    are you having problems making Cornwall  grilles with lambswool-------if yes , there are a few members on the forum which may want to  chime in   and give advice --the key is stretching  2 sides at a time and stapling  rather than gluing -

    That’s exactly what I need, tried glue and got sag in the woofer cavity, I’d love to do my forte 2 in the same cloth. I tried twice and had ok success, but really need it to be as near production quality as possible. It’s possible with the right guidance I could do it, but frustrated enough to pay someone at this point!

    What’s your location? I’ve done a few Cornwall’s and H1’s and H2’s and did a pretty nice job. I’m in deltona Fl

    Hi @Bobby2xs,

     

    Yeah ... had the same problem (almost) :)  Tried various centers and was not impressed. Best solution was using 2 Heresies with a center Heresy on my TV setup. (Also hooked up  are KPT-904's, but hardly ever use them for TV). Sound is excellent, and I am pretty sure you can "flip" the center without any sound problems. (Have my K-510 horns flipped 90 degrees and cannot hear any difference :) )  If you have enough room underneath the TV, that probably is the best way to go.  If not, @Foxman's suggestion for Bob Crites' center channel is interesting - but not familiar with it :( 

     

    But, my center Heresy was "underneath" the TV ... HAHA; in front of the fireplace. Even though we are in Florida and almost never use the fireplace, my wife was "not pleased."  Went back to a phantom 2 speaker setup and have never missed the center :D 

     

    Good luck ... keep us posted.

     

    Cheers, Emile

    I’ve been talking my wife into getting rid of her electric fireplace Entertainmet center for years and losing, as soon as I win (she gets tired of me asking) I’ll put a 3rd Cornwall in! Phantom center does seem better than the Jbs-3 tho!

    Bobby,

     

    Have you considered a single Split La Scala ? That is the best option as far as II am concerned. If a La Scala is too tall, you can set the top section dead center on top of a milk crate and set the bass bin off center to either side of the top hat since the bass is less directional. I need a single Split La Scala with trim like one of these if you are interested in splitng a pair.

    I have a set of series 1s that I had 3 speakers and 1 had a very poor cabinet while the other 2 looked better still needed to have cabinets restored. I decided to mirror finish black lacquer 2 and use the 3rd to make a center channel that would look more like a modern style center using both horns and opted for 2x 6.75” DCM dual 5.5 ohm VC woofers removed from a pair of large bookshelf's. I had to fabricate the entire cabinet and crammed everything in as tightly as possible without loosing strength on motorboard. I used typical techniques for cabinet design with dato cuts to groove sides around motorboard, all block backed seams, 45s on sides inset back piece. All 3/4” 7 layer oak veneer plywood  with no voids. Cab is 100% perfectly square, solid and sounds great, crossover was used with minor tweaks, all caps were tested using ESR meter and were dead on.

     

    Since the woofers are a 5.5ohm load, I added a 15 ohm 10watt resistor to the woofer out put to impeedance match it to retain proper crossover point. I also moved the mids and tweeters down 1 setting on the autoformer to achieve a better sound output that very closely matches the 2 others. Al 3 had the drivers moved to the front of the boards. To keep motorboard strength I did not inset the drivers, I also moved them as close as possible to each other. To mount them on the front required the horns backside of the flanges to be flattened since they are cast with a thicker area in the center of the side flanges that tapers out towards the top and bottom flanges.There was a piece of textured hardboard precision cut to fit over all drivers on all 3 to give it a very different look and make the drivers appear to be flush mounted. All frond edges were rounded to reduce deflection further. 

     

    This design and fabrication took about a week then 2 weeks to finish the cabinet exterior. The other 2 have not had any crossover changes and all caps tested exactly perfect.  This set of 3 sounds better than my series 2 set by far. I would like to sell all 3 or even 5 including the series 2 set also redone in mirror finish black Lacquer. Since I did make the most creative design I could think of the set of 3 really needs to be sold together.

     

    I have named them the Heresy Tiki Series 1. Asking $1000 for the set of 3, $750 for the series 2 set, all 5 for $1500. There's about $750 just in paint and supplies, plus 4 months of all day every day labor that went into these, all 4 regular sized speakers are using all original parts, all caps were tested, all original wires but the series 1 set has updated binding posts.

    If you want to PM me that would be awesome, I think this is excellent! Need to get some cash back up, just bought a bunch of gear. If you send me a PM I’ll get to you when my cash is right!!

  6. I’m not sure why the tweeter is vertical on the academy. Maybe the waveguide helps dispersion? Not trying to be argumentative, that’s what I read about vertical Cornwall and slanted heresy. I’ve also heard mixed reviews on the Academy but I know this KV-3 I have isn’t the right answer for me. And I know the wife isn’t going to let me replace her fireplace home Entertainmet center with another Cornwall! Though out of all the speakers I have the Cornwall are the ones she said I can never get rid of!!

  7. The Cornwall with vertical tweeters were made to be used as a center channel by laying it on its side so the dispersion would be wide. They were made to be used as the center channels today are. The vertical Cornwall were in fact made to be placed on the side with arrows showing that was the correct placement, thus making the squaker and tweeter horizontal for dispersion.

  8. Would turning the heresy on it’s side leave too narrow of a sweet spot? Most of the center horns I’ve seen on center speakers are square horns for off axis dispersion. I would imagine the heresy on its side would make the image tall instead of wide. Really I’m hoping someone has a good set of plans for the heritage center that I referred to in the op.

  9. Garyrc thanks for the reply! I’m familiar with the history, however my space won’t allow for a proper 3rd floor standing speaker. Even the heresy is too large so I need a horizontal speaker.
     

    The academy and KLF-c7 are the best compromise. But I’ve seen a few members that have built a center with 6.5 woofers and a k77 and k55, which I would love to buy if someone can recreate it with a decent crossover. It would be for a 50/50 mix of movies and music. 

  10. Hi all! I’m right outside of Nashville looking to buy a center for my heritage setup. I’ve seen people on here that have built a 3-way center with a mid and tweeter taken from either a Heresy or Cornwall donor. I’m super interested in a build like that! If not I’m looking for an academy or KV-4. I’m running Cornwall L/R and forte 2 surrounds and a KV-3 center in my 5.1setup. Right now and it sounds pretty good, but for those of us that frequent this page, pretty good ain’t gon’ cut it!

    Thanks in advance!

    I've built two custom centers and experimented quite a bit with them. What I would tell people looking to do such a thing is to be aware of lobing issues, which is in fact a thing. The bigger the woofers, the further they are spread apart, and the higher the crossover, the worse this effect is. If you are at the mercy of a factory crossover and are using large'ish woofers, at the minimum try to keep your woofers as close to the middle as possible, don't spread them apart any more than necessary like on post 8. If at all possible try to build something that is vertically aligned.

    Did you build a center like this? With k77’s and a k55? If so maybe you would like to sell, or if you have plans, share them?

    The easiest would be to simply duplicate the Heresy box volume  but in a longer narrower design.   You could even put 2 separate motor boards. One fixed for the woofer, the other for the mid/tweet, square and rotatable to try horizontal or vertical orientation. 

     

    I’m not sure how to get a single woofer to fit under the tv though
