Hutz, I have some views on the comparo though I must preface that while I have extensive experience with the EP subs I have yet to hear the 350v3. I'm currently cooling my heels at LaGuardia in NYC so I will respond later. In the meantime it would be good if the OP provided more detail about his listening preferences, size of room, etc. Suffice it to say that its no contest that the EP500 surpasses one 350v3 in all areas but a pair can be formidable depending on how you want to configure them.
