I set the crossover at 80hz but, like I said, I really don't understand this stuff. A 3-way crossover of this complexity is not cheap. Here are some things to look for in speaker testing: A large drop (~20dB) at a crossover point would indicate that the drivers are canceling each other out.
The phase crossover frequency is the frequency at which the phase angle first reaches −180° and thus is the point where the Nyquist plot crosses the real axis (Figure 12.12).On a Nyquist plot the (−1, j0) point is the point separating stability from instability. Unfortunately, the tweeter used in this design did not measure close to the data sheet at all and required pushing the crossover frequency up. • Since L-pads are made from resistors, they don't induce any phase shifts, or affect frequency response. • An L-pad circuit attenuates a speaker. Setting the cutoff frequency and slope of both filters will determine the crossover point. The recommended frequency range for a speaker can vary, always consult with the manufacturer before setting your own crossover points. In a passive speaker, the electronic crossover components determine where the sound transitions from the speaker channels to a subwoofer. Crossover points and Order. In your Pioneer receiver, the crossover setting determines the point around which the receiver starts diverting audio signals from your speakers to your subwoofer. At the crossover point sound comes from 2 sources and on-axis directivity is increased. The sub starts at 28hz.
At the crossover point, power to each speaker is reduced -3dB (1/2) so total sound energy is 1. Given this is an off-the-shelf speaker that is to be expected. For an individual speaker, such as your CR67, the internal crossover determines the range of frequencies that the tweeter plays and the range of frequencies that the woofer plays. The crossover point is the point where the two filters intersect. I don't see anything in any of these tests that would warrant any additional modifications to the crossover. Crossover Frequency.
The crossover frequency is the frequency at which sound transitions from one speaker to another.
3-Way Crossover Bill of Materials. Also, can anyone tell me the relationship between the crossover frequency and the AV receiver speaker settings (i.e., large/small)? < … Using cheap electrolytic capacitors this crossover costs close to $150 for components alone. The speaker system employs a stiff cone driver which has no crossover circuit (namely a LPF) to limit its bandwidth to reduce its audible break up modes at higher frequencies. • L-pads keep the load "seen" by the amplifier constant, affecting only the power delivered to the speaker. Audio crossovers are a type of electronic filter circuitry used in a range of audio applications, to split up an audio signal into two or more frequency ranges, so that the signals can be sent to drivers that are designed for different frequency ranges. The power delivered by the amplifier remains constant.
