{"product_id":"lowell-es-4-rtr","title":"Lowell ES-4-RTR Steel Trim Ring for 4 Inch Speaker Retrofit","description":"\u003cp\u003eThe Lowell ES-4-RTR is a steel trim ring designed for integrators and installers retrofitting the ES-4T speaker into existing 8-inch speaker enclosures. Rather than replacing an entire enclosure, this ring allows a 4-inch driver to seat correctly within a larger cutout, preserving the existing infrastructure while upgrading or replacing the speaker element.\u003c\/p\u003e\u003cp\u003eThis trim ring is suited for installed sound environments such as classrooms, conference rooms, hospitality spaces, and houses of worship where older enclosures are in place and a full replacement is not practical or cost-effective. The white powder epoxy finish blends with standard ceiling and wall surfaces for a clean, professional appearance. Hardware and rubber bumpers are included, covering everything needed for a complete installation. Refer to the Lowell spec sheet for required enclosure dimensions before ordering, as minimum enclosure depth applies.\u003c\/p\u003e","brand":"Lowell Manufacturing Co.","offers":[{"title":"Default Title","offer_id":52446001660088,"sku":"32775","price":29.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/32775_LOWELL-ES-4-RTR_ALT01sqr.jpg?v=1785181519","url":"https:\/\/soundpro.com\/products\/lowell-es-4-rtr","provider":"SoundPro","version":"1.0","type":"link"}
