BAD idea. It sounds good for your space problems, but the resonances you'll transfer back and forth will have an adverse affect on your sound. You should put your monitors on killer stands as well as your subs. I hope you realize, with monitor speakers particularly, that your stands are an extension of your speaker. I don't know about the cost of the Tyler monitors, but proportion to your stands (quality wise) is extremely important. I have my monitor speakers on excellent stands and my sub, likewise. I can't help you with your space problem, but I really would hate to see you screw up your sound with that stacking idea. If you're interested in more about stands and resonances you can always email me. I consider stands as I would any other major component. The difference in sound quality, between poor and excellent stands is outstanding.
Using subs as speaker stands ?
I own the tyler ref monitors, I am thinking of buying 2 tyler taylo base moduals, I am cramped for space,would it work if I placed the monitors directly on ths subs using rubber isolation pads between the monitor and the sub, has anyone tried this ? thanks all
