Using the Lowell CP87 recessed enclosure is easy. First, find a suitable location for your 8 - inch speaker. If you're working on new construction, the extended flange will protect the opening as you work with plaster, concrete, or sheetrock. In existing construction or suspended tile ceilings, it's just as easy to install. When mounting, use the knockouts and clips provided. As for maintenance, keep the enclosure clean. You can use a soft, dry cloth to wipe it down regularly. Avoid using abrasive cleaners as they might damage the steel. Also, check the mounting from time to time to ensure it remains secure. That's all you need to know to get the most out of your Lowell CP87 enclosure.
