The Pyramid Sequerra Loudspeaker T-1 Ribbon Tweeter - A High Quality Audio Speaker That Reaches 40 KHZ and beyond with negligible distortion and no coloration. The remarkable performance of this tweeter springs from the inherent advantages of the ribbon transducer being put to use in a speaker fully, with no design compromises. Basically the ribbon transducer is simple. A thin ribbon of metal is suspended in a powerful transverse magnetic field. The signal current passes through the aluminum ribbon, forcing it to vibrate through the interaction of the current and the magnetic field. The ribbon is the voice coil and the diaphragm. Its 4.5 lb magnet produces a field of 3100 Gauss across the ribbon and although the ribbon is only 0.7 mil thick and has extremely small mass, roughly equivalent to a wavelength of air at 19 KHZ. The fundamental resonance has been put far below the crossover point, at around 100 Hz. When you add the Pyramid T-1 Tweeter to any high-quality loudspeaker system, you will hear detail you never heard before. With Frequency Responses from 3 KHZ, (the lower limit of the ribbon speaker), to 50KHZ are reproduced with low intermodulation and and frequency modulation distortion. It has peakless, resonance-free response over the entire audio range, so the T-1 adds no color of its own to the sound, but simply extends the high-speed range of the system. Highs disperse perfectly over a full 160 degrees in the horizontal plane, for the firmest stereo imaging possible. The Pyramid Model T-1 was aimed for the absolute best. These units have had one owner, who was a mature and responsible stereo enthusiast and can be expected to provide many more years of beautiful sound enjoyment. Please look at the photos carefully and ask any questions, because everyones hearing sense is different. FULL DISCLOSURE *** These speakers are designed to provide enhanced sound quality in the mid-to-high range sound level. It is not intended to handle bass sounds, so you will need to have separate Woofers as well as a cross- over circuit in order to get the full range tonality.

I am selling a matched pair (2) of the legendary T-9 Ribbon Tweeters Speakers by Dick Sequerra One speaker works great but the other has lower output volume. I opened the foam grills and examined the inside of both. I cant tell anything wrong. The appearance of both speakers look the same to me (see pictures). I also used multimeter to measure the DC resistance across each sides (front and back on each speaker) of the ribbons; and all four got the same readings of about 0.5-0.6 ohm (see pictures). I am not technical person and cant tell the cause. So, my lower than usual price reflects the condition these speakers are in. Please bid accordingly. One grill has a dent which does not appear to do anything bad. The speakers are in good physical condition too. The cabinets are all good, The sale includes just the two ribbon speakers in the pictures; no manual, box, or any other accessories. Please examine the pictures carefully for they are part of description. I pack well and ship worldwide. Quite heavy for the size.

Please examine the pictures carefully for they are part of description. I pack well and ship worldwide. Quite heavy for the size.

The Pyramid Sequerra Loudspeaker T-1 Ribbon Tweeter - A High Quality Audio Speaker That Reaches 40 KHZ and beyond with negligible distortion and no coloration. The remarkable performance of this tweeter springs from the inherent advantages of the ribbon transducer being put to use in a speaker fully, with no design compromises. Basically the ribbon transducer is simple. A thin ribbon of metal is suspended in a powerful transverse magnetic field. The signal current passes through the aluminum ribbon, forcing it to vibrate through the interaction of the current and the magnetic field. The ribbon is the voice coil and the diaphragm. Its 4.5 lb magnet produces a field of 3100 Gauss across the ribbon and although the ribbon is only 0.7 mil thick and has extremely small mass, roughly equivalent to a wavelength of air at 19 KHZ. The fundamental resonance has been put far below the crossover point, at around 100 Hz. When you add the Pyramid T-1 Tweeter to any high-quality loudspeaker system, you will hear detail you never heard before. With Frequency Responses from 3 KHZ, (the lower limit of the ribbon speaker), to 50KHZ are reproduced with low intermodulation and and frequency modulation distortion. It has peakless, resonance-free response over the entire audio range, so the T-1 adds no color of its own to the sound, but simply extends the high-speed range of the system. Highs disperse perfectly over a full 160 degrees in the horizontal plane, for the firmest stereo imaging possible. The Pyramid Model T-1 was aimed for the absolute best. These units have had one owner, who was a mature and responsible stereo enthusiast and can be expected to provide many more years of beautiful sound enjoyment. Please look at the photos carefully and ask any questions, because we provide No surprises satisfaction. FULL DISCLOSURE *** These speakers are designed to provide enhanced sound quality in the mid-to-high range sound, It is not intended to handle bass sounds, so you will need to have Woofers as well in order to get full range tonality.
