Carvin Serial Numbers
THE WHY:
Speakers are rated differently than power amplifiers. This is because the small wire inside the speaker making up the voice coil is only capable of clean non-clipped power levels. This is were the 'under powering a speaker' myth has been so twisted in it's understanding. You can't under power a speaker and damage it, but you can under power a performance or show. If the system is not large enough for the performance and the amplifiers are clipping, it will damage the speaker even though the wattage of the speaker is rated higher than the amplifier. Also, sine wave bench test signals, used to measure the RMS power of an amplifier, are too constant and can heat a speaker voice coil up prematurely not representing a speakers 'real world' rated output.

THE WHAT:
OK, now to the root of continuous, program and peak speaker ratings. A speaker is tested using pink noise limited to (or crossed over at) the lowest frequency the cabinet was designed to work. In many cases this is around 30-40Hz for mains speakers. The continuous rating is the RMS value of the pink noise. The peak rating is 6 DB higher than the continuous rating where most of the peaks generated in the pink noise reach. I say most, because there are some higher peaks. The program rating is an in between value of 3 DB over the continuous rating suggesting a nominal power with heavy music. If the speaker is need for rated power usage, the program rating is a good target to use to determining the needed amplifier power for the speaker. If you are going to use a speaker at its rated program power levels, be sure not to clip the amplifiers - at least not consistently. An occasional clip is hard to prevent, but continuous clipping is a mater of time before the speakers are damaged. In these cases the system needs to be either increased in size by adding more amplifiers and speakers, or limiters should to be used to hold the system to within it's rated capacity.

This file includes Woofer and Mid Range Speakers too.
A diaphragm is the part of a High Frequency Driver that is replaced when it goes bad. It's the part that vibrate and makes the noise inside the driver. The rest of the driver is just a big magnet. Sometimes if you get really bad feedback and your 'HIGHS' go out, usually it's the diaphragm that went bad.

Note how the color is black and brown, when the voice coil gets really hot it starts to burn and it turns black. If you are over driving your speakers that is what happens to the speaker internally. Over time the coating that the voice coil has starts to fall off because it's burnt and the wire becomes exposed, that is when the speaker shorts and fails.

Thiele Small Parameters and Speaker Specifications
We only sell the crossovers, speakers, cables individually.
With an Ohm meter connect the two leads from the meter to the two terminals in the speaker, if it measure 0.00 ohms the speaker is bad. If it measure 4.0 to 8.0 ohms DC it's probably good. If the reading is Open or open load, the speaker is bad too. Look at the speaker and you will find a label indicating the impedance.
Note: In 'AC Resistance' the reading would be more like 3.2 for 4 ohms and 6.2 for the 8 ohm speaker.

If the cone in your speaker is not moving when you press on it, it's because something is wrong with the speaker. The speaker should have deflection when you press on it. When the coil of the speaker is burned it will melt and it will weld the cone that is why it doesn't move up or down. If you plug the speaker into an amp it can damage it. If you overdrive the speaker it will go bad.
The cone is the inside part of a speaker that moves forward and backwards as the speaker is producing sound. For a replacement speaker click here: Carvin Speakers

The amp should be boxed up in its original packaging. If that is not possible, then box it up as best you can. Make sure to leave a protective cushion between the amp and the box. During shipping the amp will be exposed to rough handling. If improperly boxed, the unit will be damaged. Carvin is not responsible for shipping damage due to improper boxing. Remember to fill out your RMA form.

The Thiele specifications are a set of parameters used to describe the audio characteristics of a speaker driver.
No. Carvin Technicians are not permitted to MOD (modify) any amplifier. It is against company policy. Carvin does not repair modified amplifiers. If a modification is found during a repair, then the component values will be returned to factory specs (if it is not rejected).
Moisture is the presence of water in trace amounts. It can cause rot in wood and corrosion in metals, both of which are the main materials in your amplifier and cabinet. When moisture goes inside the amp it can corrode the input and output jacks (causing intermittent crackling, popping, and volume loss), damage the cables inside the amp, and short traces on the circuit boards. If corrosion is present on any of the jacks, the best thing to do is to replace them. For light corrosion, applying contact cleaner to the jacks will help.
Dust and/or sand should never go inside the amp. If any debris goes inside try to clean it out as best you can. Dust and sand can block the fan and vents, causing the amp to overheat, and they can also short components inside. Any debris inside the chassis will also absorb moisture and cause corrosion to form on chassis and circuitry.
Remington also produces a Mountain LSS version that is outfitted with a stainless steel barrel and laminated stock. Laminated stocks and heavy barrel versions like the Model 700 SPS varmint are available for varmint hunting and are extremely accurate. Remington model 700 serial numbers on guns. In 1996 Remington began producing the 700 ML, which stood for muzzle loading rifle for the black powder enthusiasts.
Lightning can cause extreme and intermittent failures to all electrical equipment. Most of these issues are very difficult to repair and usually return after time. In the case of a direct hit, the amp will likely not work well ever again. If there was a black out for a few seconds and the amp does not power back ON, check the fuse. For a replacement fuse click on 'Fuse and Bias Values' in the FAQ Categories menu.

This is a characteristic of something inside the amp being loose. In most cases it is a loose connector, but it can also be dirty or corroded contacts, a bad ribbon cable, or broken solder joints. To check this, take the amp out of the enclosure and verify that all harnesses and connectors are installed correctly. Disconnect and reconnect the ribbon cables. Power on your amp and verify that it is working properly. If the problem persists, you may have to replace a connector and do further troubleshooting. A cable can work its way out from the vibration of a speaker. For a replacement cable click on 'Parts'.
