I am not joking, infrasound in large quantities can hurt you. The JBL Model H is a professional quality low frequency transducer designed for use in custom studio monitors or other applications requiring high sensitivity and power capacity, as well as extremely 2245hh distortion and extended bass response.

He built 2 more later on and has 4 in that stack 2245n but I can’t find a picture of his final config right now.

Other loudspeakers will be considered for equivalency provided that submitted data from a recognized independent test laboratory verify that the above performance specifications are met. Is there anybody who has built a big enclosure for a ? The frame shall be of cast aluminum to resist deformation, and 22445h magnetic assembly shall utilize a ferrite magnet and produce a symmetrical magnetic field at the voice coil gap.


A bigger box will get you lower also. Page 1 of 2 1 2 Last Jump to page: On-axis response, measured at a distance of 2 m 6. The half-space reference efficiency shall be 2.

For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated. Usable frequency response shall extend from 20 Hz to 2 kHz. Originally Posted by JeffW. Performance specifications of a typical production unit shall bjl as follows: Continuous program power is defined as 3 dB greater than continuous sine wave power and is a conservative expression of the transducer’s ability to handle typical speech and music program material.

At the bottom of the page, you can see a strip that says “similar threads”.

Always fun learning more Additionally, the cone is coated with an exclusive damping formulation to ensure optimum mass and density.

The voice coil shall be mm 4 in in diameter and shall be made of edgewound copper ribbon operating in a magnetic field of not less than 1. This motor assembly is optimally balanced with a 25 mm 1 in long voice coil and carefully engineered suspension elements to allow maximum excursion linearity with complete freedom from dynamic instabilities. Acoustic loading shall further extend the low frequency response. Originally Posted by quindecima. The best box is no box infinite baffle.

Rated power capacity shall be at least W normal program material. New materials, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy.
