These are nice looking and nice sounding speakers.
They can not compete with my Polk SRS2's and I didn't expect that kind of performance. I was surprised with their performance. The sound stage is good, the midrange is tight, real tight, but lack the low end which is to be expected vs the SRS2's. Since I can not leave well enough alone I pulled a x-over and didn't see much which you'll see in the pictures.
I Decided to call our friends at Sonic Craft and ordered the following:
4) 4.7uF Sonicaps @ $11.70 ea. = $46.80
2) 1 ohm 12 watt resistors @ $3.85 ea = $7.70
$54.50 total for the parts. I ordered other stuff so am not including freight which was $8.95, a rip off but who cares
It took me less than an hour to remove then re-install the two caps and resistor in each x-over then re-install everything. With a little fitting the caps fit nicely. I had to extend one of the leads in each cap with the lead I trimmed from the other side of the cap since I stood them on end. A little hot melt adhesive and I was all set. Later I will hook them up to the Cambridge Audio integrated amplifier and Arcam CD72 CDP and let them "time adjust" for a few hundred hours. I think time adjust sounds nicer than burn-in.
I did speak with a couple people at PSB about this modification. For Canadians they are great, just joking, and they told me they don't suggest it.
Of course I am not worrying about any warranty because if I have a problem I'll hold Doro responsible
Paul Barton is a great designer and manufactures great speakers. Similar to Polk Audio they do whats right for the market place and use price sensitive components in the x-overs. For what its worth a replacement x-over from them is about $35.00 each.
Next week I will put them back into play and see/hear what I did.
Oh yeah, Check out that little tweeter!!!
