EF500P - 15-inch / 2-inch Active Loudspeaker
The EF500P redefines performance in a high-power professional active loudspeaker enclosure. Utilizing the popular élite EF508 as a base, and adding a total of 1000 watts (program) of bi-amped power and advanced signal processing, the EF500P is destined to set a new standard for active loudspeaker design. The woofer or low frequency amplifier uses Class D switching technology to reduce overall weight of the amplifier section. This solution allows the horn to produce loud clean transients to keep up with the high output of the woofer. The two-tier amplifier technology isn't typically seen in a product like this, however we found the advantages (lower weight, more efficiency, higher headroom and lower operating temperature) made it a perfect choice for powering the top end.
This combination of amplifier technologies keeps distortion to a minimum while reducing the heat dissipation to a level low enough to eliminate the need for heavy heatsinks for the overall power stage. As an additional advantage, our unique combination of two-tier and Class D amplification has reduced extraneous heat to the point that EF500P can easily be used in any orientation, and close to walls, floors and in close arrays with multiple cabinets. We have found that competitive active loudspeakers with large finned heatsinks need to be operated vertically and with clearance to ensure proper heat dissipation and ventilation. Since the EF500P is ideal for flying in large clusters and in point source concert sound systems, our designers took extra care making sure that in tight clusters overheating would not be an issue.
We've also found an opportunity to tweak the electronics for maximum overall speaker performance and protection. Borrowing some ideas from our powerful and popular TX Series PA systems, the limiters used in the input and crossover stages are a complex combination of gain reduction and sweeping filters. As the EF500P is being pushed to its maximum input / output levels, it's advanced filtering begins rolling off unnecessary subsonic frequencies. In addition the processing protects the individual components ensuring failure free operation even after long term operation at close to maximum output levels. The filter has remarkable (less than 70ms) response times, allowing the system to constantly be retuning itself to make sure the output is as clean, as loud and as clear as possible at any given moment. This is achieved without negatively affecting the overall sonic quality of the cabinet. This ensures that the essential part of any mix, like the vocals or solo instruments, come out clean and clear when the cabinet is being operated at the extremes of power and woofer excursion. Extremely fast and accurate limiting is in place to protect the speaker components.
The EF500P has a built in mixer allows the loudspeaker to be used directly with a microphone and / or line source. The loop output allows additional active cabinets to be driven from one cabinet's mixer stage, or a series of cabinets to be driven from one source. If desired, the end user can combine a pair of the EF500P's using the mixer inputs on each cabinet and coupling the loop outputs. In this simple example you would have the ideal presentation system with two microphone inputs, two line inputs optimized for CD, Cassette or laptop computer audio source, complete within two speaker cabinets. Many of our active cabinets can be linked together but a maximum of three 'mixers' can be active at any one time. (Making three mic sources and six line sources available in any three or more cabinet array). The microphone input has equalization and high pass filtering appropriate for vocal applications. The trim control allows looped cabinets to be individually adjusted in level. This is invaluable in applications where large numbers of cabinets are used such as clusters or in trade show applications or when EF500P's are used as repeater cabinets or for side fill. The 100 Hz high pass filters allows the EF500P to be used more efficiently with any active subwoofer.

The specs on this speaker are very impressive.
Some Manufactures use +/- 12DB and Give you a Rating of 40 HZ to 20K that is not impressive at all. Just to let you know just about any speaker on the market can do that. But when you have a speaker perform from 50 Hz to 16k and roll off only 3db and deliver a max sound pressure level of 133db WOW. That is incredible balance of High Freq Mid Freq, and Lows Freq. My degree is in Electronic Engineering and I love high quality sound.
If you want the best self powered speaker on the market. the EF 500P is the box. This is what I recommend to my Family and Customers that have been shopping with us for over 17 years. Once you own a Yorkville product you will understand why they are a huge company without huge advertisements. We know our customers and we know what they want. Quality, dependability, exceptional service, and the lowest possible price. Yorkville is the brand we used to build our business. It's the brand that keeps our customers coming back and asking for more. Backed by a two year even if you break it warranty.

User Warranty Claim Procedure
As a Yorkville product owner who purchased the product in Canada or the U.S.A. you should be aware that there is an UNLIMITED 2-YEAR "EVEN IF YOU BREAK IT" WARRANTY on most of the products that we make. Furthermore, we don’t care if you bought it from an authorized Yorkville dealer or if it was new when you bought it. As long as it is an electronic product or speaker system of our manufacture which was purchased by a dealer or end user as a new unit within the past two years, or first rented as a new unit within the past two years, you are covered. That’s virtually all there is to it. What voids the warranty? Virtually nothing voids the warranty*. In simple terms, if it needs repairs for any reason during its 2-YEAR warranty period, it is covered.
If you have difficulty determining whether or not something is still under warranty, simply note the manufacturing date contained in the serial number, then add two years to obtain a feasible expiry date. When there is no other proof, that is what we do. In our serial number system, the year of manufacture is the first digit, and the month is next two. For example, serial number "701----" would date from 1997, month 01 (January). A feasible expiry date would therefore be January 1999.
* As expressed on our warranty card "Freight charges and damages caused as a result of major accidents or natural disasters (such as fire, automobile wrecks, tornadoes, etc..) are excluded from this warranty."
HOW TO MAKE A CLAIM:
Simply contact the dealer you purchased the product from. If that dealer is either not willing to help, or is not an authorized dealer you can contact us directly. We strongly suggest that you try to keep the dealer involved. They have better access to shipping resources, and are often able to fix the product locally, and file a warranty claim with us. This dramatically reduces down time.
We do not have "Authorized Service Centers" that are not in some way linked to a Yorkville dealer. If you must send merchandise back to us directly, we suggest you contact us first. You can reach our service departments at the following addresses:
