Home Cinema Setup

Those aren't holes they're speaker drivers. Some subwoofers have more than one port. Some are sealed box.

Generally though with -dB scale, you have to have it quite loud on that scale, nothing happens much until you reach -20dB.

I meant drivers i just couldn't think of the name :D. I don't understand how anyone could listen at reference levels without damaging either their hearing or speakers (in a house), or is 0 db the level in the cinema and thats why its so loud in a house?
 
Thanks for all the replies so far. To answer some questions my sources are my xbox and flac files on my phone played via bluetooth and I'm using a 2.0 setup. Couldn't feel or notice a ridge on one of the speaker cables to identify if it was positive or negative no, but will take another look when I get home. I did run some sort of setup but it only checked that the left and right speaker worked. I'll see if I can find a one that tests the levels etc.

Seems 50 volume is about normal based on some of the replies which is fine I'm just a newcomer to the world of home cinema and wasn't sure what to expect.
 
If you're using absolute volume then its pretty meaningless.

you should be using relative ( -80.5db to +18db) then when calibrated youd know that -30db on your amp is the same as -30db on somebody elses calibrate amp, and 0db is reference level.

does the amp not have auto phase ? regardless of that getting the cables the wrong way round wont affect the sound level

Not sound level but it will affect perceived volume since the sound won't appear to come from the speaker.

it absolutely would affect the sound level. With speakers out of phase you've got speakers working against eachother to cancel eachother out - it's going to have an affect on everything.

Forgot I had created this thread and to check on replies. Bumping ask more questions...

Why are you streaming flac via Bluetooth?

I have flac files on my phone and computer and I've since set it up so receiver plays flac files over the network directly from my computer upstairs. If I try to connect phone via usb on the front it doesn't detect my phone and sound comes from phone speakers. Seems receiver might not be compatible with Android devices as tested it with an iPhone and it worked.

That went completely above my head which takes me onto why I've bumped this thread. This receiver has tons of options that I've no idea what to do with. To start I can select the amp assign:

I have my two speakers connected as FL and FR but the only option for stereo is ZONE2 so have set it to that.

Next on the menu is scale:

How to know which is best setting?

I haven't done Audyssey setup as with only using a 2.0 setup in Stereo I wasn't sure if it was beneficial so just went down the manual setup route.

One of the options is for whether I have large or small speakers. Now I thought the 2020i's were small speakers as they're bookshelf ones rather than the tall free-standing ones that I've seen. Is this correct?

As you can see if I set them to small it automatically enables the subwoofer setting when I don't have one. If I disable the subwoofer it automatically changes the speaker type to large. What should I use?

The next option is levels:

The manual doesn't really explain this in great detail so again I'm not sure what to set them to. Am I best to leave them at default (0) or max the volume out?

I saw Crossover being mentioned in another thread which I why I went to take a look at what it was set to on mine. From the manual:

Based on the specs of the speaker and reading what it says below the table I have now set this to 60hz. Correct?

[*]Enclosure Type: 2-Way Reflex
[*]Bass Unit: 125m
[*]Treble Unit: 25mm
[*]Frequency Response: 64Hz - 22kHz
[*]Nominal Impedance: 6ohm
[*]Minimum Impedance: 4.0ohm
[*]Sensitivity: 88dB
[*]Crossover Frequency: 2.9kHz
[*]Dimensions H/D/W mm: 265 x 278 x 170
[*]Sold in: Pairs
[*]Weight: 6kg

One option I haven't listed above is Distance. I've set this to 2m as that's how far away the two sofa's either side of the TV are at their furthest point.

With how I have it set up, streaming flac files sound loud enough at around 35db. When I then go to stream Netflix etc I have to turn it right up to 50db to get what I feel is the same volume. Might just be normal due to Netflix streams being heavily compressed, I dunno. BluRays I have to turn right up too.

Will Bi-Wiring make any difference? I wasn't sure how to do it.

Thanks for any further help and suggestions as this is all a learning curve for me. Once I know everything is configured right I can be happy knowing I'm getting the best performance out of my setup.
 
"As you can see if I set them to small it automatically enables the subwoofer setting when I don't have one. If I disable the subwoofer it automatically changes the speaker type to large. What should I use?"

Small. Then buy a subwoofer.
If you set to large, that means full range is sent to your speakers, which are incapable of playing LFE + bass safetly.

As for levels, do the calibration as that sets them for you.#

No, you want to set the crossover higher than the speaker. For yours I'd set it to 80hz.
Distance is set by calibration as well.
Biwiring won't make a difference.

It doesn't matter which volume scale you use. Choose whichever one you prefer, negative scale or the other

Ok thanks. Useful info there for me to go on.
 
Also

"ones rather than the tall free-standing ones that I've seen"

Even those should be set to small. Unless your speakers have a frequency response of 20hz-20khz, and you have a monster amplifier, you should set them to small. With crossover setting that is suitable.

Even my speakers, which have 3 x 8" drivers, which are "almost" full range, but not quite (36hz) and having 300W per channel, should be set to small. No lower than 40hz. Can be set to "large" when listening to CD music, in 2 channel pure direct mode as that is ok, but for movies I'd still re-direct <40hz or <60hz from the speakers to the sub. The filter is not a brick wall, so if I set it to small 60hz, sub 60hz is still being played, it's just sloped off below that.
