SOUNDSPLINTER - Ignition Series RL-I8
High Excursion Audiophile Component Bass Subwoofer
Welcome to the home of SoundSplinter's RL-i Ignition Series
subwoofers. These drivers have been designed as an economical
solution for those seeking audiophile-quality bass response, utilizing
low to moderate power levels, for either the home or car audio
environment where space is at a premium. Rare for small drivers, the
RL-i makes use of a high-excursion design engineered for maximum
throw and linearity. Featuring thick gap-plates, a solid steel t-yolk,
custom cast aluminum basket, NBR rubber surround, aluminum
shorting ring to reduce distortion, gold plated spring-action terminals,
including a stiff anodized spun aluminum cone heat sinked to a 2"
diameter voice-coil in addition to woven lead wires to eliminate the
possibility of annoying and potentially harmful tinsel lead slap.
Big things do come in small packages! Our exclusive 8" subwoofer is
perfect for serious enthusiasts seeking phenomenal performance,
especially in applications demanding commanding bass involving limited
space. RL-i 8" driver offers obscene one-way linear excursion potential of
over 18 millimeters, as well as the ability to handle up to 500 watts of
input power. Truly a driver able to contend with - and in many cases put
to shame - similar drivers that cost twice as much.
Our exclusive 8" driver is perfect for serious enthusiasts seeking
phenomenal performance for any application involving limited space. We
have designed this driver to perform in enclosures as small as 0.2 cu ft
net volume. Coupled with the obscene one-way excursion potential of
over 18 millimeters, as well as the ability to handle up to 500 watts, the
RL-i8 will be able to contend with and in many cases put to shame, similar
small drivers that cost twice as much! Available in dual and single 4 .Quite
probably one of the best 8" drivers available on the market today, the
RL-i8 is a versatile subwoofer suitable for almost any application. Small
enough to fit into tight spots for car audio, yet powerful enough to pump
a small to medium sized home theater full of clean and accurate bass
response. This woofer will provide for impressive output coupled with
extremely low higher-order harmonic distortion, making for a crisp sound
that will be music to your ears!
High-Force Motor: Utilizing the b = (BL)2/Re ratio in our design for the
motor, we have been able to refine the winding width of our voicecoil in
relation to the gap height which has resulted in a motor that yields 50%
more force than the typical design approach. b is a true representation of
force versus excursion, providing much greater use than the Xmax
Thiel-Small parameters traditionally used to evaluate woofers.
High Excursion Surround: The NBR rubber surrounding material connecting
our aluminum cone to its basket has been engineered using non-linear
finite element software. This has provided for an incredibly stable,
symmetrical surround that does not cavitate, even under high internal
enclosure pressures. The result? Low distortion and high reliability.
Unique Spider Technology: Our spider technology was also designed with
non-linear finite element software, allowing for high performance,
symmetrical, and reliable spiders. We know that high excursion has
caused conventional tinsel leads to slap the cone or spider at modal
frequencies, creating unpleasant sound and physically damaging the
driver. To null this effect, our tinsels are woven discretely into our spider.
Symmetrical Magnetic Field: Our large high-energy ceramic magnets,
designed with the aid of special software has maximized productive
magnetism while minimizing the necessary amount of steel and mass
used.The extraordinary symmetry of the magnetic field above and below
the gap-plate ensures very low distortion.
High Power Voicecoil: In order to provide force on the cone throughout full
excursion of our drivers, we know that the voicecoils used must be quite
long. A long voicecoil also has a relatively long thermal time constant
which ensures very high power handling capability.
These woofers offer a very high (BL)²/Re of 70 in addition to a relatively
low Qt value, performing best in small sealed enclosures in the car audio
arena or larger sealed enclosures for home audio. The motor topology
used in the creation of these drivers has been hailed as an industry
leader in extremely low distortion, especially at very high powered low
frequencies. It is also considered to have an extended top end for a
subwoofer, providing for an extremely smooth transition to a midbass
driver.
All RL-i series drivers feature thick gap-plates, copper shorting rings to
reduce intermodulation distortion, gold plated spring action terminals, a
stiff aluminum cone doubling up as a giant heat sink, and woven lead
wires for a higher quality product. Renowned for outstanding performance
and low distortion, the these drivers are wonderful for use in any
application requiring clean and accurate bass.
