Surprisingly it features a dedicated 3.5mm out so you can connect it to an external woofer.
Unfortunately all compact speakers make some sacrifice in order to accommodate chic proportions, and the FoxL's is in the treble. On some occasions the speaker would slightly distort, shattering its faultless image. In its defence, distorted audio was the by-product of maxed-out volume and it could be hedged by dropping the levels down a notch or two.
Bass heavy genres perform particularly well on this speaker, with it shining when it comes to mellow tunes, but if you're playing rock or metal, which are characterised by dense high notes, its performance will underwhelm.
The speaker's skidding is a bit of a nuisance but it can be kept grounded by using a sticky matt. The effect intermittently occurs and is instigated by volume, genre and above all, the surface it's sitting on.
Also included in the pack is a lanyard, pouch, a gold-plated auxiliary cable, a mini-usb cable and a mains charger with various travel adaptors. It's a well-equipped product which makes the $280 price tag a little more bearable.
If you're after great sound harnessed by slender proportions, the FoxL speaker deserves consideration. Audiophiles will be impressed by how much sound it tastefully produces; however, I'd do away with the Bluetooth variant and pick up the cheaper "Purist Speaker" model instead.
