Bose FreeSpace FS4SE

Our take on the Bose FreeSpace FS4SE

The Bose FreeSpace FS4SE is a surface-mount, weather-resistant loudspeaker built for outdoor and commercial installs. It uses a single 4.5-inch full-range driver rated at 50 W RMS (200 W peak) with 89 dB sensitivity and an 8-ohm load, so a modest amplifier can drive it. A 6-pin Euroblock connector with loop-through simplifies daisy-chaining multiple units. The best new price is $399 at eBay as of November 4, 2026, with 4 stores listing it new.

Questions and answers

Is the FS4SE worth $399?

It is a commercial-grade outdoor speaker with loop-through wiring and weather resistance, which justifies more than a consumer Bluetooth speaker. At $399 at eBay as of November 4, 2026, compare against other 4.5-inch surface-mount install speakers before buying.

Does it need an amplifier?

Yes. It is a passive 8-ohm speaker rated 50 W RMS, so it needs an external amplifier. The 6-pin Euroblock with loop-through lets you chain several units from one amp channel.

Can it be used outdoors in rain?

Bose rates it weather-resistant for surface-mount outdoor use. Mount it under an eave or with the connector facing down to protect the Euroblock terminations.

How low does the bass go?

Frequency response is 70 Hz to 17 kHz at -10 dB. That covers music and speech but not deep bass, so add a subwoofer if you need low-end punch.

What is in the box?

Expect the speaker, mounting bracket and hardware. The Euroblock connector is on the rear; speaker cable and amplifier are not included.

When is it cheapest?

Install-audio pricing moves with dealer stock. The current best new price is $399 at eBay as of November 4, 2026; check the price history for dips before ordering multiples.
