The serial number has an S in it, which is the date code for 1978. Cornwall II started production in 1985. And it says CD-BR on the tag, which to my knowledge means Cornwall Decorator (Birch Raw)... And I didn't think those came with grilles.

Braking and cornering in F1 is definitely what puts them above all other motorsports... from high speeds they're capable of 5g's deceleration during braking (slowing by 100mph in less than 100 feet) and can sustain over 4g's during cornering. And by 100 mph they generate enough downforce to be driven upside down. Current F1 cars are capable of 0 to 100mph to 0 in less than 5 seconds. I've got the Haas special on the DVR... haven't watched it yet. They are amazing machines.To give a perspective how fast an F1 car can turn. A MotoGP bike (4 million dollars) will accelerate from 0-100 in 4 seconds, they go from 100-160 in 4 seconds. Top speed around 228. They race on quite a few of the same tracks an F1 car races on. The F1 car will turn a lap 22 seconds quicker. I've seen both MotoGP and Formula 1 at COTA in Austin... the current lap records are 1:39.347 for F1 and 2:02.135 for MotoGP. Funny thing is the MotoGP bikes were about 5 mph faster down the long back straight. Both are a sight to see and hear. I haven't heard the new turbo V-6's in person, but like many others they sound horrible on TV. Back to MotoGP... The original 990 cc MotoGP specs (first enacted in 2002) allowed the 2006 V-5 Honda to reportedly develop 285 rwhp (over 300 hp at the crank). Current bikes are down a bit since they're limited to 4 cylinders, but the electronics are much more advanced.

If you're ever in the Dallas area and want to see the birthplace of the Outlaws... Some great dirt track racing out there. http://www.devilsbowl.com/

I used a McIntosh 7270 (270 wpc) to drive my Chorus II's for a long time... Sounded great and I never had any worries when I turned it UP.

Big F1 fan... I've been lucky to see F1 races in Indy and in its return to COTA in Austin and have been watching since the mid 80's. Loved watching Indy Car as a kid (AJ Foyt era 70's-80's), but I don't follow it at all anymore. Indianapolis Motor Speedway definitely has that nostalgic feel to it, but the Circuit Of The Americas in Austin puts it to shame as far as racing facilities go. And there are many places at COTA where you are very close to the track. MotoGP was also great fun to watch in Austin. And nothing against the city of Indianapolis, but the city of Austin wins that battle every time. And I agree about the sounds of Top Fuel and the old V-10's... Nothing like it in person. I'm also a big fan of the NHRA and have been attending races at the Texas Motorplex since before Eddie Hill went 4.99. I hope HAAS has a good showing this year and scores some points. And as a fan of Alonso, I hope he has a much improved car to drive this year. Looking forward to watching the race this weekend.

Bought my first pair (Forte) at 23 in 1989... So that works out to 54% and counting.

There wasn't an "all" option and it kind of changes anyway... So I didn't vote. Couple of my local favorites... "Blood & Honey" from Revolver Brewing: http://revolverbrewing.com/pages/beers And "Velvet Hammer" from Peticolas: http://www.peticolasbrewing.com/beer/velvet-hammer

1989 Walnut Oiled Forte's... Purchased from Hillcrest High Fidelity in Dallas.

I've been complaining about the lack of "specs" on the new website for a long while. And I always get the same answer from Chad... He's busy, has a lot to do and will (at some undetermined point in the future) get to it. Someone posted this link awhile back and it seems to have everything related to the older, discontinued models... https://web.archive.org/web/20120121104208/http://www.klipsch.com/discontinued-speakers

The bass is really about the same between the Forte and Forte II and digs down solidly into the low 30Hz range. The Forte II is rated slightly more sensitive (99dB vs 98 dB @ 1 watt/meter), but seems more so in actual listening (from my long ago memories). The biggest difference is the Tractrix midrange horn on the Forte II... It was really apparent (and an improvement) with a better,"smoother" sound stage and imaging compared to the original Forte. I've only heard CF-3's a few times and never directly against either Forte model (owned both). But I'd say the bass on the CF-3 had more "snap" and was a bit more dynamic. I don't know that either Forte model is "in your face"... But the CF-3 is a little more laid back, until you start putting some power through it.

Having owned Heresy II, Forte II and Chorus II... The Chorus II, from about 40Hz on up, is one of the smoothest and sweetest sounding speakers Klipsch has made. And since it's a bit taller that the Forte II, would provide the best imaging and sound stage. But, it really performs best (in my opinion) with a healthy (at least 100+ wpc) amplifier. The Forte II has a warmer, slightly fuller sound since it plays down into the 30Hz range. And if you're talking just classical music, with a 30 wpc tube amp, it would probably be the best choice of the three. And unless you're just listening at background levels, the Heresy II would need a sub to sufficiently fill in the lowest octaves (below 50Hz). It would also need to be up off the floor to compete (imaging wise) with the Forte and Chorus. Of course, every room, setup and pair of ears will have a lot to do with the decision...

The RC7, RB75 and RF7 all share a 1.75" compression driver attached to an 8" square, 90x60 Tractrix horn... Is that driver "exactly" the same in all three speakers??? I don't know. The RC7 is crossed at 1950 Hz, RB75 at 2000 Hz and RF-7 at 2200 Hz (according to Klipsch data sheets)

The ones in the corners appear to be wider? Are those La Scala II? It's just the position/perspective of the camera... All are LaScala I.

Room is 20' wide, 14' deep with 10' ceilings... LaScalas are on the long wall. No current room treatments, but it could use some to deal with the high frequency slap echo.

I'd stay away from any "vintage" electronics until you can figure out what is going on... Have you checked to make sure all the woofers are okay? Do they move back and forth freely with no issues and no voice coil rubs? Have you checked them with a multimeter? Did you double check the Tweeters before you reinstalled them? If it was just the tweeter diaphragms, then replacing them with new ones would make an obvious difference. It's possible, if the amp has electrical issues, that you could have damaged the crossovers and/or woofers. And if you're going to check/replace the crossovers, then I'd let Crites do the work. That way you'll know it's correct.

I'll qualify my statement just a bit... My issues are with the current 2-way lineup going back to the last of the mainstream 3-way designs (KLF series)... except for the Heritage 3-ways (I own LaScalas). Of the current 2-way models, I don't really care for them. Though the RF-7's, which I've only ever heard very briefly, did sound pretty good. And I agree with Moray about the Epic CF... I love the way they sound. I own a pair of CF-1, and I'm still trying to find a pair of CF-3 or CF-4 to pick up. And though I've never heard them, I'd buy a pair of RB-75 on reputation alone.

Just my opinion... Get the RP-280's if you want (or if the wife demands) but keep the Quartets. For me, I wouldn't trade an updated Quartet for any of the newer 2-way RP series unless they were giving them away. I think the biggest issue/problem with all of the 2-way designs is you have a crossover point right in the middle of the midrange. For the RP-280 that's 1750 Hz. By comparison, the 1.5" midrange in the Quartet covers 650Hz-7000Hz. And who cares what the break up node point is for the 10" Quartet woofer... It doesn't have to operate at 1750 Hz. And I bet, from a dynamics point of view, the 1.5" compression driver in Quartet does a better job at 1500 Hz than the two 8" woofers in the RP-280. Now the Quartet doesn't play quite as low (38Hz vs 32Hz) or have the same power handling (100/500 vs 150/600). But if you're running a subwoofer, then it probably doesn't matter. And at the very upper end of the SPL output capability, the RP-280 may have a dB or two on the Quartet (rated at 117 dB max). Who listens that loud that often? In the end the only thing that matters is what you prefer, in your room, with your ears... But keep the Quartets regardless.
