Wireless speaker manufacturer Sonos is in discussions about a move from East Cambridge to Lafayette City Center in downtown Boston.

The audio company is negotiating for 110,000 to 130,000 square feet at the mixed-use complex near Downtown Crossing, according to real estate sources. State Street Corp., the previous office tenant, vacated the building in favor of its new 500,000-square-foot One Channel Center complex that opened last month in the Seaport District.

The Abbey Group of Boston is repositioning the 610,000-square-foot complex to attract new tenants and add ground-floor retail and entertainment venues. Florida nightclub group Latitude 360 has signed a letter of intent to open a 63,000-square-foot dance club at Lafayette City Center, the Boston Business Journal reported last month.

The complex’s makeover includes a modern lobby with a glass staircase, marble walls and an "edgy" 360-degree security desk, according to marketing materials. Office spaces will offer flexible layouts, open floor plans and high ceilings.

Online back-up company Carbonite also has leased 50,000 square feet in the building, with a planned relocation from 177 Huntington Ave. in Back Bay later this year. A spokeswoman for The Abbey Group said she could not confirm any leases being signed.

The building repositioning is designed to feed off the development boom in the Downtown Crossing area, anchored by the 1.1-million-square-foot Millennium Tower project and renovations to the former Filene’s building which will include a Roche Bros. supermarket and Irish retailer Primark.

Founded in 2002, Sonos manufactures wireless speakers, home theater systems and accessories. In addition to the 25 1st St. location in Cambridge, it has a West Coast office in Santa Barbara.
