Monoprice™Weatherproof Pro 5.25' Indoor/Outdoor 70V/8Ω 2-Way Speaker,(Each)Exceptional sound quality delivered in an easy-to-install speaker, designed for use in whole home audio systems as well as restaurants, bars, retail stores, and other professional installations.Perhaps the most versatile of all speakers from Monoprice™, the Weatherproof Pro series speakers are designed to provide great sound quality both indoors and out, and they are a great solution for either outfitting a restaurant or just adding some speakers to your patio.Aside from having an IP65 rating which allows the Weatherproof Pro series to withstand exposure to rain and humidity, each model in the Weatherproof Pro lineup also features a built-in transformer with multiple 70V taps that allow it to serve as part of a commercial background music and paging system, as well as having an 8Ω tap for use in traditional home audio systems.The Weatherproof Pro series speakers are sold individually so that both professional system integrators, as well as DIY home audio enthusiasts can order the exact number of speakers needed for the job—whether there's a need for three speakers, 3 pairs of speakers, or even 30 speakers. Monoprice™ is committed to bringing you the best products for the best pricing so you can do the job as efficiently and cost-effectively as possible!Since 70V speakers are connected entirely in parallel and do not require a connection in stereo pairs, you can easily connect 3, 6, 10, or more Weatherproof Pro series speakers without ever having to deal with crazy series/parallel wiring needed to keep the impedance within the range of typical 4Ω or 8Ω amplifiers. Of course, the built-in 8Ω tap still lets you connect these speakers to traditional 4Ω or 8Ω home audio amplifiers, so there's no need to buy a 70V amp if you already have a home audio system with enough channels and power to add an additional set of speakers.If you do have a home audio amplifier that has both A and B channels to power speakers in a second room, you can use that B channel to easily power a set of outdoor speakers. In fact, with just two channels of power from your amplifier and a Monoprice™ Speaker Selector, such as the SS-Pro 12, you can run several pairs of Weatherproof Pro series speakers as part of an ultimate outdoor listening area. Please see the full line of Monoprice™ speaker selectors to help plan your outdoor audio system when using 8Ω stereo amplifiers. If you plan to add additional amplification or want to have a separate audio system for your outdoor listening, consider using a 70V amplifier to make your installation easier and enjoy the benefits explained in the linked video below.IP65 rating against dust and water intrusion for all-weather outdoor use.5.25' polypropylene cone woofer.0.5' mylar dome tweeter.80W maximum power handling.Features 70V and 8Ω taps for use in both commercial and home audio installations.Full pan and the tilt-adjustable mount allows precise aiming into the listening area.Gold-plated binding posts for superior connection and longevity.Rust-resistant perforated aluminum grille.  .
