2 Speaker Setup for a large office presentation space

We have an office with 58' of floor space where we will have a projector and projection screen.

We are looking for a 2 speaker setup to produce clear enough volume for the entire floor space.

You say 58' of floor space - do you mean 58 square feet? That is only 7 feet by 8 feet - I would hardly call that "a large office presentation space" - is it actually bigger than that?

A question I have is what type of electronics will be driving this setup? A computer sound card output like most presentation rooms?

Also, do you have any space restrictions on equipment to drive the speakers and is there any kind of wire already run to the speaker locations?

Assuming that a computer and its sound card output will be driving the presentations, at the minimum, you will need an amplifier and a pair of loudspeakers. If the space is really large, bigger speakers or possibly two pairs will be needed.

Another way to go would be to use powered speakers, but this would require a wall power outlet near the speakers - is this a possibility?

A nice feature to have on an amplifier is auto on - when the amplifier sees an audio signal it will automatically turn on and after several minutes it will turn back off. Nobody could forget to turn it off. My favorite small amplifier is the Parasound Zamp and it does have an auto on feature and the newest v.3 version has 45w per channel which will be more than enough.

For speakers, you will need a proper spot to place them like a shelf. If this is not available, speakers with a wall mount socket will allow easy wall mounting. Something like the NHT Super One or the Classic Two (these available in both black and white) both of which have built in wall mount sockets.

It's about 58 feet deep in length, and 40 feet in width.

I was thinking about putting two large speakers against the wall where the projection screen will be hanging from.

Thanks for the good info.

I'm wondering if the NHT's are too small for a large room thats ~60' deep, 40' wide?

Again, what is the purpose if this setup? Is it just a work presentation? Watching movies? Hi quality music?

What's your budget? Does the budget need to include an amplifier?

Yea, 2400 sq ft is a VERY large room - if I was using just two speakers at one end I would almost want PA type speakers and more power - maybe JBL speakers like the JBL Control 5 or Control 28. If you need louder, get some JBL Eon live sound speakers (either Eon 315 powered or Eon 305 passive with a separate amp). This would work for speech or non-critical music listening

Critical music listening or movie sound would require another direction - like some very sensitive large speakers made for large spaces - maybe JTR speakers and 100w+ amplifier power.

JBL 4722N. 58' long room is not an issue with any of the JBL Pro Cinema speaker.

How about Triad? They make speakers in every size and configuration imaginable. They will even customize if necessary.

For a room that size I would recommend the following models:

InWall Bronze/4 LCR: http://www.triadspeakers.com/products/iwb4lcr.html
OnWall Bronze LCR: http://www.triadspeakers.com/products/owblcr.html
InWall Silver/4 LCR: http://www.triadspeakers.com/products/iws4lcr.html

All of the above can be custom paint matched to blend into your wall color.

Authorized Dealer Sales: Triad Speakers, NHT, Marantz, Denon, JVC, Stewart Filmscreen, Screen innovations, Panamorph and Control4.
