How can I bring the F1 up to S4 height?

I bought a flight case for this purpose, because it allows me to have an S4 and 2 F1's at level and it looks frikken awesome. Unfortunately, it is unwieldy and only suitable to DJ booths that permit a certain amount of room, which is very few. The alternative is making your own wood/foam blocks to sit it on. It's a niche in the market you could make a couple of quid on actually.

Thanks for all the input. I don't really want a flight case because they are so bulky and would ruin the inside of my car. It looks like the bag may be the way to go.
