Hello there! 

 

First of all i am new to this forum so ill introduce myself, im kalekip21 from the netherlands ^^

 

Then,

 

I recently bought a jamo sub660. i got a feeling this sub can do more then what it is showing me right now.

My amp is a Sony STR-DH520 and i feel im not getting everything.

 

Any tips on how to configure it or advice?

 

Thanks!!

Your room size and layout?

Set your speakers to small with 100Hz crossover frequency in the AVR. Bypass LPF on the sub by dialling it to its max position (200Hz). Use input marked Left/LFE on the sub.

Where is the sub located in the room? Is it on the front wall next to mains or side wall or behind main listening position?

Woopsy daisy!!!!!

For a start just put that sub in any of the front wall corners, keep the gain knob in mid position on the sub, and run the auto set up routine on your AVR.

Once that is done and you get the proper distances for all your speakers and sub and they are level matched then set your speakers to small, crossover frequency at 100Hz in avr. Make sure you bypass LPF on the sub by dialling it to its max position (200Hz). Use input marked Left/LFE on the sub.

If bass is less; feel free to bump up the sub trim level in AVR. If still you feel less bass; raise the crossover for all the speakers in the AVR to 120Hz. Try and check how it sounds to you.

Also..............if those are your mains and that is the screen you'd watch movies on; push your mains further apart in order for you to have a wider sound stage. That's the first thing you must do before running auto routine on avr

Could you explain this a bit more? "For a start just put that sub in any of the front wall corner, keep the gain knob in mid position on the sub, and run the auto set up routine on your AVR."

By the way i am soon to buy some new main speakers,

 

I was looking at the Jamo S608, or do you have some advice on better speakers? 

And if i do get new ones, would i need a new AMP?

 

Thanks!

The only limitation posed by receiver that I could think of could be weak pre amp signal to subwoofer resulting in low output from the sub.

What do you mean by sub being really loud when you when you turn on and then it gets soft?

You don't need to change your receiver. Nothing wrong with the sub either. It's your room and how your system is set up. The only things, for now, that require changing are the room and positioning of the sub/speakers.

A subwoofer is not a shotgun, so, aiming it at the listening position has no effect. A sub radiates energy in all directions. Anyway, your current listening position is almost in a null (weak or no bass region). It should be where the drawer/closet is in mid rear wall position. I think the ideal position of the sub is in the front left corner; but that place is occupied by the wall/pillar. Anyway the current position of the sub will still work ONLY if you move your listening position.

Just play any bass heavy song and stand next to the sub where the closet/drawer is. You should hear strong bass in that region. Also, your room is cluttered with closets/drawers. All these objects mess up with subwoofer response in the upper midbass.

That room is so small a tweeter could shake it. Are you sure the cone is even vibrating ?

Actually what I would do is buy one of these little splitters and try it with both inputs at the same time. My JBL es150p just doesnt like it if I use only the LFE input, output from the PC, so I connect them both.

There is absolutely nothing wrong with how your sub is hooked up right now. It's only the placement issue of listening position and sub. You are almost in the middle of room both width and length wise. Move you LP further back i.e. close to rear wall and push your sub into left or right corner then rerun auto calibration.

You can add a $10K sub in the mix; you would have the same result if you don't set up your system properly. Placement is the foremost step when it comes to subs.
