LS1208 - Subwoofer - 1200w, 18 inch
A two year investigation into the optimization of high output low frequency sound has yielded the LS1208 "basspipe" subwoofer system. The "basspipe" is a multiple flare horn, connected to an organ like pipe, slowly flaring to the mouth. The bandwidth is narrowed, optimized to a specific range in the lower registers. Outdoor measurements show very smooth, very high output in the 35Hz to 200Hz range. This is the highest efficiency that we have ever seen for a single 18" driver enclosure, especially with a gross volume of only 22 cubic feet. In addition, a significant gain is achieved when using two units side by side as the mouth nears maximum acoustic load.
Additional research has developed a woofer with significantly higher power handling than any other speaker that we currently use, making the LS1208 one of the highest output subwoofers available at any price. Performance, packaging, and overall value make the LS1208 a benchmark.
Suitable for touring or fixed installations, the cabinets are constructed of 15mm 11-ply Baltic Birch with heavy internal bracing for reduced resonance and better durability. The enclosure is covered in a black carpet covering and incorporates metal corner protectors, rugged curved anti-resonant metal grilles, and 1/4" or Speakon input connectors. An optional finish of black ultrathane paint (LS1208B) is also available. Additionally, the Speakon connectors feature a configuration switch which allows instant reversal of Speakon jack pinouts for easy single wire hook-up using optional four wire Speakon cables. The LS1208 includes tilt-back wheels and top/rear mounted corner handles for better maneuverability and stacking (wheels don't fall in the handles!!).
lite Series Overview
The Compact & Complete Solution Yorkvilles lite series loudspeaker systems are the result of years of research, pushing the limits of modern state-of-the-art sound reinforcement technology. Engineered for the serious pro audio user, lite systems are among the most advanced, most versatile and most efficient high powered portable P.A. boxes available.
Todays lites, from the highly efficient two-way E10 to the 1500 watt E2152 have some of the most advanced component protection and crossover technology available today. They have been carefully designed to bring you the latest in Yorkvilles advanced loudspeaker engineering.
Ideal for any small PA rental house, installer or sound company, these loudspeakers may replace a number of specific application cabinets in any inventory.
Modified Trapezoidal Shape A modified trapezoidal shape and recessed input jack panel and handles mean these cabinets can function perfectly as a wedge monitor or front-of-house loudspeaker. Unlike some multi-function loudspeakers currently in the marketplace, great care has been taken in the design process to ensure that lite cabinets will perform without compromising functionality as either a monitor or a front-of-house enclosure. Neither application was considered as an afterthought.
Several of the lite loudspeakers are loaded with 80 x 50 rotatable ABS Waveguide horn assemblies (the E10 utilizes a 100 x 25 horn). The ability to rotate the horn assembly ensures that the cabinet can provide optimum high frequency dispersion when the loudspeaker is used in either a vertical, horizontal or arrayed application.
Integrated stand mount adapters and flyware means these enclosures can be utilized in any permanent install or touring application. In addition, the modified cabinet shape means the lite series can be installed much closer to vertical surfaces and in some cases, under balconies in tight locations, and can be arrayed in a much tighter less obtrusive cluster.
Of course, the lite series has retained the features and high quality sound that have made them so popular including Yorkville's famous two year (even if you break it!) transferable warranty.*

Advanced Crossover Networks and Protection Schemes
The majority of the lite range feature seamless driver interaction through sophisticated high-slope passive networks and ingenious component protection schemes. Rugged jackplates are inset and include a combination of both Speakon and 1/4" phone jack inputs.
Advanced PTC Horn Protection makes its debut in the lite series.
PTC is an ingenious current sensing / self resetting breaker that offers some serious advantages over current protection schemes used in many loudspeaker cabinets. This protection scheme, while always present in the signal path, remains inaudible until it becomes necessary for it to react. It kicks in at a point where it effectively reduces output to the horn and protects that diaphragm from damage due to excessive power input or signal distortion. Unlike a breaker it does not require a physical reset to allow signal back to the horn driver, and unlike a bulb or fuse, does not need to be replaced if the circuit is tripped, and the fuse is blown.
Under the hood of an E152 Where PTC shines is in heavy feedback environments where most horn diaphragm damage occurs. In rare situations even where a microphone might be dropped in a monitor, the sustained squeal can destroy diaphragms in seconds. PTC will significantly reduce output level to the horn to protect the diaphragm. When the situation has been rectified, and the feedback eliminated the horn will return to full operating level within half a second.
The E2152 features the ATP (Active-Transistor) protection system, which allows the horn driver to operate at levels significantly above those required for normal operation. The ATP brickwall element of the protection circuit uses power transistors configured to operate linearly yet have the fast attack required to protect against harmful transients. Along with ATP, the crossover also incorporates air core coils and polypropylene capacitors to guarantee reliable and distortion free operation at extreme levels. The sonic benefit is higher output and greater transparency when operating at high levels.
lite Series Characteristics
Full function stereo analog processors that are configurable for passive or bi-amp operation, as well as live or recorded music applications make sure that your lite system is always tuned and ready.
Rugged Driver Mounting System
All lite cabinets feature a specially reinforced driver mounting system that makes sure the horn drivers will still be attached to the horns when you get to the show. The ABS or composite horns are pressure fitted to the driver which is bolted to the internal driver support.
Custom Design Horns
Custom ABS plastic and composite horns are specifically designed for each cabinet and manufactured right in our factory for optimum quality control. This insures proper waveguide output for better clarity and lower distortion.
E2152 Cutaway ImageRugged Black Carpet Covering
The stylish yet practical carpet that covers the lite cabinets keeps them looking great. The two part rubberized glue that is used to attach the carpet ensures that lite cabinets will stand up against moisture by effectively wrapping the cabinet in a rubber glove.
Curved Metal Speaker Grilles
Curved metal grilles absorb shocks evenly to resist dings and dents while eliminating frequency resonance. The trapezoidal cabinet shape allows for arrayable performance without phase cancellation.
All lite cabinets feature attractively recessed bar handles. Great care is taken to make sure that they "stay out of the way", but are easy to get at when you need them.
Flush Mounted Stand Adapters
Flush-mounted stand adapters in the top of the subs and bottom of the full-range speakers allow the use of the adjustable SW-TELETUBE option which makes setup a breeze by eliminating the need for speaker stands.
