littlebigjoeman Posted March 3, 2004 Share Posted March 3, 2004 i was refered here from audiogon,im bigjoe on audiogon,here's the scoop,1st ill explain my system, 1 mcintosh mc300 amp for the cornwall 1s =300 watts 1mcintosh mc7104 amp for the k horns=200 watts 1mcintosh mc122 amp for my klipsch sub=120 watts 1 mcintosh mq101 equlizer for the cornwalls 1 mcintosh mq101 equlizer for the k horns 1 mcintosh mq 102 equlizer for the sub 1 mcintosh mcd 7007 cd player 1mcintosh mr7082 tuner 1 mcintosh c-38 preamp 1 cary audio tube dac i run my rig in quad with the 3rd amp input on my preamp for the sub,no surround sound,here is my dilema,the k-horns sound like jesus himself is singing to me & the sound is perfect in every way,sub is also perfect but the cornwalls sound very thin in the mids,almost like they are missing true midrange,i have had the mids rebuilt in both cabs from a dealer who never makes mistakes so i know the parts & the work are all good,still bad mids,im thinking of going to the alk crossovers but a guy on audiogon said the alk's were inferior,he also said my crossovers might have a problem,i checked & they both look good with no leaks or visable damage,ihave heard all the stuff about going to tube's to correct the problem but i have been there before & want to stay away from tube amps plus my mac ss amps perform perfectly with the k-horns so the cornwalls should be the same,how can i get better mids & any suggestions on the alk's.

BackBurner Posted March 3, 2004 Share Posted March 3, 2004 Welcome to the forum mike . I'm sure AL will find this thread and defend his cross over design. If not your sure to find the proper help here , some of the more die hards hang out in 2-channel so if your post goes un-noticed down here try it up there . Are you max'd out of range adjustment on your EQ for the corns ? I'd think you should have enough boost there to shape the signal to blend well enough with the k's .

Dflip Posted March 3, 2004 Share Posted March 3, 2004 the cornwalls sound very thin in the mids,almost like they are missing true midrange,i have had the mids rebuilt in both cabs from a dealer who never makes mistakes so i know the parts & the work are all good,still bad mids, ------------------ Ask your question in the two channel forum. Also use the search and type in Cornwall. You will end up with about 10 pages if you go back far enough. Many have used rope caulk on the squawker (amount varies depending on who you talk to). I use about 2" from the magnet towards the mouth of the horn. It helps "tame" the shrillness. The good thing about the mod is it is cheap. Two packs from Home Depot at $2 each, and easy to remove if you don't like it. They aren't Khorns, but can still sound very good. ALK's are not made for Cornwalls any more. They cost about $500, too much money for a speaker that is worth $800 - 1000 on the used market. There were only so many made and don't come available often, although you can get plans for them and make them yourself. Quote Link to comment Share on other sites More sharing options...
3dzapper Posted March 3, 2004 Share Posted March 3, 2004 Mike, Have you owned the Corns since new? Is it possible that a previous owner altered the tap connections on the x-over autoformer. See if you can find a schematic for your type B networks in the search function and check it out. Or maybe someone has a type b you could borrow and try out.

Allan Songer Posted March 4, 2004 Share Posted March 4, 2004 The McIntosh EQ units are designed to be used ONLY with McIntosh speakers. I can only imagine what your Klipschorns sound like being run through one of these. Lose them and you'll be on the right road. Quote Link to comment Share on other sites More sharing options...
chacal Posted March 4, 2004 Share Posted March 4, 2004 Allan, what is so special about the Mac EQ's that they won't work on other speakers? Doesn't an EQ simply vary the level of different frequencies being passed to the amp? Quote Link to comment Share on other sites More sharing options...
littlebigjoeman Posted March 4, 2004 Author Share Posted March 4, 2004 thanks for the info on the x overs,there is 1 response that floored me though,I CAN ONLY IMAGINE WHAT YOUR K HORNS SOUND LIKE WITH A MCINTOSH EQ,wow,when did mcintosh join the likes of low fi, a big misconception is that mac eqs are designed for use with only mcintosh speakers,the mcintosh mq101 is a very simple yet effective eq,it changes the values of 3 areas only,BASS MID & TREBBLE,i can never figure out why some people dump on mac but lets not forget that MCINTOSH & KLIPSCH are the ONLY gear on the planet that you can get all your cash out of when you upgrade, in fact klipsch heritage speakers are exactly the kind of speakers that mcintosh eq's are desibned for.

Al Klappenberger Posted March 4, 2004 Share Posted March 4, 2004 Guys, I am not in agreement about the McIntosh 101 equalizer. It boosts deep bass. Enough of that will blow the woofer driver right out of a Khorn! As to defending my crossovers, no, I will let other have and express their opinions about them. I WILL answer any technical questions about them. That's best done by email though. Al K. ALK Engineering Quote Link to comment Share on other sites More sharing options...
johnnyp Posted March 4, 2004 Share Posted March 4, 2004 Welcome to the Klipsch forum, littlebigjoeman. Now mellow out a little - no one attacked you or your Mac gear. Most here think Mac gear is top notch. We're just surprised you think the Khorn needs an equalizer. For several years of production the Khorn and the Cornwall used the same squawker drivers. If you remove the back cover of your Cornwall and the squawker driver looks like the squawker driver on your Khorn, go ahead and swap one for the other (just unscrew 'em). If the bad midrange sound moves to your Khorn, you have isolated the problem to the driver. Quote Link to comment Share on other sites More sharing options...

hoggy Posted March 5, 2004 Share Posted March 5, 2004 Not sure if I have any idea what I'm about to say but is it possible the squawker wires got reversed when your expert friend rebuilt them? Stranger things have happened. BTW you can see I too like McIntosh. hoggy Quote Link to comment Share on other sites More sharing options...
