Possible ways to equalize my Hi-Fi?

[Anonymous]

Gary Mardell:OK, so you're getting the effect on all songs. Then it's the room.I'm not sure if I can find a calculator on my PC, but I'm sure there'll be one online somewhere.It's the C, so around 70Hz, give or take.A parametric equaliser allows you to choose a frequency point around which you cut, or boost. Cutting is the best thing to do. It will also allow you to choose the width of frequencies across whihc you apply the cut, and finally, by how much you cut it.Try the walking around trick. There might be a simpler solution than getting into room correction.EDIT: Ohh, just found a calculator. What's the Height, Width, and Depth of your room?

W: 2.5m

D: 3.5m

H: 2.55m

there is, read my post on the first page. sorry, but it's what i believe - it sounds like you have the exact problem i had. it's your speaker/room interaction. one of them has to change.

Something in your house is resonating with that frequency. Find it!

I'm quite surprised.

Are there no proper systems for properly equalizing a high fidelity playback system?

Obviously many of our listening rooms are less than perfect acoustically. So do people just resort to buying bass shy components? Crazyness.

I have experimented with bunging the speaker ports a lot. I had them bunged for a few months, just to get rid of that spike, but what it actually did was reduce most all bass frequencies. Then one day I took them out and realized what I had done. That is, miss out on good clean bass for ages, just because of the spike in the bass, and as I am happy with everything about the sound apart from that notes interaction with the room, I want to solve it.

There must be something, apart from buy a graphic equalizer that I'll have to find space for, configure myself, and potentially ruin the sound anyway.

Not usually used for 2-channel systems, but all high end home theater, and pro systems will have room correction in. These are usually multi-band units designed to correct the whole system with respect to the room.

i think its probably room related then - can you post us a picture of your room?

like I said .... dump the sub ... dump half of the furniture in your room and you will be fine ... sounds like your room is not ideal (especially if you cannot move your speakers more than 30cm due to furniture being in the way)

or alternatively, get yourself a decent pair of headphones ... problem solved

its not the sub - he said with it off the issues is still there - stop putting down subs they are fantastic for two channel systems when set up correctly! much prefer my standmounts and sub to any floorstanders i have ever used

I know it's room related 😉

Here's a pic *waits for attack*

need a pic the other way facing away from stereo! does closing the curtain make any difference also someone on here can't remember who bought two noise isolation foam squares to place behind the speakers could be an easy thing to try but radiator may be an issue

a bit tight and not much you can do at present ... keep what you have and get some decent headphones for the meantime till you have a larger listening room

 

[matengawhat]

also sub next to wardrobe (empty space )and cupboard under fish tank is prob not best idea - have you tried between speakers and rack

i know they say put subs is corners but they usually mean if you have two solid walls not empty spaces
whats to the left of the left speaker?

The sub - if that is it in the RH corner - appears to be between the aquarium stand (hollow I assume) and a wardrobe/cupboard unit.

I would expect that arrangement to resonate.

I am guessing that the LH B&W speaker is very near a room corner (although we can't see it) from the dimensions you gave us.

Yeah, couldn't agree more. Could be something as simple as tightening the screws on the hi-fi rack.

That's reminded me, he may benefit from having the cones on the speaker fastened - if they haven't been checked, it's very noticable on the lowest of frequencies.

Exaclty.

NOW. I read your post, and you are right. Except for the fact that either the room or speakers have to change. The problem lies around 70Hz.

I need to equalize. Full stop.

Still shocked no-one appears to have considered this, p*ssing thousands on different hi-fi components just to solve their problems. (Or just avoiding anything but the leanest components).

My point is if you equalize your system, you have more choice in what components you can use - i.e. the ones you like the sound of, without worrying (too much) about the room.

Just checked the spec on the B&Ws. They use 1st order crossovers and one of the problems of those is that you do get some lobing (sp). Their power response into the room will not be even so this could magnify the problem, especially with regard to the listening position.

Their frequency response curve doesn't seem to show that this region is 'humped-up' at all, so it doesn't look like a fundamental speaker issue.

chebby good answer LOL

like I said, a bit controversial, but I personally do not believe in adding a sub to a hifi system ... just my own preference ... that's why I have speakers that have decent bass

Okay stop.

I am not changing ANYTHING IN THE ROOM.

I posted asking about EQUALIZATION.

Everything else is irelevant.

That's right. Read my previous posts properly.

see i would say your speakers were bass light and didn't offer a full frequency range and you would be amazed at the amount your missing!

in my opinion, no matter what you do, you will still have the same problem in that room .... unless you get headphones (or get rid of the bed and sleep in the cupboard)

 

[chebby]

Ok. Well myself and others have already suggested you get an equaliser yet you continue to be stroppy about it.

You want/need an equaliser.

So get an equaliser.

OK, fine. Despite all the advice you know better. Now go buy an equalizer such as those you have been pointed to, and quit your whining.

Sorry, was that a bit blunt?

 

[matengawhat]

what's the point in asking for help then - the normal solution to issues like this is something simple without having to spend money on anything else and getting the best out of what you have - placement of system in your room is the main issue. Even the best exotic system set up badly will sound rubbish - speakers are very sensative to placement

i would say your sub is def in the wrong place!

By adding any kind of equliastion you are just masking the problem and will find that you will upset the whole frequency range and not just that of your target area
