    Jokes?

    My ex-wife found my speaker building obsession, and speaker listening sessions, somewhat over the top and frivolous. She would jokingly ask my friends if their favorite listening chair ensured that their ears were 39" off the floor...or....if there tweeters were at ear level. She even brought out a tape measure one time when I had some friends over listening to some new speaker builds...and measured from floor to ear. I'll admit it was funny. But, I believe this is what she wanted to say when we split up......
  2. He’s 11 years old now, but this pic was when he was about 3-4 years old. I would guess he was around 215-220 in this picture. He used to be quite athletic. I found him on the kitchen Island a couple of times. 32” wasn’t an issue for him to jump up on. Alas, he is getting old, like me.
  3. So…basically I kept the K48 woofer/passive radiator/enclosure from my original 1990 Chorus II’s. I replaced the K79 tweeter with the LMAHL V2 from DaveA. I then replaced the K61 Mid with a A55G V2/K604 horn. I also replaced the 32 year old xover with a new unit from Crites. I followed that up with placing a full shelf brace between the mid and tweeter. Finally, I affixed damping material on the mid horns & driver rear cups; and all the ribs of the woofers and passive radiator frames. I burned it in for about 10 hours. My first impression was that it sounded ‘unfamiliar’…a lot of wonderful sounds but it didn’t seem to be cohesive. I move the speakers around, shut doors, rearranged furniture. I put on background music for 36 hours straight. I followed this up by not playing them at all for a three weeks of weeks. I just wasn’t feeling the love…so, I took a break until I just wanted to listen to my music. Put on some Chris Isaac yesterday…what came out was nothing short of amazing. I followed this up with some acoustic guitar, Whitney Houston, AC/DC, madrigal singers, even some barbershop quartet standards. Everything was sweet, tight, lively, and smooth. Tweeter were a touch string so I backed them off about 2db on my Denon AVR graphic equalizer. They sound fantastic. I love the music coming out of them.
  4. Sherman looks a lot like those Turkish dogs…but he is a Saint Bernard x Bloodhound cross. I asked a vet how he got so big with that cross; vet said it was just the quirk of genetics. This is Sherman with his paws on the floor taking a treat out of my hand….I am 6’5”…my hand is about 7 feet up.
  5. He jumped on an accompanying couch, while playing, and cracked the horizontal wood supports along the bottom of the couch. I took the feet off of this loveseat so that the floor would support his weight…
  6. My daughter did a tic tok video of him a few years back, but I don’t have any vids. This is an unaltered pic of him sitting on an old couch with my wife…he is comically ridiculous.
  7. Sherman...our 234# genetic mutant. That's Clyde, our 155# Saint Bernard behind him; as Sherman plows through the Michigan snow.
  8. I actually purchased a used pair of AE TD15M's off of a gentlement here on this forum....so I am all set. Thank you for taking the time to post this to me.
  9. I will be baking some Paska here in the next couple of weeks. I add Turmeric for a more savory flavor and slightly yellow-er presentation. Good stuff!!
  10. ...and it's only your ears you need to please I just was surprised about the 5db that Klipsch had noted on the Cornwall.
  11. I am surprised at that level of difference between the woofer and mid & tweet - 5 db - and that it still sounds good. I had Meniscus Audio create some new 24db/octave xovers for my Chorus II's, years back, and had them voice them progressively 3-4db down at around 15,000hz, from the woofer level at 60hz. Low level listening was good and absolutely sang like Pavoratti at 110+db with little shrillness (I used to have the kids in the neighborhood dancing in the middle of the road when I turned it up).
  12. Title says is all. Looking for a 4ohm pair of either the FaitalPro 15PR400 or Acoustic Elegance TD15M. I recognize that this is probably wishful thinking....but, doesn't hurt to try.
  13. Voice coil inductance also affects how well the lower sensitivity woofers match up to the higher sensitivitysquawkers in the 400hz-800hz range. Take a woofer with an Le of 1.6 compared to a woofer with an Le of 0.6, ....and the 1.6 Le woofer is going to be general sloping down of several db's in that 400-800 zone compared to the 0.6 Le woofer. The presence region becomes more difficult to control/maintain with a high inductance woofer voice coil, without a zobel. Or...use a woofer that has a low voice coil inductance..mabye 1.0mH or less. Of course once you add in baffle step and other factors, it is more involved; but voice coil inductance is an important aspect to consider.
  14. The LMAHL V2 is what is called out for the Chorus/Chorus II, I believe.
  15. Reminds me of a review of a pair of Sansui speakers from the early-80's. The reviewer noted: "At least you get a lot of hardward for the money"....which was their highest praise for anything about the set.
  16. A zobel network on the woofer could negate the higher Le of the Klipsch and Eminence woofers and mitigate the issue. But, it makes me wonder if there is more going on with a better designed motor when a woofer's Le is well controlled and no zobel is requred on the woofer. ie...maybe it's just a better performing woofer in the 400-800hz region.
  17. The answer is (as with everything else) a definite "maybe they will make a difference". The very low inductance of the Acoustic Elegance woofers voice coils comes into to play, the higher in frequency your design expects out of the woofer. I ran the numbers on the AE TD15M-4 ($459-$599) as a possible replacement for the K48 in my Chorus II (if they ever give out), compared to the FaitalPro 15PR400-4, for about 50% of the price ($271) of the AE ...which also has a voice coil with vary low inductance. For example, the TD15M-4 has an Le of .20mH. The 15PR400-4 has an Le of .60mH. The K48 has an Le of 1.00mH. Below 300hz...the difference in the freq curve (when Le is taken into account) is very little. The F3 is about the same and the SPL at 300hz is close. But, at 300-400hz and higher, the low Le of the AE begins to have a telling affect. Below is a little chart I ran using Unibox (I like this little program). Notice how the higher in frequency the woofer goes, the more the Le rolls off the SPL's. At 400hz the K48 is starting to roll off the higher it goes, while the AE SPL's are staying the same. Where that comes into play is when your woofer meets a Mid/Tweet at between 400-800hz. The AE will have a minimum SPL 3-4db greater SPL in this region (all other things being equal) compared to the K48 with the higher VC inductance...which makes mating the woofers and tweeter with crossovers 'maybe' easier. I think it can be said that the frequencies between 300hz and 800hz will have more 'presence' than with the K48 in the Chorus II. I would imagine that at 300-400hz and below, box tuning can mitigate any frequency related differences between the woofers. Distortion figures are probably lower in the AE and FaitalPro, but whether or not it could be heard in the 50hz-350hz region is debatable. I have reviewed every Eminence woofer that might replace the K48 and none of them (on paper) are the equal of the TD15M-4 or 15PR400-4 (or K48)....although at 50% to 75% cheaper, the Eminence woofers are the obvious better value. If you have the cash and are crossing over above 400hz, as a direct radiator, the AE TD15M-4 and the FaitalPro 15PR400-4 are just plain hard to beat. Neither of them bests the K48 in the lower regions below 100hz. The K48 is a beast down there. If I had the money, I would purchase the AE TD15M-4 (but I don't). In the future, I will most likely purchase the FaitalPro 15PR400-4. FWIW....these are some facts and figures, with my added in opinions. I could be all wet, but I don't think so.

  18. Cool in the fact that the EV 'D' and their vented midrange were the coolest thing back in '78!
  19. Good looking BH. People are always surprised at how big and strong BH can be.
  20. Truth...Dave. I also have a large male Saint Bernard and a 125# Bloodhound. I think I remember you mentioning living rural in Tennessee....of which Bloodhounds seem endemic. Michiganders don't recognize Bloodhounds right away. But...yes, slingers on walls, furniture, windows, and speakes, are daily cleaning opportunies. We actually have a 'dog car' that we use to transport our canines...

    KSM-15 II

    I just purchased these. I live in Metro Detroit and will be picking these up in the next day or two. I needed those K604 horns for the screw in A55G/2 mid drivers that I purchased for my Chorus II build. Along with the LMAHL V2 drivers that I have on-hand, new Crites x-over, and the venerable K48 woofer already in the Chorus II, I believe my build is ON!! Psyched!
  22. Thank you for adding to this conversation. The Chorus II are a great set of speakers. I am continually on the outlook for the KP-301 horns. I look forward to seeing what GR Research does!!
  23. Thanks for the offer. We shall see how this rolls out.
  24. Part of the problem with modifying the Chorus speakers with any off the shelf passive 3-way xover is that the Chorus K-48 woofer (which I really like) is not in any of the other Heritage speakers (mostly K-33's, etc). Combined with me not being a passive crossover expert, or wanting to go 3 way active, puts me in a little bit of a bind. I'll figure it out...just have to ask for some help along the way.
