The crossovers are on their way. I am sure Tom will give them a good home. Gary

I purchased new Khorns in 1992. In 2002 I replaced the AK-3 crossovers with ALK crossovers. If you can use the AK-3 crossovers I will ship them to you for the cost of postage. Send me a PM. Gary

try a search in Technical Forum for subject Sealing Bass Bin of Khorn. I think the photo titled semi-false_3.jpg id the photo that you are seeking.

Q-man, I like the idea of a corner board after I permanently fasten the mdf to the plasterboard. I think that it would improve the possibility of a good seal between the insulation on the tail board and the wall. I am unsure of the physics of the problem, but I am assuming that we are trying to prevent the escape of the presure waves as they travel down the exponential horn. I still want the insulation to seal the tail board to the corner board/wall. Gary

Playntheblues...As I now look at photo #4, I see that the pipe insulation does not go all the way to the bottom of the tailboard. I will plug the hole with more insulation. Remember the finger in the dike

Playntheblues....requested photo of the base of the tailboard.

Q-man...I agree with the thought that the ALK improves the bass. However, at the time that I installed the ALK I was impatient and changed from ss to tube pre-amp and amp all at the same time. I did the "semi-false" project after these major changes so I was confident about making statements that I did. Playntheblues...I was also faced with the problem that the tailboard is not straight at the bottom. I just made sure that the pipe insulation followed the cutout. I then smeared some water based paint on the mdf and positioned the K-horn. From the imprent on the paint, I am confortable that the insulation sealed to the mdf all the way to the bottom. It is my understanding that the cutout is to allow the K-horn to be place in corners where there wood molding is at the base. But the cutout was much to large for my molding.

HDBR, I can assure you that more than a FEW members react to your valuable comments. The problem is that you are speaking into the great abiss and don't hear many echos. For myself, I have increased my knowledge with every one of your posts over the last 2 years. Thanks. Gary

I purchased my Klipschorns new in 1992. I discovered this forum in 2001. I believe that the bass from my khorns is improved thanks to the ideas from this forum. Here are the steps that each contributed to "tight quick bass". First improvement was pipe insulation on the tailboard. Next someone mentioned that "california" plasterboard did not stop low frequencies. I purchased 41" squares of 3/4" mdf to re-inforce the plasterboard. I just slipped the squares between the khorn and the walls. Noticable improvement. Since the khorn was sitting on carpet with pads, I next purchased a right triangle with 41" sides of 1" mdf. Again an improvement. Now that the khorn was sitting on a hard surface, I removed the sliders. I know that I should not have doubted HDBR, but I was amazed that it made a difference. Every 2 or 3 months I reverse the tweeks just to make sure the difference is still present. I am now ready to fix the mdf to the walls and paint. My term for this tweek is "semi-false corners". I have attached three photos on seperate posts. Gary

Justin, I pray for your speedy recovery. I have enjoyed your posts via this forum. Gary

As SCOOTERDOG has mentioned, the data on the first members responding to this poll is interesting. Thirty-one respondants represent 480 years of listening to Klipsch "heritage series" speakers. Average age for first purchase is 29 years and current average age is 44 years. Average years with Klipsch speakers is 15 years per person. This is my favorite forum for interesting discussions and valuable information. Gary

1. 1992 Klipschorns, walnut oil 2. 54 3. 64 4. I fell in love with the corner horns in 1955/56 when I could not afford them. I bought a new pair in 1992. 5. I want to hear the Jubilee. If it breaks my budget (retired), then I want to add two more Khorns and a center ( Belle ? ) for the new multichannel media. 6. There must be some "politics" behind this question? What I little information I have heard, it seems like the Jubliee will be the "King" of the Klipsch speakers. My answer is "yes". Regards, Gary

Malcolm, thanks for the feedback. Forty watts and a little more courage did the trick. It was past my bedtime and I did not want to make a mistake. I am now enjoying the ALK crossover and rewire job. Gary
