  1. Excellent info Artto and Marvel! I think the entire committee is looking at this thread now! [] I also think using curtains might have a good effect. I also think that having 100 or so folks sitting in upholstered chairs would calm the sound more than they realize. The current 'sanctuary space' (as a Unitarian, can I use the word sanctuary?) anyway, I LOVE that space as there are no parallel surfaces and the acoustic is just 'wet enough' so that singing is wonderfully enhanced. I also know it's easier to reduce reverberation than to add it - except by electronic means. thanks again! Forrest
  2. Hello all! I use a couple pairs of my speakers (Cornwalls Heresys) as a PA for my church. We recently built a new building - and, as usual, no thought to acoustics was given until they found the room too lively. I wasn't asked to be a part of the planning, but I did get wind of what was currently going on with 'fixing' the sound. What do you think of this plan of attack outlined in the emails below. I personally would love to see tapestrys and carpets instead of acoustic panels (boring). All help and advice appreciated. We don't have the funds to do what they are considering doing, and I feel they will hate the look. I know this place knows audio! Help!! and many thanks.... Forrest the email: HI guys and gal, The bit of homework that I’ve done so far on acoustic panels. Given our space in the social hall- 45’ x 50’ x 10 or 12’ ceilings, Tile floor, dry wall ceilings and walls, with some glass. Here’s what I’m finding with some consistency. An acoustic panel 2’x 4’x 2” covered in a hemp/jute material with sound dampening filling, runs about $60 per panel. An on-line analysis of these features by ATS Acoustics suggests a minimum of 57 panels and 86 would be on the high end. This would run somewhere around $3,600 with shipping. Speaking with a representative of Audio-Mute Corp. suggests a lower expenditure. They state for this size room you would need 15-20% wall coverage with acoustic panels. Approx. 40 panels would be equal to that amount with a similar price tag. With shipping an approximate cost would be $3,000. Another member's suggested company (Acoustimac) has the same size panels for $49.95. (The $25 panel noted in the e-mail is much smaller.) The minimum number of panels suggested for the space is 50, $2,500 prior to shipping. I considered the idea of building our own but I’m not sure would could make ones that pass a fire inspection. Acoustic panel are made to be flame resistant. There are such things as ceiling baffles, but I’d personally hate to see stuff hanging from the ceiling. As it is, the mounts for these acoustic panels will make the space pretty unusable for hanging an art show. Each panel requires a hooking system (a flange) mounted permanently into the drywall. We could remove the panel but the flange would be displayed. The two inch thickness and relative thin panel (24” wide) means that only very small works could be hung, for fear of snagging the jute covers. I forwarded the following attachments to my committee but haven’t had any feedback yet. Something to chew on.
  3. wow... thread from back a ways, and you're still at it with the hi-fi history. You have a great site, and you KNOW you're always welcome in Bowling Green. [Y] peace, Forrest
  4. Well, I'm going to keep them. The Klipschorns will go to some lucky new home in November, but first they will hang out with my son in his apartment for a few months. If it were just for the sound alone, the Khorns with a sub that dug to subsonic levels would be best, but the history of these Patricians coupled with their beauty makes me want to hang on to them. Plus, I can always score another set of Khorns - not to make them sound 'common' as they are far from that - but certainly more available than Patricians. Plus the patricians look good in the house! I'm thinking of putting together a 'listening' weekend ... either 7/21-22 7/28-29 or 8/4-5 I'll be a single man for about 5 weeks and can have lots of speakers in the house. I'll have my 1976 Klipschorns & Patricians in the 4 corners, 1976 Cornwalls and Tannoy SGM 10s there as well. Scott 299B and 355/208 combo, and possibly the Altecs will be up and running by that point. Not sure. Of course, if you wish to bring some of your speakers/amps/turntables/etc. you would be welcome and ENCOURAGED to do so. any interest? Bowling Green KY is a pretty cool vacation spot if you want other things to do. Corvette Museum, Mammoth Cave, great local eating places. let me know... this would be fun to do Forrest
  5. Gary, I have that horn in my newly restored Patrician 800s. Fantastic imaging, VERY good low level sound, extremely efficient. I don't think you could lose money on these if you didn't like them. Forrest
  6. Last year I reglazed all the windows and went through the main listening space to eliminate all rattles, buzzes and squeaks. Plaster walls don't usually rattle. [] Forrest
  7. In Da House! Thanks Bill! Seti first turned me on to that schematic, but it took another user to remind me. I sent the crossovers to Bob Crites, who speaks the language you do and truly 'gets' speakers. He rebuilt them as they were and commented on how some of the specs were different... had me measure resistance and all that stuff. Speaking of stuff, I wish I understood that stuff, it would make it seem more legit somehow. I did trace the wires somewhat and I could figure out how they needed to be wired. I was so meticulous taking it apart that I was certain how I found it was the correct wiring. Thank goodness for the internet! My son brought some of his dubstep music over, very cool genre and we let it crank. Oh my goodness. These are VERY choice. Checking out Beethoven at the moment. Life is good Forrest
  8. (the below is from an email to Seti, who's been in the loop for a while. ... just didn't want to type out the thoughts again) After getting them into the house yesterday and hooking them up to my H.H. Scott 355/208 combo, it was something of an anti-climax. They seemed anemic, and while the bass was clearly 'there', things were muddy and not well defined. Something wasn't right, or if everything WAS right I couldn't see why folks would be excited about these monsters. I put the 355 into mono mode and couldn't locate the 'invisible' center speaker, so figured I had wired them incorrectly even though I had marked EVERYTHING as it came out of the boxes - even down to which screws went where on the cabinets. Oh well, it was late and there was no time (actually too tired) to fix them last night. I was SO disappointed. Got back into both boxes today to check against a schematic JJBlue84 had posted over at Audiokarma.org. Get this - the tweeters and the squawker were both wired red to red (pos) and black to black (neg). The schematic called for everything EXCEPT the 12" woofer to be wired Black to Red (pos) and Red to black (neg) As I said, I had marked EVERYTHING as it came out of those boxes, so there's something of a mystery going on. I think it may explain the use of finishing nails on the front of the box. Here's my theory, they didn't sound 'right' , but certainly better than your average stereo, so somebody at some point tried to go inside, and stripped the screws off the front molding because that is the WRONG way to get inside, even though it would appear 'easier'. When they realized the effort involved, plus the fact that they were positioned a few feet off the ground to begin with (and weigh 315 pounds!!!) they probably said 'screw it'. Now ... with the speakers wired correctly, I could find the invisible center speaker with the source on mono, meaning they were in phase with each other. The sound??? OH MY... really good. Great sound stage and clarity. Khorn slayer? No way, but every bit a kissing cousin. I still prefer the authority and muscularity of the horn loaded bass, but the Patricians deliver. Of that there is NO doubt. My son came over a few moments ago and brought some techno music. They definitely dig deeper than the Khorns. The supreme test for me was how they sound at low volume. It's one of the features that made me fall in love with Cornwalls and Klipschorns - delicious. full, sweet and clear at low volumes. The Patricians are the same way. As they say, no replacement for displacement. They are not as efficient as the Khorns, so it takes more juice, but the 208 at ~30 watts a side (7591 tubes) is plenty loud if I want it, and really nice at low volume (most of the time I listen at low volume). The Altec 1658a mono blocks are rated at 40 watts (EL84 based). So when I get those going it'll be interesting how they sound. Here are the resistance values I measured from the drivers Box one: measured at the terminals with crossovers in the chain and the speaker by itself (marked alone) 30W - 6.0 5.0 (alone) LF (12") - 6.3 8.7 (alone) HF (mid horn) 1.8 13.2 (alone) VHF (350) .5 7.1 (alone) Box two: 30W - 6.0 5.0 (alone) LF (12") - 6.2 8.4 (alone) HF (mid horn) 1.7 13.6 (alone) VHF (350) .5 9.3 (alone) Forrest
  9. Good news is... They're DONE. Well, almost done. Have to get a few screws to replace warped ones, but functionally, they are DONE. Sat back and listened for a bit in the garage last night. Nice. Will move them into the Khorn spot soon - importantly, corners. They are definitely not meant for near field listening, I don't think. This has been a fun and highly satisfactory project. I'm waiting for some pics to load up and then I'll post a link. Here ya go, pics here above link takes you here http://s140.photobucket.com/albums/r21/woodogs-world/Patrician%20800/Done5142012/ will post a video that will tell you nothing about how they sound. In fact I guarantee they'll sound just like your computer speakers. video here all best, Forrest
  10. Got one of them finished! Got one of em finished and the other one will have to wait until tomorrow. Also, have to check to be sure the woofer is in phase with the rest of the cabinet. I hooked them up like they came out (I had marked EVERYTHING) but in looking closer, all the other drivers in each cabinet are red to positive except the woofer, which is red to negative. Don't think it's supposed to be that way. However, the sound, NICE. First music across them was Scarlet Begonias (Grateful Dead) which just happened to be on the radio. The attenuators go from nothing to wide open, so there's a lot of color available with these babies. tuned the station to a hip/hop techno station and the low end really shows itself! Khorn slayer... probably not, but they aren't in the spots the Khorns occupy, nor are they being driven by the same amp either. Can't wait to get the other unit together tomorrow and listen to them together. Pics of the finished one here http://s140.photobucket.com/albums/r...0800/finished/ (which will tell you NOTHING about the way it sounds, but still)... also a cameo by my friend Tim who is another crazy audio enthusiast Forrest
  11. Bill, the link worked fine. I really like the back panel on your pair. !! Forrest
  12. Waiting for pics to upload to photobucket as I write. Yesterday found some detail that had to be done with clamping and cracks in the molding. Used shims made from the old speaker cloth to put in the holes so the molding would screw in snugly. They were previously stripped which explained the finishing nails used on the front. At any rate, the directions on the glue said clamp for 30 minutes but do not stress the joints for 24 hours, so this afternoon the boxes will be ready to put the speakers back in. I have the crossovers mounted and got another two boards cut that I'll mount the attenuators on (I wanted to keep the original panels untouched). I won't stain those since they will be hidden from sight, but I'm sure it'll look okay. Bob Crites does really fine work as you well know! Oh, and if anyone stumbles on this thread who wants hi-rez photos of the crossovers, just drop me a line and I'll send them to you. so close... Forrest Pics of yesterday's efforts
  13. Dang... didn't get them done this weekend. Will probably be next weekend. Whoever decided not to standardize staple guns and staples should be shot. I spent a very frustrating Sunday afternoon looking for such and still didn't end up with the correct stuff. Cabinets sure are pretty, though. Forrest
  14. Update: I have the speaker cloth in. The crossovers are back. Still have some minor blemish repair to do as well as a fabrication of a panel to mount the new attenuators in (pics will be forthcoming, but you'll see what I'm talking about). Removal of staples and the purchase of a staple gun to mount the fabric. I think they'll be done by the end of the weekend. As always, I plan to take a LOT of pictures and post the link to them. Colter - I will send you the old cloth as I promised. The stuff from WendelFabrics is pretty nice. Excited? Yes! [] Forrest
  15. Thanks Bill for an informative post on these beasties! I'll have my crossovers coming back from Bob Crites and as soon as the grill cloth arrives I'll have them back up. The info on rotating the woofer is especially nice as I was intending to keep all drivers in their original orientation. I'll rotate it! There was a pair in similar style on Ebay recently that didn't even get a nibble at $7500, so ya never know. The plan was to keep these around for a year or so and enjoy them, then sell to finance a rebuild of my piano that I also bought, but after looking into the guts of the piano (a Baldwin model L from 1954) I realize it's not going to cost what I thought it would, especially doing the work myself, which I enjoy, so knowing me I'll probalby keep these if the sound is pleasing enough. [] On one of the speakers the quarter round molding shattered when coming off (my ignorance in how they were mounted) but I got it glued back together fairly well. Might get a woodworker to reconstruct a new one. There's NO way to replace the grill cloth without total disassembly - same goes for the molding. Again, thanks for the information. I was fortunate to be able to get these and want to get them back as close as possible to original. all best, Forrest
