrem schnell, die Membran kehrt genauso rasch in ihre Ruhelage zur�ck. Das Ergebnis ist eine vorbildliche Aufl�sung und mehr Dynamik. Gleichzeitig verhindern die geringe Membranbewegung und eine doppelt zentrierte Aufh�ngung kritische Partialschwingungen und verringern so Verzerrungen. Die empfohlene Trennfrequenz liegt bei BMS-Treibern erheblich tiefer als �blich. BMS-Treiber sind praktisch unzerst�rbar und k�nnen sogar ohne Schutzschaltung betrieben werden. �nderungen der Membrangeometrie, der St�rke des Membranmaterials und der Schall�ffnungen beeinflussen die Resonanzfrequenz des Treibers. BMS nimmt auf Wunsch entsprechende Abstimmungen vor.
