Greetings , Im in process of moving into a 2,000 square foot warehouse and desperately need some good sound. I'm planning some build outs and remods etc including lighting , and Acoustic Treatment. Acoustic will probably be a combo of homemade flat panels with insulation and or towels or the like and some eBay Specials. Thinking I'll run a row or two along walls and a suspended array of vertically organized sorta deal thing's my first time. SO, I Have very little money to invest and will upgrade over time but to start with stereo, my idea/plan is to use my computer ,5 year old large IMac and a stereo reciever which I do not yet have, buy speakers and whatever other components needed, and build all of the speaker boxes.any recommendations on power/reciever ? OK so , I have a flat ceiling at 20 feet off the deck, layout is rectangular roughly 30 feet wide 70 feet long with a small office restroom area with 8' ceiling and 10x20 area next to a 12x12 metal roll up door. I'll likely build a second story office on top of this area, and an additional free standing mezzanine type structure either in the back or in line with office area, fwiw. Can anyone offer a little info and point me in a good direction? I really appreciate good sound, however I don't know much about building a custom setup . Keep in mind, My budget is as little as possible. While hoping to get some decent clean sound. At least not horrible. Is this feasible? I work with my hands, design build anything nearly, wood and metal. I grew up in a cabinet shop , and would love to create some super radical speaker boxes. I've heard about the 70amp speakers, volts? The many small ceiling speakers. I'm thinking 3 way speakers or maybe some mids and highs in arrays. Considering making 8 or so ? Idk. Heeelp

Well, all in all, fewer speakers is better... one pair could be worth a whole lot more than 8, posted on January 20, 2017 at 13:46:35
3+4=5
 I would not go with 8 cheap speakers. Rather find one pair or make one pair of high efficiency speakers. Plenty of books on how to make speaker enclosures and match the speakers to the enclosure. 'Madisound' has lots of parts and info.
This saves a ton on crummy wiring all over the place. Plus then you have one better stereo amp instead of some cheap home theater stuff.
Locate the speakers so they can be heard perfectly from your 'usual' hang out place. Don't worry too much about everyplace else.

The one thing I would think you might want is to be able to adjust the volume ANYWHERE in the shop. So location of the preamp.. or a infrared remote repeater should be in your budget

 I would agree with 3+4=5. I've had shops like that and I always use
just 2 high eff. horn setups on the far end (not sidewalls), that
way you're always in the sweet spot. Old PA stuff works great and
also cheap, i.e. ... JBL 4560's (many clones out there) can be had
for under $200./pr. loaded, or $100. for empty cabs. Many horns to choose
from to mount on top. You won't need a big amp, I've never needed
over 40 WPC and that's with loud classic rock.

If you don't go the bass horn route, two 15" + tweeter horn per side
would do it, but with 100 WPC+. Check Craigslist for used PA speakers,
sometimes at bargain prices.

 If understanding words spoken through the system (or if preserving the original source as much as possible) were the desired outcome, then what you should look at are 2 large horns like an altec VOT or other .

There are important parts of reproduced sound which are very time sensitive (like understanding words and producing a mono phantom / stereo image) and so one finds all things being equal, that the more sources of a signal that arrive at your ears, the worse intelligibility and such are.

If you got a horn based system and positioned it so that as little sound as possible was hitting the walls, that this will minimize the need for acoustic treatment.
Also, one finds in commercial sound that the larger the space is, the more important this stuff is because as the room size goes up, the cubic volume of air (where the reflected / stored sound energy is) goes up faster than the surface area where the absorption is so the bigger the room, the more stored energy there is.

Anyway, it comes back to an old sound system adage "put the sound where the ears are and not the walls or ceiling".
If you don't have directivity on your side to control reflections, the only other option is large scale room treatment.

If your a computer program guy, you can get the feel for how it's done where i work. This is a video about a free design program used to figure out the best locations and directivity patterns when designing a larger venue.

 My old listening room was in the upstairs of a 100 year old barn. I have had a myriad of speakers up there including a pair of Klipsch La Scalas, Snell Type A and the list goes on. I always did stereo and was usually impressed with what I heard. I built a pair of line arrays out of 3" speakers with 16 per side roughly based on the parts express link below except I used 8" pvc pipe and put in a port out of the bottom. They had 2 major advantages over my La Scalas. They were easier to move and there was no worry about if the crossover was correct. I had various people come and listen and they always agreed that the line arrays sounded better. As far as an amplifier I recently bought a nuforce dda120 off of amazon and I am not looking for something new in a very long time just hook it up via the optical out on your iMac (you will need to get a mini toslink to toslink adapter) and you should be good to go... with a little scrounging I am guessing a total budget of around $600 should surround you in good quality sound $300 for the speakers and $300 for the amp.
