You don't get better efficiency with a Linkwitz transform on a sealed enclosure. You will actually be throwing away 10 or so dB of signal somewhere in order to EQ the low end.
For example, if you put a 96dB sensitive speaker in a sealed box and intended to use a 4 Watt amplifier, with no EQ, you'll reach the desired 102dB of output.
If you put in a 10dB active equalizer ahead of the amplifier to flatten out the FR, the amp will clip at low frequencies long before it would have clipped with no EQ, and you might find that you can't get 96dB of output from your 96dB speakers with your 4 Watt amplifier.
Follow Ups:
For the sake of argument, I can't imagine anyone applying a LW transform to a speaker with 96db sensitivity. The tradeoff for practically zero bass output (for increased efficiency) has already been set by the choice of driver's T/S parameters.
Mike likes to talk about the Linkwitz speakers and the LXmini is a great example of the tradeoff between size and efficiency.
The recommended power for this little guy is four 80 watt amps!
