Thanks for all your posts everyone, its a fun, and certainly controversial subject. I have only scratched the surface about this subject and honestly have only given you my starting point to setting up speakers. I find this works with a majority of the speakers out there. I absolutely agree Arthur and a point I did'nt address (because I didnt want to make my first post to darn long that no one would read it lol) that anytime you change anything in the system, you may and most likely will have to make small ajustments to your speaker position. Toe in is another subject I didnt touch as well. breefly It depends on the speakers, distance from side walls. Yes a majority of speakers bennefit from atleast slight toe in. For example I found that thiels to me sounded best straight on, one because there tweeters sound more natural off axis, they tend to be a little hot on axis. They also sound more open and soundstage better. Where as Aerial Acoustics sound better toed in quite a bit. Another part of this subject I also really wanted to touch base on that is so important, almost deserves its own tread is perspective. I always ask or determine how my customers like to listen to live music when they go to concerts. For instance I have a friend/slash customer whom I spend many years designing and setting up his system, likes to hear his music as if he's sitting front row center at a concert. Well maybe not quite that close lol but a closer perspective than I do. Where I like to sit more mid field where I like to be drawn into the music. There is no wrong or right here its just personal preferance, But that does effect speaker placement, type of speaker, and electronics.
Bigtee thats a need little trick with the sliders I usually move my speakers around without spikes to get them close then fine tune it with the spikes on. We all know how hard that is lol.
James: Do you find that this resonance happens in many other recording, not just the one with the standup bass ? I'm thinking its ether your hearing a resonance in the room, or its in the roecording ether the instrument or the room they recorded it in. Room node, or standing waves are quite honestly very hard to get rid of. I dont like introducing anything electronic into the chain to address this issue, but I have tried a few with some decent results without totally screwing up the fidelity of the system. passively is a whole other subject but I will touch it breefly. I have found its really impossible to effect bass to any real degree maybe a 1/2 to 1 db at max or so with acoustical treatment. Now helmholtz resonators build into the walls and tuned to specific frequencys will work to more significant degree. So that is something you can try and experiment with if you find that is your issue. I would try a wide range of recording a determine if its your room, or speakers, or the recording. Then go from there, Let me know.
So Im thinking its the room resonance nodes which quite honestly will be difficult to address and most of put up with it to some degree, unless you have unlimited budget, time, and no girl friend or wife lol.
Paul: Hey some good points you've brought up. I have poked my head around audiogon for years but really never did much or say much until now. At the moment Im not working for a store, I am independent and doing my own thing. I dont have a store, its strickly referal only. I would love nothing more than to have my own shop someday its just not in the cards right now. Maybe someday.
My name is Kevin LaTour so its not Anonymous anymore lol if that makes you feel more comfortable. I've worked for Christopher Hansens in Beverly hills for years when it was around and another hi end store that I wont mention (for respect of my friend and owner of the store, incase he does'nt agree with my philosophys lol) But we specialized in tube electronics which I am a big fan of and analog (turntables) play back systems. I go all over the country setting up turntables and systems.
Anyway yes you bring up some good points. Yes many manufactures design and tune there speakers at certain distances from the walls. infact linn speakers are designed and tuned to be right against the walls. Now its my understanding that Linn doesnt believe in soundstaging. Now granted tonal balance should be number one priority, but for me soundstaging is the fun part, and im sorry I know and believe it exists. Maybe not in every recording but all that are recorded with minimal miking, live straight to tape. Many of your Classical and Jazz recording are done this way. Hey I can even hear if the instruments are behind the microphones or infront of them. Talk about surround sound lol. Yes most of the older horn speakers like a Klipsh horn were tuned and designed against the walls. La scalla's were my favorites in the days. Haven't heard them in years lol might be fun. I use a small pair of book shelf speakers now (cause the girl friend lol) and yes I have them almost in the middle of the room when I do serious listening. ( I have marks on the floors that I can just pull them out when i want to listen to music).
Yes all rooms have nodes and standing waves, and again unless you have a big budget, dedicated room, then realisticly we may have to put up with a slightly less than ideal situation. I have concreate floors with a large area rug, and a couch. The nice thing is, believe it or not I have NO PARALLEL WALLS in my living room. I know its hard to believe but true lol cool ha ? Sonically its a pretty good sounding room.
Again I feel placing your speakers without room treatment is the way to go because, one I find its very hard to place your speakers. I can hear the room treatment. You dont know the end placement of the speaker so they may need to be moved as well. I find when I have the speakers in the correct place I find I hear less of the issues with the room, which in turn means less room treatment, which in my book is a good thing !
I look forward to more on this subject and thanks for the posts guys. Good luck and happy listening. Kevin
