THTLP parts list (electronics)

#1 Post by DaveMacKay » Fri Sep 10, 2021 11:21 am

I've gone through the plans for the THTLP. The plans do an extraordinary job in telling one how to build the subwoofer cabinet. However, I did not see a list of the electronic components that will be needed to populate the cabinet. That's understandable since different people will choose different components.

I'm located in Canada. I can find all that's needed to construct the cabinet locally, but I'm struggling to find Canadian suppliers for the electronic components. I may have to order from a US supplier (likely Parts Express) to get some items. I'd like to put together a complete parts list so that I can order everything at one time in order to reduce shipping, customs, and brokerage fees.

From what I can tell I will need the following:
  • 1 x 15" subwoofer driver (preferably Dayton RSS390 HF-4 or Dayton UM15-22)
  • Approx. 5’ of gasket tape for subwoofer
  • 1 x wire jack/binding post
  • Approx. 10’ of 14 (or 12AWG or 16 AWG) speaker wire (copper, not CCA)
  • 1 x min. 200 watt amplifer (e.g., BASH300 + enclosure)
What else will I need?

It would be an enormous help if I could get a complete and up-to-date parts list, ideally with part numbers. I'm also interested in what parts (e.g., amplifiers, drivers) you'd recommend or suggest be avoided.

Thanks in advance,

Some speaker cab terminal options;

Sources for tape. 1/8" is plenty thick. If it gets thicker, the access panel might sit a little proud (one could intentionally set the flanges in a slight bit deeper to compensate). Tape has to be closed-cell. 1/2" width is the minimum. I've found it at CTC and HH. ... 10&sr=8-27

Any two conductor cord will do, even lamp cord (if heavy enough), or even extention cord. ... p.html#srp ... oll-339512
