Available in 8-inch, 10-inch, 12-inch, and 13.5-inch woofer sizes. TW5: JL's only shallow mount subwoofer and only available in 13.5-inch. The mounting depth is a mere 2.54 inches. This subwoofer features 3-ohm nominal impedance and has an RMS of 600 W. Easily mounts in tight places. [16]
Subwoofers use speaker drivers typically between 8-inch (20 cm) and 21-inch (53 cm) in diameter. Some uncommon subwoofers use larger drivers, and single prototype subwoofers as large as 60-inch (152 cm) have been fabricated. [38] On the smaller end of the spectrum, subwoofer drivers as small as 4-inch (10 cm) may be used.
American EIA standard RS-299A specifies that (or DCR) should be at least 80% of the rated driver impedance, so an 8-ohm rated driver should have a DC resistance of at least 6.4 ohms, and a 4-ohm unit should measure 3.2 ohms minimum. This standard is voluntary, and many 8-ohm drivers have resistances of ≈5.5 ohms, and proportionally lower for ...
It is air cooled, features protection circuitry, and is capable of around 300/350 watts RMS safely into 2 ohms. The 2 ohm load rating is very stable (this amp actually operates at less than 2 ohms), enabling the use of multiple mix and match speaker systems to improve acoustic efficiency and sound stage options.
A horn-loaded speaker can have a sensitivity as high as 110 dB at 2.83 volts (1 watt at 8 ohms) at 1 meter. This is a hundredfold increase in output compared to a speaker rated at 90 dB sensitivity and is invaluable in applications where high sound levels are required or amplifier power is limited.
