Subwoofers de Bocina Vs Ventilados
During all my years in the business, I have been on a quest for the ultimate subwoofer. Horn-loaded subs were my preference and I started BASSBOSS originally based on the performance of the B-One and B-Zero horns. We developed a lot of horns over the years, and continue to do so, because horns have a number of desirable and beneficial properties compared to vented boxes. There was, however, just one thing I was always missing from the horn-loaded subs: Really DEEP bass!
Eventually I designed a hybrid box that incorporated a vented section with a long, partially folded horn-loaded section. It was 45″ square and 24″ tall. Although the box was also quite large, heavy and complicated to build, it was smaller and lighter and less complicated than the B-Zero… and it produced massively low bass compared to the B-Zeros. That particular design was really time-consuming to build, so it was impractical from a size and cost point of view. It did go low but the long horn and the vented section still left something to be desired. It didn’t have the dynamic impact that the B-Zeros did, and the box could have gone just as deep and been a lot smaller without the horn section.
In order to deliver both impact and depth I started combining the two types of boxes and found it to be challenging to integrate the two types. I could get the super-deep bass I wanted from the vented boxes and I could get the massive impact from the horns but getting them to line up and do it together took a great deal of time, measurement and experimentation. When I finally got them to work together properly, it was magic! Massive shock impact with a thick, rich depth I’d never heard or experienced from any horn subs alone, especially since they had to at least fit through a door!
Not only do I understand and agree with the love for the impact of horns, I have improved upon it, to make it even more impactful. Think of it this way, if a 160 lb guy (80 kilogram) hit you in the chest with a solid punch, it would be a hard hit, but if that man was 320 lbs (160 kilograms) that hit would move you much farther! Why the reference? To go an octave lower requires four times (4x) the power, and displaces four times the air for the same sound pressure level. If you can extend the power behind that initial hit by an octave, then it effectively hits four times harder because it literally is four times the mass of air behind the hit.
In this case, for this purpose, I’m not using vented subs in the place of horn-loaded subs, I’m using vented subs to extend and improve the impact of the horn-loaded subs.
Done correctly, horns are awesome and wonderful things, but they have limits. There are three factors that essentially limit a horns performance. The first is its length. The horn’s low frequency limit is determined by how long it is, so its length, from driver to mouth, multiplied by 4 is the wavelength below which it is relatively ineffective. For a horn to be effective at 30Hz, it needs to be 112.5”, 9.375’ or 2.86m long. Some people say they have found ways to break that rule but any breaking of that rule involves compromises, and I’m not a fan of compromises.
Las bocinas tienen 3 factores que dictan su rendimiento.
Su primera limitación es la longitud de la bocina. La longitud de trayectoria interna entre el driver y la boca debe ser lo suficientemente larga como para soportar un cuarto de la longitud de onda de la frecuencia más baja que la bocina (o array de bocinas) necesita reproducir. Si la bocina no es lo suficientemente larga, la onda de presión saldrá de la boca mientras el cono sigue empujando hacia adelante y la «carga» en el driver se caerá, perdiendo eficiencia y permitiendo que el driver se hiperextienda. Por lo tanto, una bocina debe ser lo suficientemente larga como para soportar la expansión de la onda en la frecuencia más baja que necesites reproducir. Suponiendo que 30 Hz es tu objetivo de frecuencias bajas, las bocinas que elijas deben tener AL MENOS 2,85 m de longitud.
La segunda limitación es la constante de ensanchamiento. Esto es qué tan rápido o lento el área de la bocina aumenta a lo largo de la trayectoria. Las bocinas de bajas frecuencias requieren un ensanchamiento lento, lo que hace que su construcción sea más complicada cuando se pliega en gabinetes de tamaño razonable. Cuando se diseña una bocina con un índice de ensanchamiento para frecuencias bajas, se debe elegir un continuo entre la eficiencia y el tamaño. La mayoría de las bocinas que se fabrican en un tamaño razonable NO se construyen con una constante de ensanchamiento baja NI un camino lo suficientemente largo. Uno, el otro o ambos están comprometidos. Esto conduce a respuestas picosas y «bocinazos» y una total falta de profundidad en su desempeño. Estos son compromisos con los que no estoy dispuesto a vivir.
This is the point at which the Sub-Mergence system was developed. Its low-frequency component is the ZV28 subwoofer, which extends system response to 21Hz, and its horn component is called the Z5/D. This solution takes advantage of both technologies’ strengths to create a system that offers the benefits of both with the weaknesses of neither. The combination overcomes the limitations of both the boxes and the horns. In the Sub-Mergence system, the cabinets are properly aligned and integrated with each other, so the shocking impact of the horn combines with the extended depth of the boxes while keeping the size and the power requirements reasonable and affordable. The boxes weigh 220lbs each, are the same size and they interlock with each other.
The second is the experience the system delivers. Its the experience of being immersed in the music, submerged in it, swimming in it, being a part of it. Its beyond hearing it. It turns the air into a liquid. Its the transcendence that happens when you fully integrate the senses of hearing and feeling into the experience of music and dancing. For those who get it, its an instant addiction. It takes your breath away, modulates your voice, caresses your skin, moves your clothes, blows your hair and gives you warm chills…. Its what happens when you hear a familiar song and realize there are layers in the music you’ve never heard before. Frequencies below the capability of what you’ve heard before, dynamics above it, textures behind it and subtleties within it.
Such a system will allow you to listen at very high levels and not be in pain. It sounds big and effortless and open. From barely on to dangerously loud, it will be crystal clear at any level and will keep the same character no matter how high you turn it up. It offers tremendous loudness with no compromise in quality. Its intelligently designed so that you have enough headroom that you never force it to strain and distort and compromise the experience of the audience.
With the Sub-Mergence system there is no need for you to have to choose tight over deep or deep over tight or make any compromise. BASSBOSS knows subwoofer systems better than anyone.
And there is also something very big on the horizon! It’s called B.O.S.S Concept and it’s the ultimate realization of the uncompromised subwoofer horn!
