NEW SPEAKER SYSTEM ENABLES EVEN MORE POWERFUL STEREO SOUND FOR MOTORCYCLES
	Trabuco Canyon, CALIF. Sept 1, 2001 -- MH Instruments (MHI) has taken their market proven Rumble Road^TM Speaker System and incorporated higher gain amplifiers along with PCxi402 Speakers from Blaupunkt to create the ultimate sound for cruisers - even at highway speeds - in this standard size package.
	The PCxi402 speakers feature an Extended Pole Design and Graphite Injected Plastic cone material offering lighter mass compared to older paper cones but without the flexing properties common to paper. This gives a much "tighter" base response and smoother high frequency response without distortions often found at high listening levels.
	The Extended Pole Design increases the length of the pole piece of the speaker by only a few millimeters but the performance results are significant. The non-linear fields around the voice coil's gap are greatly reduced thus improved heat dissipation (higher power handling) and increased cone movement control (higher power but with "cleaner" response). This makes the Rumble Road Premium^TM Speaker System one of the best sounding and loudest integrated amplifier units on the market!
	"We've road tested many speakers and personal Walkman devices and have found that the current combination of higher gain amplifiers and Blaupunkt speakers in the Rumble Road Premium^TM offer the best sound quality for the money." says MHI Principal Haig Balian. "Rumble Road Premium^TM speakers provide the ultimate in motorcycle integrated sound systems."
