I am new to the Home theater stuff, so bare with me. I just bought a bunch of the JBL ES series speakers for my first real home theater setup to be powered by my equally new Pioneer VSX-1018AH-k reciever. So far everything sounds clear except I don't seem to be getting that "punch" from the 8" woofers in the ES-90's. I am moving up from using computer type surround systems such as the Logitech Z-5500 and Klipsch Promedia 5.1 Ultra. In any case the Promedia had two 8" subs in the subwoofer. I have to say that system rocked in terms of "punch" and sound. With that said moving from that to the JBL's I would think I would be rocking with serious bass while listening to just stereo sound, but I'm not. Some reviews I read said the JBL's sounded good without a subwoofer, but I haven't heard it yet. This leads me to the question of whether I need more power "WATTS" to the ES-90's? I am more familiar with car audio, but I imagine it is the same concept, but I am not as familiar with the products in home audio. In car audio when you add more watt's/power with an amp to the sub or any speaker you can see the woofer move, jump around, or whatever and tell a sound difference. So far none of these 8's have moved. They are putting out some bass, but nothing like you would think for listening to just stereo sound. Any thoughts or suggestions on what I may be doing wrong or need to do to get this thing jamming? Thanks in advance.
