Joseph Audio - RM22XL
PRICE FROM $5,000.00
Manufacturer's Website
The slender RM22XL takes the performance of our famous
RM7XL and makes it even better. Midrange transparency, bass extension and
imaging are all improved, and the sand fillable cabinets take up no more space
than a pair of ‘7s on stands.
The RM22XL delivers the spaciousness previously associated with panel speakers,
but with the superb image focus of a mini monitor and dynamics of a full sized
speaker. In fact many panel speaker owners have traded up to the RM22XL, finding
the virtues of their old panels matched with the additional capabilities of the
22's.
The RM22XL's sound is made possible by several key Joseph Audio technologies:
• Metal cone woofer - Aluminum cones are extremely rigid, resulting in very
clear dynamic sound free from the common midrange resonances that mar the
performance of conventional plastic or paper cones. This woofer is equipped with
an extended pole piece that acts as a "phase plug" extending the usable
dispersion of the woofer at the top end of its range, and displacing any
resonances that could form inside the cavity of a conventional dustcap.
• Dual Section dome tweeter - These latest generation sonatex dome tweeters
offer sweet smooth extended highs, without any of the "oil-can" resonances found
in metal domes. The result is a natural sounding treble range that reveals all
the detail and beauty of the music.
•Asymmetrical Infinite Slope crossover
the patented Infinite Slope Crossover virtually eliminates the interactions
between the drivers, so the sound that comes from the woofer is separate and
distinct from that of the tweeter. It also optimizes the sound of each the
drivers, permitting the use of such exotic materials as aluminum cones, while
effectively silencing the ringing that such drivers can exhibit in conventional
implementations.
* Sand fillable Silent Box enclosure
The RM22XL is also very easy to live with, the sand fillable enclosure is only
8.5" wide and 10.5" deep, with a very small footprint, and its clean classic
lines fit in with a wide range of decors without dominating the room. Available
from $3499 in Black, Cherry (shown) Maple, and Rosewood finish.
Quotables
"DAMN GOOD! ...the new metal cone line beats all... hits the nail on the head in
terms of combining bigtime detail and a listenable tone." - Marlon Ben Feld,
Chief Editor, GoodSound
"Clear, sweet, and articulate. Airy, dynamic, and uncolored. Hologrpahic,
precise, and non-fatiguing. Their left-to-right, front-to-back, top-to-bottom
soundstaging is damn near electrostatic in its immensity, yet the speaker sitll
has the snap, crackle and pop of a traditional two-way dynamic design." -

SPECIFICATIONS:
Sensitivity: 86 dB SPL, with 2.83 volts RMS
@ 1 meter, 4 pi (anechoic).
Sensitivity combined with impedance indicates how much amplifier power is
required for the loudspeaker to play at satisfying volume levels. When comparing
this spec to low impedance (4 ohm) designs, you must add 3 dB to the figure,
since 4 ohm loads draw twice the current from the amplifier, providing the
illusion of greater sensitivity, while placing more stress on the amplifier’s
power supply. The moderate sensitivity of the RM22XL indicates that even smaller
amplifiers can achieve realistic levels in all but the largest rooms.
Impedance: 8 ohms nominal, 7 ohms minimum.
System impedance indicates whether the speaker presents a "hard" or "easy" load
on the amplifier. True 8 ohm speakers are less amplifier and cable sensitive,
and partner well with a broader range of amplifiers, including tube designs.
Crossover: 2-way Patented Asymmetrical Infinite Slope Crossover at 2 kHz.
Constructed of specially selected components, woofer and tweeter crossover
circuits are physically independent. Provision for bi-amping or bi-wiring. Each
network is tested and calibrated to a high degree of precision, resulting in a
virtually perfect match to the original design prototype.
The steep filter slopes ensure good acoustical behavior in the crossover
regions, with a minimum of acoustical interference, along with low distortion
and wide dynamic range. Driver acoustic responses are in-phase throughout the
crossover region.
Frequency Response:
The RM22XL delivers a very smooth and even response over a very broad listening
window. Unlike conventional low order crossover designs, the speaker retains its
sonic balance over a wide angle both vertically and horizontally. This results
in a higher level of fidelity than a simple on axis measurement can reveal.
Listening window response: within 2dB from 38 Hz to 20 kHz.
