Is it a problem to take your JBL speakers with you to the beach?

Here is a selection of 7 inflatable speakers:

Excerpts from the description of the HotAir speakers:

They can be collapsed completely for travelling, but you need to blow them up to tune in.

Each set of speakers includes an amplifier, a battery back and a AC adapter. The Inflatable Speakers can be used in connection with various pieces of equipment, including most Personal CD Players, Personal stereos, MP3 players and Mini Discs and are PC and Mac compatible.

Each speaker measures approximately 17.5cms in height, when inflated. Base measures 11cms x11cms.

PS. I have no commercial interest in the HotAir speakers, and I have no idea how they sound.
