Thanks those are nice the BMS I guess can go lower crossed around 1.8kHz? Which 1" horn you're using and 12" driver just curious? Also since you've build one TH-1819 how is it coming along? I may use the Faital 18FH500 will build 4 subs initially, will let you know when I start!

It is 2-way system, mid bass driver is neodymium RCF_MB10N251 from 120 Hz - 3.0 kHz and BMS4540ND from 3.0 kHz - 26 kHz and TH_1819 is just perfect tonal blended in

Nice builds, can I also ask you I happen to download and print the 15mm and 18mm version of the TH1819 plans. I would like to make it lighter by using 15 Marine Ply or Baltic Birch I have not decided which one but looking at the plans there is a measurement between the panels on the bottom spacing between 2 panels is 100mm for the 18 mm version plans. Now the 15mm version plans do not indicate the space would it be 106mm since it is thinner ply (15mm sub) or would it be the same 100mm indicated on the 18mm version and make adjustments for thinner wood??? Thanks!

If you want the lighter and the stronger the best way would be 18mm Marine Ply which is ligter than 15mm BB. 18mm Marine Ply weight is 450kg/m3 (18mm MP for 1m2 weight is 8,1kg) and 15mm BB weight is 720kg/m3 (15mm BB 1m2 weight is 10,8kg) and you need for TH-1819 construction 6m2 (18mm MP total weight is 48,60kg (107,28lbs) vs (15mm BB total weight is 64,80kg (143,05lbs). Yes you need to make adjustments for thinner wood (15mm).

Do you think these tops might be good for PA use? Also, do you have frequency response plots or hornresp models of them?

P.s. stumbled on your youtube video while searching for drivers

Shure are good for PA use with high sensitivity and controled dispersion, they are very flat. I will post new video to youtube in short time with new TH_1819 (just building the second one ). The video will host two of the TH_1819s.
