I haven’t yet heard Eminent Technologies fan type subwoofers, but they are very expensive and require an additional two add on rooms for cabinets. Acoustic loading shall further extend the low frequency response.
The half-space reference efficiency shall be 2. 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. The best box is no box infinite baffle.
JBL continually engages in research related to product improvement. 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.

Your can also get an answer there.
Subwooffer with JBL H. All times are GMT 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.

Subwoofer JBL H specifications.
To achieve this performance, the H incorporates a new diecast aluminum frame, integrally stiffened cone with foam surround, mm 4 in diameter edgewound copper ribbon voice coil, and individually machined magnetic pole piece and back plate.
It sure sounds great, though. Jlb specifications of a typical production unit shall be as follows: Adjust your pampers accordingly.

Is there anybody who has built a big enclosure for a ? Always fun learning more 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.
Usable frequency response shall extend from 20 Hz to 2 kHz. Highest Recommended Crossover Frequency: Voice Coil Winding Depth: Rated power capacity shall be at least W normal program material.
The frame shall be of cast aluminum to resist deformation, and the magnetic assembly shall utilize a ferrite magnet and produce a symmetrical magnetic field at the voice coil gap. The sensitivity rating of JBL low frequency loudspeakers is based on a signal swept from Hz to Hz.
For this reason, any current JBL product may differ jlb some respect from its published description, but will always equal or exceed mbl original design specifications unless otherwise stated.
