Dayton Audio ST305-8 12" Series II Woofer
With 70 watts of power, would these speakers have advantages over the DC300-8? They will go into ported 1.5cu ft cabinets. Also can I extend the 2.5in dia port tube with an elbow and extend up inside or reduce port diameter to tune the cabinet lower?
With only 70 watts there will be no real difference between these drivers in terms or tuning and output. The Series II will work a bit better in the smaller volume, but the audible difference would be negligible.

I need new woofers for my Sansui sp-2500 speakers (1.53 cu ft). The originals say 6ohm 25watt, and have an spl of 98db. My Sansui 7000 @ 70 watts rms per channel will be running these. Is this speaker a good replacement; other cheaper good candidates?
This woofer will work well, the sensitivity of the Sansui speakers is pretty optimistic. The less expensive Dayton Classic DC300 will also work well.http://www.parts-express.com/dayton-audio-dc300-8-12-classic-woofer--295-320

I changed my mind and want to put THESE 12s in my 1.65 cu. ft. box. What are the optimal port dimensions for this application?
I would recommend a 4" diameter, 10" long port for a tuning frequency of 40 Hz.

I need some help in replacing a blown woofer. I have Infinity SM122. Can you recommend a pair of woofers to replace my blown one. I would probably buy a pair and take out my good one so the pair match up.
Our best selling woofer for those speakers will be the Dayton DC300-8 which you can see below.http://www.parts-express.com/dayton-audio-dc300-8-12-classic-woofer--295-320

Could you look up the specs to the old version of this woofer?
I bought these many years ago, same part number, but the box lists different specs, but only a few. Mine has a 67 oz magnet, 93.4 db sensitivity, 29-3000 response, Fs:29 Qts: .34 Vas:7.62 cuft I want to use them for an econowave project, but it seems like they won't go low enough
I cannot find anything older than 1997 when these woofers were new. Unfortunately the specs then are the same as they are now. Are you sure it was this model?

Enclosure for F3 ~30Hz
....or what is the most optimized enclosure size, type, vent length etc. for music?
I would go for a 2.5 to 3 cuft ported with two 3" ports 15" long. This puts your F3 at 40hz, but 30hz is only down 2-3 dB from 40hz. With room gain it should flaten out the response so you should end up with good authority to the mid 20's.
