Heavy speakers: How to be able to reposition?

One of my systems uses Wilson Maxx 2s which weigh over 400 lbs. each. The speaker bases are threaded for spikes, but the threading also takes heavy duty commercial casters which helped set up a lot - and while you could (somehow) jack them straight up and swap to spikes, I decided to just lock the casters in place and I doubt whether spiking would improve sound anyway.

FWIW, these speakers are set up with vernier adjustment of the rake angle of the top module (tweeter and two mids) and we set them up using a laser range finder with me sitting in the listening seat, and I have had zero urge to move them (although I did apply markers with carpet tape in case I ever did want to mess about with them.

Hi @musicfan2349 - I just came across your post and was thinking, if you hadn’t yet got those sliders, and your listening space is planned to be hard-floored, that you could use the placement plinths I designed for my 85kg apiece speakers. They work really well for fine tuning speaker placement. In the case of your bw matrix, they would be jacked from the front and rear, with the plinths slid in from the side for greater stability, seeing your speakers are deeper than they are wide : ) You can see these at -

I don’t buy speakers that my wife can’t lift. 

Perhaps @rocray has the best response.  I cannot tell you what to do, but do share 25+ years of radiology, shooting x-rays on patients with spine damage and post surgery, provides revenue stream for everyone:  PT, surgery, radiology, orthopedic, lab, nursing, etc.  

Most spine damage is permanent and not correctable regardless of what the super surgeon tells you.  It usually leads to slow decline and affects other parts of the body as misalignment of one part skews load on others.  It's usually a one-way track. 

Carefully consider your actions.  We in medicine call it job security.  Be well.

+1 Excellent advice, which to me says, use your brain not your back. If you use your brain there is always a way to move any heavy objects without damaging your back.
