I'm going to guess the price never goes down.
On another note, I was searching (as I always do) for used speakers and came across some Dell/Altec Lansing ADA995 (5.1) speakers for $65. They were made in 2001 I believe. I did some research and the sub is rated at 38Hz to 150Hz. However, they are rated at 94watts RMS, and the enclosure made of wood and houses 2x6.5" woofers.
I really have no need for a 5.1 system, but I thought for the $$ I could always sell them if they turned out to not be very good. Well after hooking them up, I can say it was $65 well spent dollars. These are very loud, and sound really good. The highs are a bit on the bright side, but not too bad. They are brighter than my ACS 48's for sure, but the bass on these is absolutely amazing. A bit boomy if the volume is up too high on them, but otherwise they sound very good, especially at lower volumes. They also play the LFE with a lot more authority. The previously mentioned song sounds great on these, so despite the higher quoted frequency range, they play everything better down to that range. I played some test tones and without a measuring device I would say that 38 hz is where it starts to fall off. I could hear tones down to 30hz, but it was getting quiet at that point. All in all, I think a good buy for the money.
So what this tells me is that if the Swam M50W can play to 38hz, it would be an awesome set of speakers for music listening. I would bet they aren't as bright as these and would probably sound more full. I think I may still try and get some when I have some more $$ just because I think I would love the fuller sound of them. For now I have eq'd 12khz, 14khz, and 16khz down some which helped quite a bit.
Anyway, just thought I'd post what I actually did.
If anyone else gets to hear the M50W, please post your thoughts.
