My PC desk is almost against the wall, with my LSR-305's 8" - 9" from said wall and now resting on a 4" x 6" x 9" hard foam 'brick', sold by Amazon as a black 'yoga blocks' @ $10.79/pr, inc Prime s/h and s/t. The sounding board bass enhancement and bass resonance were killed by the blocks. In fact, it's like I added a bit of bass extension, too - now even with the LF "tilt' down 3 dB at flat. Great PC speakers on, er, 4" above, the desk. I can't compare them to the 230's or RP-160's - but I can compare them with my NHT SuperOne 2.1's... sort of!
I now have my S1 2.1's, located at ear height on my corner bookshelves, driven by my 50 Wpc Emotiva A-100 BasX fed by my C-7030 CDP. I have my recent purchase MP-301 MK3 SET amp daisy-chained through the Emo amp's Line Outputs and it drives my Heresys - below the NHT's (On the floor!). Of course the Heresys sound the best... even though the 305's have better bass extension than either the NHT's or the Heresys, which, oddly enough, sound the same bass-wise. It must be the crossovers... how else could a 6.5" LF driver - in a small sealed enclosure - have the same bass response as a 12" in a larger enclosure? Of course... the SPL's tell that story... 86 dB vs 96+ dB! The 305's do sound good for the price paid!
