Tjenare!

Jag har 4 st 18ND930.
Förslag på små lådor önskas.
Dom behöver inte gå under 40Hz.
Det är trycket jag är ute efter

Hytten är ca 4m2 så urymmet är begränsat
för tillfället

Tjenare!

PP;dom lådorna är vikta för 15W1300

Jag funderar lite på att sätta dom i väggen å bygga lådorna
i hytten brevid så det blir Wall of 18

Tryck har jag nu men mycket vill ha mer å Lab SS1000 gillar 4Ohm.
Det är ju trots allt bara en sovrumsstereo.

Skulle passa bra i de BR-lådor du iallafall skulle köpa av mig. 150-170 liter, 400 cm2 port ~30 cm lång.

Hur skulle du inte kunna få tryck på 4m2 med fyra artontummare?
