Review: Great price for awesome quality - Great product, awesome design to me but a great price here in Belgium. I searched the web for reviews and a decent price for a quality subwoofer. 499 euros was a lot for a first sub for an entry range but decent first home cinema. And then there was desertcart.uk, : 2.38 times less price despite an amount for handling and shipping (well, its a 18 kilos sub). It works just perfect, an excellent bass: not too shaky, not to strong if you set it right. My set in a 18m² room: STR-DH790 and Eltax speakers. It adds the coherence to the whole, coherence I was looking for. I hope it will last long. Review: great subwoofer at a reasonable price - I had the choice between a pricy subwoofer here in Austria at a local store and this nice subwoofer sold by desertcart UK. All I can say - it was a great grab. In comparison with the other subwoofer, this one has a warm and hearty sound - nearly the English one from the 80s. It has a high level input and a line in for the sub out of an AV receiver as well, enough settings to adapt it to your room. Not cheap but worthy. Strongly recommended. ## Features - Amplified power 150W rms ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006GN3RM8 | | Antenna Location | For Home Theater Systems, For Stereo Systems, For surround sound systems | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Stereo | | Box Contents | Remote Control, Subwoofer | | Brand Name | Q ACOUSTICS | | Colour | graphite | | Compatible Devices | Gaming Console, Home Theater, Television | | Connectivity Protocol | Bluetooth | | Control Method | Touch | | Customer Reviews | 4.7 4.7 out of 5 stars (31) | | Enclosure Material | Wood | | Global Trade Identification Number | 05036694032602 | | Is Waterproof | False | | Item Type Name | active subwoofer | | Item Weight | 14.6 Kilograms | | Manufacturer | Q ACOUSTICS | | Maximum Speaker Output Power (in watts) | 150 Watts | | Model Name | QA2570 | | Model Number | QA2570 | | Mounting Type | Tabletop | | Network Connectivity Technology | cable | | Number of Audio Channels | 5.1 | | Power Source | Corded Electric | | Product Features | Amplifier | | Speaker Size | 170 Millimetres | | Speaker Type | Subwoofer | | Specific Uses For Product | Home Entertainment (Movies, Music) | | Subwoofer Speaker Diameter | 10 Inches | | Tweeter Diameter | 1 Inches | | Warranty Type | Limited | | Wireless Technology Type | Bluetooth | | Woofer Driver Diameter | 170 Millimetres | ## Product Details - **Audio output mode:** Stereo - **Brand:** Q ACOUSTICS - **Connectivity technology:** cable - **Material:** Wood - **Model name:** QA2570 - **Mounting type:** Tabletop - **Recommended uses for product:** For Home Theater Systems, For Stereo Systems, For surround sound systems - **Speaker maximum output power:** 150 Watts - **Speaker type:** Subwoofer - **Special feature:** Amplifier ## Images ![Q Acoustics 2070Si Active Subwoofer (Graphite) - Image 1](https://m.media-amazon.com/images/I/61xeOPEvR+L.jpg) ![Q Acoustics 2070Si Active Subwoofer (Graphite) - Image 2](https://m.media-amazon.com/images/I/6175AC3M+YL.jpg) ![Q Acoustics 2070Si Active Subwoofer (Graphite) - Image 3](https://m.media-amazon.com/images/I/71udKJUQsOL.jpg) ![Q Acoustics 2070Si Active Subwoofer (Graphite) - Image 4](https://m.media-amazon.com/images/I/61J5jShxaXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price for awesome quality *by A***E on 3 January 2019* Great product, awesome design to me but a great price here in Belgium. I searched the web for reviews and a decent price for a quality subwoofer. 499 euros was a lot for a first sub for an entry range but decent first home cinema.

All I can say - it was a great grab. In comparison with the other subwoofer, this one has a warm and hearty sound - nearly the English one from the 80s.

Strongly recommended. ### ⭐⭐⭐⭐⭐ It is quite a long unit so it may not fit in easily in some home set-ups *by M***Y on 31 August 2016* This is a definite improvement over my previous passive subwoofer. It seems to work well with my Onkyo AV receiver. It does take a little tweaking to get right but the controls allow for most people to maximise it's potential in whatever set-up it is part of. It is quite a long unit so it may not fit in easily in some home set-ups. It does produce good tight bass sounds and has enough rumble for movies. I don't really use this for music, mainly for movie soundtracks, so can't really comment on its performance, though I suspect it would do very well for music too. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/55423169-q-acoustics-2070si-active-subwoofer-graphite](https://www.desertcart.co.uk/products/55423169-q-acoustics-2070si-active-subwoofer-graphite) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
