PA Speakers as Speaker Setup for my rig

Hey guys!

I've recently asked about a question in another topic, and I now wonder about something else...
I have purchased PA speakers for my studio and set up my computer close to them.

My speakers are these :

Spoiler

Compact, lightweight 2-way active loudspeaker system
12-inch extended range low frequency driver
1.34-inch (34mm) compression driver with 1-inch exit
400 watts of output power
XLR mic input
1/4-inch line input
Volume control
2-band equalizer (Bass and Treble Controls)
Line output allows daisy chaining of additional speakers
Built-in Optimax compressor/limiter with two-stage speaker protection
1-3/8-inch pole mount receptacle
Two oversized ergonomic carry handles
Dual-angle floor monitor positioning options
Solid polypropylene construction



I wanted to know if my computer tower is really really close to one of the speaker cabinets, will a magnetic field interfere with either and cause damage to data on the computer, or damage to the speaker? I didn't turn them on yet, but they are close to my tower, on the floor, just besides it and I wanted to be sure before doing anything...

Also, I wanted to know if it was possible to make these PA speakers my computer speakers...
I have this sound card : HT Omega Claro +

I would *HIGHLY* suggest not placing large MAGNETS next to a computer / MAGNETIC STORAGE device (Hard Drive) unless you don't want to save any data ;)

And yes, you can play your computer speakers through the sounds system.


Take a mini audio cable (1/8") to RCA splitter, and plug it into the line level RCA input at the top right of your mixer.

And are my speakers "Large Magnets" ? Because I can't really position them anywhere else then besides my tower, don't have any other space...

Every speaker is driven by a magnet, the larger the speaker, the larger the magnet.

A speaker works by adjusting the current going to the magnet to attract or repulse another piece of metal in the speaker cone, the faster it moves back in forth, the higher the sound frequency. The minimum that a human can hear is about 20 times back and forth per second. The highest / fastest is about 20,000.

The larger the speaker cone is (especially subwoofer, or 2-way low end cones) the larger the magnet is required to be in order to move back and forth.

So, yes. Your speakers are large magnets. Large and very powerful, no refrigerator magnets in there.

Alright... so if both my computer tower and one of the PA cabs on the right of it are so close they touch each other, it's bad for the PC, right? Do you know if they are actually shielded? The Speakers... Thanks for the valuable info

Sorry about the bump, I tagged this thread as SOLVED too quickly, I just need a little more insight and a direct answer to my question, I'm still not sure if even though my speakers are huge magnets, are they shielded and would it be harmful next to my tower for my HDD ??

Thanks guys. I hope I get some feedback tomorrow morning, good night! :)

No, the magnets are *not* shielded.


And even if they were, do you really want to put a large magnet that close to a very magnetically sensitive HD?

One of the best ways to completely wipe a HD before you trash a computer is put it on top of a subwoofer for a few hours...
