Summary:
I got these on ebay because I thought they looked cool. They had plenty of drivers of varying sizes in a somewhat logical arrangement. The drivers were shiny. I thought - how bad can they be? Well the answer is... fairly bad. The main problem stems from the highly resonant enclosure, which does not seem to be damped or braced at all. This results in a very colored sound that is best described as - boxy. The highs are OK but not prominent, the bass is quite full and smooth, mids are present but not accurate (high mid seems missing, low mid is muddy) so overall not bad but it sounds like all of that has been placed in a medium sized particle-board box and then a blanket has been placed over the box. As far as the soundstage is concerned - the soundstage is a box that is sitting right between the speakers. There is a blanket on the box. I cannot imagine what speakers the first reviewer had in his posession. They must have come with a bottle of cheap vodka because that is the only way anyone might have confused these with Polk or JBL or anything else for that matter. White van all the way.

Strengths:
Pretty good bass actually. Look quite impressive. Lots of drivers for the money, if that's your bag.

Weaknesses:
They sound pretty bad basically. I have no idea what to do with them.

Similar Products Used:
JBL S26, which is thankfully not similar at all. Can't really say I've used anything similar to these, except for boxes, which I use quite frequently.

Summary:
When I pulled these out of the box, I couldn't help but notice the hollow, drum like sound when my hand accidentally brushed one side of the thinly veneered cabinet. This is not a $1200 speaker...luckily I had only paid about a hundred fifty bucks, but I still felt as if i had bought speakers from the back of a van in a parking lot.
The sound is just awful for Hi Fi listening. I can see these speakers MAYBE being good rear channels in a surround system. No soundstage, imaging was flat, cabinet resonance was audible, and seriously, they just sound like what they are: Best Buy low to mid level mass market audio trash. Well, good for a high school kid or a college dorm with crummy acoustics I guess.

Strengths:
Price.

Weaknesses:
Build quality, sound, presentation, generic feel. If you're gonna start making speakers, why make so many and why so cheap? Just doesn't make sense. They really do suck.

Summary:
Owned more than 26 pr. speakers during the past 50 years and listened up to Aerials. Just got a pair of SDAT SB-880s. Rated at 4 ohms. Great clarity, definition, and balance. Good drivers, proprietary surround materials that speak well for edge damping. They have two 8 inch concave aluminum dome woofers, equivalent to a 12", in a ported cabinet. Although advertised with four 5-inch midrange divers, they actually have four 3 inch concave aluminum dome mid-range drivers, equivalent to a 6 inch, and two tweeters. The woofers and the mid-ranges are in D'appolito arrays, the two tweeters have phasing disks and are arranged side-by side. The most striking thing about them is the impression of no veil of any kind between you and the performance. The horizontal dispersion is outstanding. The instrumental detail is remarkably good. I can hear chafing bows, embouchure, the character of horns in a full orchestra, and piano is a delight. Stage presentation is about right. It is neither too close nor too distant. The same holds true for stage presentation in home theater. Moreover, they hold together down to inaudibility. They've been advertised at prices from $1600 down. If you like classical music,or opera, you'll love these. If you prefer rock, I don't recommend them. They're rated at 87 db/watt, so a 100 watt amplifier should drive a pair to 110 db - adequate for my 17 1/2 x 28 ft listening room. I use them as stereo and as home theater speakers. They are large - 44" tall, 11" square, and 59 lbs. each. Cabinets are very solid and well braced, nicely finished in cherry wood vinyl. The grill is exceptionally transparent, sheer material, which is acoustically transparent and almost visually so. You can get a pair for $265-349 from Mixsonic, Overstock, Essex, and others. I think all of these outlets have at least a 7-day return policy. Don't let the low price throw you. SDAT is a chinese OEM supplier to other speaker manufacturers. I think that when the word gets out, these will be more sought after and more expensive.

Strengths:
Clarity, definition, spectral balance, build quality, appearance.

Weaknesses:
None that I can find.
