[Tex/LaTex] reduce space at the top using maketitle

Question

I'm using XeLaTeX for my document and want to style my title page. The problem is, that \maketitle make a large top space, my text begins ca. 10 cm from the top. How can I reduce this space? In the moment it looks very crimped at the bottom.

Here's the explicit code:

\documentclass[a4paper,12pt,twoside,ngerman]{article}
\parindent0pt
\parskip6pt
\usepackage{fontspec}
\usepackage{lmodern}
\usepackage{microtype}

\setmainfont[Path = fonts/,
    BoldFont = akko-w01-bold.ttf,
    ItalicFont = akko-w01-italic.ttf,
    BoldItalicFont = akko-w01-bold-italic.ttf
 ]{akko-w01-regular.ttf}

\usepackage[ngerman]{babel} % Paket für die neue deutsche Rechtschreibung
\usepackage[...]{hyperref}
...
\title{Title}
\date{}
\author{}
\begin{document}
\input{./acronyms}
\input{./glosaries}
\maketitle
\thispagestyle{empty}
\begin{center}
\textbf{{\large Thesis}}\\

Answer 1

Include the \vspace command in the title command, i.e. change the line

\title{Title}

into

\title{\vspace{-2cm}Title}
