Features that no or few other
racquets have:
- Elimination
of frame protrusion
- Increased
hitting area (enlarged sweet spot)
- Stabilized
frame
- Improved
Response
all of which combined enhance
speed and distance of driving, accuracy and freedom from trauma to the
players arm and albow.

The Dual
Layer Racquet vs. conventional
1.
Elimination of the Frame Protrusion:
Since there are two independent string beds, one on each side of the
frame, the protruding frame is eliminated. The frustrating frame
shot virtually disappears with the Blackburne Double Strung Racquet.TM
2.
Increased Hitting Area:
The BB DS provides a clean hitting area almost double that of conventional
racquets thus increasing sweet spot area. This results in greater
drive and ball speed - - while at the same time eliminating most rim effects
- - resulting in greater consistency.

3.
Stabilized Frame:
The construction stabilizes the frame, significantly lessening the
oscillations, vibrations, twistings and undulations to which conventional
racquets are prone when a hard drive is delivered.
The construction achieves this
[stabilizing the frame] because it turns the racquet into a sort of BOX
while the single strung racquet is more of a SLAB.
4.
Improved Response:
The dual stringbed construction causes the ball to bounce off the
strings with greater speed than with single strung racquets because the
springback-like effect of the first set of strings is reinforced by that
of the second set.
Improved
performance of A Dual Layer Racquet:
- The whole is stronger than
the components.
- Lower frame edges assist in
providing desired spin to the ball without impacting the ball by a high
projection.
- Both string planes are coupled
together through the leverage of the inward rotation of the connecting
frame.
- String plane edge rotates and
temporarily sinks in, thus resulting in less string stretch.
- Strings with less stretch do
not make double contact with the rebounding ball.
- The rear sheet of strings support
the motion of the front sheets of strings, and without touching.
- Two layer frame is not warped
by impact and thus does not waste the warping energy.
