Erik said: It's probably true, too, that careful measurement would reveal some oddities or other characteristics that might not 'look' so great on paper. However: I have no means to test our room response or sound quality other than my ears, which are of course ultimately what will decide on what sounds good or not so good. In this case, the 'good' brought about by the inclusion of a center channel is to such a degree that I have no intention of ever going back to two channels alone -- regardless of what theory or testing might disclose. What I have discovered is a sound so complete, lifel-like, palpable, etc. that it's almost uncanny! Last week I did an experiment where I turned the center channel off just after my wife left the listening room for a glass of water. When she came back, she looked at me, looked around the room, and said, "Did you do something?" "This sounds bad!" The sound she was referring to was the Klipschorns running by themselves in stereo-only mode. --------------------------- Yes Erik! Good test using the unsuspecting wife!! I do similar things with my girlfriend. I like trying something and then without telling her what I've done or what changes I've noticed in the sound I'll get her observation. Since she doesn't get into this critical mode of listening(which is something that at some point in the experiment I try to turn off and start listening more relaxed(natural)mode like at a real event) its a real help hearing her observations against my own. I believe just like you do that the ear will be the final judge! Even though their might be things that don't look good in a measurement the center channel is providing needed information that without it the sound isn't perceived as natural as when the center is providing this information. I(like you) am always trying things for the personal experience/knowledge that can be gained. Like I said I'll be very interested in your observations with the Lexicon unit. mike

Hi NatGun I have a PWR transformer from a DH200 which I'm pretty sure is the same one the DH220 uses. The Transf. should be in good shape I had it left over after modifying a DH200 to a dual momo pwr supply. # on TRANSF. 464002 and 8318150 I believe the 464002 is the number to go by. The DH220 was basically a refinement of the DH200 circuitry and the amps where basically the same. You can have it for the cost of shipping if you want it just PM me with some contact info. mike

Hi Erik FWIW: One problem I've ran into with wirewound L-pads is over time the wiper contact can vary due to oxidation between the wiper contact and wire which just working the control from end to end will temporarly clear up.Yours look like really good quality and the ones I used where fairly good quality also but once they are set and not used over time the connection tends to oxidize over time since the cleanig action of using the control doesn't happen once a setting has been chosen.Maybe you will have better luck with them than I've had. I like to replace the L-pad with resistors. Once I've settled on the setting I'm going to leave it at. I just take it loose and measure it for the resistor values I'll need to replicate it with. I'm using the ALK crossover with the variable autoformer.Its really an interesting learning experience how just a small variance in the squawker setting will show up different things in the recordings by not just the tonal balance shifts but there is some masking effects that show up or nearly disappear depending on the settings.I've also noticed the same effects by how I use room treatments. The center channel speaker you been experimenting with also is an eye opener about how we hear. If you think about it, by adding the center speaker you are changing things more than a person might would think.You will be changing the first arrival times due to the different locations/designs of the speakers(The lexicon if it has center channel delay will change this to some extent and I will be really interested to see how this changes your perception of the sound). You will have constructive and destructive interaction between the speakers.The speaker room interaction changes also.What I've noticed so far using a center speaker is something more natural sounding especially on vocals happens even when the spread isn't very wide (the wider the spread the more obvious the benefits of the center speaker are). Thanks for posting all your experiments! mike

cjgeraci I agree with you that the 7C and 8B are great sounding I repaired a 7C preamp for a friend and the build quality was the best I have seen from the 1960s. After repairing it I tried it with my Khorns and the combination was just a wonderful match and I also found the Tone controls really helpfull with some Music. I really hated to let it go but I couldn't afford it at the time he was able to sell it to a guy in Japan for $2200. My friend also has the 8B and its the best sounding EL34 amp I've heard. Very natural sound to me. mike

When I've heard Khorns at their best they had incredable depth and layering from front to back with instruments and singers having a very lifelike scale(you could clearly hear the back wall of the recording enviroment).The room was approx. 16x25 and I've heard them setup on a short wall as well as the long wall(my preferance) at different times, but both times there was an incredable soundstage and clarity. The room I've described above was a Demo room for the Klipsch dealership many years ago and another thing that would happen was sometimes you could walk in there and depending on how things where aranged in the room they could sound very disapponinting which showed that the Khorn (like any speaker) needs the cooperation of the room to deliver all its capable of BUT give it a good enviroment and IMO its capable of the best reproduction of a recording I've ever heard. I've had spreads of 11.5', 13.5', 17'and 20.5'in various rooms and my personal experience so far is that the Khorn likes 16' and wider spreads to really open up and deliver the kind of imaging I've experienced from them. If you want to know what frustration is go from 20.5' to 11.5'!!! mike

Enjoy Tom Good example of why this is a great forum with really great people!! Very Generous give away Gary its nice knowing there are people like you on the forum. mike

I've sent you PM thanks Mike

Coytee said: As a partial clarifier, I do not know ANYONE that has tubes and I know even fewer that have Klipsch, let alone, K-horns so leaning on a friend unfortunately, isn't an option. -------------------------- Hey Coytee I live in Maryville,Tn Left you a PM with a Phone No. if you want to contact me. mike

For anyone interested in trying this. I've been using the circuit/setup like Dean posted for several years with my Khorns/Belle. One really good feature I believe is that any characteristic of the main amp is taken on by the center channel amp which will give you the best match between channels if the amps being used are different. I've used a 2A3se amp with a 6BQ5 push/pull mono amp for center channel and the sound is so good I have not felt the need to build a 2A3se center channel amp. Another thing I've done lately is feed the signal from the box into a creek OBH-10 passive volume control into the center channel amp. This way I can control the volume of the center channel or mute it for comparison of with/without the center channels contribution to the sound. This is really important to me because different songs and CD's sometimes benefit from a different center volume setting and being able to do this from my listening position is ideal. mike

So in other words the networks ,driver physical locations and listener locations have to be taken into account when selecting the proper polarity for the individual drivers. mike

I heard the orginal forte in the same room with Khorns using the same equipment and I was very impressed with how close the sound was to the Khorns. I've owned chorus spk. and my preferance would be for the more extended bass and tonal balance of the forte. Both systems will play as loud as I would listen to music. The best thing would be for you to seek out the other models(maybe some forum members in your area could help in this or if any of these come up for sell in your area) and listen to the compromises klipsch made for each design and pick the model that best fits your taste and needs. Enjoy the forte speakers they will definitly give you alot of the Khorn sound for very little money. mike

coytee said: Mike: The watermark seemed to just evaporate out and now I dont see it. If and when these DO go into the basement, it will be on a tile floor over concrete. The walls are block walls w/poured concrete inside. (then Ill drywall the actual interior surface). The downstairs room is something like 16 wide by roughly 24 I think. Been while since Ive measured. Nine foot ceilings. --------------- Man that downstairs room sounds like it has some great potential for an audio room! I would love to have a space like that to work with.Ending up in the basement might be a great thing in the end! mike

great looking Khorns coytee did the water spot you posted about come out OK? what did you end up doing for that? If your basement space is a good size and dry it would be nice to have a space to dedicate to the klipschorns so you can set things up for best acoustic purposes with less compromises maybe.I would love to have mine setup on a "solid" concrete floor. mike

hey Gil here is another shot of the complete picture on pages 26 and 27 of the article. the look on PWK's face is from him sighting down the model railroad train and track mentioned in the article. mike

Hi Bill Do a search under "Check out these 1980s spec sheets" you will see alot of spec sheets and brochures on many klipsch speakers. of course these have the older network/drivers versus the current models. Where you looking for specs on older or new models? anyway its good reading if you haven't seen it. mike

Hi Coytee good to see another local person on the forum and glad to see your getting the Khorns. Your right the McIntosh dealer in Knoxville is Statement Audio you can go to their webb site www.statementaudio.com and click on their links (Audio Refurbishers) and you will see some used McIntosh equipment for sale. Are you happy with the amp your running with the lascala? good tube amps are great with Khorns/Lascala/Belle Klipsch but I would also be open to solid state amps also (I remember a little nad3020 playing on Khorns creating wonderfull sound) and if rock was what I mostly played and for home theater purposes also I believe I would want an amp that could put out at least 20w to 60w. for a medium size room. Anyway enjoy the search and hopefully you can try a variety of amps to see what fits your taste and needs best. mike

Hey Bill glad I could help with the info I've noticed there are lots of good people on this forum always willing to help just curious? aka 126mhz whats it stand for if you want to tell. It just caught my attention. mike

and here is the 2nd page good looking system. mike

Hi Bill Here is the spec sheet on the KP 450 page 1 of 2 mike

heresy2guy your very welcome I'll see what else I can dig up. I also appreciate it when people share articles and information on this forum. I also would encourage anyone else with old literature/articles of Klipsch to post it so that we can preserve/share as much as possible the history of PWK and Klipsch.
