I have Tannoy PBM6.5 monitors on 12" stands on 10" subs in my HT system and it seems to be fine. You loose the flexibility of optimally positioning the subs in the room but I'm quite happy with the sound.

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.
As Danner suggests, the ideal sub locations will likely be very different than your ideal speaker locations. As Warrenh suggests, stacking will not provide the same sound as separate stands (the bass will transfer through the rubber and the height is not ideal). For space saving purposes, you might choose to get the stands and place the subwoofers behind them. There is no direct transfer of bass waves and the subwoofers would be closer to the rear walls (where they generally sound better, but every subwoofer needs to be placed a bit differently). Good luck.
Component quality speaker stands exist! Rubber will only slow and then re-release stored resonant energy back into your speakers, your room, and again your speakers, and then your room again . This continuim does not stop. I would first optimise your main speaker setup and position and then when this is complete move on to subs. Subs also need platforms that will allow for the high speed transfer of stored resonant energy. You are also welcome to e-mail me. Good luck. Tom
As stated, good stands are going to work better than stacking on the subs. But if you want to try it, look into a product called Microsorb, sold by percyaudio.com. It is a sticky acrylic damping sheet that will not only hold the speakers very effectively, but will also absorb a lot of excess cabinet vibrations.
You might want to think about the Ref II. It is basically the monitor with its own passive subwoofer section. This will give a better appearence. I am sure Ty could make you a bass module for the ref monitor (Lynbrook style). I am not a big fan of powered subs when used with high quality monitors. Getting them to sound just right is time consuming and frustrating. It might be the cheap crossovers they use in the sub amps. Some of my taste in music contains a lot of bass. For me passive is the only way to go.
thanks for all responses, but the responses leed to another question, since some replies sugest that putting monitor on top of subs causes distortion in the sound waves,what about the aerial 10 t where the top modual sits directly on the base modual, also the tyler reference speaker does the same thing and I am sure there are others, if its true that sitting the top peice directly on top the sub section causes distorted sound waves, how do the above mentioned speakers overcome it, thanks all
Without doing the in-depth research on the specific models you mention, the bass units I've usually seen attached to the midrange/tweeter sections are 1) not independently powered (i.e., they are passive units) and 2) specially designed and braced to accommodate the match-up. One unit I have heard that had a powered sub-woofer in the same cabinet as the midrange/tweeter was the Definitive Technology speaker and it was overkill on the low end and dipping rather dramatically in the lower midrange/upper bass region. Was that a design problem? Don't know. I've heard many good things about similarly designed Infinity systems.
Place your hand on top of a sub-woofer and you can feel the vibrations. Place your hand on the cabinet of a speaker cabinet and you would not normally feel the vibrations. There are different design parameters that need to be used under the different design objectives. Stand-alone subwoofers are not designed to be physically connected to other speakers. If they were, they would likely require more space and more bracing in order to reduce the cabinet vibrations.
That's my top-of-mind response. I welcome corrections and expansions of the explanation. Good question. To expand on the question, are there speaker companies that attempt to physically isolate all of the independent speaker units? My experience has been that isolation and stability helps greatly (e.g., speaker cones or stands). I wonder if any company took it further?
Ozlfy is dead on. This stacking idea is not the way to go. I think you have some good information in these threads to make a decision. You may have to make more changes than you thought. The stacking idea, however, goes agaisnt resonance principles and the like. If you really want more technical data, email Audiopoints.com and ask for Robert. He will set you free.
