Best garage speakers

High efficiency horn loaded speakers are used for concert and theater PA systems quite effectively.  They can fill large areas without sounding strained and have great dynamics.

In that price range some slightly scuffed up Klipsch Forte I or II's with 98 dB sensitivity and frequency response down to 32 Hz would be good candidates, but worth trying even if they are priced a bit higher. 

Remember, a rather equivalent Forte III retails for over $3000 and are quite popular.

Good luck.

I see millercarbon beat me the Klipsch Heresy, which is a great recommendation, but they would benefit from a subwoofer.  The Forte is basically a larger Heresy for better bass extension with the same midrange and tweeter setup.

Older VMPS Tower II, or SE if you can find them. Dual 12", with 12" PRs
tunable for ANY room, or amp.. 12" sub, 12" mb (options there too), 12" PR.

They have everything, 19hz - 20k + They will fill 900 sf with ease.
The BASS will blow your mind, mids there are a few options and the highs are split between an inverted dome and a true ribbon. Actually a 5 way speaker, with 1st and second order XO, Bi ampable.
500 + watts 115+ db
or 25-75 goods tube watts (I used MC 240-275) push them just wonderfully.

BTW NO need for a sub, they really have it all, for the money. BIG boom boom in the room room.

4-700.00 about 100-120 lbs depending on the upgrades. They are a true reference speakers...

They can play chamber music to Rock and Roll
Z Z TOP, get down boogie...and right in to Island music...

Regards

Try these, they will be perfect for your garage. And if you smooches the designer, he will autograph them at no extra charge :-)
