Considered by some to the end-all be-all
reference speaker, the Wilson X1/Grand Slamm stands six feet high and weighs in at a
whopping 600 lbs. each! This speaker uses one 1" forward firing tweeter, two
3/4" rear-firing tweeters, and two 6" midranges in the upper portion of the X1.
The rectangular lower portion holds one 12" and one 15" driver for lower
frequency support. Frequency response is claimed as an amazing 19.5 Hz to 22.5 kHz
while sensitivity is a high 95 db. Rumors abound that this speaker works amazingly
well with lower wattage single-ended tube amplification. Minimum amplifier power is
claimed as 20 watts per Wilson Audio.

other then the longstanding and very popular Klipschorn corner loving speaker. With

This very unique design is from the folks
at MBL. Seen here is the "D" version of the 101. This is a very
unique four-way system using very unique ribbon technology that are mounted to produce a
360 degree soundfield around the speaker. The speaker uses tweeter, midrange, woofer
high, and woofer low to give a full frequency response of 20 Hz to 40 kHz. This is
all rated at 4 ohms with a sensitivity of a very low 81 db/w/m. From personal
experience i can tell you that these babies need at least a 250 wpc amplifier and
benefit from 500 watts on up! Each speaker weighs in at around 175 lbs. by the way.

Here is the original and critically
acclaimed version of the Royal Reference 3A speaker called the Master Control. These
Swiss made high sensitivity 92 db/w/m minimonitors feature a 8" carbon fibre
mid/woofer that has a unique center-mounted phase plug. Meanwhile, a very high
quality 1" silk soft dome is used for the uppermost frequencies. An extremely
simple, two part 6db crossover is also employed. The phase response is claimed as
being almost constantly flat at +-5% while the frequency response is 44 Hz - 20,000
The VMPS Special Ribbon Edition of the
Super Tower III use four woven carbon fiber 12" woofers in one tower, one 6"
free swinging monopole ribbon in the other. An outboard crossover is also
supplied. The bass can be driven with over 600 watts while the mid/tweeter panel
maxs out at "only" 300 watts. Since even the larger photo leaves the true
scale of these babies to be wondered, the dimensions of these large towers are 76" x
19.5" x 17" (HxWxD) for the woofer and 75" x 4.5" for the mid/tweeter
panel. Total weight when crated, 500 lbs. Bring a friend!
