i like a project where I can take a low-end, modest ( cheap ) speaker and turn it into a giant killer!
and it appeals to my altruistic proletariat motives as many people in MANY countries are stuck w/ their low-end gear yet w/ some tweaks and fine tuning & crossover mods we can make things MUCH better!
thern i like finding new application like turning a tower speaker into a better Center channel speaker than the supplied W/T/W
|and i like working w/ an expert to do this !
oK FOLKS HERE HOW THEY CAN BE FIXED !the sony tower Sony SS-CS3 3
Danny, GR research said : " We’ve done that upgrade on the Sony tower Sony SS-CS3 3 and look forward to getting it back to you. "
here are the results AFTER it’s fixed !
the sony tower Sony SS-CS3 3
Impedance: Fairly balanced other than the dip in the lower midrange down, to 2.67ohms in the lower midrange.
the sony tower Sony SS-CS3 3
Spectral Decay: Much cleaner decay overall, but still a bit messy, should clean up with NoRez and some additional stuffing
the sony tower Sony SS-CS3 3
Vertical Axis: they get a fairly proud around 3Khz as you move up above the tweeter, but still fairly smooth overall.
the sony tower Sony SS-CS3 3
Horizontal Axis: still very smooth.

read and weep
"We did Design something for the SSCS3 that worked out pretty well, but the main issue is that the impedance unfortunately drops to ~2.7 ohms at ~350Hz, which will make them quite hard to drive, and can make some amps run hot or cause them to become unstable.
Here are the new measurements: (old measurements in the attachments)
OnAxis+ crossover: Much smoother response than stock."
thousands of happy customers in 105 countries rather well proves the wisdom and efficacy of GR research approach!
his critics are facile proven idiots , dolts IME ! Danny knows what will sound best and simply ..............................does it !
he recently corrected this low-end Sony tower speaker and will soon correct the crossover when i send the same speaker back to him now redesigned by me as a horiziontal center channel speaker w/ the base removed & w/ the drivers re-arranged.in a W-t/M-W configuration !
the point is to take modest-priced speaker and make it as good sounding as an expensive one !
he did the same / similar w/ the bookshelf speaker of the series brilliantly making the super-tweeter the tweeter and the tweeter a dome style midrange ! his crossover magic ! all w/ out changing the drivers!
this resulted in a very cheap speaker $180 a pair ! having the performance of $1K speaker ! amazing !
next crazy project (and a bit more difficult is to take one of the Sony SS-CS3 3 towers take off the little base and turn it horizontal and make it a upgraded center channel! we will reconfigure the speakers to a ideal center channel W-T/M -W configuration! 
yes it will require new faceplate and new x -over too!
we are considering configuring the woofers w/ the Allison acoustic push pull configuration ! that means they are electrically OUT of phase but acoustically IN Phase . it gives 20% less harmonic distortion too! here is the little stock center-channel
one has to wonder if it is that the makers are doing such p$%-poor engineering, design or that they deliberately use such cheap a#$ parts!?
as a member of SAE ( Society OF Automotive Engineers ) I know if automakers did this, used cheap parts, cars would be nearly useless!
