Hi rocroc, first, check to see that all the screws are tight that hold the speaker drivers, and panels in place are tight. Loose screws can make a monitor rattle. Access to the internals in powered monitors is often by a rear connection plate, or through the from by removing the woofer. A cosmetic band is often used around the woofer to hide the screws. you will need to carefully remove this before you can get to them. If all the screws are tight, then you may have a problem with the driver itself. best way to check is by doing an audio sweep from 20hz to 5khz with it sitting on the benchout of the box. If it has any weird noises, the voice coil assembly may be loose or damaged. If the "pumping" problem happens with no signal, then you may have a problem with the internal circuitry. Check for loose bits first, and get back to me here, happy to talk more about it.

Graeme

Sounds to me like the voice coil is damaged. But without hearing it I wouldnt be able to tell you. If the voice coil is damaged there is no way to fix it.

M audio studiophile BX8a deluxe has very hot back panel when on after a few minutes


There is a problem with the amplifier internal to the unit, most likely from the main power transformer. Return to the place of purchase, or a service center for repair/replacement.

I have recently purchased a set of M-Audio Studiophile BX8a Deluxe studio monitors. I can't register them for warranty because I can't find any serial number on the monitors or box that they came...


Call M-Audio and ask them about it... It is POSSIBLE that your speakers are counterfeit. It has been happening with high value audio equipment. There has been some failures of this product as well. Also contact the company you bought them from. There is a lot of grey market stuff on Ebay... I hope that wasn't your source.

I HAVE THE M-AUDIO SP 5B MONITORS AND ONE OF THEM WON'T THROW OUT ENOUGH POWER TO PUSH THE SPEAKER WITHOUT MAKING A BUZZING DISTORTED SOUND. IT'S NOT THE SPEAKERS BECAUSE I TESTED IT ON THE OTHER SPEAKERS...


It sounds like the speaker might be "blown". If you take the cover off... looking at the speaker, does the speaker's cone have a crack? Or is it separated around the edge... if so, it is blown. Most of the time this can be fixed... but you will have to take it someplace.

Is there a company in your area that professionally installs car audio systems? If so, they usually can repair speakers, or they will know who can.

I have a pair of m-audio bx8a deluxe monitor speakers. I need to know how hook my iPhone up to them or just one of them. I tried using a adaptor and plugging into the trs input but the music is distorted....


The conection you made is not quite right. This is because the TRS (and the XLR) connectors at the back of the BX8a are for balanced signal. You have to use either this cable or connect both middle and ground point of the TRS connector at the ground. In other words the ground from the ipod must be connected with ground AND middle ring of both BX8a and the ring of the ipod must be connected with on BX8a TPS tip and the tip of the ipod must be connected with the other BX8a tip. I don't know if you are familiar with soldering connectors, in this case post me back to make a schematic for you with the connections.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

M-audio Bx8a's one monitor very low volume compared to other.


NO, I HAVE HAD TWO PAIRS OF THESE SPEAKERS. tHE SECOND PAIR I HAD FOR TWO WEEKS AND SAME PROBLEM, EITHER LEFT OR RIGHT SIDE GOES OUT.

I Insert a compressor on the stereo buss to protect the speakers from transients and they just loose the woofer everytime.

They cannot be trusted, DONT WAISTE YOUR MONEY.

Woofer not working on new bx8a speaker


Hi ermo

Your new speakers are BiAmped, and if a woofer is not working then it is probably a fault in the amp or connection for that woofer, or the the woofer itself has a problem. If they are brand new, I suggest you take it back to purchase point to get sorted out. There is nothing that you can do that will NOT void your warranty. If you do not have a warranty, then get back to me here and we can work through the problem. Cheers

Connect BX8A speaker to PC


Hello waddragon,

First, let's start with the BX8a. Those are powered speakers (built-in amplifier in each) so, you do not need a pre-amp. What you need to connect them to your computer is a 3.5mm to XLR cable OR a 3.5mm to 1/4" TRS cable, also known as 3.5mm to two 1/4" mono plugs (the back of the BX8a has inputs that accept either type). Cables are available at most any electronics stores. Make sure you buy a long enough cable to run from the back of the computer to where the speakers will be.
It sounds that you only have one BX8a which means you'll be listening to only one channel of the stereo output. In any case, make sure before connecting the speaker(s) to the computer that speaker power is off and volume control is at minimum. Connect the 3.5mm cable end to Line Out 1 jack of the X-Fi sound card and either the XLT or TRS ends to the speaker(s) input(s). Play some audio content on your computer, turn on speaker(s) and slowly increase volume to a safe level. Everything should work fine.
Let me know how it goes.
