    • Much better mixes
Size: Subwoofer Color: Black
Review Image by Michael Michael
I got this for my home studio and after using it to finish three songs since getting it, I can say I was definitely handicapped trying to produce and mix without a sub. I have the sub paired with my Presonus Eris 5 speakers. The songs I've produced using the sub vs. without the sub have translated much better across various speaker systems and my low end is much tighter and easier to manage. Also, when it comes to sound design, I can make much deeper and higher quality sub bass synth patches because I can actually hear and feel what I'm doing. I'd recommend using a calibrated room microphone and an acoustic room response calibration software to calibrate the sub and your speakers to your specific room as well. I found for my room I could just leave the sub in it's default configuration out of the box, but the settings on the back of the sub allow for some really nice fine tuning to get a nice flat response after accounting for the room response. Lastly, I really like the Bluetooth capability for casual listening and it works well if you only pair it with one device, but I found that if you want to switch between devices you have to press and hold the Bluetooth button on the back of the sub for it to connect to a different device each time despite already being paired. It connects automatically without that step if you just connect and use one BT device consistently with it. Kind of a weird and somewhat annoying quirk, but I don't really use the Bluetooth for anything but connecting my phone to the speaker system for leisure listening, and I only occasionally connect my laptop. For music production though, I use balanced TRS cables routed to my audio interface because the Bluetooth can add a significant amount of latency to the signal chain. In summary, if you already have Eris speakers and want to gain the valuable information your ears need to have great low end in your mixes I'd say this sub is a no brainer and worth every penny. ... show more

    • Impressive for such low wattage
Size: Subwoofer Color: White
I've got the Eris BT5's to go with this subwoofer. My buddy heard these in someone's home down where he lives and said that they sound amazing for a "budget" Monitor set. He wasn't wrong. I can't even open the set up because at about 50% volume in a 12x12 room, it's boomy and loud. You do have to EQ these though. The highs and lows won't be as rich without an EQ. Because both the Subwoofer and Sat's are BT, you do have to hook both up to a PC to get sound out of each and together. Now you know if you didn't and was like what. You'll also want to go ahead and get some RCA cables or the TRS cables, because they don't come with either for Sub to Sat connections. The Sat's come with RCA to 3.5mm and a 3.5 to 3.5 cable for phone/tablet/headset pass thru/whatever. I went with White because I'm building out a contrast setup with White n Black aesthetics. They look nice too. Good value for the cost. The next set up from these in another brand run about 250 a satellite and 300 to 500 for the matching subwoofer. The Eris 5BTs do pair up nice with the 8BT. ... show more

    • Amazing Subwoofer
Size: Subwoofer Color: Black
This subwoofer is remarkable for deep base from an 8” driver, but that is only the beginning. It produces highly accurate sound across the bass spectrum. Instruments sound realistic and tonally correct, with spatial accuracy that far exceeds any bass unit I have owned in the past regardless of cost. And, the sound adjustments make it easy to blend with other speakers. Seriously- a great sub and a great value. That may read like ad copy, but to me it is a joy to endorse a product that has me listening to my CD collection again and hearing a whole new level of detail. ... show more

    • Works as advertised. Bluetooth is really useful!
Size: Subwoofer Color: Black
I have been using small coaxial studio monitors in my little project studio for years. They sound wonderful, have a lot of bass but can only get so loud. They are also a little long in the tooth, so I wanted a subwoofer to take the low frequencies off their workload and pulled the trigger on this PreSonus as the price and feature set was right. Several months into owning and using it, I can say it works beautifully! You have to take a little time balancing the volume and the crossover frequency as you would when pairing any other subwoofer with a set of speakers that it wasn't designed specifically for, but when you get it right, you get a very smooth transition and it just gave my old beloved monitors a new lease on life. I wanted to write this in response to the reviews trashing this subwoofer saying it is under-powered. My *guess* is that those reviews might have been written by people who do EDM or hiphop productions or the like and they are overpowering a small subwoofer with over-emphasized bass frequencies. I mean, if that's what you're into go get a bigger subwoofer. I like smooth, accurate EQs, and this provides well on a budget. My $0.02. ... show more
