You can get decent low end response if you EQ enough small drivers. The Bose 901 and Russell IDS-25 speakers are examples. Neither, however, would be considered efficient given the amount of low end boost applied to each.
My point to Mike is that you will not find small, efficient speakers with good first octave response. You'll have to trade off something.

If too much system efficiency is sacrificed to achieve the goal, then it's time to re-think the design approach. IMO. :)
Multiple drivers addresses the issue, but...
Equalizing "full-range" drivers/systems (like the Bose 901 or IDS-25) represents a worst-case scenario because every db of EQ applied to the lower octaves reduces the overall system sensitivity directly by a like amount. But, only if your program material contains much information in the lower octaves. (Trade-offs are everywhere.)
However, generally, drivers are equalized only with their passbands in mind in multi-way overall design. So, you don't sacrifice much from their "nominal" sensitivities.....relatively speaking.
Speaking of systems that sacrifice a large amount of sensitivity as a result of extreme equalization, this one springs immediately to mind:
