| What are Ohms? |
Ohms are the units that impedance is measured with. Think of impedance as the measure of how hard the amplifier has to push to get current or power to flow. The lower or the smaller the impedance is, the more power the amplifier will produce. Unfortunately, the amplifier circuit wants to push against something, so that if the impedance is too low, lower than 4 ohm the amplifier will in most cases perform very badly and can damage the amplifier badly, and even overheat and stop working. Some DJ Disco or PA power amps can work from a range of 16 ohms down to 2 ohms. If you would like more information on (ohms) please call us so we can help.

| What are Crossovers? |
A passive crossover is term for a mechanism that filters the frequencies fed to the Disco or DJ speakers so that only frequencies that the speaker is designed to produce will be passed through, and the other frequencies are ignored or passed to the other speaker that is designed to take the frequencys.
Most pro audio speaker crossovers are passive, consisting of either a capacitor for cutting out bass and subsonic, or inductors for cutting out higher frequencies.
Crossovers are used in most ready made speaker boxes, you can also get electronic crossovers for bigger more powerful systems, and these crossovers will electronically manipulate the signal before it is put thru the amplifier, you will need more amplifiers to do this and this can be very expensive but will totally change the quality of the sound.

| What are Active Speakers? |
Active PA and Karaoke speakers built in amplifiers. This means that they can be connected directly to a sound source or a mixing console, without the need for an amplifier. The active speaker's input comes in the form of a low-level (line-level) signal passed along an interconnect cable originating at the preamplifier. Passive speakers can be connected to active speakers to avoid the usage and need of an external amplifier. Active PA speakers ease set-up issues for an audio system, at least to some extent. However since a balanced signals (cable) from a signal source and an electrical source (extension cord) must be run to each speaker. This significantly increases requirements for wires being run for each speaker.

| What are Passive Speakers? |
A passive Disco or PA speaker is a speaker that does not have its own power source and draws power from an external amplifier, located outside of the loudspeaker enclosure. Passive speakers are lower in price and lighter than active speakers, and requires significantly less cables to be run to each speaker. Only a single length of cable is required to run from a separate amplifier. These speakers do not have the overhead of requiring multiple electrical outlets for each speaker. An electrical outlet would only be required for the separate amplifier. This can be desirable positioning your speaker with out worry of available electricity.

| What are Bass Speaker? |
Bass Speakers are a loudspeaker design in which the back wave of the speaker cone is routed through a port or vent in the speaker enclosure that reinforces bass output. The port may be located on the front or rear of the enclosure. Using the speaker cone's rear sound wave is an effective way to increase bass response.

| What does RMS Mean? |
RMS (or Continuous Power) refers to the ability of a receiver or amplifier to output its full power continuously. In other words, just because your receiver/amplifier may be listed as being able to output 100W, it doesn't mean it can do so for any significant length of time. Always make sure that when you check for specifications, that the WPC output is measured in RMS terms. This means that the listed power output is a sustained output at a specific volume level.

| What do Monitors Do? |
| Studio monitors are loudspeakers specifically designed for audio production applications such as recording, film, television and radio studios where accurate audio reproduction is crucial. Studio monitors are made in a more physically robust manner than home hi-fi loudspeakers. Whereas home hi-fi loudspeakers only have to reproduce compressed commercial recordings, studio monitors have to cope with the high volumes and sudden sound bursts that may happen in the studio when playing back unmastered mixes. |
