I promised Rimmer some pictures of my upgraded PC-55 that I got in a trade from Freddie. For those who didn't already know, Freddie had previously upgraded the woofers and tweeters with a really nice set from Sony.
Well, I purchased some Diamond Audio D151 component speakers to upgrade another box only to find out that the DA's wouldn't fit. After finding out the DA's would fit the PC-55, I started the second upgrade.
During the transition, I modified some things.
Instead of using the crappy, hair-width, 20 gauge wire that was included with the DA woofers, I upgraded to 16 gauge, copper extension cord. I also upgraded the wire from the speaker input jack to the crossover. The DA tweeters were already wired with 20 gauge and the housing prevented me from upgrading them.
Once the crossovers were placed and secured inside the cabinet, I added a little bit of fiber fill that I bought at Wal-Mart. I then put everything back together. The DA woofers are about 1mm taller than the Sonys so I had to apply some downward pressure on the cabinet face to screw back on. I also used 16 gauge wire from the amp to the speakers.
The sound is definitely more transparent and the sound stage / stereo separation is noticeably better. The cones on the DA woofers are only 10cm, but they can definitely recreate some nice low punch even though the specs would make you think otherwise.
All in all, It was worth my time and effort to upgrade the PC-55. I might still put some sort of sealant around the speaker cabinet in the groove between the face and body. The hole where the port is allows some air to escape.
Specs for the Diamond Audio D151 speakers:
* 5.25" mid-woofer with spun graphite polymer cone and butyl rubber surround
* 1" titanium tweeter
* 100 watts RMS
* 200 watts MAX
* 4 ohms
* 95dB sensitivity
* 65-20kHz frequency response
* sonically tuned passive crossover with 4.2kHz crossover point

I didn't take any pictures of the process. However, I will have to open the left cabinet again because I forgot to hot glue the tweeter ball. So, I'll get some pics then. 
Ira is driving a hard bargain.
