F57SP-8

8" IsoFlare bookshelf speaker — F57SP Special Production Series. The F57SP-8 is a 2.5-way center-channel loudspeaker from Fyne's Special Production range, using an 8-inch IsoFlare point-source mid/bass driver, an 8-inch active bass driver, and an 8-inch passive ABR radiator, topped by a 25mm magnesium dome tweeter. It handles up to 400W peaks and is designed to partner with F502SP floorstanding speakers or the F700 Series in large home cinema installations.

Technical background

The F57SP-8 uses an 8-inch IsoFlare coincident driver — the same driver size as the flagship F1-8 standmount — in a flushmount architectural housing. This provides 42Hz low-frequency extension and 92dB sensitivity, enabling the speaker to cover large volumes without the bass reinforcement limitations typical of in-ceiling designs.

Design story

Developed as the reference-level member of the F57SP in-ceiling range, the F57SP-8 was designed for projects where compromising on acoustic performance is not acceptable — luxury residential, premium hospitality and high-end commercial installations.
