Sound System

Any tips? We're moving from 3500sf to 9000sf and think I'm going to need something bigger. We have a Bose system now, but I can't add additional speakers to the system.

Help?

Just turn up the volume to eleven.

Re: Sound System

With 9000 sq ft you might want to start looking into pro-audio type equipment. Go to www.partsexpress.com (WFS) for good audio gear at great prices.

Re: Sound System

Time to move to some pro-audio PA speakers. Bose ain't gonna cut it; home-style speakers are way too inefficient for that much space. Bose is especially notorious for inefficiency. Look at brands like Yamaha, Peavey, JBL, Electro Voice, etc. You need to be shopping at places like Guitar Center instead of Bob's Stereo Palace. You don't need more speakers so much as bigger, more efficient speakers.

"Typical loudspeaker sensitivity is 85 dB SPL/W/m for home stereos, 95 dB SPL/W/m for small PA speakers, 100-105 dB for medium PA speakers, and 110 dB for large PA speakers."

Keep in mind that an increase of 3db of loudness (which ain't much) requires DOUBLE the amplifier power. Put another way, twice as loud requires ten times more amplifier. Driving a medium size PA speaker to 100db at a distance of one meter requires one watt but for your Bose speakers it requires 32 watts. That same 100db of volume at one meter becomes 80db at 10 meters. At a distance of 30 meters -- which is what we're talking about here -- that 100db becomes 70db. Orchestras go as loud as 100db, live rock shows go up to 110-120db.

Re: Sound System

Actually I am glad this has come up as I am struggling to find an affordable system that will have some boom. My building sits in that size range where a cheap system won't cut it but I don't have the money for a large PA. Any suggestions on where to go?

Before anyone says it I watch Craigslist like a hawk and haven't found anything yet and I am also fearful of buying used like that.

Re: Sound System

Key thing is that your new space is two and a half times larger. This means you'll need something like five times more sound power.

I can help by taking that Bose system off your hands. Should sound sweet in my garage gym.
