Hi guys i have posted on these forums awhile ago regarding my subwoofer dying so have been using just the speakers from this package: Wharfedale DX2 (Black)
with some of these as high fronts for atmos : DALI ALTECO C1 (White)

i have been looking for a stop gap subwoofer to get me through till maybe the middle of this year and then i can get one of the recommended BK P12‘s.

just a quick look at richer sounds: Search results for: 'Subwoofer'

anyone one of them good enough, ideally prefer one that is under the £200 bracket.
i use a denon avr-x2400 to connect everything to.

No point in spending loads of cash if it's only a stop gap, This Polk is highly rated for the price and should do the job as long as you don't want earth shattering volumes.

Thanks guys for your info,
So have to decide between the:

Or


I know I’m just getting a low end subwoofer for the price, but any one more favourable to one of them looking at the specs ?

To me 50w in the Polk is far too low.

@MaryWhitehouse thankyou for your info,
Will get this bought and im sure I will ask you what settings you have regarding frequency etc,

I assume I will have to get the old denon microphone out to get all my speakers talking nicely with the new sub.

Can you stretch to 275£? This would do you good for the long term. More fun than the BK P12 also and miles better than the Wharfedale which has got bad rep here earlier.

Changed your mind then?

You can get new one with 2year amp warranty for 129£! This is grade2 so may have tiny mark, usually these are just opened/tested and in mint shape. You can call the shop, AVO is AVForums advertiser so good shop to deal with.


As you are young guy i think this would be spot on. 10" driver with downfiring port so you get some rumble going on for movies! Keep in mind if you buy used one it can start to humm or the amp can die any day. Then it´s waste of money. Get new with warranty and be safe.

No. I wouldn´t buy it personally cause the feedback is quite horrible and the amp failures, but i have listed it for persons who can´t spend more or alternative for a used 100£ sub. OP has 200£ budget and should really save up more.

If the plan is to have good looking BK then i wouldn´t buy anything as stop gap as it would be silly to spend even 129£ and then trying to sell the Wharfedale later.

The KLH is even better than BK P12 for movies in certain ways while being dirt cheap so worth to consider as it wouldn´t be stop gap.

Already ordered the sw-150 today and didn’t even no I have a £10 discount as a member, (it’s been awhile).

I know it’s nothing special but for £139 I can’t complain, as money is tight at the moment I just needed a cheap subwoofer.

So it’s here in my flat and will sync it up with all my speakers tomorrow, but looking at the back what dials should be set to ?
Volume ?
Crossover frequency ?
Phase
Auto power ?

Set volume to about 12 o'clock, turn crossover all the to the right.
Phase is fine at 0.
Auto power is up to you. I assume that "on" means that it'll use auto power and will go into standby if it doesn't get a signal. That's nice, but can be frustrating if you're watching quietly or watching a movie that doesn't have a lot of bass, and then it does suddenly have lots of bass. Off will likely leave the sub on all the time. That's not really a problem but some people get concerned about the energy draw and the effect of leaving electronics permanently powered up.

Looks like a good starting point.

Looks like a good starting point.
I originally had these settings before my original subwoofer passed away:
Front and centre 120 hz
Front heights 150 hz
Surround 110
Bass lfe
Lpf for lfe 120 hz p

Hope that makes sense lol.
But obviously this sub is a lot weaker.
I did notice you said leave the phase at 0 but I know this sub is a lot cheaper than my old dx-2 sub but I had that set to 180 ?

There's a bit of a gap then between your mains and the sub. When you turn the Frequency dial to the right, does it click when it gets to the end? If the sub only plays up to about 85Hz and your speakers are crossed at 120Hz you're missing a good chunk of the range.

Bass LFE and LPF for LFE are fine.

If you had phase on 180 before then set it to that. It's hard to know without measuring. I'd listen to it on one setting, then change it and listen on the other setting, see which is better (at your seat).

Because it’s a cheap sub it only goes to 85hz.
Will leave the phase at 0 as suggested and see if it’s enough when playing something with some bass.

Will run audyssey tomorrow and see what it gives me regarding speaker settings.

Frequency Response35Hz to 110Hz

BK has the LFE position but Wharf doesn`t have anything i tried to ask them this years ago when i helped member but no reply back. There is many subs when you connect the cable to correct input the crossover knob is not in use so it`s bypassed and then it should play higher than internal crossover in use. BK plays up to 200hz or higher like most SVS subs when bypassed.

Wouldn´t make any sense to play only up to 85hz. :confused:

Best to leave the phase to 0 as Audussey should get it right. At least in every Audussey article the engineer Chris says to leave it at 0.

Regarding this pic,
Should it be different because of these settings for the sw-150
