Dayton Audio ST305-8 12" Series II Woofer
I have an older pair of cerwin/vega r-211s,will these 12" daytons st305-8series ll sound as good ?I have a twin powered harmon /kardon 750 amp to drive them
The Series II woofers are and have been very popular replacements for Cerwin Vega speakers for many years and are usually what I recommend for this type of application. I cannot directly comment on the sound but they have been very well received from our customers.

I own pair Cerwin's Vega E-312, the bass start to make a noise, (not scratch) I take out the originals and and they look cheap and not heavy weight. My amp has 125 rms/ch and I think maybe they need more powerfull drivers. Advice please. Thanks
It could be that your woofers are getting worn out. These Dayton Series II woofers are very popular replacements for that application and are highly recommended.

I need replace the 12" woofer on my CERWIN VEGA AT-12 and the one similar I have available is a 8 ohm. Since the original speaker is 4 ohm I need know if I can just replace with the 8ohm and sacrifice some power or maybe install 2 X 8ohm = 4 ohm?
The Series II woofer is a very popular replacement for this speaker. This will drop the available power from your amp, but only by 3dB. If you wanted to use a single 4 ohm woofer, the Dayton Classic 12" Subwoofer will also work for this application and is 4 ohm.http://www.parts-express.com/dayton-audio-dcs305-4-12-classic-subwoofer-4-ohm--295-204

how would this woofer perform in a vented cabinet with a volume of 1.8 cubic ft? If recommended, what would F3 be? What would vent length and diameter be? Thanks
This woofer will work pretty well in that volume. The tuning frequency will be slightly higher than "optimal" but it will still work fine. I would recommend two 3" diameter ports that are 10" long for a tuning frequency of 42 Hz.

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
