It might have alot to do with it's location is his rom or office compared to yours. Sometimes location can make one of those cheapies seem alot more bearable in some respects.

This reminds me of a compact bandpass sub I once had. Uses something like 2 units of 4 1/2" inside I think. Can feel the air movement at the ports, but hardly any bass. Very disappointing.

Sold it to a friend who installed it in the cab of his truck and it actually sounded pretty good. Must be my room was too big.

About the Acoustic Authority (aka Cyber Acoustics) speakers:

Maximum PC tested their A-3780 2.1 system ($100) in March. To summarize, they sound decent (especially the satellites) but couldn't handle the tests. The left satellite blew first, then the right. They tested a second set that smoked, too. BTW they got a 3 (out of 10!) verdict. Boo.

I auditioned these speakers at Office Depot a few days ago and was hardly impressed. My father says the sub is boomy, even at low levels, and I must concur.

Stay clear...

I scored 12 Creative "subwoofer' out of a dumpster; they were inefficient & sounded like cr*p; (i think the plastic enclosure was tuned to around 75 Hz). I put 6 ea in a 50 L box tuned to 50Hz - they still didn't sound that great (surprise surprise). sort of OK for lower mids.

I think Stifa's best bet is to forget about trying to polish a t*rd, If he knows enough about electronics, he could pull them out of the creative and re-use them with a decent sheilded 6" woofer in a larger cab.

I've got the Logitech Z340 3 piece set 2 sats and a sub.
The sub gives very loud tight mid bass with is good but the satellites are awfully crap,no mids and muffled treble!
Surpised that a heavy duty 5 and 1/4 inch bass driver hidden in a sealed box with a 10 inch passive radiator in front of that,gives very good mid bass.
I think get the Logitech Z340 and throw way the satellites and replace them with Wharfedale flat panels [like i did] [the ones that look like picture frames] and it now sounds very good overall.

A pic of the Logitech sub and the Wharfedale loud panels!

You've got to admit that a bandpass PR system is quite a cool idea for getting deep bass out of a small enclosure/driver.

I'm not saying it's a good way to get that bass, but it's cool

I bought that same 3 piece logitech for a mate. I opened up the satellites and put in some cotton wool for dampin mats. Made sure also that the ports were sealed off as that impaired the performance. No trebble? did you try removing the little covers that will expose the drivers, this brightened up the performance no odds, never have a heard such a change when the grills were removed.

The sub exited one room mode so I eq'd that out with foobar and told the mate to always ure foo to play music.

I was also impressed by the bass that thing puts out. Oh and BTW i think its a 8" passive radiator not that it matter.
What the hell are you screamin' for? Every five minutes there's a bomb or somethin'! I'm leavin! bzzzz! Now with website! under construction.

Yes it is really boomy..

Im saying it isnt bad for the price, you can pick them up for 5-10$ on ebay.
