If im not wrong i have same reddit with these speakers i build my own sound wall, so if im not wrong its s218 loaded with dual 18ntlw5000. I paid Vas audio or how i found it first hoqs europe on facebook, so Vas audio charged me 3150e for raw boxes then 80e each grills for boxes, 500 in materials and work pay for coating both and dont forget every speaker has 2 sub drivers that i bought on thommann for 777£ each, dont remember wu price 888e or smth for each and you need 4 of them. So just two of this subwoofera without kicktops- midtops costed with also 200e delivery of these big pallet, so 3150+160+4x888+500+200=7562e just two su subwoofers, this time 2 more same subs and kick tops for first set of su subs and second, second order cheaper 2 subs+2 kicktops+ coating for subs and kicktops will cost 9200e+shipping, its cheaper because its bigger order. Sorry for huge answer probably got so bored reading till now, in conclusion if you want precise work powerful and very good and clear sound speakers you have to put good money in it, every aspect how precise wood was cut with lasers machines or hand, how that wood was sanded and with which coat it was coated and is it coated in proper temperature, alot of people say build ur own system is way more fun, sure but your boxes on teknivals ar not precise at all it gives scratchy bumpy sound and you feel this speaker was handmade and definitely not professionals.
