Evolvo

I have a pair of la scalas on the long wall of a 16' X 11' Room with 7' high ceilings. The speakers are about 12' apart and I sit about 1 feet from the 11' wall so if you factor in the 2' of the la scalas I'm about 8' ft away from the the center of both speakers. Should I sell these and go with some Heresies or Quartest? I'm simply wondering can speakers be too big for the room. I hate to sell them. I have a pair of Cornwalls those might be too big too, but they have less depth. Also what are your thoughts on placement in such a room, should speakers be closer together given the distance I sit back. I'm so close that unless I'm in the center of the room I can hear the speakers individually. Please let me know your thoughts thanks.

So if this little voice coil is like a fire cracker taped to an engine block then why does my walls and duct work rumble and shake. If u were right nothing should be moving. Apparently that fire cracker has more power than ur giving it credit for. So in theory the same vibrations that make my floors shake which weigh thousands of pounds could be make my minuscule stands vibrate which in turn can cause my speakers to vibrate, creating distortion and "sub harmonic transverse tonal imbalances", ok I might have made that last quote up from a movie, Lol

We go back full circle to people giving advice who don't seem to have any understanding of physics. Speakers work in the first place by creating a force between the voice coil and magnet. Because the mass of the voice coil and cone is so small compared to the speaker frame/magnet and speaker structure, almost all the force is translated into cone movement. (The rest is lost in friction and heat.) To be able to cause the loudspeaker to rock (especially at woofer frequencies) wouild require a huge electronmagnet and thousands of watts of energy. Can an exploding firecracker taped to the side of an engine block cause it to move? Same principle and about the same differential. Sure, having a stable structure is a good idea. Who wants to tip a Cornwall over on their foot or on a kid? But this concept of a 2 ounce voice coil and cone making a 60 pound speaker move is enough to make Sir Isaac roll over in his grave. I'm not giving advise I was giving my thoughts on what I thought might be happening to get opinions. Ur just another guy who enjoys arguing. I think ur wrong anyway. How could the stability of the structure it's sitting on not make even a minute differences. Places sell hundred dollars stands to help with resonances and quality of bass and sound. Speaker cabs are built thick and strong for a reason so they don't resonate so much. So how could a wobbly stand not matter. I'm not saying its major but there could be potentially audible effect at some level. We reinforce cabs, why not stands. Many people including other high level audio guys would disagree. I know u guys like arguing so I hope u take the bait and indulge heavily. I honestly could care less, most of audio is a bunch of guys pretending to hear things they can't anyway. I'm probably guilty sometimes but atleast I can admit it. Lol if it makes u feel good build it. If u think it sounds better buy it.

Holyshiz!!! Moved them to the corner and no more null the bass is in the center and the null is on the outside. This sounds fantastic. I've should have known this but didn't realize it would be this massive of a difference. Unreal bass. If I put them on the floor I'd probably blow my house up. Thanks Favog and everyone else.

Thanks for the helpful advice from all. So I've finished the stands and they are probably about 23" tall and filled with 100# of sand each (they still have space for another 25# each. I do feel like the bass and sound overall has tightened up, but the bass null I had in the middle of the room got bigger. It literally almost seems like there is no bass in the middle of the room and as you go towards the walls it seems like there is a 10 - 12 db increase maybe more. I think before the stands were about 2" lower and this maybe the difference. So my question is what can I do to get more even bass or more bass to the middle of the room. My room is 23 X 13 and the speakers are on the smaller of the sides of the wall. The speakers are 2' from the back of the wall and up against the side walls towed in about 15 degrees. My seating position is probably exactly in the middle of the room. I have 2 2x4 bass traps on the walls horizontal to my listening position at head height and Huge one in one of the back corners of the room that is literally 5' wide and 7' tall all made out of Insulation I believe R39. I think moving them back towards the wall would create more bass, but would it help with the null? Would lowering the stands a bit lower the nulls? What about bass traps, if so where should I put the traps, possibly back wall or behind speakers. Any help would be appreciated. Thanks.

Cask05 You essentially disagree with my logic by telling me that I've answered my question in a way that I wanted it answered, then you go edit your posting to essentially agree with what I said, which is it? My whole point was that I though having bigger sturdier stands would benefit me and in your Edited post above you concur by saying a bigger stand with more space underneath it would help to increase bass. So I'm not sure why your saying I'm doing what I want to hear. How am I suppose to know what right anyway with all you guys arguing, one person saying it does and another it doesn't. So it simply comes down to do I think having wobbly stands is bad?, yes. Do I know if it will help with bass? who knows can't get a straight answer, so build them and hope for the best. I stated in my response that I didn't care ultimately whether it created a difference in sound, I just simply wanted to know if did it as I wanted better stands regardless. So you were wrong before you adjusted your answer and thought more about what you were saying. I think some of you guys like arguing so much that you answer before you even have a chance to fully come up with a good answer. You also argue so much that you come in my listing and hijack it and start talking about speakers on floors when I never asked anyone whether I should put speakers on the floor. If you want to argue go somewhere else. I need real assistance not flip flopping answers, just cause you want so badly to disprove someone.

I appreciate the comments although I don't care that I lose bass because they are higher off the ground as I can't help that given I have 2 tier seating in my movie theater. To be perfectly honest the bass I get is ridiculous and shakes my whole house. I simply care whether I could be getting more clarity out of the speakers at the height I have them at with more solid stands. At this point I surmise that my stands probably should be sturdier and weigh close to or more than my speakers so I've already started the process of building more rigid stands as I really can't go wrong considering it will only cost me $40 to build box stands and fill them with sand. As someone suggested I would think think that the energy from the woofer is being used to create speaker sway rather than bass, so I likely might be losing something. Even if I'm not it still feels good to have sturdy solid stands. For those of you who have standards on placement I say put them where they sound best and try all positions. Given my situation there is no way my speakers would sound better on the ground as it would be like listening to speakers standing up. If you think speakers sound better hanging from the ceiling go for it and try it out, if sounds better than other positions you've tried then you've got a winner. Everyone seems to have the best possible solution. The best possible solution is the one that sounds the best after you have tried all positions, all these so called rules of placement are simply guides and estimations to assist in proper placement. Thanks.

I have a pair of klipsch Cornwalls that are on dinky stands that I made out of two pieces of MDF and 2 2x4 legs. They are probably about 18" high and weigh 12 pounds and the speakers pretty much wobble if you give them a little nudge, they are not so wobbly they could potentially fall over, nor do you see them move when playing music. The reason I have them on stands is because I have a theater with a second row that is elevated and that is where I sit. My question is am I losing anything from having the speakers on crappy stands that wobble? Could I potentially be losing highs or bass because of the wobble? I read that lots of people who have bookshelf's will fill their stands with sand to tighten up the sound. So I'm wondering if I would benefit from building some speakers stands that are essentially a huge box filled with sand. Or are the Cornwalls so powerful that they can just perform no matter what they sit on?

I didn't take off my whole back but i will cause it appears that it is hooked up different than yours because I notice 2 wires on mine going to the negative terminal.

Pic 2

Thanks this is exactly what I need but I can't tell if the pic is upside down or not. I have included pics of mine. Also I can't see clearly were the wires are connected to the fuse. Could you possible take a closer pic. I took a pic with mine unhooked how it was when I purchased them and how it looked after I hooked them up the way I assumed they should be. The terminals on the bottom of mine are the woofers connected and the unconnected top two are the HF section.

I opened up the crossover on the bass bin and noticed the hf speaker connectors were severed, I'm guessing to bi amp them. I just want to confirm how to solder them back together. Do I just simply run the negative to negative and positive to positive from the LF input to the HF input. There are other crossover components in there but I'm guessing all of that is soley for tha woofer.

So would it be ok to turn a type C into a type E crossover or would the 16ohm SP12B cause a problem with the type e. I have a pair of type C's and from reading the info, type E's are better because of a better frequency response. Bob said that the inductor was the same on both the type E and C so it seem it should not cause a problem, but he wasn't totally sure cause he never had a type C crossover and done the mod before. It seems as though some people think you would need the 8ohm eminence K-22 to work with the TYpe E. thanks.

I have a pair of heresies that I'm trying to make a bit nicer and I have already sanded down the old finish. I would like to know if anyone has any suggestions as far as refinishing them. I've heard some people say use 1/3 Walnut stain and 2/3 teak oil mixture. I was simply thinking of just using a Walnut stain and then using a coat of satin polyeurathane. So if you have any ideas of what I should use to stain and protect them as well as how many coats please let me know what you think.

Hello, I was wondering if there are any difference between a 1966 and a 1972 PWK H-700 Heresy? Are the drivers the same, the crossover and all the other components? Is one better than the other?

It's the sub my receiver is fine. I know something is wrong with the amp just wondering if it sounds like resistor or capacitor something easy to fix. Sub with all knobs up sounds decent at medium vol levels.

Yes it increases level of the sub. But not to maximum possible. If I turn the sub and receiver levels all the way up its almost listenable.

IS ANYONE OUT THERE

I have a klipsch sub 10 that works fine except the fact that it seems the sub is only playing at about 1/4 of it's normal volume. This is not a receiver crossover problem, this is specifically related to the amp. I'm not sure if maybe a capacitor or a resistor or something got fried or what, but it seems weird that I have to turn the volume all the way up to get 85db's. I've owned like 3 of these subs so I know there is something wrong with it. Maybe it could be the volume control is broken and it doesn't increase volume at the correct rate. Please help Thanks.

Another pair are available check out garage sale, they may go up on ebay soon.

Hey PSG you commented on one of my post at bill site. Anyway dude don't let your THT go for 2 cheap, with all the work you put in to it. For some reason people love paying business's to build them a sub par subwoofer, but when it comes to people building things and trying to make a little money they don't want to do it. They rather spend $3k to get something comparable from a buisiness ie SVS, HSU, than spend $1k to get something awesome which would save them money and make you money. This sub is easily worth $2k for what it offers and someone should be jumping on it. People this subwoofer is amazing and will likely kill a PB-13 Ultra or any klipsch subwoofer, or HSU. Buy this now, before it's too late. You won't believe the extension or output. Simply stunning this sub is.

I have a Cornwall II and it uses the K34 woofer and when I called Bob Crites he told me that the difference was that they are mounted differently. He said the version he sells was to be made to be mounted from the inside, so he could not help me. He never said whether they were the same specs or not. But today I called klipsch and they told me, you can use the k 33, because it is the same woofer. They said you just put the gasket on the outside of the speaker (bottom of woofer) and mount it from the outside. They said 34 was just to specify the mounting. So I was wondering why Bob Crites didn't say this to me and sell me one of his woofers? Is it because his gasket comes pre glued to the front of the woofer, so you can't put it in on the front of the speaker, or is klipsch reps telling me something wrong? Also just to verify the specs are the same on 34 and 33? Thanks.

I recently bought a pair of klipsch Cornwall II's and have come to find out after posting them at auction on Ebay that they ahve K-48's in them instead of K-33's so I'm wondering does this pose any kind of problems. Does this throw off the crossovers at all. Which Woofer is better? Does this severly devalue my Cornwalls? Also are the K-48 worth anything if I wanted to sale them and replace with 33's? Thanks.

saying no after crites said yes, pretty bold, but in all fairness yours came a minute later, so maybe you were still writing. LOL. Well that makes me feel alot better. Both have the tape over the inductor, with a piece of wood strapped to the top thats screwed in so that thing is going nowhere. Anyway Crites, I'm the guy who was asking you about shipping speakers overseas and if the magnets posed a problem. Those la scalas had no problems and made it safely to switzerland. Bob, I'm thinking of buying some new grill covers for my Cornwalls, so I was wondering how long after i put a order in will it ship. Thanks.

I just bought a pair of cornwalls and I was adjusting the woofer and noticed the crossovers looked like this. The caps on it say they are from japan and from what I understand klipsch speakers began to be manufactured overseas, sometime in the 80's. However these crossovers definately don't look like the ones on my old La Scalas which which were from 1997. The cornwalls I have were made in 1986. Thanks for the info. If they are not originals what is the likelyhood that who ever redid them didn't know what they were doing and that the sound could be off because of it. They do sound quite awesome, I have to say though.
