An N-way loudspeaker usually has an N-way crossover to divide the signal among the drivers. A 2-way crossover consists of a low-pass and a high-pass filter. A 3-way crossover is constructed as a combination of low-pass, band-pass and high-pass filters (LPF, BPF and HPF respectively). The BPF section is in turn a combination of HPF and LPF ...
In 1975 Ed Long [1] in cooperation with Ronald J. Wickersham invented the first technique to Time-Align a loudspeaker systems. In 1976 Long presented "A Time-Align Technique for Loudspeakers System Design" [2] at the 54th AES convention demonstrating the use of the Time-Align generator to design improved crossover networks for multi-way loudspeakers systems.
This is the biggest advantage of L-R crossovers compared to even-order Butterworth crossovers, whose summed output has a +3 dB peak around the crossover frequency. Since cascading two n th -order Butterworth filters will give a (2 n ) th -order Linkwitz–Riley filter, theoretically any (2 n ) th -order Linkwitz–Riley crossover can be designed.
The expression / can be replaced by the value 9.523×10 −7 s 3 /m 3 for dry air at 25 °C. For 25 °C air with 50% relative humidity the expression evaluates to 9.438×10 −7 s 3 /m 3 . From the efficiency, we may calculate sensitivity, which is the sound pressure level a speaker produces for a given input:
John Boyd says that being a part of this Tuesday night’s 3-way crossover between CBS’ three FBI shows was no less than “an out-of-body experience.” Three years ago, Boyd’s FBI character ...
Bi-amping typically consists of a crossover network and two or more drivers. With ordinary loudspeakers, a single amplifier can power the woofer, mid-range and tweeter through an audio crossover , which filters the signal into high- medium- and low-frequencies (or high- and low-frequencies in 2-way speakers) – a mechanism that protects each ...
The best way to store vitamins for optimal shelf-life. Elements like heat, humidity, light, and air are the “main enemies of vitamin freshness,” says Blatner. “Keep them cool, dry, and out ...
Last TV season gave us the first-ever three-way crossover involving a trio of NCIS series: the original, D.C.-set mothership, NCIS: Los Angeles, and relative newcomer NCIS: Hawai’i. NCIS: LA has ...
