DO NOT BUY THIS ITEM, IT DAMAGES YOUR SYSTEM BEAWARE!!! THIS SELLER IS SELLING FAULTY PRODUCT!!! DON NOT BUY THIS IT WILL HARM YOUR OTHER CONNECTED SYSTEM VERY BADLY! SELLER NAME :- COCOBLU RETAILS I got this product on 27 sept 25, I made the connections according to to the user manual, and within seconds it damaged my Apple Silicon M4 Mac Mini machine which is worth 3 times the cost of this subwoofer, I already have Presonus Eris 3.5 Studio Monitor Pair bought earlier, when connected altogether to my Mac Mini and power switched ON, it had my mac mini damaged instantly with little spark inside, Later I checked it again with Bluetooth Connectivity using my phone, The monitors produced very low sound ( they’re working fine otherwise), and this Product ERIS SUB 8 BT isn’t producing any kind of sound. CANNOT TELL ANYTHING ABOUT SOUND QUALITY AS IT NEVER PRODUCED ANY SOUND!

I paired Sub8 with Adam D3V. Even D3V has relatively good bass down to around 50Hz, but it's only a 3.5" woofer - you can't beat the physics. I cut off the low frequency on D3V using the HPF on Sub8 around 80Hz, resulting a very clean and tight bass even in low volume, which with D3V it's just impossible. I use this combo as a nearfield setup and I think the result is most perfect.

This subwoofer seriously impressed me. It's a beast for its size. The power is the first thing you notice, it hits hard and clean without getting muddy. For an 8-inch sub, it delivers deep, punchy bass and can easily fill a room. It’s rated around 100W and can reach down to roughly 30 Hz, and you can absolutely feel that low-end presence. The controls are where this thing really stands out. You get adjustable input gain, a variable low-pass filter, and flexible tuning options so you can dial it in perfectly with your speakers. It’s not just plug-and-play (although it certainly can be), you can actually fine-tune your sound, which makes a big difference for both music production and casual listening. In terms of versatility, it works great across the board: studio monitoring, gaming, movies, or just listening to music. The Bluetooth feature is a nice bonus too, making it easy to connect without extra cables when you want a simpler setup. As for value, it sits in a really strong spot. It’s not the cheapest sub out there, but for the performance, features, and overall sound quality, it absolutely justifies the price. You’re getting something that feels much closer to higher-end gear than budget equipment. Overall, this sub adds a whole new dimension to your setup. If you want tight, controlled bass with real customization options, this is an easy recommendation.

muy bueno! en 12m2 anda de lujo, mis bocinas son las KEF LSX II y las conecte por RCA al sub, suena de locura!

work perfectly, recommended after struggling with other brand sellers

No sabes que lo necesitas hasta que lo tienes, no lo pienses, si tienes los Eris 3.5 o hasta los 5" este sub es maravilloso, ni opaca ni le falta, suena con un detalle y precision increíble, nada de frecuencias molestas, no se compara con ningún Estéreo, sistema de audio o componente, es super potente y hermoso, calidad en materiales, vista, sonido.
