This is John "Zaph" Krutke's Bargain Aluminum MTM. You can read about it here if you wish http://www.zaphaudio.com/BAMTM.html . The drivers are very effective and are listed in the link.
The sound of the speaker is very nice throughout with a rich, full bass and pleasant and extended highs. The 1 cu ft. cabinets have solid cherry fronts and black melamine covered sides. They are solid and sturdy, weighing about 31 lbs. each.
If you read Zaph's write up online you'll notice his cost estimate is lower than my asking price here. That write up was written in 2006. Unfortunately, prices have risen and my asking price is actually less than the cost of the drivers and crossover components.
If you are interested, come and listen and see for yourself.
