Q-Man

Thank you everyone. I see this Forum is just like it used to be. Everyone helping each other out. Mark at Paduch Home Theater had me give him a dimensional drawing of my room, and my speaker layout. He is giving it to the commercial design department and they are supposed to get back with him or me with their recommendations. Time to put the LaScalas and Klipschorns for sale. Can't believe that it has been about 20 years since I changed anything but the sub and TV.

I'm not sure if this will work, so please bare with me. I had trouble logging in so I found one of my old post to reply to. Life got busy with opening up a cabinet business and I didn't make too many changes to my system. I also haven't been in contact with the good friends and people on this Forum that helped me out with my modifications. I may mention names later. I'm finally going to get into Dolby Atmos and purchased a different processor to do so. Also getting ready to buy some different equipment. Next purchase will be the Magnetar UPD-800 Blu-ray player. I have been trying to purchase some Klipsch Cinema Surround speakers, but I'm having trouble finding a dealer. I have to search a little harder. I'm thinking of the KPT-12-VB, KPT-8-VB, Kpt-1200-VBM . I need 2 surrounds, and I might use them for 4 ceiling mounted Atmos speakers. Have to see what kind of frequency response is actually sent to the those Atmos channels. With these changes I'm going to sell 2 pairs of LaScalas , 1 pair of Klipschorns. The Klipschorns are stock, they used to be my benchmark speaker that I used when modifying other speakers. I havent listened to them in years. The LaScalas are my front and rear height speakers which I can't use as surrounds and ceiling speakers. I'll probably list these in the Garage sale section one of these days before going to eBay. That's all I'm going to say for now. I want to see if this reply post. Then I'll try starting a new one. I have to search the members list to see if some of the old timers like me are still active here. May have to change my old pass word, and email address. Q-Man

In my home theater I cross over to the sub at 45hz. I have Klipschorns and an Epik Conquest subwoofer. In my rather large room the 45hz cut off sounds best. At 40hz the bass is lacking, at 50hz the bass begins to sound muddy. Once your set up, just sit back and and listen to music and movies and play with the crossover setting in your AV processor or receiver. Also listen at different volume levels. Crank up the volume and change the crossover settings on the fly. The perfect crossover point for your speakers and room will be easy to hear. Q.

Times do change. I'm now using the Epik Conquest subwoofer. An 18" driver in a big ported box. It's the best subwoofer that I've had, so far. It comes close, but it can't keep up with Klipschorns. Now there is the Tuba HT horn loated sub. The 36" wide one should be worth a try. There is also Danley Labs DTS-10. A tapped horn. This one has my attention.

What was your reason for selecting that driver, since Bill recommends using the Dayton DVC 385-88? Q

What driver do you have in it? Q.

I think that John was talking about measuring the resistance of the individual drivers. An 8 ohm driver will measure about 6 ohms, and a 16 ohm driver will measure about 11 ohms. A combination of drivers and networks in a speaker could measure anything. You would have to ask the manufacture what the dc resistance of the whole speaker should measure. I bought a pair of Altec 288-16K midrange drivers a while back when I was doing some experimenting. Before I tried them I measured the resistance. One measured 11 ohms and the other 6 ohms. This told me that someone replaced the diaphragm in the 6 ohm one with a 8 ohm diaphragm. I opened it up and found an 8 ohm diaphragm. Did the seller know this? I don't know. I need to call Bill at Great Plains Audio and order a 16 ohm diaphragm, so I can sell them as a pair. If I remember correctly, Trey once told me that the LaScala should measure around 3.4 ohms. I used this when I was buying LaScalas as a quick test.

I was thnking about this last night. I have a lot of VHS family videos and I want to put them on DVD's. Maybe we should be thinking about putting them on Blu-ray???

I bought the WD65835 from best buy last Dec., and I had the Geek Squad come out and calibrate it. Couldn't be happier with DLP. It has a better picture then my two ( also new) Samsung LCD's.

Good observation, or imagination. I never looked at them that way before.

I hope that you really don't think that I'm making fun of you with the K402 horn. I'm just interested in the bass horn at this time. If I din't have my tops, I would be going with the K402.

This is the best that I can do. My room is dark, I brought in some extra lighting to help, but now you can see that I should have done some dusting first. I included a few pics of the center channel, so you can see the 290 driver and the horn not in an inclosure. The horn inclosure isn't mounted on a flat surrface ( baffle) like Altec did with it's smaller horns that they used for their home speaker systems. This horn was mainly used in auditoriums, stadiums, and concert halls. I should do something to make the tweeter look better, but It's my room and hardly anyone but me uses it. I'm also always changing things, it's just been a while. The Jub bass horns may make me change again. http://i31.tinypic.com/99f7rm.jpg

Just a side comment.... the main reason Klipsch sells the Jubilee as a 3-way is to maximize its output for cinema/stage type use. I can only ask that you trust me when I tell you that the Jubilee in the 2-way format is WAYYYYYYYYYYYYYYYY enough for any residential use. Especially if you want to keep your hearing intact. In my opinion, one benefit of staying 2-way is you drop a crossover point and when all this engineering comes together, what you find (or what I found to be more specific), My Khorns needed a bit of room for the sound to come together as a singular wave front (I also had the 2404 tweet and Al K's extreme slope crossovers) At 30' away, my Khorns were liquidity personified but when I was in the same room with them (open floor plan) I could discern differences among the drivers. With the Jubilees being 2-way, using some signal alignment on the drivers, my Jubilees sound as good in the room as they do 30' away. Put differently, they sound better in the room than my Khorns did in the same room. True, true, true. I agree with everything that you have to say. I also know the the Jubilee bass horn was designed to go higher just for that reason. The Jubilee bass horn may be different, but I never heard one that sounded as good as a midrange horn upwards of 350 Hz. That is the reason I want a to use my top hat. I'm going to first try crossing over at 400 Hz. Tell me that I'm not an old school Klipschorn guy. I have a combined kitchen and family room now. The family room is 17 x 30 with a 42" high bar top wall between it and the 17 x 20 kitchen. I always notice how good the Klipschorns sound from 30 to 50 feet away.

As has been said...what I found so interesting about doing that (via using the defeat buttons on my Dx) is just how sucky both parts sound on their own. Had I heard either half on its own I would have NEVER felt it could be part of a nice sounding system. I still get impressed when I cut them out to listen to a single horn. This also had me wondering.... for someone like Roy who's been around horns for a few weeks, can he hear two different single horns and without the rest of the spectrum, know by ear that one is a decent sounding horn relative to the other. Does that make sense? It is amazing! I used to keep one room set up with a stock Klipschorn in one corner to use as my reference speaker. I would A/B other bass horns, midrange horns and drivers againts it. I also used to listen to the midrange horns and drivers alone to try to narrow down what I was hearing. I would call my kids into the room when I wanted another opinion. When I singled out a driver or horn they would hate it and tell me how crappy they sounded.

I'll take some new pictures and post them for you.
