If the bottom can be made out of MDF then that would be a good route to go. In fact any side that can be should be IMO. It won't do anything to the sound. It just makes the build faster and easier. it will also be a little cheaper, because fiberglassing cost good money.

I stated that as well. To my knowledge as long as the proper precautions and procedures for either method are taken, then no difference should be audible in sound.

large flat areas are stronger when made with wood versus glass, its eaiser to do, but you will hear any difference if it is properly done.

if the guy is making it for you - why should he be asking you how to make the enclosure? i would be kinda iffy if he asked me... he should know what he is doing.

its not that he was assking me how to do it, he wanted to know which one i wanted, so im asking u guys to tell me whihc would be my best decision

I would go ahead and do MDF, might not sound different but it is stronger.

Use MDF if airspace is not an issue. If you need all the volume necessary, use fiberglass. Sound quality will not be an issue. You will not have a lot of flex if built properly and the fiberglass panel is supported by the floor any ways.
