Thanks @mustang guy oddly enough 120 is where I set them some time ago after trying different things. Even a blind squirrel finds an acorn every now and then. I will move it back. Now about this crazy idea to make a 6-foot tall tube subwoofer with a bunch of drivers, is that worth thinking about or just nutty? I read about dual-driver "push-pull" systems but have no idea how they are set up except that the drivers are pointed in opposite directions. Must be some sort of timing involved. But what if we had a tube with 2 drivers pointed each way, or even 3 to be completely wacko. Would that work? And I am just wondering, not to say I would not try.

I tried listening to just one speaker and going back and forth between the RC-7 and the modified RF-5. I could not hear a difference, so for my purposes, yes.

I have an Integra DTR-50.6 that I bought for $200 and an Outlaw 7700 amp. I am really struggling to learn the Integra, but I will get there.

Thanks @CECAA850. They actually are on stands that stick out to the sides, and I bet if I took off the back ones, it would do just that. Thanks for the idea. I will try it and post a picture.

@richieb I was being mostly silly when I said that, but Kansas is a strange place. My wife and I lived together a a few years without being married, and half the landlords would not rent to us because we were living in sin. It was just not the place for us. But I am a Jayhawk and happy to be one. We were there in 1987 when the basketball team won the national championship. There were some good times, but I gotta be by the ocean. And I will say that I met many wonderful people in Kansas. It is the place I hate, not the people.

Congrats. How did the uShip ting work for you?

Could you orient a CF-4 sideways or would that mess things up?

Thanks @Frankenstein I may contact him If I switch to KLF, would need some of those.

@CECAA850 the chairs are about 6 inches tall.and the tweeters are about 4 inches over my head so[ting on the couch. It was an experiment after I put the rug in. No idea where it will end up but the rug swallowed more sound than I expected.

The effect in my room is to produce what I would call effortless sound. It fills the room comfortably but does not call attention to itself. Some systems seem overpowered or overwhelming to me. I guess I would say that this gives great sound that you hear but don't notice.

I went to college and law School in Kansas and share your aversion to going there. My wife and I left the day after we graduated from law school in 1991 and I have never been back. We actually pulled over when we crossed the Colorado border and flipped off the entire state. Arkansas is actually fine but it has Kansas in its name.

Thanks @mustang guy that made perfect sense. So subwoofer cutoff at 80 and subwoofer placement based on subwoofer not speaker considerations? You really made this clear. Thanks.

Every since I saw the CF-4, I knew I wanted one. That was a long time ago, and while I have had some close calls with real ones and lucky escapes from scammers, I still do not have one to my name. I am in Seattle, which seems to be at least a thousand miles away from any other member here. But if you are distant and willing to work with me, I can arrange shipping. If you have one now or in five years that you want to sell, let me know, and I will be a buyer.

This just made me realize that in all my searching for an RF-7 i, I have never encountered a black one. I wonder how many they made.

For CF-3 that have been this well cared for and upgraded by someone who knows what he is doing, these are a bargain. If it were not for my aversion to entering Arkansas I might plan a road trip. Someone is going to get some very special speakers at a very good price.

At long last, we have a 5.1 and even a 7.1 system in place that makes sense. Leading off in the center is our revered RC-7, perhaps the finest speaker ever made. And for the Left and Right speakers, we have two more RC-7. Wait, you say, that is either not possible or ridiculous. My good friend @jjptkd had a pair of RF-7 and a pair of RC-7. So in delicate surgery that lasted until the night he transplanted the tweeters and crossovers from the RC-7 into the RF-5, careful to reorient the tweeters for their new home. And then to avoid a tragic loss, he transplanted the tweeters and crossovers from the RF-5 into the RC-7. And all three for $800. A bargain as far as I am concerned. And those two mutant RC-7 now stand sentinel as my surrounds. I still have a pair of RS-7 and am not sure how the surround thing gets worked out;. I cannot get anything to play all 7 speakers even with 7.1 content, so I must just being doing something wrong with the receiver. It is very confusing, and the manual is worst piece of writing I have encountered in my life. It has network, and I hooked it up, but is has no option for a WSA passcode. Stupidest thing I have seen in my life. But back to joyous times. I am using a long subwoofer, my trusty PB2 Plus, but I have seen the light, and I want something newer. In fact, I have been told that a blind quadriplegic monkey could make a killer subwoofer in half an hour using only items found in its pen. I really like the round ones, so now I am off to the races with that. I really wanted that B4 Plus that weighs 200 pounds and have 4 woofers, but I have an idea. Maybe if I made a tube subwoofer 6 feet tall, I could get 6 or even woofers in it. Makes sense to me. So here it is. I put the RF-5 on small chairs because I think they sound better raised. And these are the wonderful surrounds. It all feels so great, and yet, something is calling to me.

Thanks for the post about the KLF-30. I found a shipper for $150 and sent the guy a note. Why I wold go that after completing my system, I have no idea, but 2 pair of KLF-30 could only be fun.

The horns remain. I understand they are the same. The tweeters were removed from rc7 and reoriented for vertical speaker and the rc7 crossovers for the tweeter were switched too. Both speakers have 2 8 inch woofers and a tweeter. So the rf5 should be identical to the rc7 except that the rc7 tweeter is in the middle and the rf5 tweeter is at the top. I now have 2 rc7 with rf5 tweeters a d crossovers as surrounds. On big happy 8 inch woofers family. My overall sense of it is one big undifferentiated field of sound. Nothing is stronger or weaker

To be clear, I am looking for a driver that produces sound not just noise. When I have my bypass on, it is set to 120Hz because I prefer for the bass to extend into substantive sound. I often turn it off, but it is not clear to me if I actually get getting sound up to the 250 or so Hz that the PB2 Plus can handle. It would be great to find something that went up to 360 like the SVS PB16, but I really do not know what the sound quality would be like up there.

Hmm, Massey. You know if you boxed it, up, all you would have to do is drop it by your local FedEx Office. Roadie.com says they will ship "fits in the front seat of a care from Detroit to Seattle for $101. No boxing needed really if it would fit. Do you have measurements and weight (75 pounds I think). And would you do that? If not, I understand completely. Not trying to twist your arm.. I'm sure one will pop up in Seattle one of these decades.

Ha ha I thought I was joking about more than two. SO I guess the next questions are which diameter has the best drivers and how much bigger than the driver the tube should be. I was assuming that it would be one size up, 20 an 18 inch tube for a 15 inch driver, 20-18, 22-21. Parts Express has 22 each of 10" and 12" but only 8 for 15" and 18" and only 1 for 21". Maybe Jeff at JTR would send me a few of his.

I like the SVS cylinder subwoofers, and from what I have read, performance is the same as cubes. I have been told that the round concrete forms are ideal to make them, and I was hoping that someone could make a suggestion as to the preferred thickness of the material. Sonotube has diameters from 6 to 60 inches. The thickness of the materials depends on the length of the tube. So a 16 inch diameter tube ranges from .155 inches to 1.034 inches. A 20 inch tube ranges from .242 to 1.616 inches, and a 22 inch ranges from .293 to 1.956 inches. Those are for lengths of 3 feet and 20 feet. These are made from Cardboard, so my inclination would be to get the thickest material I could and have a 20 foot tube cut into 6 3.33 foot lengths or 6 2.83 foot lengths. Of course then I would have to make a lot of subwoofers so as not to waste material. But if two subwoofers is good, then seven has to be great, right?

Yeah if I were going to Atmos, the sound would come from on high, not on low. The idea of magically bouncing sound off my ceiling has no attraction. Then again, ceiling speakers don't either. Now this slanted BHT from JTR, it interests me very much http://jtrspeakers.com/slanted-8ht.html. No idea if the price drop from $1,798 to $899 is real or not.

OK I reached out to him to see if he would ship. It looks weird enough to interest me.

How far away from the corner itself? I assume yo would not actually put it next to the walls. These are far more recent than my PB2 Plus so maybe age is not an issue.
