Effects speaker system

A speaker system comprising

• a speaker enclosure having first and second oppositely facing baffles with each being adapted to have a loudspeaker mounted in an opening thereof,
• first and second dual voice coil speakers for providing mid-frequency and low frequency response being mounted on respective first and second baffles, a first voice coil of each speaker being connected together in an in-phase circuit and the second voice coil of each speaker being connected together in an out-of-phase circuit,
• a low pass filter connected with the in phase circuit to supply low frequency signals to the first voice coils, and
• a bandpass filter connected to the out-of-phase circuit to provide mid-range frequency signals to the second voice coils.

A dipole speaker system having a radiation pattern with a null to allow a listener to be positioned in the vicinity of the null comprising

• a speaker enclosure having first and second oppositely facing baffles with each being adapted to have loudspeakers mounted in openings thereof,
• first and second dual voice coil speakers for providing mid-frequency and low frequency response being mounted on respective first and second baffles, a first voice coil of each speaker being connected together in an in-phase circuit and the second voice coil of each speaker being connected together in an out-of-phase circuit,
• a low pass filter connected with the in phase circuit to supply low frequency signals to the first voice coils,
• a bandpass filter connected to the out-of-phase circuit to provide mid-range frequency signals to the second voice coils,
• a pair of high frequency speakers respectively mounted to the first and second baffles and having voice coils connected together out-of-phase, and
• a high pass filter connected to the voice coils of the high frequency speakers.

A dipole speaker system having a radiation pattern with a null to allow a listener to be positioned in the vicinity of the null comprising

• a speaker enclosure having first and second oppositely facing baffles with each being adapted to have loudspeakers mounted in openings thereof,
• first and second dual voice coil speakers for providing mid-frequency and low frequency response being mounted on respective first and second baffles, each of said dual voice coil speakers having first and second voice coils,
• first and second high frequency speakers respectively mounted to the first and second baffles, and each having a voice coil,
• the first and second coils of the first dual voice coil speaker, the first coil of the second dual voice coil speaker, and the coil of the first high frequency speaker all being in-phase with each other and out-of-phase with the second coil of the second dual voice coil speaker and coil of the second high frequency speaker, the second coil of the second dual voice coil speaker and coil of the second high frequency speaker being in-phase with each other,
• a low pass filter connected to supply low frequency signals to the first voice coils of the first and second dual voice coil speakers,
• a bandpass filter connected to provide mid-range frequency signals to the second voice coils of the first and second dual voice coil speakers, and
• a high pass filter connected to the voice coils of the high frequency speakers.
