    In modern music the demand for bass is practically insatiable. It is rare to find a concert or club venue that doesn’t run their bass cabinets at very high levels. The B-Zero Motiv Bass Horn reliably and consistently provide extremely high levels of clean, usable, undistorted musical bass output.

    Providing high-impact, high-efficiency bass response from 35Hz to 200Hz with superior clarity and definition, the B-Zero Profundo Subwoofer is a single 18″ bass cabinet featuring a folded tractrix horn enclosure. The B-Zero is a very efficient and hard-hitting horn-loaded bass cabinet. It uses a relatively low compression ratio to minimize horn coloration. The result is a natural, open sound characterized by a heavy hit. The B-Zero is very effective for reproduction of extremely dynamic musical material.

    In contrast to direct radiating systems, the dynamic detail, the impact or “punch” is better resolved with a horn. The ability to resolve this aspect of the sound is due to several factors. Compared to a direct radiating system, when horn loaded a driver can produce an equal sound level with a shorter excursion. Shorter excursions tend to require less power and less acceleration and also produce less distortion from the motor and suspension systems.

    Designed to deliver the necessary sound pressure level using minimal excursion, the B-Zero can produce greater resolution of detail and lower levels of distortion. In addition to these benefits, the directivity afforded by the horn focuses the energy and impact toward the audience more effectively than a direct radiating system. While these attributes are generally true of all horns, the B-Zero takes full advantage of these benefits without suffering from the maladies that plague many other horns.

    The B-Zero maintains a remarkably smooth response and exhibits very little of what might be called “horn-honk”. The B-Zero Subwoofer doesn't interfere with the perceived clarity of the overall system because they have extremely low levels of distortion. While this is measurable even at low levels, at higher levels, when other boxes begin to stress, the difference can become very noticeable.

    In short, the B-Zero is a remarkable loudspeaker, which has been in production for 10 years and still remains a favorite with both old customers and new, consistently eliciting praise for its sound quality and output capacity every time it’s played. It certainly is a contender as one of the loudest and most efficient bass horns on the market along with extraordinary subjective sound quality.

    To design a horn loaded cabinet that is able to reproduce truly low bass it has to be quite large. However, where horn loaded cabinets tend to be bigger than their direct radiating counterparts, the trade-off is that you generally require fewer horn loaded cabinets and considerably less amplification to reach your equivalent sound pressure level goals.

    The B-Zero is intended for use in multiples. Like all horns, they benefit from being coupled together so the best results will be achieved when at least two or more cabinets are coupled together.

    The use of high efficiency horns in a relatively compact radiating area can also provide for wider and more consistent coverage than a larger number of conventional cabinets, particularly in the upper bass region where the wavelengths can be shorter than the array dimensions. A smaller radiating area will tend to produce a more coherent wave, and affords the widest and furthest coverage possible. ­­For this reason, horn-loaded systems can be ideal for use with long-throw systems like line arrays.

    Engineered to work hard and continue to work where others fail. The BASSBOSS warranty provides 6 years of coverage against defects in materials and workmanship. The warranty DOES cover failed drivers, including burned voice coils, for 2 years from the date of purchase. If a voice coil, or anything else, fails within the warranty period, replacement parts will be provided without charge. (See warranty documentation for complete details). With the peace of mind afforded by plentiful, clean, undistorted output and comprehensive protection systems, you can confidently push the B-Zero Subwoofers to levels and depths that would otherwise require more or bigger cabinets.
