QED Reference Subwoofer 40 benefits from over 40 years of award winning expertise. All QED cables are designed using the top down principle with the Reference range representing the pinnacle of musical performance. QED Subwoofer 40 was designed primarily for low capacitance as this has been identified by QED as one factor which leads to a hi-fidelity experience and makes for a tight sound which retains the rhythm of the original piece.
This is vital when it comes to the 'bottom end' minute timing errors are eliminated by the use of QED's complementary conductor technology and a special floating Zn/Mn ferrite jacket. These technologies absorb very high frequency noise signals outside the audible band. The QED Analoc plug design eliminates eddy currents which affect the micro-timing of the audio signal, maintaining the fidelity of the audio signal from start to finish. Reference Subwoofer 40 is further optimised by having a 25% smaller diameter than Reference Audio 40 making it more convenient for those long runs around the room.
Complimentary conductor technology improves timing and detail, retaining the rhythm of the original piece. Unlike conventional analogue interconnects, Reference Audio 40 uses two silver plated 99.999% oxygen free copper conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative signal path for more subtle audio components which might otherwise become time smeared in a single audio pathway.
Internal Ferrite Jacket
The floating internal ferrite jacket absorbs high frequency noise signal components outside the audio band. When measured using high frequency measurement equipment, Audio 40 products convey a comparably cleaner and tighter signal pattern when its special Zn/Mn ferrite jacket is present. This has a beneficial effect on audio signal micro-timing and may account for the clear preference expressed for the ferrite jacket in listening tests.
Analoc RCA Plugs
This all new locking design features small high purity gold plated copper conductors in place of the usual large volume brass body found in ordinary high quality plugs. This cuts down or eliminates the tendency for the changing magnetic field in the conductor to induce eddy currents which are thought to affect the micro-timing of the audio signal. Coupled with its hollow central pin, the new QED Analoc plug maintains the fidelity of the audio signal from start to finish.

Order and Delivery Information
Thank you for considering Yorkshire AV for your next investment in your AV setup.
We are an approved retailer for all brands sold on our website, which means full manufacturers warranty and support as well as detailed product knowledge within our small business.
We use an inventory tracking system which states if item(s) are in stock and if not, what are the likely lead times.
Selecting "Next Day" delivery does not mean you'll receive your item the next day in some cases. It's the next day from when the item(s) are in stock with us. If there is an urgent need then please contact a member of staff via the Live Chat or telephone (01757 826111) to check on live stock levels.
We do ask for some patience during lockdown - we're working remotely from home and travel to the warehouse each day to fulfil orders. If item's aren't in stock - we can usually get them within a couple of days.
We're a small business that's been impacted massively due to COVID-19 and have such had a significant reduction in orders. We're focussing on core products and services with less frequent products being ordered "on demand".
When will orders be dispatched?
- Orders placed Monday - Thursday before 2pm and are in stock will be dispatched the same day for next day delivery. This relates to product that state 'In Stock for immediate dispatch' on the product page.
- Orders placed on after 2pm on Thursday or on Friday will be dispatched for delivery on Monday unless Saturday delivery is selected.
- Orders placed over a weekend and are in stock will be dispatched on Monday.
Orders for items not in stock
Given the vast amount of variations of each product (e.g. AudioQuest cables) or Pro-Ject Audio Turntables - we keep the most common options in stock (i.e. gloss black finish, or 1.5m RCA cables) whereas longer cables or cables with terminations that are less frequently ordered will be ordered as required.
Generally speaking - we receive orders within 2-3 days for UK suppliers and 3-4 days for European suppliers (i.e. AudioQuest, DALI).
We want you to be 100% satisfied which is why we'll give you an email/call if item(s) aren't in stock and give you the option of changing the order, cancelling or if you're happy to wait a few days, we'll get it out as soon as possible.
If an item states 'Available to order. Usually dispatched within 48 hours' - this means the item is not in stock but we are able to order in. Lead times average 2 days but in some circumstances, delivery times may be longer and is outside of our control. Please contact us to get an estimate on delivery times if orders are urgent.
Who do you use for delivery?
Our primary delivery agent is DHL. Where orders are shipped directly from Yorkshire AV, we always use DHL who offer a fabulous service at competitive rates.
If we drop ship (i.e. direct from the supplier) then the delivery agent is out of our control. It is generally DPD or UPS however - we rarely see other carriers used.
As always - we welcome a conversation about your requirements and will always explore all options to connect you with the right solution.
