When loudspeakers are connected in _____, current from the amplifier passes serially through the loads, and the net impedance is the algebraic sum of the individual impedances.
What is Series Wiring?
100
This rating comes from a low level tone played through a speaker for a long time to determine heat resistance.
What is Continuous?
100
this is phase cancellation due do a speaker not in an enclosure.
What is rarefaction?
200
A steel rod that goes inside the voice coil and magnet
What is Pole Piece?
200
The opposition to current in an AC circuit
What is Impedance?
200
When connecting, Impedance is halved by doubling the # of speakers of like Impedance.
What is Parallel Wiring?
200
This Rating comes from a very loud tone played for less than 1/10 sec. to test durability.
What is Peak Rating?
200
you can extend the low end response of a speaker if you use this.
What is a port?
300
Cap over the Gap to keep out dust and debris that can cause distortion
What is the Dome?
300
The Impedance of an Amplifier ( Constant )
What is Source Impedance?
300
These crossovers work at a "high" level.
What is Passive?
300
this rating is used to determine proper amplification.
What is Program?
300
this type of speaker wiring produces less impedance.
What is Parallel?
400
Provides suspension for the voice coil allowing it to move freely, Attaches voice coil to cone
What is the Spider?
400
The Impedance of a Speaker (Variable )
What is Load Impedance?
400
2 8-Ohm speakers in Parallel have this resistance.
What is 4 Ohms?
400
2 useful applications for this include Talkback and Time-Based processing.
What is an Aux?
400
Switching your Amplifier to this mode flips the phase of one of the outputs.
What is Bridge Mono?
500
A coiled wire wrapped around the former that creates a secondary magnetic field when amplified
What is Voice Coil?
500
The lowest amount of impedance the speaker will present to the Amplifier
What is Nominal Impedance?
500
3 16-Ohm speakers in series have this resistance.
What is 48 Ohms?
500
the loss of no more than 1db of signal due to the heat of fundamental electronic components in a Passive crossover.
What is Insertion Loss?
500
this is the rate at which the frequencies gradually roll-off after the cut-off point.
