GENERAL PRODUCT DESCRIPTION
Since the introduction of the Voice of the Theatre®
loudspeaker
system in 1945, Altec Lansing’s 515 series have been the leading
low frequency loudspeakers in cinemas and auditoriums all over
the world. The 515 is truly legendary, and Altec Lansing’s 515-
8HHP and 515-16HHP are the two newest models in this series.
Continuing in the tradition of the 515 series, these two new
models produce the outstanding fidelity that established Altec
Lansing as the number one choice in theater, auditorium, and
studio applications.
The 515-8HHP and 515-16HHP are constructed from one of the
industry’s largest magnet structures mated to a very lightweight
cone assembly, resulting in two of the most efficient low
frequency loudspeakers that Altec Lansing has ever produced.
Both low frequency loudspeakers incorporate a high-power
handling, edge-wound aluminum, flat-wire voice-coil, which is
designed for dependability and high acoustic output level
capability. These low frequency loudspeakers also feature a
special cloth suspension, which provides extended low frequency
response and extremely high linearity. The new 515-HHP series
loudspeakers are designed to maximize the performance of bass
horn enclosures (vented or sealed).
The 515-16HHP is rated at a nominal 16 ohm impedance, making
it the first choice for dual-loudspeaker, vented bass horn
cabinets, like the Altec Lansing 210/211 and 817A enclosures.
Installation of these low frequency loudspeakers is made simple
with 0.25-inch blade type wire terminals, allowing either solder
connections or crimp type quick-connect wire terminals.
The Altec Lansing models 515-8HHP and 515-16HHP are perfect
complements to our high frequency compression drivers when
the requirements are superior efficiency, excellent low frequency
response, premium sound quality, high acoustic output level, and
absolute reliability.

ARCHITECTS & ENGINEERS SPECIFICATION
The loudspeakers shall be multi-purpose, 15 inch / 381 mm
low frequency cone drivers. The loudspeakers shall have an
operating bandwidth of 40 Hz to 5kHz with a sensitivity
of 104 dB when measured at a distance of one meter.
Their power handling capability shall be 200 watts AES
(800 W peak). Their nominal impedance shall be 8 Ohms
and 16 Ohms, with a minimum impedance of 7.9 Ohms
and 15.8 Ohms at 600 Hz. The magnetic gap of these
drivers shall have a flux density of 1.5 T, resulting from an
8.25 lbs. (3.74 kg) ferrite magnet. Their nominal free-air
cone resonance shall be 37 Hz and their voice-coil shall be
3 inches (76 mm) in diameter of edge-wound aluminum
ribbon. The loudspeakers shall have dimensions of 16
inches (406 mm) in diameter and 6.69 inches (170 mm) in
depth, and shall weigh 30 lbs. (13.6 kg). The low frequency
loudspeakers shall be Altec Lansing models 515-8HHP and
515-16HHP.
FREQUENCY RESPONSE AND IMPEDANCE MAGNITUDE OF 515-16HHP IN 828G
As we are continually striving to improve Altec Lansing products, specifications are subject to change without notice.
Please visit www.altecpro.com for the latest information on Altec Lansing Professional products.
1 The frequency response of the loudspeaker system is measured at a distance of no less than 3 meters to obtain full range data. The level is then corrected to be
equivalent to a 2.83 V 1 m measurement. A near field measurement of the loudspeaker system is performed for frequencies below 500 Hz. This data is then
combined with the full range measurement to give an accurate composite frequency response curve.
2 The limits of the frequency response are referenced to -10 dB of the systems rated sensitivity in a 828G vented enclosure.
3 The sensitivity of the loudspeaker system is the log based average SPL taken over the intended bandwidth of operation for the system with a 2.83 V swept sine
stimulus. The data is measured and level corrected in a manner consistent with notes 1 and 2.
4 The power handling capacity of the loudspeaker system is tested using a full range form of AES Standard 2-1984. The test stimulus is band limited (40 Hz – 16
kHz) pink noise with a 6 dB crest factor. The applied RMS voltage is determined using the minimum impedance of the system. The amplifier used to drive the
system has a minimum operating headroom of 6 dB referenced to the RMS voltage.
5 The peak output level of the loudspeaker system is calculated based on the sensitivity and the peak power handling capabilities of the system.
6 The minimum impedance of the loudspeaker system is taken over its intended band of operation.
7 The distortion measurements of the loudspeaker system are performed at a distance of 1 m with RMS input voltages corresponding to 1% of rated system power
handling calculated using minimum system impedance. The distortion percentages are log based averages from 300 Hz – 3 kHz.
