You'll find that the PC-8 is a completely different machine - the PC-8 is bigger and more powerful. The PC-9 is one speaker cabinet narrower than the PC-8.Ghettoboom767 said:
I haven't heard a PC-9 though so can't give a valid comparison with regards to sound quality.
The PC-9 sure is a looker!

I have had a bi-amped, x-bass Panny myself that I got in a trade from Norm. Selling it was a major mistake, right up there with selling my first M-70.

Thanks for that info,I just missed out on a PC-8 for 45.00! Bad speakers though but I should have got it.jimmyjimmy19702010 said:You'll find that the PC-8 is a completely different machine - the PC-8 is bigger and more powerful. The PC-9 is one speaker cabinet narrower than the PC-8.

I feel the PC-9 is practically a Hi-Fi with very clean powerful sound,yes there needs to be a real test against these 2!😋😎😮🎼💳📟
Here is a tip for current or prospective PC-8 owners with a unit with bad drivers - RX-DT680s speakers are a possible replacement. You will have to modify (bend) the outer lip to flatten it out for the screws to attach though. The soft, compliant surrounds of the 680 speakers is very similar to the original PC-8 drivers.Ghettoboom767 said:

I own a pc8 ,pc9 (Sanyo version ) two pc55 two or three 680s
I don't think a pc8 is even as nice sounding as a pc9.
The build of the 680 isn't really great .
I kinda think that the pc55 fh7 are really in a elitist category. For a long time I used a pc55 with a external sub as my main listening station .
The big Panny cobra top egg has killer sound that runs with the 55 and fh7.
I do like my pc8 it's a really big nasty device but I see little point in using it much because it doesn't sound anywhere near as detailed as some of the other units I have. The Soundstage is warm beefy but, it's just not my favorite.
The pc9 is a pretty prolific aka box . I think vector yamaha and Sanyo are three that quickly pop to mind . It's a good box sounds a lot like a quintet that is in its own right very nice .
for all the boxes I still have (yes I've given away approx 50 blasters ) the ones I think sound the best are sony fh7 pc55 sony fh215r panasonic dt707 yeah this one sounds really really good. I've owned lots of the platinum panasonic dt series . 680 is very nice but,it's not made to last . My cobra top still works like new . All my 680s have some kind of fault

I think it depends on the electrical condition of the actual box you're listening to. My PC-8 blows away all of the 680s I've heard (I've got two healthy 680s here right now to compare to). The 680 gets close but no cigar. IMHO).
I agree that the 680 feels like a lightweight in terms of build when compared with the beasty PC-8.

The build of the 680 does seem like crap in general. I'm not a big fan of the sound of the 680 it's probably why I've given so many away .

Thanks Bill for your input,I have all except the PC-8.
Love my PC-55's! 😋
My PC-9 is very clean and had incredible bass for its size.
I'll stick with the PC-9 for Yamaha,wonder if they ever made a 1 piece? Don't think so,quality units though.

Because the 2.7-8 ohm terminals connect to an amp that is connected to a 2.8ohm speaker (driver). The other terminals (8-16 ohm) are connected to an amp that's connected to 8 ohm tweeters so it can handle a minimum of 8 ohms or more.panabox1 said:
That's a pretty wide range. So then replacing the woofer with a lower ohm (say) 2.7 won't overpower the amp while at the same timean 8ohm woofer won't be under powered? All from the same amp?jimmyjimmy19702010 said:
The lower the ohms, the lower the resistance. The number you are interested in is the minimum ohms an amp can safely handle. So in other words, the lower the ohms, the more power the amp is asked to produce. As you would know, the 680 has 4 amps (2 per channel). The 2.7 ohm drivers are connected to a pair of amps that are designed to cope with these drivers. Going higher ohms with your speakers will just result in the amp producing less power.
The tweeter amps that are designed to cope with a minimum of 8 ohms would be damaged with a 2.7 ohm load.
