How to test sub quality?

[Imrahn]

I have a few low freq audio samples, but the player sends audio only to the speakers since its stereo,na? Then, how can i use these audio samples to check the low freq performance of the sub?

Am using PC as my source via analog out.....

Thanx in advance for any sorta help.

Regards

PC is definitely not a good way to test subs as the sound card may not be able to handle all frequencies well. You need a source (such as an AVR), that can send multiple frequencies down.

whats your cross over set to?

You could take speaker level inputs and connect them to the amp, if it is able to handle both line level and speaker levels inputs.

@Marsilians: I have connected PC via Yamaha 663 mate....

PC--> Analog Out-->AVR--> Speakers

@GeorgeO: The sub(Wharf SW150) has both speaker level as well as line level inputsHow am i supposed to connect to the Speaker Level inputs?I tried connecting the speaker/surround pre outs of the AVR to the Line Level input of the sub and the bass was thundering,but i think its inaccurate to do so na?

Speaker level inputs are the connections from amp to the speakers(amplified signals), whereas line level are from preamp to power amp or source to processor.You need to take another set of cables from your speaker terminals and connect them to the speaker level input terminals on your sub amp.
