PreSonus Eris Sub 8BT — 8-inch Active Studio Subwoofer with Bluetooth for Multimedia, Gaming, Studio-Quality Music Production - Black

If you produce any thing with any sort of base, it doesn't matter how good your monitors are, you need a sub. I have giod monitors and great headphones, but my mixes came out muddy as hell anywhere I played the music that wasn't a decent set up. Adding a sub to my set up has let me mix in those lows soooo much better and it's made playing it on sub standard speakers sound so much better too. So it made the mixes sound better on a good setup but also made it sound better on a crap set up and got rid of a lot of muddyness. Having a sub truly is imperative to producing/mastering your own mixes. Looks great, functions as you would expect, plenty of drive, connects through Bluetooth (though I have it set up connected to my monitors through cable) size is as stated so nothing to worry about if you have a specific area you want to place it. Not remote controlled but honestly who needs that when you have the controls on the PC right Infront of you. The Bluetooth is pretty useless I feel unless your whole system is set up on bluetooth, as you need to either have Bluetooth or your audio interface playing, you can't have them both on at once unless you can find a work around.

Perfect for its size, and packed with features, good bass quality and also Bluetooth connectivity…

The connectivity, both cable wise and bluetooth, is very good at this price point. XLR would be nice but the TRS is good enough. The sound is something else for an 8 inch sub. If you want to annoy the neighbours, just an example but not a good idea so please don't do this, this sub can go very loud. Tried some DnB and this thing was shaking the floor. Surprised me how this handles dance music. It also sounds very good at low volume and quite detailed for this price point. All in all, a great sub for the price and size.

Nice little sub, solid connectivity options on the back and performs well for the price. Paired it with my AudioEngine A2+ and it fills in the void at the low end nicely, gives it a good bit of kick where it was missing before. Quite compact, so fits nicely under my desk. One thing to note for anyone buying, mine arrived with the voltage slider set to 115V! (Despite being a UK SKU and coming with a UK cable). Thankfully it is properly fused and comes with a spare you can throw in to get going again, but don't be an idiot like me and just plug it in and go, it will pop and cause needless panic...

Well built, looked and worked well, but I enjoy producing music, and the subwoofer didn't really make as much difference as i had hoped , so I returned it. Depends on what you are using it for I suppose.

I bought this for my home Spin cycle studio on a whim and it's really pulled the room together! The build quality is superb, and oh my God that bass - it absolutely kicks. I've had to turn most of the knobs down to one to avoid blowing out my windows. Absolutely outrageous how much bass this thing can generate and keep it so tightly controller. I doubt you'll get more joy for £155 anywhere else.

I needed this for my home studio. It's loud enough, and I have it connected to some krk rokit 5s. It makes the world of difference Not exactly the use case it was designed for, but it's working just fine! It sounds good, the standby works as expected, and it was way cheaper than the alternatives. I'm a happy budgie

Easy to set up. I have mine running from my PC to the sub, then sub to my two Eris 4.5 monitors and boy does this bass fill the gap the monitors left!! It's very loud and punchy for its size. I have the gain dial at around 8 o'clock and it is more than enough. Good for small bedroom studio setups. More than enough for me as I use it for producing and DJing. 4/5 on sound quality because there was interference coming out of my monitors! This was an easy £5 fix with a Ground Loop Noise Isolator.

I do music production using the Adam A3x which lacked in the bass department. This helped it negate the disadvantage and helped to give a more uniform bass sound. It’s cheap for the performance you get out of it. I have a small Room so this 8inch is enough else it be bass will echo or linger longer. Pretty good and useful. Makes listening to music more fun.

You can adjust the highest frequency it picks up but above somewhere around 70 Hz it's starts to sound boomy/boxy with an unpleasant resonance. I wanted it to cut in at 100hz to overlap with my Edifier bookshelf speakers but it's very unpleasant like that and I had to cut it down to 60hz to get rid of the boom, which barely overlaps, if at all, with my other speakers. There's cross-wiring somewhere in my system because I had to use the switch to reverse the polarity to be in phase with my other speakers, so that is a nice feature for me.

Perfect match with my Eris E.45 HD 2-Way 4.5" Nearfield Monitor and PresonUS Audiobox Go. Rocks my room, awesome sound!
