Thanks. The only swearing this time was when I guesstimated the extra space I would need on the back panel for the Tolex, and then it STILL wasn't enough. But it was already wrapped, so there was some coercion to get the panel in.
Ported is tricky as it does open up the bass, but the extra excursion can be more than the speaker was designed for. This can be volume (dB) dependent. Since this cab will only be used in a lower volume home setting, I can get the bass without the risk of flub or blowing the speaker. If I used it with a band, I'd have to really be careful about over excursion. That's where that removable front plate to tune the port can come in handy. Off - allows max excursion, on - tempers that a bit, though I don't get how it's much different from an open-backed cab. There really is a noticeable difference in sound with the plate (which I didn't really think would be the case).
