This unique stereo development means that you can use your Grenadiers anywhere. They need not be placed in corners or against walls. You do not have to sit where 'X' marks the stereo spot. You can sit where you like, move as you wish and never lose the concert hall effect created by the one speaker system designed for complete stereophonic flexibility and fidelity.

• A. EXCLUSIVE SONIC COLUMN a totally damped-rigidly stiff speaker enclosure. There are no cabinet vibrations. The hand rubbed, hardwood cabinet is braced against all modes of vibration.
• B. THE WOOFER FACES DOWNWARD close to the reflecting floor surface. It feeds through a front loaded horn with a full circle aperture throat. This provides 360 degrees radiation for full dispersion of sound and prevents standing waves from developing in the room.
• C. THE WORLD'S LARGEST WOOFER ceramic magnet structure (18 lbs.) combines with massive mid range and tweeter drivers to produce over ONE MILLION LINES OF FORCE (enough to lift a compact car). The Empire Royal Grenadiers are probably the most powerful home speakers in use today.They can each handle well over 125 watts of pdwer per channel without burnout or overload. More than enough power to fill a large auditorium. No orchestral crescendo will ever distort or muddy.
• D. ALUMINUM VOICE COIL for low mass in this ultrasonic domed tweeter extends frequency response beyond audibility. A compression type mid range direct radiator creates spectacular presence and realism. Empire's patented diffraction ring type wide angle acoustic lens provides 160 degree dispersion, more than twice that of ordinary speakers.
• E. COMPLETE SYMMETRY OF DESIGN with terminals concealed underneath. Speaker placement is not critical. Move it, turn it, aim it or bounce it. You get full sound, full separation, full stereo anywhere in your room.
• F. FREQUENCY RESPONSE a unique combination of electrical and acoustic crossovers and cutoffs avoid woofer cone breakup and mid-range response dips. The woofer, mid-range and tweeter combine at mathematically correct crossover frequencies.

You will notice no change in sound level of bass, mid range and highs. Full frequency and separation is assured by Empire's exclusive divergent acoustic lens system.

Try this test with any other brand of speaker. Some speakers will only have a narrow angle of high frequency sound propagation. Some speakers may have 2 or even 3 bands of high frequency sound. With these other speakers, slight shifts of position, turning one's head, or even leaning to one side may cause sharp changes in the listening tone and level.

PREMIER SPEAKER SYSTEM FOR THE DISCERNING MUSIC-LOVER

In the Royal Grenadier, Empire's total stereo design is coupled with the ultimate in electronic engineering for truly matchless sound reproduction. Facing downward within the.stereo cylinder is a 15-inch high-compliance woofer built around an 18-pound ceramic magnet structure. Unparalleled in power and precise response, this magnet controls a 4-inch voice coil that remains within the magnetic gap during even the widest-excursion bass notes.

Non-linear motion is eliminated, and with it the low bass distortion that less powerful drivers create. At 450 cycles, this woofer is cut out of the system electrically, by the crossover network, and also acoustically by its impedance-matched horn. Speaker-cone break-up, a prime cause of distortion in woofers allowed to reproduce higher frequencies, is totally blocked by this extraordinary double cut-off.

The powerful mid-range direct radiator that reproduces the 'heart' of the musical spectrum utilizes the same engineering combination of magnetic power, precise voice-coil control and perfect compliance for unsurpassed linear response and clean, clear, distortion-free sound. At 5,000 cycles, the same double cut-off takes place via the cross-over network and the acoustic impedance of the Grenadier's divergent lens.

And, like the other components of this premier speaker system, Empire's ultrasonic domed tweeter is precision-engineered to give you nothing but pure, undistorted, perfectly-balanced music. The Royal Grenadier has a power-handling capacity of 125 watts per channel - the ultimate protection against distortion, burn-out and uneven response, yet its efficiency is so great that a mere 20 watts of power is sufficient to drive it to ear shattering levels..

FOR SUPERB STEREO SOUND WITH TODAY'S INTEGRATED RECEIVERS

With a power-handling capacity of 90 watts per channel, these new Grenadiers are the perfect companions to the best and most powertul of the new solid-state integrated stereo receivers. Both provide all the advantages of Grenadier total-stereo design - non-resonating cylindrical housing, downward-facing 360° dispersal woofers, and electric-acoustic double response cut-offs. Acoustic lenses achieve 160° high-frequency dispersion and these units' smaller overall size makes them more adaptable to the space limitations of modern apartments.
