Review: DAW and general use - I got these at the start of the year and waited a while to see how they worked out. For recording, they are excellent and I had no problems connecting to my PC. The 4.5" speakers have enough power for home use and can keep up with a guitar amp at home volumes. The cables for connecting the speakers were a bit short for my needs so I bought some 16 gauge wire and that was adequate. The slave speaker is 4 Ohms, 25 watt so up to 25 feet, 16 is fine. If you want longer, go with 14 gauge. The Bluetooth connection is simple and convenient. It turns these monitors into something very convenient and I wish more manufacturers would incorporate it. Being able to connect your phone or tablet is just fun. Something I think matters in a product in this category. No cables to listen to music on your phone, no messing about or booting up the computer. There are plenty of connections on the speaker and they will likely suit most home users. These are not high end studio monitors. For home use, this is actually quite a positive and part of the reason I wanted them. Professional studio monitors are extremely directional. These are, as all speakers, somewhat directional but they can fill a small room and be treated as a nice set of home stereo speakers. That may not suit pros but, if you are a pro, you will already know that and be looking for something specific. For music enthusiasts, creators and general home use, I think you'd be hard pressed to find a more compelling product. I do fancy the subwoofer but honestly, they sound good enough for what I use them for and I don't really need to shake the whole house. So, I'd definitely recommend them for home use and general listening. They would be good for a gamer that wants something better than your typical PC speakers, these really are a massive upgrade at a reasonable price. 4.5" is generally a good place for home use and that quality vs cost sweet spot. If you need something for the pro studio, these aren't that but you'd already know that if you did. More than enough for the vast majority though. They look good, sound good, work well, have Bluetooth, lots of common connections and all you need is some speaker wire if you want to separate them across a small room for a small stereo speaker system. They tick a lot of boxes and deserve to be praised.
Review: Awesome sub, truly is a game changer if you produce your own music. - 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.

### ⭐⭐⭐⭐⭐ Awesome sub, truly is a game changer if you produce your own music.
*by W***N on 12 August 2025*

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.

### ⭐⭐⭐⭐⭐ Excellent features and fantastic performance.
*by D***D on 30 March 2026*

Excellent features and fantastic performance. This sub make a great accompaniment to my PC speakers which while good, needed a little help on the low end from a sub. What's great about this sub, is the stereo in and stereo out function. Keeps my PC setup sounding great and cuts down on too much equipment. I'm currently using Bluetooth function, as it still sounds great and still allows use of the stereo out RCA ports to pass the signal on to my active speakers. Tip for PC users with active speakers: Use a separate USB volume control knob at the PC end as master volume control (search amazon). Set your active speakers to half volume and set the gain (sub volume) to produce the correct amount of bass at that half volume. Set high pass filter to ON, then set crossover at 80Hz. (This is a good starting point)
