need help with audio connectivity

[Ewan_2]

Hey guys, before i buy this subwoofer:
http/www.ebay.com.au/itm/Klipsch-Reference-R-12SW-12-Powered-Subwoofer-200-W-RMS-400-W-Peak-/281995792421?hash=item41a8425025:g:jXwAAOSwbwlXBmTo#rwid
I would like to know if i can play music on both this subwoofer and smsl q5 pro powered bookshelf speakers at the same time if i connect the sub to my mobo's soundcard.
-amp is connected to pc by usb -amp is 102w and speakers are klipsch r-15m (80x2 W)

Your smsl q5 mini amp has a dedicated subwoofer out port mate.

Makes far more sense to just use that instead.

You may find issues trying to run both a USB DAC/amp & the boards sub output at the same time.

Will work fine from the amp itself though

but will the amp/dac be able to handle 200-400w i mean my bookies are already clipping. also would be great if you reccomend a 2.1 reciever for my setup
Thank you!

Its a powered sub mate , does not take power from the amp - it has its own amp built in.

You can use the amp you have but look for a sub with speaker pass through.

This way the bass is powered by the sub amp alone & the amp power output (its no way a 45w per channel amp in real terms) willbbe used just for mid/high end to the speakers.

Should remove the clipping from the klipsch speakers as bass drains the amp power much more than the high end.

i love you. very helpful

The polk 110 would be ideal for your setup mate , speaker level inputs & outputs.

are there any advantages of that sub over this one http/www.ebay.com.au/itm/Klipsch-R-110SW-Repack-Full-AUS-warranty-/122413243913?hash=item1c8065de09:g:aI8AAOSwmgJY1JND#shpCntId
because i look the look of this one and its a good price
i mean is clipping really that bad
i know that the polk sub can power the monitors through cable but the klipsch sub does the same right without cables

 

[Ewan_2]

cant play 85w speakers on 25w amp hahhahahha

 

[Ewan_2]

you wont believe it all i did was turn up the volume on the amp and no more clipping. i even turned pre-amp +3db
is this for real or Equalizer APO is bullshitting me

 

[madmatt30]

distortion is a sure fire sign that the speakers cant handle the amp volume
Clipping is the opposite & a sure fire sign that the amp cant handle the speakers.

The polk I suggested becasue it has high level (speaker) inputs, high level (speaker) outputs AND a built in crossover & filter for this cable option.

What this means is you wire the speaker outputs on the smsl q5 pro to the sub speaker inputs.
You wire the klipsh book shelfspeakers to the sub speaker outputs.

When you then set the crossover dial on the subwoofer itself , The sub then only plays frequencies below that crossover setting & passes ONLY the frequencies above the crossover to the bookshelf speakers.

Its powering the low frequencies to the klipsch speakers that is sucking up the wattage from your amp & causing the clipping youre hearing.
Once you remove the low frequencies & let the sub amp deal with them youll have 50-60% more power available for the mid & high range frequencies on your klipsch speakers.

This is the way a 2.1 setup should be run .

Running something like the klipsch sub straight from the subwoofer output on your little amp will push a full range audio signal to both the sub & the klipsch speakers beacuse it has no low frequency filtering built in,not a problem for the sub as it has an adjustable crossover - youll still get clipping on the bookshelf speaker though once you up the volume the same as you are now.
You may not notice it as much simply because with a dirty great 200w sub sat there youre probably not going to run the volume anywhere near as high but its still not the ideal solution.

previous reply was done while you were posting your last one.

You mention a pre-amp now ???

 

[Ewan_2]

your right

what happened was I decreased the volume of windows to 76% and spotify & increased the volume on the amp. then i checked equalizer APO which was what i was using to monitor clipping and its gone. using the equalizer i up the amplification by 3db and still no clipping in the APO. I'm confused as []this is only my first setup.

edit: i was playing "bass i love you" in spotify and the apo says there's no clipping but i can hear a buzzing sound out of the right speaker, could be part of the song but i dont have any other amps to confirm
