How different is this from the POWER ACOUSTIK PD-931NB?

The hardware is identical, and accessories are interchangeable, the only difference is the look of the icons in the grafic user interface

I don't believe there is any difference but I would suggest you go to Polk Audio's web site to verify. It could just be a name change on Amazon's site.

I was confused by this, too. it looks like the MP141 (cube) is indeed different than the cylindrical speaker. At the ianker site:cube: http://www.ianker.com/product/99ANSP9901-BSAcylinder: http://www.ianker.com/product/99ANSPKER-BMAOn The cylinder page, scroll to bottom for tech specs and it says: "Speaker Output Power: 3W × 1." That's 1W less than the cube MP141.

This newer version includes a delayed output relay to prevent loud speaker pops when the power is turned on / off. Also, some of the older units were sold with power supplies that couldn't quite supply enough current to provide adequate power. I've heard the newer power supplies are better. There's probably some other changes that I'm not aware of. If anyone can elaborate, please do.

If you have an existing DAC, I'd suggest looking into the Audioengine A2 original version.Differences between A2 and A2+:USB digital-to-analog converter (DAC)Variable audio output (connect a subwoofer or wirelessly send audio to other speakers with our optional W3 wireless adapter)Upgraded speaker connectorsStandard 1/4" threaded inserts for wall mountsUpgraded power supplyUpgraded accessory cables

No You won't see a difference! This speaker is excellent and worth the money you're good to go!

Better. No comparison. 3000 is a solid unit, hassle free. But that unit is old,there are other options in that price range now... check out the numark. Or see if you can find a used m audio xponent. Owned that one for years.... way superior to either.

I have no comparison. Albeit, should have purchased amplified when you compare prices. Although when I purchased it I did not know the amplified was available.

Hi Jim, I really can't speak to the specific sound differences, I can say though that the Polk has a nice, tight punchy bass and I have been very happy with it's performance

Follow this link, it compares both models and explains the pros/cons clearly. http://www.kitchenaudition.com/?page_id=2320

I have no experience with Marantz products. By looking at spec., the only real difference I see is the wattage per channel. This one is less by 45w. Few other minor differences but generally the same.

They're basically the same, except with a (built in) lower cross-over point from mid range a high range. So, these (depending on how you look at it) are either "bassier," or "have less treble." Although I believe the cross-over point isn't much different. So essentially the same speaker.

No difference whatsoever. I have purchased many of these for gifts. Different colors. Those that have them, including me (I take on the road).....all love them. It is a great portable speaker. If you are looking for something more substantial...try the KMC 3 in purple...which may be had for about $200 and is an absolute steal at that price.

Differences between the A2+ and original A2.USB digital-to-analog converter (DAC) Variable audio output (connect a sub or one of our wireless adapters) Upgraded speaker connectors Standard 1/4" threaded inserts for wall mounts Upgraded power supply Upgraded accessory cablesIn my opinion, not worth 50 bucks! I have been using my A2 everyday in my office, and they have been extremely durable! Hope it works.

there is no set standard for rating watts, I have sold audio gear for many years, if you go to onkyo's web page and look at specs, you will see different numbers for different ohms and frequency, all manufactures do this. Very expensive amps will double there power into four ohms, but these are in the thousands of dollar range. The size of the power supply is what really makes a difference. If your speaker package is under the $2000 price range this should be fine, I bought this for my sons system.

I really haven't noticed a big difference. It may mute the volume a little. I don't play music on mine but use the speaker when on calls a lot and that volume has okay. I really don't have any complaints. I had the Razzr Max for the previous 2 plus years. I love long lasting battery's. I' very happy with the larger battery. Hope this helped.

John Z., I purchased a 9460 because I have a 9400BS at work and love it. Both they units have a longer microphone boom with a foam tip.
