[Tex/LaTex] scrlttr2: How to remove the white space between “address” and “Subject:” line

koma-scriptlettersspacing

How may I remove excessive white space at the top, between my address in top-left, and the Subject: line?

\documentclass{scrlttr2}
\usepackage[english]{babel}
\usepackage{graphicx}
\KOMAoptions{fromalign=left, fromlogo=false, addrfield=false, backaddress=false, subject=titled}

\setkomavar{fromname}{My Name blah}
\setkomavar{signature}{blah blah}
\setkomavar{fromaddress}{blah blah\\blah blah}
\setkomavar{fromemail}{blah@blah}
\setkomavar{fromphone}{123456789}
\setkomavar{subject}{Reference: blah blah}

\begin{document}
\begin{letter}{asde\\werd\\wesd}
\opening{Dear Adam,}
blah blah
\closing{Yours Sincerely\\ \mbox{}}
\end{letter}
\end{document}

Best Answer

You could adjust the pseudo-length refvpos to make the space before the subject line smaller. refvpos determines the vertical distance of the reference fields line from the top paper edge.

For example:

\makeatletter
\@setplength{refvpos}{5cm}
\makeatother
