SLA Stereo/Home Theater Speakers

The benefits of a line array are high sensitivity, wide horizontal dispersion, and a high degree of vertical pattern control. Can you get those benefits from a line array that doesn't run from the floor to the ceiling? The answer is yes. The SLA, Short Line Array, takes the line source concept to the small end of the scale.

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.

The standard SLA may be built with four 4" midbasses in a 19 inch high cabinet, or with six 4" midbasses in a 28 inch high cabinet. If space is at a premium build it 15.5 inches high, loaded with four 3" drivers. Also included is a two driver surround speaker version.

If your room won't allow for a vertical home theater center the CurveArray version gives the widest possible dispersion from a horizontal multi-driver cabinet.

The CurveArray may be built with six 4" midbasses in a 31 inch wide cabinet, or nine 4" midbasses in a 46 inch wide cabinet that will meet the center channel output needs of any home theater. At the opposite end of the size range it can be built with four 3" drivers at 16.5 inches wide by 6.5 inches high.

All seven versions are contained in the SLA plans.

SLA PRO PA TOP

The SLA Pro is the smallest line array format PA cab available, delivering high output with extreme clarity in a compact package.

The standard six inch woofer version may be built with two Eminence Alpha 6 in a 15 inch high cab, or four Alpha 6 in a 29 inch high cab. The micro four and five inch woofer versions may be built with two Eminence Pro 5W in a 13 inch high cab, or four Alpha 4 or Pro 5W in a 25 inch high cab. It's the right size for smaller gigs, like weddings and corporate events, or for DJ monitoring. For larger gigs they can be stacked, in both straight and spiral array configurations, for either maximum throw or maximum horizontal dispersion. For Line array speakers dominate the world of pro-touring sound, because they work better. SLA Pro puts the advantages of line arrays within the reach of every band and DJ.

Construction Degree of Difficulty: 4

Performance Quotient: 8

Suggested subwoofers: Tuba 24, 30 and 45, Titan 39. Equivalent Retail Value: Two midbass version $449, four midbass version $899.
