Yorkvill LS-720P (Yorkville LS720 P)
LS720P - 1x15-inch Compact Active Subwoofer
Delivering outstanding low-frequency performance, the 1500 watt (Peak) LS720P powered subwoofer has been designed from the ground up to be the ideal companion for any medium sized live sound or DJ PA. Intended for a variety of applications, the LS720P uses a single long excursion 15-inch woofer to deliver maximum output over the entire 40 to 150 Hz range.
The LS720P has sophisticated processing circuitry that protects the driver while maximizing the use of the available power. This processing has been carefully optimized to complement the characteristics of the driver and enclosure system. The fast limiter protects against clipping and over excursion. It is located with both high and low pass filters on either side of the limiter to guarantee that only the correct frequency content reaches the driver. The slow (RMS) limiter is equalized to adjust for the impedance variations of the loudspeaker system over frequency. This ensures the maximum output of continuous bass prevalent in today's music while ensuring protection of the driver against overheating. The carefully tailored attack and release times ensure that the maximum level is available from the system.
The input section in the LS720P allows for a variety of system configurations. There are two input sections allowing two signals to be blended into the LS720P. This allows stereo left and right signals to be summed into one LS720P while preserving channel seperation of the stereo signals. Each input section has XLR male and female jacks to allow loop thru of line level signals. In addition one input section also has two 1/4-inch jacks that may be used for loop thru of line or speaker level signals. Within each section all jacks are connected in parallel.
Simple controls on the LS720P include input gain (Volume), variable high frequency cut-off and low-frequency tunable bass boost. The variable high frequency cutoff is adjustable from 90 to 150 Hz to trim the subwoofer’s low-pass filter to match any full range cabinet. A low-frequency tunable bass boost adjustable from 45 to 90 Hz has been included to allow subtle customizing of the bass character.
Proven Class D amplifier technology allows the LS720P to operate without a fan while preserving ample thermal margin. The low heat dissipation of this technology eliminates the need for large, heavy heat sinks while the lightweight neodymium-based driver further reduces overall weight.
The LS720P uses a solid 5/8th-inch 11-ply Russian birch plywood cabinet construction with an all-metal heavy gauge perforated grille to protect the speaker and electronic components. Integrated all metal bar handles and metal speaker-stand pole-mount have been included.

élite Series Overview
Yorkville’s élite 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, élite systems are among the most advanced, most versatile and most efficient high powered portable P.A. boxes available.
Today’s élites, from the highly efficient two-way E10 to the 2400 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 Yorkville’s 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.
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 élite 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 élite 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 élite 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 élite 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 élite 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 élite 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.
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.

élite 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 élite system is always tuned and ready.
Rugged Driver Mounting System
All élite 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.
Rugged Black Carpet Covering
The stylish yet practical carpet that covers the élite cabinets keeps them looking great. The two part rubberized glue that is used to attach the carpet ensures that élite 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 élite 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.
Tilt back wheels and top-mounted handles are standard issue on the larger cabinets such as the E215, E2152, LS1208 and LS1004.
