Alan, I've never seen a slit like yours used as a bass port of sorts. Can you explain the advantages/disadvantages of having a slit vs standard oval ports for bass reproduction? Is it better SPL, distortion, frequency extension or something else?

They are pretty common for transmission line style of folded ports.

I wouldnt say they are common, but they are certainly about. Ports dont have to be round. They just need to be able to flow the requisite mass and velocity of air without undue turbulence, and of course be tuned to the correct frequency. There is no particular advantage to slot ports, however in our designs they work very well in terms of placement and cabinet construction.

Also we have configured them so that they dont leak frequencies outside of their range like many designs do.

So, maybe with a taller slot, can you can further extend the lower frequency response from Graph 1 to be flat down to 20Hz or below? Does graph 1 include room gain?

This speaker only has 1 woofer but the Sointuva bookshelf has 3 for almost similar frequency response. With added room gain, these frequency responses should be almost identical. Is this a fair assessment?
