Loudspeaker

In this post I will consider potential choices for the loudspeaker to be included in the design of my DMI. It is important to note that technical it is the loudspeaker drive unit that I will be including, this is useful to know when searching google etc.

I figure I need a loudspeaker which focuses on frequency response, but which also has a reasonable amount of power ie for playing in the studio. External speakers would naturally be used for filling live performance spaces. Size is also an issue since recent designs of my Cajon have been small enough to be played between the knees or on the lap. The speaker therefore needs to be of a reasonable weight and size to allow this.

The main contender so far is this speaker from Visatron, available through RS. The technical spec. is available here. Its 6.4cm/2.5inches and is described as a full range speaker driver. It has a typical impedance of 8ohms (the literature suggests this is the norm) and a power of 8W. Is this a good power level?
