For that reason, the Atlantic Technology System 250.1 was designed with acoustically matching drivers. To help achieve this goal when using front speakers from another manufacturer, we have provided two controls (Figure 4) on the rear of the 253.1 C enabling you to adjust its tonal characteristics to emulate those of your front left and right speakers. Begin the adjustment procedure by turning both control knobs to the “251.1” position. This approximates the Atlantic Technology 251.1 LR speakers. Next, use your surround sound receiver/decoder’s “test” mode to generate “hiss” from each speaker and adjust the 253.1’s controls for the closest match. Although an absolute match is not usually possible, fine tuning the controls while watching high quality movies will generally yield excellent results. If most of your listening is Dolby Stereo movies, you may wish to adjust both controls down slightly to compensate for the natural brightness of many movie soundtracks. Note: Some surround sound decoders and receivers offer a choice of “normal” or “wide band” modes for the center channel. The Model 253.1 C was designed to be used in the “normal” mode. aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa0 5 Models 251.1 LR, 253.1 C, and 254.1 SR tlantic ATECHNOLOGY Mounting The 251.1 LR and the 254.1 SR speakers can be mounted in a variety of ways: On speaker stands. Atlantic Technology 156 ST speaker stands provide an ideal height (29" above the floor) and fit for most rooms. They are available in black or white. On the wall. To mount your speakers on a wall, we have provided metal key-hole brackets. Simply place the bracket over the oval recess on the rear of the speaker and fasten it using the enclosed #6 x 1" screws. Pilot holes are provided. For greatest flexibility, use pivoting ball-and-socket wall brackets of suitable weight rating (e.g., Omnimount 50 Series, Vogel, etc.) usually available from your local audio/ video retailer. For safety, please use suitably secured wall anchors (such as molly-bolts), or screws driven into wall studs. On a bookshelf. Adhesive rubber feet are included. In the wall. The Atlantic Technology 254 INRF in-wall kit includes all the necessary hardware and trim. (254.1 SR only) Listening Levels and Power Handling–IMPORTANT! The power recommendation for these speaker components assumes that you will not operate your amplifier/receiver in a way that produces distortion. Even rugged speakers like System 250.1 can be damaged by a moderately powered system driven beyond its intended capacity. The harsh amplifier clipping that occurs in this situation will cause damage to the speaker system that is not covered by the warranty. The System 250.1 will play very loudly when provided with enough power to do so. Again, consult your dealer or Atlantic Technology for additional information. Care of your Speakers Clean your speaker cabinets using a soft cloth moistened with a mild, non-abrasive glass cleaner being careful not to wet the individual drivers or the edges of the cabinet. After carefully removing the grilles from the speakers, clean them with a quick pass from a vacuum cleaner with a brush attachment. This should remove any dust accumulation. Avoid placing your speakers in direct sunlight that may, over time, fade the finish. aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa0 6 Models 251.1 LR, 253.1 C, and 254.1 SR tlantic ATECHNOLOGY System 250.1 Specifications Description 251.1 LR 253.1 C 254.1 SR Type Sealed-box, 2-way Sealed-box, 2-way, Sealed-box, spatially-enhanced Adjustable Timbre surround speaker Drivers (2) 4" polypropylene (2) 4" polypropylene (2) 0.5" polypropylene (1) 0.75" dome tweeter (1) 0.75" dome tweeter (2) 4" polypropylene Frequency 50Hz – 20kHz 80Hz – 20kHz 80Hz – 20kHz Response (± 3dB) Nominal 8W 8W 8W Impedance Sensitivity 90dB 90dB 90dB Recommended 10 – 150W 10 – 150W 10 – 150W Amplifier Power Size (W x H x D) 6.0 x 13.0 x 8.5in 15.0 x 6.75 x 7.75in (including base) 9.5 x 10.5 x 6.4in 152 x 330 x 216mm 380 x 152–170 x 197mm 241 x 267 x 163mm Weight (each) 12lbs 10.25lbs 8.1lbs 5.45kg 4.65kg 3.63kg Specifications are those in effect...
