The 15NCX750H is a 15" neodymium coaxial transducer designed for use in compact reflex enclosures and stage monitors as small as 40lt with a nominal dispersion of 70 X 50 degrees.
97 dB LF / 109 dB HF SPL 1W/1m average sensitivity
Single magnet neodymium motor
800W LF - 240W HF maximum program power handling
75 mm (3") Interleaved Sandwich LF Voice coil (ISV)
Aluminum Demodulating Ring (SDR) for minimum LF distortion
60 mm (2.4") HF pure Titanium diaphragm
Edge-wound Aluminum ribbon HF voice coil (EWAL)
HF copper sleeve for reduced distortion and higher output
Smooth on/off axis 70° x 50° response
Suitable for compact enclosures and stage monitors
The curvilinear profile LF cone provides smooth response within its intended frequency range thanks to its high damping pulp composition. The 75mm (3in) LF copper voice coil employs Interleaved Sandwich Voice coil (ISV) technology, in which a high strength former carries windings on both the outer and inner surfaces. This results in a balanced coil with a uniform distribution of mass and motive energy and an extremely linear motor assembly. The low distortion and sound quality are further improved by an aluminum demodulating ring (SDR technology) that flatten LF impedance and phase with constant power transfer.
Equipped with a proprietary hybrid radial tangerine phase plug, the integrated HF compression driver has been designed to give a smooth, coherent wavefront at the horn entrance in all working frequency ranges with an high level of manufacturing consistency. The phase plug, with its short openings and high flare rate value, assures low distortion and remarkable improvements in mid-high frequency reproduction. A copper sleeve reduces inductance value above 10kHz, improving phase and impedance linearization.
The 2.4" diameter HF diaphragm assembly uses a high strength, high temperature treated Nomex voice coil former joined directly to the titanium diaphragm on its upper bend edge, assuring extended frequency energy transfer. This improves linearity and shows unparalleled reliability when compared with a straight former joint. A specific HF exit profile design has been chosen in order to maximize the cone's profile coupling.
The high force neodymium single magnet structure makes the 15NCX750H a lightweight speaker for its performance class - only 5.1kg (11.25 lb).
The XO15NCX dedicated passive crossover filter is provided, making this neo coaxial speaker a ready-to-use transducer system.
Due to the widespread use of high power audio systems at outdoor events, the ability to perform in adverse weather conditions is an additional key feature of the 15NCX750H. This has been achieved using exclusive cone and magnet plate treatment processes which increase resistance against corrosion and make the cone water repellent.

Bonjour, est-ce que le filtre XO15NCX fait partie du prix? Est-il disponible séparément et à quel prix.
Pouvez vous fournir un plan de caisse idéal?
Cordialement,
Bertrand Fleuret
Response:
Le filtre n'est pas compris dans le prix du haut-parleur. Le haut-parleur 15NCX750H est fournit seul.
Le filtre passif dédié "XOVER 15NCX750 - XVR15XCR00 - 03715XCR00" est disponible séparément (voir référence FI-15NCX750).
Bertrand on 10/25/22
Merci.
Quelle caisse est conseillée? Une caisse style 110L avec évents ø10x10 pourrait-elle convenir.
Response:
A première vue une charge bass-reflex de 66 Litres accordée à environ 51 Hz devrait apporter de bons résultats.
Nous ne proposons pas de simulation de charge, nous vous conseillons de vous munir d'un logiciel comme WinISD pour simuler votre propre charge.
Bertrand on 10/25/22
Merci, je vois qu'il est out of stock, il était en stock ce matin? J'y réfléchis.
Response:
Vous devez confondre avec le 15NCX750 qui lui est en stock.
Pour les questions de prix et disponibilités merci d'adresser votre demande par email ou via la page contact du site.
Bertrand on 10/25/22
Ok vous avez raison.
Je suis sur Mac et n'ai pas Winsid, 66L serait bien, si il vous étais possible de me donner le volume d'évent je commanderais avec filtres.
Response:
En après vente (après expédition de la commande) nous pouvons confirmer cette information gratuitement. En avant-vente, cela est un service payant que nous proposons sur demande par email.
This system is only available for technical questions. For questions of prices, availability of products and deadline thank you to send your request by the contact page.
