Rob, So you didn't get eaten by bears, (glad to hear that). THe Khorns fit in so well it is like they have been here for years. The wife really likes them as well Marvel, on a clear night you can actually see the milky way. There are not any street lights for at least 10 miles and Flagstaff has an ordinance about minimal night lights for like stores and malls because of the Lowell Observatory in the city limits. I am about 10 miles outside the city limits

From a post I made a few weeks back, i was told a Cornwall would make a great center fill speaker for my Khorns, would this also be a good center speaker for 7.1? Khorns in front, Belles in Rear and Heresy's for surround? I have relatives in Napa. He also has another one circa 1966, my Khorns are 1997, which would you choose? Jack

I think the reason nobody has mentioned everyone hears differently is because that IS a known fact. I know I have a high end loss, but I also know my equipment well enough to make it enjoyable for those who don't have a hearing loss.

Paul never done a 206, but on my glass panel macs the knobs pull off and then it should just be the endcaps Jack

different is an actual state better is only relative

Different does not necessarily mean better make a change, yes it sounds different, but does it necessarily sound better Can't several things sound good without sounding better?, can't they just sound different?

Not necessarily... this all started way early in the post, all I did was point out the possible dangers, I have actually used a combination of active/passive using the HF and LF binding posts. No amplifier will care if there is a little overlap in bandwidth but if you take an amp that say only drives a tweeter with a passive xo at 7.5khz and the signal contains excessive LF content, that is not good, beside you are defeating the true purpose of multi-amping. With active xo the amp only has to reproduce a small part of the entire musical spectrum. this is the whole concept behind using powered subwoofers. By using active XO the improvements are much like using monoblocks. I did Pro sound from 1969 until 1979, we always used a combination of active/passive xo's, often letting drivers roll off naturally. In my current home setup I use a combination of active/passive but I don't feed an amp full bandwidth with a passive only passing a couple octaves of the spectrum. All of my Paradigm Studio Reference have LF/HF binding posts, I have experimented. All of my amps are McIntosh both tube and SS. I personally do not recommend it FWIW All I said was this procedure should not be automatically taken for granted, that there could be risk involved Active xo's are not rocket science, neither is the concept. In my opinion the passive bi-amping procedure reaches the factor of dimenishing returns way before the benefits. You are not taking advantage of splitting the bandwidth that the amp has to reproduce

So now we are getting to the bottom of this. Maybe todays SS technology can handle passive bi-amping but I know when I was still doing eletronic repair in the early 70's you could blow SS finals by looking at them wrong and it has been verrified by who I consider an expert (DeanG) that this procedure can be harmful to tubes. The point I was trying to make is this, since it is not proven all amps can handle this and there is no way of telling what amps the user has or plans to use that this could be damaging to your amps. To advocate something that could possibly damage someone's equipment is wrong. Unless someone wants to compile a list of what amps can handle this, I believe it would be easier to educate the user on how to use an electronic crossover since there is no risk involved. Active bi-amping has so many more benefits, one being each amp only has to reproduce a portion of the audio spectrum which reduces IM distortion (I Believe)

They could be early DuKanes Or Altecs. I'll have to sift thru some of my old paperwork. I know I have seen them before, just too many years have passed. I believe my next door neighbor when I was a kid had one. He used to do electronic servicing in his garage. He was the one who got me interested in electronics in the first place

Above comment directed to steve donaldson

I'll be sure to never patronize your place of business, your childish nature must be in direct proportion to your age. I have seen amps damaged by just such stituations, but I am not going to get into this discussion with an inexpereinced kid Bye~~~

Latest change. I have a Paradigm Servo 15 sub with the paradigm X30 subwoofer control which is an active xover with gain, crossover freq and phase controls. I have it set at about 28 hz, so the sub kicks in where the K's roll off. A little more tweaking, maybe get out my pink noise spectrum analyzer... It sounds pretty darn good Having way to much fun Jack

Speakerfritz, I can't help but shake my head. First if someone doesn't or can't understand the operation of an active xo, they aren't going to know or want what bi-amping has to offer. only a few of the active xo's out there allow excessive overlap of the bands, from an electrical standpoint it requires duplication or triplication of the circuits, most simply give you a variance of where the crossover point is with individual gain controls for each segmented spectrum. There is a big difference in momentry impedance fluctuations (which are present in all "properly" loaded amplifiers) versus constant impedance mismatch such as would be in the described method of "passive" bi-amping I guess is what you would call it Like I said I need to just walk away from this one...

Ok, I am just going to calmly walk away from this thread, bite my toungue and let you believe what you want to believe "You could send to much power to a part and kill it." I don't know who you think you are talking to here, but ... None of your points .. oh nevermind

What is so difficult about using an active xo? they are not voodoo

Ok, I put a couple pair of Ionovacs on top, left the Khorn as is, using an electronic crossover at 3.5khz powering the Ionovacs wih my MC240, Khorns are still powered by the MC150. Result? the transparancy just tripled, the soundstage is more gigantic than it was... Now to get the Belles in the rear with 16ms delay powered by a MC2100 completely unbelievable Jack

Seti, You have a PM (momentarily) Jack

Kaiser, Talk the wife into a trip to Sedona, I'm just a little past that and I should have everything completed by then (yea right) Stop by for a look, see, hear. Besides like Gilbert said Hiway 89A between Sedona and Flag is probably the most awesome drive anyone can take Parrott [] Oldbuckster, I'm still sore from moving the khorns in the house. I am satisfied, when I told my wife i was satisfied (for the moment) I thought I was going to be a widower! Jack

Oh yea, I promised I would list out the equip on the racks Rack on the Left (top to bottom) Project Turntable w/ Sumiko Oyster Cart McIntosh MR7084 Tuner McIntosh C39 Preamp McIntosh Mac 3 DAC McIntosh MI 3 scope McIntosh MCD7000 CD Rack In the Middle Audio Control C101 EQ / Spectrum Analyzer DVD Liteon Recorder Philips DVD Recorder 3 Univeral remote control MRF 300 Multi-Zone RF Receiver With RFX-150 Antenna / Paradigm X30 Subwoofer Control Philips CDR Gaines Audio 8 channel active balanced line driver 2 Marchand Electronics XM93 Electronic Crossovers Sony MDS JE330 Minidisk Sony MDS JB920 Minidisk VCR Right Rack Sat Rec 480i ReplayTV 2 Zektor HDS4 video Switch Samsung TS160 HiDef Sat Rec Anthem AVM20 7.1 DD/DTS preamp Yamaha C920 DVD/DVDA Zektor HDS4.2 Zektor MAS3 Denon DVD 2900 DVD/DVDA/SACD 3 Sony DVP-CX985V 400 disc DVD changers and a whole bunch more stuff in the room behind the racks So now ya know (oh and 16 vicious pit bulls running loose on the property)

Well after 2 days of almost nonstop listening, if someone was to ask if I thought it was money well spent? my answer would be YES! I'm goning to have to tag which tracks not to listen to on the K's tho. Any inaccuracies in the recording and they jump right out in your face. A poor recording on the Khorns is terrible, a great recording is wonderful Oldbuckster, I'd rather be old and have Khorns than to be young and not have Khorns. I've been collecting Mac for over 30 years. there are a few other pieces scattered throughout the house Now i think it is time to start trying other things, like my tubed 240, an Ionovac or two, moving the Belles in the rear for some ambience. Off to hibernation again for a day or two

Gilbert, I make that drive every chance I get, anytime we have company we plan a trip to Sedona. Have you been to Jerome? Strange little town built on the side of the mountain? Jack

Congrats on the heresy's! Enjoy their great sound!

Duke, Didn't doubt you for a second... Now if only all sound engineers were created equal... Some cuts sound wonderful... Others, reject, buzz I've read it here on the forum over and over, but if there is any inaccuracies in the recording, the Khorn will point it out

and YES if anyone happens to be passing thru, you are more than welcome to stop in for a tour

Wow! Thanks guys! I really appreciate all the compliments, I'll try to put together some screen shots and descriptions of the automation system and some more detail on the audio gear. I've been a hardware geek since I put together my first heathkit back in 1960. About the Ionovacs, yes the 3 on top of the Belles are called Duk10's the other 3 on each side are Duk5's they were made to retrofit Patricians and Khorns way back when. Exactly the same except the power supply on the Duk5 is on a 6 ft cable. I also have 2 prototypes (from what one of the original Dukane engineers remembers there was less than 20 made) There is a post from a few weeks back on here, WAF, yes I am the absolutely luckiest when it comes to WAF, my wife enjoys a lot of the technology as well. I am still in progress with all of this. I only moved to Flag 1 year ago and the addition was just finished in April (were we could move in) I still have paint touchup and baseboards etc to do. I had my house in California all automated, this is my second time at doing this In a nutshell the home automation system controls all the lights in the house from a centrally located touchscreen, and every door and window is also monitored. almost all the automation functions and status are reported via voice (and I might add, the voice is distributed using a McIntosh MC50!) we are woken in the morning by voice, read our daily horoscopes, read any appointments and tasks. The home automation computers name is Susi, she even tells you the time every hour with a "the time is 8 O;clock pm, coo coo, coo coo. I have started implementing open air voice recognition, so I can talk to her, The alarm potion of the system is controlled via a finger print reader. I have RFID on the vehicles which open the electric gates to the property automatically upon arrival, but only for me and the wife. Automation is a blast The video system has 3-400 disc dvd changers, all the DVD info is accessible from the touch screen. I am just starting to integrate the video system with the automation system. I'll see if I can get some screen shots up in the morning, I have a new pair of Khorns waiting to play for me!
