Being "limited" to smaller speakers is not an issue for me as desk space is a major consideration. Having said that though, I'd be looking for some level of quality from this sort of setup. The Audioengine A5 is well reviewed as a set of active speakers (I've not heard it). Hopefully the A1 can at least match it, when fed with a good source and paired with good speakers.
 
Any suggestions on where to start looking for small but great sounding passive speakers, that would be adequately driven by the A1?

14watts per channel isn't much, why only 14watts per channel, why not create a powerful amp like the e9 is a very powerful headphone amp, what about 200watts per channel id buy that.

A1 is an desktop mini AMP, it is design to drive some small speaker ! the best will be some 3 or 4 inch speakers! and also the dimension  of A1 is the same as E9! so it is really not big and save your desk space!

There aren't many 15watt passive speakers about , there normally 40watts plus , maybe you could make some small passive speakers to go with it.

For example? note that 15watt is RMS power, and it is suitable to dirve most 4 inch speakers! like AE100/AE1 from Acoustic Energy!
 
BTW, I think you may refer to handle power of speakers !

Unlike our other products, we will only manufacture 100pcs A1 first , to test the market! so the quantity is very limited and the price is a special discout for who support us and like to have a try!
 
So far I am not sure it is will popolar because head-fi is fouce in headphone and any products relates with headphone! if A1 is popular, we will make a decent speaker for A1! but the feight may become a big problem, because
 
most of our products is below USD100!

In fact, we test our A1 with JBL control one!
 

The price is very reasonable , only us$149.00, the SQ is quite good, and don't compare with some 2.1 system , it is different type of speakers!
 
A1+ control one good at music and game!
 
http://www.harmanaudio.com/search_browse/product_detail.asp?urlMaterialNumber=CONTROL%20ONE&status=

The JLB control one has "[size=x-small]Recommended Power Amplifier Range: 10 Watts – 80 Watts" , if i had a pair i'd look at 50-80watt amps to power them to get the most out of them[/size]
 

It is enought, there are lots example of 2-3 W tube amp drive a 15 inch huge speakers!
 
 
In most time, 80W is peak power for speakers! if you use sine wave signal drive it in over 30W, you will burn it!
 
 
In the past, I was an R/D manger, one time we have an power speaker, sub bass is 10 inch, bass/mid is 6.25inch, treble 1inch, and pair with a 130w amp! and the speakers was broken by the amp in the max volume!
 
And we had tested the peak output of the amp, it shows the max power output can reach 800W max!
 
BTW, if you live in a apartment! and use A1 with control 1, set to max volume, your neighbour may come and broke your door!

I can't read or see any of the descriptions or specs from the image you have attached. I'd be interested as well if I get some more information. Might be good competition for some of the T-amps. I'd think it should do decently with any high sensitivity speakers.

James,
 
I know next to nothing about speakers compared to what I know about headphones; would the best way to connect the A1 to be to plug it into the E9's line out and still use the E7 as a DAC? Right now I just have a regular 2.1 setup plugged directly into my soundcard.
 
Also, when will this deal be available for purchase? And for clarification; yes I do indeed want one lol.

Surely though a 40watt amp would drive the control 1 to higher volumes than a 14watt amp.
 

So are those specs set for now? When will this limited batch be available?

Hi,  A 40 watt amp will be about 4.6dB louder than a 14 watt amp.  To give some perspective just how loud 14 watts can get, a typical speaker has 87dB/w@1M. If the listener has two such speakers placed about 1 meter away (typical for a desktop arrangement), then the two speakers has a combined total output of about 93dB. 14 Watts of power per channel adds another 11.5dB on top of that, for about 104.5dB, and this is before adding in the effects of room acoustics, which generally will make speakers sound louder due to wall reflections and boundary reinforcements. As a point of reference, THX certified home theater speakers are tasked to achieve 85dB with 20dB headroom. Of course, one sits farther away from home theater speakers than 1 meter, so the power requirements for home theater applications are much greater. But for near field desktop listening, 14 watts is quite a bit of power to play with.

So the only difference in tens more watts is a few db.

That's correct. If the only difference is watts output, then yes, the only effect is additional dB in loudness. Typically, every doubling of power gets you another 3dB of loudness.
 
At normal listening level of about 75-80dB, an amplifier is generally at less than 1 watt of output.  It's the dynamic stuff that tap into the available headroom.

My bookshelfs are 75 RMS watts each and sub 150watts RMS, i'd never use them at full power in my small room and it would probley damage my hearing aswell, 80dB  is probley what i listen to them at on a daily basis, maybe 85-90db db if i want loud.
