True. For their price point, The weakness chain of the Klispch 2.1 is the LF. I do not like too much bass even in my hi-end system. If you looking for a tight chess bass in movie track, look for a solid sub like SVS or HSU where the LF response can drop down to 20/25Hz. You will have to pay a lot more than $119.00 when on sale @ BB. Having said that, in my small treated room, I find the Klispch 2.1 is very musical and dynamic. I set my LF knob around 8:30 to 9:00 o'clock the most and the volume control always set around 9o'clock. With that setting, I hear what I like in music be it Classic rock, Blues ... Tight mid bass, warm vocal and airy but not harsh HF. I have the speakers 4 feet apart and the sub woofer right in the middle of the two speakers. Sitting about 3/4 feet away right in the middle and in front of the subwoofer is my sweet spot.
I am a near field and mid field listener so my experience may be completely different than others but I like the Promedia so much for what it worth, I have not touched my big boys. Mackie HR824 MK II, KRK VTX8 G3, KRK RP 8G3, and the overly hyped JBL LSR308 for a few week now. If you want a full blow down to 20/25 Hz, look some where else. For near field listening, if you can balance the LF so it won't smear into the mid frequency, the Promedia is worth every penny of the $119.00.
BTW, I use the Teac Dac in front of the Promedia 2.1 but that won't matter much with the balance one must find with the LF setting to get a coherent overall sound.
My 2 cents.
