Going bananas trying to figure out crossover settings, HELP!

Im going kinda bananas trying to figure this all out. Not getting a whole lot of bass coming out of my new sub. My thinking is that my speakers have too high of a low frequency crossover (160hz is the lowest) and my Sub crossover is (140hz max). I know I have a relatively cheap/low cost setup, but I would like to get the most out of it, without spending a fortune (which unfortunately I do not have).
(The speakers were from a previous surround sound system).

Couple of questions:

Was thinking of getting new front speakers (possible floor standing) which have a lower frequency range. Im guessing this would help, but is there anything I can do with the setup I have now? And would I have to get center and rear speakers as well or could I keep them?

Is the sub really doing anything, if crossover set at max (140hz) and the lowest the speakers can spit out are 160hz?

If I get large floor standing speakers with say a frequency of 45hz-50,000 what settings would you suggest I change? Speakers size? Crossover?

And do the crossover on the receiver and the crossover on the sub have to be the same?

Thanks if anyone can help this poor confused guy. Haha

Below are my system stats:

5 Sony Satellite speakers (6 inch):
100W Max input
Frequency Range - 160hz - 20,000hz

Dayton Sub-1200 Subwoofer:
120W
Settings are: Crossover is 140hz (max), Gain about half, Phase (0), LFE Mono (input)

Sony STR-DH500 100w 5.1 Channel Receiver:
Setting are: Speaker Size (small), Crossover 160hz, Subwoofer (yes)

Re: Going bananas trying to figure out crossover settings, HELP!

First off, Welcome to the Shack.

Something does sound a little odd in your set-up. With the receiver crossover set at 160Hz you should be sending a ton of info to the sub. I'm guessing you need to turn up the gain on the sub.
Do you have an SPL meter to help you adjust the speakers?
Are your speakers set to Large or Small?

Re: Going bananas trying to figure out crossover settings, HELP!

Don't have a SPL meter. Speakers are set at "Small". Sub set to "yes".
On receiver speakers are all set at " 0 dB " (with the options of -10 dB to +10 db)
When I do a "Test Tone" of all the speakers I cannot hear the sub(with Gain at half). When I crank Gain all the way on the sub and do the "Test Tone" I can hear the sub, but still not very loud or anywheres near egual to the rest of the speakers.

Have you tried running the auto-calibration on your receiver?
Details are here: http://support.sony-asia.com.edgesui...4129451211.pdf

As for replacing the mains, I would recommend it, and you should notice a huge difference. If they are rated to go down to 45 Hz then typically you would set the sub and main crossover points to be around 90 Hz

Silence is golden but duct tape is silver.

Thanks. I have no idea where that microphone thingy is. I got this receiver last year. Hmmmmm....will have to look around. I know I didn't throw it away. Thanks for your help!

Was looking at these at Amazon:

Floor Standing:
Sony SSF-5000 Floor Standing 3-way Speaker
Newly developed 8" mica reinforced woofer
3.25" mid-driver
1" Nano Fine balanced dome tweeter
150-watt maximum input power
45-50,000Hz frequency response

Bookshelf Speakers:
Sony SS-B1000 5-1/4-Inch Bookshelf Speakers
Newly developed 5.25" H.O.P. cone woofer
1" nano-fine balanced dome tweeter
120-Watt maximum input power
80-50,000Hz frequency responseImpedance: 8 Ohms
1-year limited warranty

Sorry, can't post links(Im a newbie)
Could I technically get the Floor Standing ones for the FRONTS and the bookshelf ones for the REAR?
Or would you suggest one or the other just for the FRONTS(do the REARS need replacing?)

Thanks again!

Re: Going bananas trying to figure out crossover settings, HELP!

That looks like a good combination for floor standing fronts and bookshelf surrounds.
Those speakers should complement each other nicely.

Thanks for the help.

With the Floor Standing Fronts at
45-50,000Hz frequency response
and the Bookshelf Rears at
80-50,000Hz frequency response

What would I set the crossover at on the receiver and would I set speakers to "small" or "large"?

Thanks again!

Re: Going bananas trying to figure out crossover settings, HELP!

Hopefully you can locate (or borrow) the mic for the auto-calibration. This would give the best results for matching the speakers.

Otherwise, set the fronts to large and the rear to small and I would start with the crossover set around 90 Hz. (There may be an option in your receiver to send LFE to the sub as well.)

If you cannot locate the mic then a SPL meter would be handy to match the sub and main speaker volumes.

I have 2 pairs of an earlier version of the Sony SS-B1000 speakers for my 7.2 HTS. I use them for the side and back surround speakers. For the price $50-60/pair the sound quality is quite good. I have a pair of Polk M60 Series II for my front speakers. These seem to blend well with the Sony speakers. The Polk speakers are in the Sony price range and may be a better value. I am pleased with the look and sound quality of these speakers. They have decent bass response especially combined with a seperate subwoofer.

You did not mention any center speaker choice. I probably would decide on the fronts and get a matching (same manufacturer) center speaker.

Good point! It's easy to miss little details like that.
