Speaker Set Up Issue

717 Views 11 Replies 7 Participants Last post by  BARUN
Hello Everybody,

I am a complete newbee to the forum and to the world of Audiophiles. I am trying to set up the speakers and the subwoofer to the right level but not succeding. There is something amiss. For eg if my volume is set at -20 which is kind of high (volume range is -80db to 0 db) it does not seem to be loud at all.

I give all the details that I thought will help you decide the right configuration for my speakers, subwoofers, crossover frequency and LFE.

These are the current settings and details that may be required.

Speaker config check

Subwoofer - Yes

Crossover frequency - 120 Hz

I will be grateful if you let me know what should be the ideal config or close to ideal. Please do not ask me to buy a SPL meter,audio CD's and do all the measurements. Right now it is beyond me - I have crossed the budget and also the amount of time I have spent on these things. I also note that my set of speakers are not the best and is 6.1 instead of 7.1 - budget restraint.

Will await eagerly for the comments and the config.

I know you don't want to hear it, but you can't properly set up your speakers and your system unless you at least get an SPL. Adding a DVD like AVIA would help too (though it helps more with video calibrations than with audio calibrations). As far as I am concerned, you are asking for the impossible.
Try to borrow an SPL meter and get Avia from Netflix.
Does the manual describe speaker setup/testing/options?

Most have test tones and allow independant settings for each speaker to adjust.

Boost the volumes for front/center/rear. That will correlate to the 'master' volume.
At a minimum:

Set distance to actual, for all speakers(Speaker to Ears).

Set crossover to 80Hz, 100Hz max

Set all volumes except the sub using test tones

Set sub volume based on listening to music that you know, not the test tones.

Good Luck. You have a pretty big area to "fill" with not so big speakers.

-20 on the master volume control is not loud at all on my receiver either. Depending on the source material, i can go up well into the single digits before it gets too loud. If you have a large room, that'll only make matters worse in that regard. It's ok to crank it up past -20. Is that not acceptable to you for some reason? I'm not sure what the problem is...?
Hi Gertjan,

Thanks for the reply. The volume level can be from -80 to 0.At 20 it is 3/4 the Max volume and yet it is not so loud at all. I obviously think that there is something wrong with the settings.

I also wanted to have a deeper bass which I am not getting at the setting level that I have although I am getting the higher frequencies.

From what i've been told, -20 on that scale is NOT 3/4 of the max volume. It's a dB scale,and it's a log scale. Anyway, i would not expect -20 to be loud in your size room.

Deeper bass, or louder bass? You're talking about setting level, which refers to loudness. If you want deeper bass, well, that means you need a better sub or tune your existing one. If it's loudness, you need to calibrate the speakers properly...?
Sounds like a pretty big room for some HTIB speakers to fill including your expectations.

Setup of the speakers and the room itself can make it all worthwhile tho....is the room carpeted, furniture with tables, plants, etc? Are the speakers setup in an equilateral triangle: meaning the distance between the left and right mains is the distance between you and the two mains.

Also I wanted to ask about the level set for the subwoofer....-10.5? What is the reason for this since all the rest of the speakers are around 0? Set the gain on the subwoofer itself around half and go back to the receiver and calibrate that again. No reason that you shouldnt have that level at +2/3.....check it out.
Hi Yosh70,

I agree the speakers are small comapred to the room. There are two reasons behind this - firstly my budget and secondly I am live in an appartment - can't play it loud.

The room is carpeted and has furniture and plants. The subwoofer level -10.5 has been set by the Auto EQ set up. I have since increased at around +2.0 db.

Thank you very much,

So does it sound more to your liking now?
Yes it is close to my liking. I would iseally prefer to have more bass but cannot do that in an appartment. Hope to move in six months time.
