  1. I think I found it. This photo looks most like it. No front photo unfortunately, but it looks identical from the back (minus the label). T35B
  2. I had a look online for TW-35, but all the examples I could find had a ribbed horn lens instead of the smooth one that I have at hand.
  3. Thanks for identifying it filmofreddy. What is it about it that makes it not so great?
  4. Hi All. I picked up a single tweeter today and would like some help identifying it. The seller said it was a Jensen tweeter from the 1950s, but I think it looks more like an EV tweeter. There are no identifying markings or labels on the tweeter. The horn front is 1.3 X 4.5 inches, and the horn with driver are 3 inches from front to back (11.5 X 3.25 cm and 7.5 cm deep). Pictures attached. I'm hoping to use it as the tweeter in a three way center channel speaker I have in mind. Any help with identifying it that you can provide will be be much appreciated. Cheers, Tiz
  5. Thanks Islander. If I buy two, I'm unlikely to ever sell them, me being me. I'll try that after I give this a bit more of a chance.
  6. Sorry for not being more clear. As Geoff already mentioned, Toronto is the place, and surrounding area.
  7. The text portion of the Ebay ad differs somewhat from what I quoted. [Moderator Comment: I had to remove the ad because of where it went, so you may need to repost whatever quotes you wish to give them context again. Your posts were informative and fine, it is only because of where this went]
  8. I've got a pair of Level 1 for a 300B build that is in the works. Here is a quote from O-netics that explains the differences... "Our level one audio outputs will outperform all of the famed "golden age" of audio outputs. Level two outputs add even finer detail to the already astonishing amount of information found in level one devices, due to a core material change. Level three goes all out, with 16 interleaved sectors in place of 10, even thinner high performance dielectric barrier material and extremly small diameter wire strands, woven into Litz type 2 cabling, for all secondary windings. In addition to this the core material is also changed. We do not use silver or impossible to maintain oxygen free copper winding wire, nickle or amorphous core material, or any of the other popular material driven aids. Instead we utilize commercial materials in subtly different designs with very specific motifs that come from our unique R&D program. Our designs rival and typically exceed the finest devices provided by our esteemed competitors, in information depth, accuracy of placement in a perceived sound field and increased levels of tone and transient color and internal gradient structure." The prices go up quickly with each level that you go up. I haven't heard mine yet, but the reports are good. I was in contact with BudP when I bought them, and he is a very knowledgeable and helpful gent.
  9. Hi All. I'm looking for a single Heritage speaker to serve as a center channel in a home theatre that I'm working on. I have pairs of Quartets, La Scalas, Tangent 500 and Heresy II speakers, but will look at any Heritage three way. Please let me know if you have a single laying about that you would like to sell. The speaker doesn't need to be in great aesthetic shape, and I will consider speakers with some non working drivers as well. Please let me know if you have anything to sell. Something within a reasonable drive from the GTA would be great. Cheers, Tiz
  10. Thanks for the Tangent 30 crossover schematic Moray, and thanks to Bob Crites as well. I am pretty sure that this schematic does not exist anywhere else on the web, as I have done a lot of searching as well. Much appreciated!
  11. Hello All. I've been searching, without any success, for a crossover schematic for my Tangent 30 speakers, and am hoping that someone has one handy. The crossovers in my pair of Tangent 30 appear to have been modified, as the capacitors don't match from one to the other. Any help with this would be much appreciated, as I don't think there is a schematic available for any of the Tangents other than those that use the drivers and crossovers of the Heresy (Tangent 400, 4000). Thanks in advance! Cheers, Tiz
  12. Yeah sure, you’re rational. That’s what makes you comfortable suggesting forum members go elsewhere. Whatever.
  13. I thought Chris A was talking about the midrange horn’s radiating pattern coming out of it and then rolling around and off the top, and not the vibrations of the top panel. I would think that the top panel vibrations would be fairly low in level.
  14. I get it now. I didn’t know what I was looking at.
  15. How are these panels situated with respect to the speakers and your room?
  16. Thanks for all the replies and the excellent information contained within. I am getting a basement area ready for a listening room/home theatre, and will be using a DIY pair of Klipsch inspired speakers there. My La Scalas are upstairs in the family room and will remain there, unmolested. The ceiling in the new room is around 7.5’. Would a carpet and sound absorbing panels on the ceiling be the ticket if I use Klipsch Heritage style horns in my DIY speaker? Alternately, as may end up being the case, if I use CD horns instead, will these room treatments be less needed?
  17. Yes. A very good idea, and not a permanent thing either.
  18. I wouldn’t modify my La Scalas, but I will go to the effort of terminating the horns better in future DIY speaker builds that include horns. It’s a matter of many small differences adding up to larger ones. That’s why I asked about the LS II. Perhaps the termination isn’t audible. I wonder if anyone has modified their La Scalas to create a better transition, and have measurements or listening impressions to share?
  19. I just finished watching the video referenced by WMcD (thanks!), and it looks like the termination of the tweeter horn in the LS II is better than in my LS. The tweeter horn is surface mounted in the LS II. The midrange horn termination in the LSII is the same as the LS.
  20. Thanks for the replies and photos. I have been doing some reading lately about horn mouth termination and it’s impact on measured horn performance and subjective listening. I own a pair of 1976 La Scalas, and have wondered why they have a straight cutout for the midrange and tweeter horn instead of having the transition be bevelled to follow the angle of the horn’s mouth. Given the wavelengths in each case, this would seem to be a bigger issue for the tweeter horn, but is not ideal in either case. This is based upon what I have been reading online. I was wondering if the LS II corrected this. It looks like it is made in the same way as the older LS. The transition from horn mouth to the room is straight, and thereby interupts the expansion of the horn with a constriction and a small lip at a point where it would be best to have either a bevelled motorboard matching the line of the horn, or this bevel in addition to a rounded termination of some sort. They say that a little information can be a bad thing, and I am a relative newbie with respect to horn speakers, so I may be off base about this.
