DESCRIPTION

The FORCE 10-, 12-, and 15-inch

loudspeakers are designed for professional high level, high quality musical instrument and sound reinforcement systems. Power capabilities are 150 watts per EIA Standard RS-426A. The construction of FORCE loudspeakers features a low mass voice coil on a rugged laminated Polyimide coil form, driven by a 10-lb magnetic structure. Also featured are a heavy-duty curvilinear cone and a fatigue resistant cone suspension. Both the coil and magnetic structure are vented. All of this IS packaged in a husky eight-spoke diecast aluminum frame with a heat radiating finned back cover. FORCE speakers may be front or rear mounted without an adapter.

POWER HANDLING TEST

The FORCE 10, 12, and 15 are designed to withstand the power test described In EIA Standard RS-426A. The EIA test spectrum is applied for eight hours. To obtain the spectrum, the output of a white noise generator is fed to a shaping filter with 6-dB-peroctave slopes below 40 Hz and above 318 Hz. When measured with the usual constant percentage bandwidth analyzer (one-third octave), this shaping filter produces a spectrum whose 3-dB-down points are at 100 Hz and 1200 Hz with a 3-dB-per-octave slope above 1200 Hz. This shaped signal is sent to the power amplifier with the continuous power set at 150 watts into the 5.6 ohms EIA equivalent impedance (29 volts true RMS). Amplifier clipping sets instantaneous peaks at 6 dB above the continuous power, or 600 watts peak (58 volts peak). This procedure provides a rigorous test of both thermal and mechanical failure modes.

“We carefully inspect every speaker when we buy it and bring it up to our standards before we offer it for sale.”

*Please note: we do our best giving descriptions of used pieces. We have found it impossible to describe every mark on an instrument or amp that is not in the "mint" category. Also, what's important to you may not be important to someone else. For example, you may say, "I don't care what it looks like as long as it plays or sounds well." Another person may say, "Body cosmetics are very important to me so tell me about every scratch, nick and blemish." So, please ask the questions that are most important to you. If you ask they will be answered. They are free and there's no limit. Additional photos can also be made available.

This is a specific item that is also being offered for sale in our brick & mortar location. It is possible that it has just been sold. Please ask if it is still available before purchasing.

*It is our policy to require a signature on delivery of all musical instruments. Please let us know if you prefer no signature required when ordering or we will automatically require a signature.

If you prefer your item to be sent without a required signature Imperial Guitar and the selected carrier can no longer be responsible for the security of the package once it has been delivered.
