Ported versus sealed speakers: is one type better?

^ If you had ever read any technical papers, you would know the answer to that question, it’s in the literature. Too much trouble to do the work, it’s easier just to display your ignorance and laziness? If you find reading too demanding, can you at least watch videos? Danny Richie has a series of GR Research Tech Talk Tuesday videos on YouTube in which he discusses in detail loudspeaker and subwoofer design.

Transmission line is best when properly implemented.

In my experience and to my ears sealed enclosures are better than bass reflex.  Transmission lines are better yet, but horn loading is best of all.

Speaker designs are tradeoffs. Ported designs can go deeper and play louder, in general, while sealed designs have superior definition and textures.

Ported designs do NOT "go" deeper than do sealed. In fact, the exact opposite is true. Ported woofers provide more output down to resonance than do sealed designs (which are already rolling off at 6dB/octave at their resonant frequency), below which they roll off much faster (12dB/octave) than do sealed. The same driver in a sealed enclosure will play lower in frequency than will the same driver in a ported one, but with lower output above resonance. That's why sealed are recommended for smaller rooms: with the gain provided by that room, a sealed woofer's output will match that of a ported, and will play to a lower frequency. And with, some feel, better sound quality. Rythmik's Peter Ding recommends his sealed models for music reproduction.
