2. The speakers (Speakers Drivers)

The selection of speakers (Speakers drivers) can be a really complex task given the number of manufacturers and a variety of speakers available to everyone. Have to make criteria for the selection of appropriate speakers.

Among trading houses can find several lines of products, each aimed at a different market sector with specific characteristics. Normally there are three sectors, the speakers for the professional world (for speakers of listening rooms, auditoriums, theaters, concerts, etc..), Speakers for the automotive world (the so-called car audio) and finally, those engaged Hi-Fi systems (consumer equipment, study etc). It is precisely in the third group where we must focus our attention to the selection.

The goal is to repair some old speakers with the lowest cost possible, ie we need to replace the speakers and keep the box, everything else a normal design process, selected the speakers is calculated the appropriate box for them. Should not select high-quality speakers when we can not optimize the site to extract optimal performance.

The availability is also important, so I opted for a national brand, Beyma ( www.beyma.com ) widely distributed and many years of experience. Specializing in professional speakers have a midrange series called Studio that fits the profile of the speakers you need.

Inside the Studio series dismiss all speakers with polyurethane foam suspension and focused on the rubber that are more stable and less dynamic rate of deterioration over time. For the low (woofer) 8 "I selected the 8WOOFER-PE and the media (mid-range Squawkers) the 5MP60-N 5-inch, both have polypropylene plastic cones to avoid partial oscillations or resonances membrane, providing a flat response in its working range and good impulse response. Show a high efficiency 92dB and 91dB respectively. Mounted on an aluminum chassis with a ferrite magnet are designed to work interchangeably in sealed enclosures or bass-reflex. You can easily find at any electronics store, specializing in Hi-Fi or Internet to a very affordable price.
