These vintage cone tweeters exhibited very flat frequency response, low distortion, fast transient response, a low resonance frequency and a gentle low-end roll-off, easing crossover design. Typical of the 1960s/1970s-era was the CTS "phenolic ring" cone tweeters, exhibiting flat response from 2,000 to 15,000 Hz, low distortion and fast ...
Prior to the soft dome tweeter, the belief was that only a rigid tweeter was capable of producing high frequencies. The soft dome revolutionized the reproduction of high frequency sound; it produced a smoother frequency response, wider dispersion to higher frequencies, and had almost no high frequency resonances, all with much lower distortion ...
A typical characteristic of a 2-way speaker is that at the crossover frequency, due to the physical distance between the centres of the woofer and tweeter, the sound that emanates from the combination is not omni-directional, but lobed. Within the region of the lobe the sound level, at the crossover frequency is much higher as compared to ...
The midwoofer-tweeter-midwoofer loudspeaker configuration (called MTM, for short) was a design arrangement from the late 1960s that suffered from serious lobing issues that prevented its popularity until it was perfected by Joseph D'Appolito as a way of correcting the inherent lobe tilting of a typical mid-tweeter (MT) configuration, at the crossover frequency, unless time-aligned.

Exploded view of a dome tweeter. A tweeter is a high-frequency driver that reproduces the highest frequencies in a speaker system. A major problem in tweeter design is achieving wide angular sound coverage (off-axis response), since high-frequency sound tends to leave the speaker in narrow beams.
Some changes early in driver life are complementary (such as a reduction in accompanied by a rise in ) and result in minimal net changes (small fractions of a dB) in frequency response. If the performance of speaker system is critical, as with high order (complex) or heavily equalized systems, it is sensible to measure T/S parameters after a ...
The mid-range, tweeter and super tweeter have crossover controls for switching between a laboratory "flat" +/- 0db neutral response and a "room EQ" response. Tested frequency response is measured in an anechoic chamber from 20 Hz to 20 kHz, and displayed in a graph shown in original Marantz brochure.
A super tweeter is generally designed to respond well into ultrasonic frequencies over 20 kHz, the commonly accepted upper frequency limit of human hearing. Super tweeters have been designed for psychoacoustic testing, for extended-range digital audio such as Super Audio CD intended for audiophiles , for biologists performing research on animal ...
