This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:

Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.

Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.

Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).

45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.

If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*

* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty.

Powerful bass, produced in the digital domain; the Q Acoustics 2070i subwoofer breaks new ground at this price level.

Digital Signal Processing

Marking this subwoofer out from its rivals is it's completely Digital Signal Processing (DSP) driven system with efficient Class D amplification. So, like much more expensive subwoofers, the 2070i carries out all its filtering and limiting functions in the digital domain. This not only gives superior sonic performance through greater precision but also enhanced flexibility and adjustment.

Twin cones for added punch
Rather than using one large cone, the 2070i uses two, smaller cones. This has the advantage of offering the same surface area as a larger cone, so giving you depth and rumble, but also improved speed of bass. Smaller twin cones can move faster and therefore offer a punchier sound with more accurate timing. Thanks to the built-in 150W digital amplifier, power and control are never an issue, either.

Function control an quality construction
The 2070i features speaker type function control. This lets you optimise the performance of the subwoofer as to whether you're using bass reflex (ported) or infinite baffle (sealed) speakers. And as well as sounding better than most subs at this price, the Q 2070i is also better finished, with flush-mounted drive units and curved edges for beautiful aesthetics and distortion-free sound.

Whatever speakers you might have, such is the flexibility of the 2070i that it's one of the most talented subwoofers in class - deeply impressive!

Rated 3 out of 5 by Not happy with this for music While it's a decent sub for movies and TV - although still sounds too muddy and mumbling for my taste - it's really not good with music. Sounds very muddy and I'm having to get used to all of my music having an inaccurate and not great for precise base. 17 July 2016
Rated 4 out of 5 by worth the price I need something narrow, lack of room. Its clean tight bass due to dual cones.DSP better sound from amp. Not the most boomy bass.Better than the MRW10 just....better for movies than music which is what I use it for. I also bought the Q ACOUSTIC 3070s which uses kevlar type cones,smaller lighter unit. The 3070s sounds better...but the price on this unit is very good so its a choice to make between the two. Tom Griffiths let me test both,helped out all the way.I kept 3070s Again solid customer services whom dont stop until customer is happy.Impressed at his efforts. 29 June 2016
Rated 2 out of 5 by mediocre bass The quality of the bass coming from the subwoofer is probably below average. Overall, I'm not impressed. 23 June 2016
Rated 5 out of 5 by Great sub at great price I got this sub as part of the 2000i surround sound package. It sounds so much better than my last sub with crisp bangs and explosions in action blue rays and subtle fill in during quieter action. I am very pleased with the sub and the helpfulness of the Nottingham store. The only downside is the odd shape which is harder to place aesthetically when the wife is not as keen on black boxes around the house. 20 May 2016
Rated 5 out of 5 by So pleased that I bought two! I bought one of these to compare to MRW10. I instantly liked the 2070si much more, due to (at least to my ears) more accurate and controlled bass. I was so pleased with the one I bought that I went and bought another two days later to make a 5.2 system. Just tried it out with the beach scene of Private Ryan. Wow! Much prefer these to the MRW10, which sounds rather flabby by comparison. Some may hate the design, as they are VERY deep for a sub (indeed for ANY speaker), but I really like it. So if WAF is a concern, you may wish to look elsewhere. But if decent sound, at a very good price is your concern, then give one (or two!) a go. 13 April 2016
Rated 5 out of 5 by Completed my set I've just added this to my all round Q Acoustics 2000 series 5.1 set up with a Yamaha RXV677 amp and it packs a bit of a wallop. I only live in a small flat with wooden floors and it vibrates through the universe. I watched Spectre with it the other night and I thought my living room was going to disintegrate. I've set it up at sensible levels with a sensible crossover and it still kicks hard. Sounds excellent with music as well as film. Highly recommend. 26 February 2016
Rated 5 out of 5 by Great Subs. I have two of these now as part of my home cinema setup. Awesome bass I think you would pushed to beat for the price. They are rather large so make sure you have room for them if you have limited space. 20 February 2016
Rated 5 out of 5 by Excellent product The last of my purchases to complete my 5.1 system, which it complements perfectly. Complete smooth integration of sound. Q Acoustics speakers are a fantastic product & the total system price at this time (Jan 2016) is brilliant. 20 January 2016
