Trying to improve my room acoustics

[RobinKidderminster]

True True Blue. A couple of obvious but also interesting suggestions. Triple linings to curtains maybe. Never thought about coving..Mmmmmm

interesting replies. overdose i wouldnt say that there isnt any bass present as there is , its just its impact could perhaps be better. for example my room at uni i use a subwoofer and it integrates really well into the system the bass sounds nice and flat, but i think thats due to heavy furninshing in the room eg a double bed right next to the sub. so robin maybe correct in suggesting bass traps.

my kit list is as follows: monitor audio rs6, sugden cd21 series 2 cdp, musical fidelity a5 preamp and 550k supercharger power amps. i know i am not gettin the best sound possible as when i puirchased my a5 preamp i demoed it with the sme 550k superchargers and my small bookself speakers (mission m71) and was stuned by the sound quality. only difference was he had a pretty high end cdp (although mine is of pretty gd standard to).

i will upload pictures this wkend as i will be bak home. then you guys can see the layout etc .

i heard isolating the sub will make the bass better defined etc. in the bass department i believe the bass needs to be flatter tbh, perhaps a bit better defined. i dont really get bass boom tbh. iv played around with sub placement a bit as overdose said you can get null bass spots which i identified to so i moved the position from there pretty quickly.

A very interesting article interviewing Ken Ishiwata of Marantz fame, visited their Eindhoven HQ and had a look at the main listening room, designed by himself.

Asked where he thought many audiophiles go wrong he stated that often, rooms are over-damped rather than the other way round, which, in his opinion, robs music of life.

Interesting and perhaps worth remembering ...

regards

Looking at Kens item here I would suggest his ideal room is treated far far more than any of forumites lounges. Maybe he was havin' a laugh?

Thanks native for some support Are u using bass traps too? I guess the word 'trap' leads to misunderstanding. The physics is easily understood but I recon WHF miss a trick in not making much mention.

Cheers

I use to use them, but not anymore. I have moved house since then. Am now on solid floor. I used mine in a studio enviroment before. I was not gettin the right kind of bass.. The bass was just abuot there but really lumpy kind of bass. After treatment all that vinished. The bass became full rounded & deep.

Did you try the sub setup according to any of the links I posted? Did you try it with any test tones?

If the sub hasn't been set up properly, any attempts at rectifying the problem will be grasping at straws. You never know, you might get lucky, but as with most problems, a steady and methodical approach works best.

Good links od

It's how I set my sub up.

Software takes the guesswork out of the equation, but was a step too far for me. I wanted to get the job done quickly and only had immediate access to the test tones.

 

[RobinKidderminster]

My ms sub is supplied with test tone cd and a microphone which does the eq nicely tho only around 2 frequencies. Regrettably this won't aid the op sorry.

 

[krish123]

guess i need to check out the freq my sub is set to. i also have a pass filter setting on my sub, what is this used for ?

 

[RobinKidderminster]

Simple answer there. Set sub to max probs around 120hz or higher and set xover in amp setup. Start at 80hz & speakers set to small. Experiment from there.

 

[krish123]

i dont have a reciever, i have a pre- power combination.

 

[krish123]

hi guys these are the images i promised hope this works. also checked my sub and it is set the ow pass filter is set to out, if i change it to in i can adjust the freq which changes the output of the sub.

 

[krish123]

i dont think those links work, not sure wat i have done wrong. i just opened the images in ie exporer and copied the html into the insert image tab.

 

[RobinKidderminster]

Nope. Try uploading to photobucket

i now have all the images on photobucket, my username is dhokes123.

Sorry not to explain more fully. You now need to copy the link using the 'add photo' link.

Sucess! Nice room tho not sure where your listening position is. With so little furnishings I think room treatment would make a huge difference. Depends how far u r prepares to go. Only my opinion ofcourse. Good luck

my sub is connected via a splitter on my preamp. as for the cut off wen i adjust the knob it doesnt seem to have any difference. my sub does have a phase of either 0 or 180, currently set to 0. What cut off freq should i have the sub set to?

What exactly is this "splitter"? Just a cable that splits in two? Doesn't sound like the best way to be adding in a sub.

The 0-180, I think, relates to the phase. My understanding (and I may be wrong) is that it can be useful when bass from reflections or other sources cancels out or causes an excess of bass. In my room, the bass is there but thin when the setting is at one end, and it is full and beefy (in a good way) at the other end. Might be worth faffing around with that.

 

[krish123]

thnx robin, yes i agree to however not really in position to do much :/.

the splitter s exactly how u say it has two rca inputs going to one input. is there any other way i can connect my sub up as id rather have each channel only for left and right speaker.

 

[krish123]

also just to let uno a 32inch tv will be going in the area just above the middle of the two speakers, at the same time i will get a few photos up do u think this will help? how exactly do photos on the walla improve the acoustics?

also is it worth putting some rock wool behind each of the picture frames?
