Swissonic Sub10

Has introduced humming and buzzing and random pops into my monitoring system, even with fully shielded and balanced connections. Not good.

The crossover is apalling. It's not a crossover, it's just a low-pass filter. If you pass your monitors through it you'll lose everything under about 180Hz in them, regardless of where the crossover is set and you have no option to change it. So then the only option you're left with to recover those lost frequencies is to have them through the sub. My speakers sound fine down to around 80Hz and are very very good, so now I have to sacrifice most of the bottom end in order to get the lows I was initially after. And the 80 - 180 Hz range on it is just too much.

You either have to..

a) Run your own crossover system
b) have a dedicaeted sub output
c) Run the sub at 180-200 hz and compromise your monitors and deal with the stupidly agressive volume

The volume knob is completely useless, it's like the stereotypical hot and cold shower controls, 1mm to the left and you get nothing, 1mm to the right and it's drowned everything else out, then doesn't appear to do much for the rest of the 300 degrees.

If your monitors have a low frequency cut off oif their own then you MIGHT be able to get away running them straight through, daisy chainging through the inputs and effectively running the system in paralel rather than series, but this is far too agressive to be useful to most setups.

Don't waste your money, go for something with less grunt and more control. The features and performance of this product lead me to think it's more suitable to home theaters than in a studio, and should not be advertised as such.

I have been using this sub with a pair of JBL LSR305p and overall I was very pleased with it for the price.

Here are my thoughts:
PROs:
- Extends down enough to make music a lot more enjoyable.
- Has plenty of power to work with
- Fair accuracy for the price
- For the price, you can't get a better sub in terms of power/ frequency extension

CONs:
- Very big and extremely heavy, it really is a huge monster make no mistake
- Crossover knob is cool but it doesn't cut the freq just right, you will hear the crossover struggling for sure
- Unbalanced inputs would have been something really useful, one of the TRS inputs on the back was loose, but still worked with a bit of fiddling
- Big sound pop when the sub comes ON
- Gets pretty hot after few hours of listening

Overall I'm fairly pleased with this sub. I wish they would make a 2nd version of this, fixing the minor problems and keeping it on the budget side.

I bought this sub recently but I am sorry to say that I am about to return it.
Sub produces what sounds like a continuous 60hz mains hum which is prevalent and audible. This happens from when the unit is turned on, with nothing plugged into, and/or connected to speakers. This renders the unit unusable for most studio applications as you will hear the hum clearly when there is silence. Also I found the sound, even at low levels, to be a little fuzzy/distorted. The unit is otherwise sturdy and well built, There is a LOT of power in this sub, and if you are buying it for home stereo use it might be ok for your needs but I could not recommend this particular unit for mixing/mastering as the hum will drive you nuts and there is no cross-over as such, but rather a low-pass filter. I have instead opted for the Prodipe Pro 10s at 100euro more, so I will see how that one fares out.

After week of using this sub, I'm pretty satisfied!
This thing has huge amount of power, although you will probably not use quarter of it (in order to match the levels to my Yamaha HS50m, I'm having this thing at about 15%, with crossover at about 60hz).

Bass response is very quick and price, no rumbling (when level-matched), this sub generates very deep but precise sound.

I was pretty stoked about the finish of this thing - I was expecting some cheap abs, while this thing is build exactly as good as Yamaha's HS series.

The 'power saving' function is indeed poorly designed - there are some audible clicks in your main monitors when 'waking up' the sub, however I find this really not very annoying.

If you want to actually know what is happening with your mix in the low freq, this is the best solution for the money.

I think thomann and their swissonic brand did great job with this product. Totally recommend it.
