In my opinion, spending about $500 on a $100 speaker to improve it is just too cost-prohibitive. I’d much rather buy a set of used $500-$600 speakers that when I need to sell them, I can get my money back. When you try to sell a set of those highly-modified Sony’s, what is someone willing to pay? $200, maybe, if you’re lucky? $150 realistically? No thanks.
And while I'm asking, has anyone modified Sony ss-cs5 speakers with a GR Research kit?
I've seen these rather pedestrian looking speakers reviewed by countless YouTubers. GR claims to be able to turn them into great speakers. I just looked on the GR website and see that the kit costs $480.00, plus shipping and tax, not to mention the work involved in building them, making it a rather expensive proposition for a speaker that I can by on CL for sixty-five bucks, doesn't have much more than 85dB peaks and bass that takes a dive at 90hz. The kit for the ATC 19's costs less but I guess the Sony's really need a lot of parts.
