I have one (soon to be two) THTLP subwoofers accompanying my Klipsch La Scala speakers. Because of its size, the THTLP attracts a lot of attention. Most of my friends, upon seeing the THTLP, want to know why I felt something so big was needed and what it would compare to. That sets me off on a talk about how a horn is different from a direct radiator. I talk about air displacement and use Bill's analogy of paddling with a pool cue versus a paddle.
Eyes glaze over. Women cluster around my wife to offer support.
I've mentioned that, according to the THT web page (https://billfitzmaurice.info/THT.html), comparable speakers would cost around US$2500 (roughly CAD$3200). That seldom impresses when I tell them that the THTLP cost about CAD$2000 even though I built it myself.
I'm then asked what would provide equivalent/comparable performance to my THTLP (which has a 12" driver). Essentially, they are interested in knowing what a comparable commercially available subwoofer would be in terms of:
- size and number of drivers
- ported or sealed
- cost
What sort of simple answer could I give folks who are curious, but not really conversant in audio?
