Car Audio Speakers in Cabinet

Pages: (1/3) > >>

DeLuSioNal29:

I had wanted to install two 5¼" car audio speakers (4 ohm) into my cab, right below my marquee.  They would be powered by 4 ohm computer speakers which would be spliced into the new speakers.  Kevin Steele from Retroblast.com did something similar:  http://www.retroblast.com/Videos/Wiring-Up-An-Arcade-Cabinet-Sound-System.php

Here's my main concern.  Will the unshielded speakers destroy my monitor?  Will I see color bleeding because of the magnets?

Here are the speakers that I want to order: (must have blue color to match my blue theme)

Do they even make shielded speakers in blue?

Thanks in advance!

It probably won't be a problem. I've never seen original arcade machine speakers that were shielded.

I think the biggest issue that you may run into is destroying the speakers by underpowering them.  If you use an underpowered amp (which you may well be doing with using computer speaker amps), you'll probably have to crank up the amps to get some decent volume out of them.  Now, when you crank up the amp too much, the amp won't be able to put out the power, which introduces a whole lot of distortion into the signal.  Think of a sine wave, then lop off the tops and bottoms of the waveform.  (This is known as clipping)  This is what you're sending into the speaker.  Notice how at the peaks, the direction of wave abruptly changes?  Speakers don't like that.

I had discolouration on my monitor from my car speakers in my cab. I tried a few different things to resolve it like bucking magnets but i still get some distortion. I do have a deguass wand which will fix the problem for a while. It seems to be at it's worse when the volume is loud for a period of time. So I would be careful about how close you place your speakers to your monitor. Another alternative is magnetic shielding material but its very expensive I hear.

I have 5 1/4s in my UAII cabinet,
with a wells gardner 27" and so far have not seen any distortion or bleeding
