Great thread.  I'm all about the base.

Nice to know some of my old schoolfunk was demoed on the KP600's.  I would love to hear em'.

I love the sound of dual 18" woofer reflex bins that are tuned 35-45Hz.  Very common rigs in disco clubs back in the day.  No they aren't horn loaded but handle the space bass nicely. 

 If I remember correctly, the KP600 dual 18" woofer bins were tuned somewhere around 40Hz.  The ports are nothing but 3/4" circle cutouts.  This is much different than the modern day KPT-684's used for Klipsch theater stuff.  The port on those are much longer and I think tuned to 28Hz...with a -dB slope after about 40Hz (something like that).

I too love the sound of horn loaded bass but there are few that reach the bottom end well w/o a sub.  I've heard the MWM's in corners and love the way they sound.

I now own 6 pairs of the double stacked MWM bins (12 woofers worth).  In time I hope to stack them in corners to achieve an even lower response.  Who knows.....even after doing that.....may have to add a sub

JC,

Glad you found the thread!!

I enjoyed that disc, not my number one listening pick, but it was still an excellent recordind to demo with and we listened to it many times!! It was also very good to Demo Kevins Jubilees both with and without his KP-684 sub turned on, but much prefered the sub on. As I stated, we listened on alot of different occassions to it.

I have the KP-600 literature here handy that Kevin gave me and the KP-600 sub cabinet is called the KP-680-SW and response is 30 to 130Hz, very strong on Funk!!!

JC, please keep me in mind if you ever descide to let loose of any of those MWM bins as I have started collecting MCM stuff as well

 hmmm, now my mind has to go to the - well, why can't we retune the KP680 SW to 28 Hz then? Especially if so many of us are installing the K47EP2 drivers (same as the KPT684 theater sub bin)?

Does the internal box volume come out to about the same?

Michael,

Are you sure the KPT-684s all orriginally came with the K-47EP2?? Kevins KPT-684 is all orriginal,and while he did not pull one of the drivers out of his KPT-684, he did not think it was the same driver as his 4 K-47EP2 drivers he just got and installed in his KP-680-SW cabinettes.

There were 2 different driver orriginally that came in the KP-680-SW cabinettes. The magnet backs on the earlier woofer units were flat, while the later units had a humped up area on the back, these were the improved drivers. Kevin had one of each, and gave one to his brother and the other to Bill H. Bill had both types on his 600s.

The recomendation to buy the K-47EP2 as an upgrade came directly from Roy to Kevin. Bill had talked about ordering the K-47EP2 for his churches stacks, but as far as I know, he is still using all orriginal drivers in his stacks. Myself, I definetly plan on ordering 4 of the K-47EP2s when I get arround to it.

Right now I am planning on selling that single K-Horn I have and buying that RF-7 that was converted into a center channel to replace my moms RC-7 that you saw when you and Indy Roger came by.

I definetley plan to get my 600s in good shape by next year, so how about a story with pictures of the revamping of yours and maybe we can see how many 600s we can get together for your Indy Shin-Dig next year Mang!!    MMMMmmKKK??

So if you get a wall of KP-600s set up, will you be playing Deep Purple and The Who, just to see if you can match their concert volumes?

Islader,

If Cholter and everyone else is game and could make it, it could be very interesting!!

Michael has a set of 600s, Kevin Harmon has a set, Bill Hendricks has a set he got for his church, I have a set. That is 4 sets, or 8 stacks that are capable of 134Db per stack, on top of which, michael has a pair of MCM-1900s, Kevin has Michaels other set of MCM-1900s now, and I am trying to piece together a set.

Could get cops from a couple of different jurisdictions involved with that much SPL on tap!!

It is Michaels show, a long way off, and alot has to fall in place, but it is never too early to plan ahead.

I think it could make for alot of grinns on peoples faces!! I have heard 2 sets of 600s or 4 stacks, and a pair of 450s playing in an outside venue, and it was powerful, real powerful!!

 Klipschorns with a little help from Universal Studios (Sensurround Earthquake).  For bass you can REALLY feel.

Since Klipschorns have a maximum accoustic output of 124 Db, and each KP-600 stack has a maximum accoustic output of 134 Db, that means every KP-600 stack has the equivelent output of more then 8 K-Horns / 1=124, 2=127, 4=130, 8=133 Db

The wall of sound below would be capable of more output then 48 K-Horns!!

Re: Welcome to the Vintage Vault wallofsound6.jpg Reply Favorites Contact 4 kp-600 stacks,  the ones on the outside are for Roger Gordon,  the mcm stacks and inside 600's are mine. Kevin     There is another KP-600  Stack clear to the right that is cut off in this picture. If you HIT THE REPLY BUTTON AT THE TOP OF MY 3:44 AM POST, the picture opens up and shows the last stack, so you can use Kevins 1972 Blue 442, the Red Convertible Chevelle, and the boat behind the Chevelle in the shot to approximate the size of these speakers. I am 6'3" tall and each KP-600 stack is about 3 inches taller then me as shown. If my two KP-600 stacks had there 18" drivers, there would be 8-18" drivers, 12-15" drivers, 6-10" drivers, 6-KP-600 mid range horn drivers (mine have the double driver settup & Kevins have the single), 8-K-77 tweeter drivers and 10 Piezos in this photograph.                                              Roger

And to think that you could probably power all those speakers with a few of the little Trends 10-watt amps.  That could be a heck of an ad!
