| Re: Single or Pair of 'X' for HT use?
4.4 cu ft is medium sized or some would even say small. Remember this is not car audio. HT requires much larger enclosures and deeper tuning for vented boxes than car audio, where you get a ton of cabin gain and you only listen to music which rarely has bass lower than 30hz. HT has a lot of bass between 25hz-16hz or even lower. The 2 4" ports would both need to be about 35.5" long to tune that size box to 20hz.
The graph that I'm getting is about 4db down at 24hz and -6db down at 19hz. Looks pretty good to me. It should flatten out quite nicely with a little room gain. Usually you don't want a perfectly flat response because of room gain at the lowest freq's.
