I used this customization:

(custom-set-variables
'(display-buffer-base-action
  '((display-buffer-reuse-window display-buffer-pop-up-frame)
    (reusable-frames . 0)))
'(display-buffer-alist
  '((".*" . (nil (inhibit-same-window . t)))))
'(switch-to-buffer-obey-display-actions t))

to get new frames for any type of file, and then Speedbar popped up with a 
layout according to defaults-frame-alist; by “layout” I mean frame geometry, 
font, color etc.
