Typical Response and Impedance Curves, Enclosure
Volume and Port Tuning
Frequency response contour of the 2241H taken in a hemispherical
free-field environment, a closed box of 280 l (10 ft 3) internal volume
enclosing the rear of the driver. Measured response of a typical pro-
duction unit, including all peaks and dips, does not deviate more than
2 dB from the above curve. The dotted line represents measured 45
degree off-axis response. The dashed curve represents the response
when the driver is mounted in a 280 l (10 ft
3) vented enclosure tuned
to 30 Hz using a port with an area of 320 cm2(50 in 2) and a length of 20 cm (8 in). The impedance magnitude curve is measured in free-air.
Distortion vs. Frequency
Distortion levels raised 20 dB, measured at 60 watts, 1 meter.
With very high thermal power handling, special atten-
tion was paid to increased mechanical integrity. A new
cone design which greatly improves cone strength allows
for increased reliability and longer life. Greater linear
excursion for matched power and displacement levels was
achieved via a new surround topology and edge damping
treatment. The 100 mm (4 in) voice coil benefits from a
new winding technique which offers greater thermal sta-
bility with increased power handling. All elements of the
cone, voice coil and suspension system have been careful-
ly optimized and controlled to ensure smooth high fre-
quency response.
The 2241H is ideally suited for use in touring and fixed
sound applications where high SPL and deep bass
response are required. Its low distortion and smooth
frequency response make the 2241H suitable for critical
monitoring applications as well.

the gap vents to allow sufficient air circulation and proper cooling to take place.
