I never heard that rule. I have some rear ported Mission 765's that are stuffed pretty substantially with fiber-fil. After everything the highs are much smoother and the low end is cleaner, tighter and deeper. Bass notes are more musical and less LFE, meaning it's easier to follow the melodic line of the bass. I had been using a sub to carry (and remove the load from my main amp) frequencies under 80 Hz which is definitely no longer needed.

My pair of CF-2's have plenty of volume, detail and bass. You need to review them with the best recorded material you can find. Loreena McKennitt is spooky good. One thing I did do was remove the horns and damp the inside surface with silicone. Other things I did were to affix to the inside surface of the cabinets a few roofing tiles (all but the top), but anything that creates a more non-resonant surface is good. Lastly, I took out those cheesy foam pads and stuffed the cabs with some good fiber-fil. I balled up a small bit of black fiber-fil and placed it in the tweeter output hole just for any possible "beaming" problems. Just a bit. If you're a purist, bevel the inside of the woofer holes, as is usually done with the more higher end loudspeakers. It's also never a bad idea to re-cap any speaker. Simple and cheap, too.
