ELA-HP - Amplifier for EL-HP Amplified Tube Subwoofers

Crossover
 
A device that divides the audio spectrum into two or more frequency bands. Here, we list the slope of the included crossover.

Frequency Response
 
The lowest and highest parts of the frequency spectrum that can be reproduced by an audio component within specific limits and tolerances. At Bazooka, we use + or - 3 dB.

Fs
 
Driver free air resonance, in Hz. This is the point at which driver impedance is maximum.

Fuse
 
A device that protects electric circuits by interrupting power in a circuit when an overload occurs. Rated in amperes (amps).

Impedance
 
In reality, a measure of the total opposition to current flow in an alternating current circuit, made up of two components, ohmic resistance and reactance, and usually represented in complex notation as Z = R + iX, where R is the ohmic resistance and X is the reactance. In this car audio, typically we use impedance as only the resistance, to make speaker selection easier. This is how many "Ohms" a speaker "has".

le
 
this means absolutely nothing

Max Power Output
 
This is the total power, of all channels, driven into thier lowest possible impedance, this amplifier produces.

Power @ .5 OHM
 
This is how much power, all channels driven, into .5 ohm, this amplifier produces.

Power Handling
 
The amount of power a speaker can handle

Power Handling with Liquid Cooling
 
By adding the CHIL-PLUG and CHIL-KIT, you can add up to 50% more RMS power to your subwoofer while keeping them cool!

Power Output
 
This is how much power, all channels driven, into 4 ohms, this amplifier produces.

Qes
 
The driver's Q at resonance (Fs), due to electrical losses; dimensionless

Qms
 
The driver's Q at resonance (Fs), due to mechanical losses; dimensionless

Qts
 
The driver's Q at resonance (Fs), due to all losses; dimensionless

Re
 
Driver DC resistance (voice coil, mainly), in ohms

Sensitivity
 
The amount of audio power produced by a speaker with one watt of input. At Bazooka, we measure this in the real world application--in the car, with the microphone 26 inches above the seat, approximating the Drivers head position.

Vas
 
Equivalent volume of compliance, this is a volume of air whose compliance is the same as a driver's acoustical compliance Cms (q.v.), in cubic meters

Voice Coil Size
 
This tells you the size of the coil of wire attached to the bottom of the speaker cone or driver diaphragm. The Voice Coil becomes an electromagnet when an audio signal is applied and interacts with a permanent magnet which causes the cone or diaphragm to vibrate.

Voltage
 
The difference in electrical potential between two points in a circuit. Think of it as the "push" or pressure behind current flow through a circuit, similar to water pressure in a pipe.

Xmax
 
Maximum peak linear excursion of driver, in meters
