I have the smallest version of the Emotiva, at bass set to -2 and treble 0 they sound quite balanced to me. not at all bass bloated. I find them to be really good for their size and price. also look really cool.
sucks that they demo'ed them that way, they aren't bad at all.

Possible. IMO Emotiva could have done a better job at setting up their demo room.

My current computer/desktop speaker rig consists of the super over hyped Pioneer Andrew Jones bookshelf speakers bs22lr ($77/pr) sw8mk2 sub ($90) and a Parasound Zamp v3.  Needless to say I've had a bunch of speakers and amps in this position over the past few years and the current setup I am very happy with.

Maybe it's just the right setup at the right time but the speakers and sub for that matter sound great even at low volume levels, something I had a hard time finding with my other configurations.  At first I thought the cheap price, small sub, and small 4" woofers of the speakers would sound terrible but I was pleased at first listen.  IMO they do deserve the praise they get.  The sub btw is more like adding another speaker that can play just a bit lower than the bookshelves than a real sub. The specs say it only goes down to 38hz which is pretty sad; I think I'd hate to try to use this setup in a home theater type rig but for desktop music listening it works.

I got lucky and snagged the above pieces on sale or used at great prices and would even say they are worth it at full retail.

 :)p13 I just bought a sw8mk2 for my mini while-the-kids-grow-up home theater some few days ago! It should arrive anytime now.

The story is that my Mirage mini-sub plate amp died. The plate amp is a weird form factor and the candidate replacements were more expensive than the sub itself. Of course I opened the sub and besides finding some caps blown in the amp (woofer is in good condition) I found some Legos and toys stuffed inside...

Both subs are 8", and cover more or less the same frequencies. Bigger, more powerful and expensive subs will definitively dig down deeper and harder :-*... Good things come to those who wait... or so I keep telling my sorry self...

The Z-amp is just perfect for running passives on a desktop. Got mine used for $100. So much power in such a small package. The relay on the v2 kind of annoys me though.

do you remember which model they were? I haven't heard the bigger ones.
and uh, dumb question but how much difference do stands make for bass? I'm debating whether I should get some yoga blocks or something to put under them.

I honestly don't remember. I took a picture but it came out dark (demo room was dark). From memory I think they were on stands.

Placement obviously makes a difference, but dunno about the yoga blocks. I know Audioengine sells desktop stands that change the horizontal angle and might help absorb resonances. Angling the drivers (horizontally and vertically) towards you may improve balance, but I don't know how the Emotivas will respond to this.

The mm220s seem to roll about 3.5 dB/decade when toed out 45 degrees and about 5 dB/decade when toed out 60 degrees. This roll off is not always graceful though (some peaks and valleys may develop at different angles depending on the speaker design). You could also experiment with distance to walls (Emotivas I believe are back ported).

BTW, my Pioneer sw8mk2 arrived today. The internal tube of the port was detached (... well it was $97 after all). So while opening it to fix this smallish issue this is what I found:

- The Pioneer MDF cabinet was about half the thickness of the Mirage sub.
- Cabinet was not reinforcement (neither was the Mirage).
- The damping was better done than the Mirage (polyfill on top and sides, Mirage only does the sides).
- Pioneer woofer has a lager magnet and steel frame. The Mirage a much smaller magnet and plastic frame.
- The port on both sub is about the same diameter and length (tuned similarly perhaps).
- Pioneer box is wider and shorter.
- Pioneer has a cross over knob... Mirage does not.

To soon to tell, but so far so good with the Pioneer.

There's also these. I don't know how much absorbing the Audioengine wedges are going to do, they're just plastic aren't they?

Well (Edit: I should have been more clear and said cabinet resonances) , some small and sometimes cheap computer speakers tend vibrate significantly at certain volumes. Plastic/Foam feet/blocks might help in absorbing the dancing around of a lively speaker which otherwise would make noise against a table or shelf... I guess one could weight them down to.

I don't think the plastic wedges would alter much FR/IR resonances unless they change speaker orientation...

K, I was a little wrong about the little budget  Pioneer sw8mk2 sub. The thickness of the cabinet of the Pioneer is 10/16", while the Mirage is 12/16" (i.e. not that much different). I think it's sort of optical illusion. The Pioneer is a great little sub for the price (definitively better than what came with the old Nano-sat combo).

Pics:

Pioneer cabinet thickness, top/left/right damping, and port


Mirage cabinet thickness, left afterthough damping, speaker magnet/basket(plastic) and port


Pioneer speaker magnet/basket(steel)


Mirage speaker cone and surround


Pioneer speaker cone and surround


The two subs (not much different in terms of dimensions... seems more like an optical illusion as well)


Sound:

The Mirage is IMO more punchy than the Pioneer, but the Pioneer is much more accurate and fills the low end void better than the Mirage. Certain percussion sounds that were absent in the Mirage are making their way out of the Pioneer. Given the nano-sats roll off way too soon, the fact that the Pioneer has a way to dial the cross-over all the way to 150 Hz is a good reason to kick the Mirage sub in ass and out the door.

Neither one of these subs is the ultimate expression of hi-fi, but the Pioneer does a great job in complementing small HT satellites in situations were placement/space is severely constrained (I may be able to condition another room for some better gear... later), and where a more serious sub may be threatened by little plastic soldiers looking for cover.

Possibly much better small subs are out there commercially and for the DIYer.

How is the placement working out at your desktop? I can't really tell from the pics. Are they sitting right under your desk as foot massagers, or are they a bit off to the side?
