Question about M-Audio Studiophile BX8a Speaker

Open Question

M-audio bx8a not loud enough?

Here is the problem. Month ago one speaker started to have a distortion in sound , it was random. So i took it for repairs. Finaly ive got the speaker back, but with some problems. The speaker is filled with somekind of stuffing????

Well both speakers sounded practicaly the same in terms of loudnes at the same calibration setting. After the repairs..the "healty" speaker is twice louder at the same calibration setting than "repaired" one...

And another thing that i almost forgot...When the calibration buttons are on the same setting ( lets say 12 o clock ) the noise from the speakers is practicaly the same ( loudness ), so shouldnt be the music the same?

tnx for help!

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.

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

SOURCE: 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

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.

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.

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.

Hi David

The fault may be the bass driver itself or the Low Frequency power amp built into the speaker box. hard to determine which it is because it is intermittent. There are a couple of things to try. when the fault occurs.
  1. just lightly touch the cone on the bass driver see what happens. If it fires up again, it has failed soldering on the spider wire connections from the terminals to the cone. This can be repaired by a decent sound guy the does speakers, or a specialist near you that can be found easily enough. A new replacement driver is also an immediate option if you don't mind spending the bucks.
  2. if the above didn't work, to prove to yourself where the problem may lay, you could swap the bass drivers from one box to the other and see if the fault follows the driver, or remains with the speaker box. If the electronics are faulty, unless you have some decent experience with soldering and fault finding, you may be best to get it to a repair guy,
If you cant get it sorted, please provide me with your location(not address:)) and I will be able to locate a decent guy that knows what he is doing for you. Cheers

Humming BX8


Hello docjgg,

This sounds like it may be a loose connection (ground) generation common mode noise or it may be a capacitor in the power supply going bad and not providing enough filtering of the AC voltage (allowing for 60 cycle hum). You should get a schematic for the speaker or just take some rule of thumb measurements of the power supply output, with an oscilloscope (you will be looking for ripple voltage, what you could do is use one of your good speakers as a comparison of good to bad.

If you do not want to work on this yourself, you could take the speaker to any TV repair shop or audio repair shop.

I hope this helps

Thank you,

Hook up pair Bx8a to pc


XLR? not true. gold plated, balanced trs cables have a better sound and actually compliments the bx8's technology. that said, you can get cable that is trs-balanced on one end and rca's on the other. then just get a "Y" right-left rca into a stereo 1.5 cable. easy and cheap. but using xlr's for output? NO. save those for your input MIDI instruments and controllers.
