The DALI ALTECO C-1 is truly a multipurpose speaker in both design and function. DALI wanted to ensure that the ALTECO C-1 is usable as both a height speaker as well as a traditional stereo speaker. By designing the crossover for stereo use and by keeping a strict focus on DALI sound design principles, they have created a speaker that fulfills both criteria. It is the perfect fit for adding height information to a surround setup or taking the role as an out of the way stereo speaker.
The ALTECO C-1 delivers believable height information from Atmos, DTS-X and Auro-3D movies in surround setup - not only when “firing up” using the ceiling as a reflector, but also “firing down” from a position up under the ceiling.
The ALTECO C-1 is able to achieve this even without special equalizing in order to enhance the effects from HRTF (Head Related Transfer Function) technology. A technology found in Atmos certified speakers. Instead the ALTECO C-1 relies only on the height processing done in the amplifier, when selected. If DALI had included non-linear HRTF equalizing in the ALTECO C1, it would have been impossible to use it as a versatile neutral speaker, limiting the use to only an up-firing type speaker.
Designed the way it is the DALI ALTECO C-1 offers the best from several worlds givingBookshelf Speakers you ultimate flexibility and multiple applications.
The ALTECO C-1 cone membrane is crafted from a mix of fine grained paper and wood fibre pulp. This makes the cones very ridged, very light weight and the unevenness in the structure of the membrane helps minimize unwanted surface resonances. Combining the well-behaving wood fibre cone with the low-loss rubber surround and spider suspension results in the reproduction of even the smallest micro-detail in the signal unfiltered and with high accuracy.
The angled front and the dual sound modes enable the ALTECO C-1 to be used in a multitude of speaker positions. Add height information in any surround setup by either placing the ALTECO C-1 on top of the front or the rear speakers. It can also take the place of traditional front speakers placed high on the wall or horizontal on the side wall. It even offers the perfect angle for close listening in a desktop setting.
Clarity in an audio signal is obtained by low loss of information in combination with creating a smooth and seamless reproduction in both the time and frequency domain. Another fundamental is the lowering of mechanical distortion. This to make sure that the connected amplifier will not be exposed to a larger than necessary challenge, causing loss of detail in the signal even before it has the chance to reach the loudspeaker.

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.
