Our newest product -
the RL-p18 - joins the ranks of two of the most affordable, versatile, low-
distortion, high-excursion woofers in our Premium Series line of low-frequency transducers. Known
for their flexibility in accommodating a variety of home and car audio applications in sealed, vented,
and infinite baffle alignments, the RL-p18 steps up with its massive displacement advantage, linear
output, and absolutely stellar value.
Featuring a triple-stacked 215 ounce magnet structure, vented six-spoke cast aluminum basket, 3 inch
voicecoil, aluminum shorting ring, dual 8.5" spiders with woven leadwires to eliminate tinsel-slap while
allowing for long linear throw capability, a new tall-roll NBR rubber surround to increase effective cone
area while accommodating high excursions, and our signature rigid black anodized spun aluminum cone,
including laser etched logo and complimentary rubber gasket and magnet boot - this is one **** of a
massive driver which retains its practicality comin' at ya for around $400!
Now, for the first looks... :hyper:

As with our RL-p15, this big brother 18 will excel in both car and home audio applications.
Sealed alignments should range from 4 cu ft to infinity (with a Q ~ 0.5, infinite baffle for the win!).
Lending itself in strong style to the vented alignment, consider 4 - 7 cu ft net volume in the car audio
environment, with a tuning frequency near 27 - 30 Hz. For those of you in the home, try not to break
any windows when pluggin' this bad boy into a 13 cu ft net volume enclosure @ 18 Hz. :boxer:
Need to feel it deeper in the gut? Think size matters? For those who seek the cleanest, lowest of lows,
where your brain won't hear it all but your bones will sure feel it.. snap up those single Hertz signals by
strappin' this bulldog into an IB and brace yourself for something fierce! :yikes:
