Bose Model 501 speakers

The Bose Model 501 Direct/Reflecting speaker system incorporates a ten-inch woofer and two three-inch tweeters along with a unique Direct Energy Control allowing the speaker system to easily adapt to your listening room.

Utilizing the walls, ceiling, and floor of your listening room to reflect sound, the Model 501 creates a sense of spaciousness with a strong center image. By radiating the high-frequency sound through the side and front grille panels, the 501 simulates the proportion of reflected and direct sound experienced in the larger environment of a live performance.

The ten-inch woofer found in the Model 501 provides outstanding bass performance while providing a portion of the direct sound at middle range frequencies. The extra-long excursion suspension yields powerful low distortion bass reproduction.

The Model 501 Direct Energy Control adjust the percentage of Direct Sound radiated into the listening area. This control primarily affects the spatial distribution of high-frequency energy and can be used to compensate for speaker placement and listener taste.

 

 

Specifications

Spatial Characteristics :  the Model 501 utilizes Asymmetrical Design for optimum stereo reproduction with rear and side wall reflections. The tweeters, angled toward the rear walls, reflect sound energy into the main listening area. A Direct Energy Control provided with the outward-directed tweeter allows control of the spatial characteristics of the speaker system. The Model 501 is designed in mirror-image pairs for optimum stereo reproduction.

Speaker Configuration :

Woofer - One ten-inch acoustic suspension woofer utilizing a long-throw 1,5-inch diameter voice coil with 16-ounce magnet. Linear high-excursion suspension system provides high output capability.

Tweeter - Two three-inch, wide-range tweeters with extended low-frequency response for use with Direct Energy Control Flat Total Power Radiation to over 16 kHz

Enclosure -  A walnut grain vinyl clad, floor-standing loudspeaker with acoustic suspension design and acoustically transparent side panels.

Impedance :  The impedance of the Model 501 speaker system is conservatively rated at 4 Ω , hower, since the impedance of the Model 501 is substantially above 4 Ω  over all but a small portion of the frequency range high quality receivers can operate an additional pair of 8 Ω  speakers or a second pair of 501's (connected in parallel) with no difficulty.

Power handling:  The minimum recommended power - 20 watts rms per channel. Amplifiers rated over 50 watts can be used with the Model 501, however, each channel should be fused.
