I've had quite a few requests for a small high sensitivity speaker
good for either hi-fi mains, control room monitors or, most especially, home
theatre. One of those requests came from me. Ever since I
outfitted my HT with TLAH mains and a Table Tuba sub I wasn't able to hear
the center channel well enough, as the 87dB sensitivity of my MTM center
couldn't keep up. So was born the SLA: the Short Line Array.
At 28 inches tall it may be shorter than most line arrays, but in sensitivity
and response it's right up there with the big boys. Here's an SPL chart:
Here's a review, by builder Gavin Humphrey:
Well, I'm finally done building my pair of SLAs. They look awesome! Had my
audiophile buddy give them a listen they other day and thought they sounded
GREAT, smooth through all the frequencies.Great plans, fun build! Over the
summer I'll build an auto tuba to go along with them.
What I really love about this cab is that I built it with closeout midbasses
that cost 49 cents apiece and tweeters that set me back a whopping 24 cents
per. The entire project including wood cost less than thirty bucks. Whether
you'll be able to find drivers that inexpensive I can't guarantee, but even at
ten times the price you'll save big time compared to what it would cost to buy
a speaker of this quality.
You can build the SLA flat face as pictured above for vertical mounting, or in the curve
face version shown here, for wide dispersion in a horizontal placement.
Also included is the SLA Pro PA top. Measuring 29 x 11 x 9.5 inches, it's the
right size for smaller gigs, like weddings and corporate events, or for DJ
monitoring. Loaded with four Eminence Alpha 6 woofers and a four or six element
tweeter array, it's got the output and pattern control that line arrays are noted
for, in a size that's easy to carry.
