Dayton Audio ST305-8 12" Series II Woofer
Is one cu.ft. really the best sealed cabinet size for one of these? How would sound be affected by increasing cabinet size by 50% to one and a half cu.ft. This would be for music and h/t use. Music being most important. How can I contact mainland?
Increasing the volume to 1.5 cubic feet will drop the Qtc to .585 and slightly lower F3 to 69 Hz. These will really work best in a ported design if you want decent bass from them. A sealed box will only have useable output down to about 40-45 Hz.

i have a 3.1cft tower im rebuilding what size port would i want to play around 30hz
I would recommend a 4" diameter, 8" long port for a tuning frequency of 30 Hz.

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.
