Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded
Q on Ohm/oice coils Goodwood vs Tang
I am replacing 2 6.5 inch speakers in an old dbx soundfield 3x2 lower end unit. Each of the current speakers is about 6.5 ohms and 8 when connected in. Do I need 8 ohm speakers or is there a way to wire these as 8 ohm speakers per channel. I already ordered- may need to hold till I hear. Vs tang 8 ohm units. Going to use this as a subwoofer lite with monitor audio column 270 speakers.
From what you're describing, you would simply wire the voice coils on this speaker in series to achieve an 8 ohm load. If you look below, there is a customer review describing one experience with a DBX unit, using this speaker as a replacement.

how would this best be used ?
i am thinking about getting one of these and i am wondering in witch way to use it. NUMBER 1. should i have it down-facing OR. NUMBER2. just have facing on a side of a box. i would like to know what is loudest. Thanks :)
The issue regarding down-firing vs. front-firing is a matter of great controversy and debate. Realistically, it is highly unlikely that you would be able to perceive a difference between the two, as long as both are well designed and placed properly within the listening environment. One design technique will not necessarily be louder than the other, if all the other variables are eliminated.

Size of sealed enclosure
What would be the optimal sealed enclosure size for this driver?
.65 to .75 cuft

Could two of these be mounted in a sealed PVC pipe in a Isobarik loading. What would the length of a 7" pipe be. How do you think it would sound?
it would work but the results of more drive on the x max of the cones would not add much sound,, put your money on a subwoofer or a better amp to drive a single 6.5 in the proper chamber for best overall sound,, pvc is resonant... listen to the "blue man group" video and you will understand!

Ported enclosure sizing question
I am designing a stereo boombox and would like to include the option to run it as a 2.1 when I'm in the house. I would like both enclosures to be the same size for aesthetic purposes. That would mean the internal dimensions of the sub enclosure are: 16" x 7" x 5.5" yielding .356ft^3 volume. Some of that will be taken up by the plate amp, so let's assume the volume is around .325ft^3. I don't have the software or knowledge to calculate port dimensions, so I was wondering if someone could help me do that. It would be great if we could get the f3 in the low 30s but I understand that the task may be impossible given the price of this sub and my small enclosure. Thanks for the help. Hopefully I'll get a response and I can post this "2.1 boombox" to the techtalk forums.
That volume is quite a bit smaller than what is recommended so the tuning will have to be a bit higher. I would recommend a 1.5" diameter, 4" long port which will tune the enclosure to about 50 Hz. You could also leave it sealed and get a much smoother overall response.

Car audio use?
How well would these work for car audio application? I was thinking of using four of them. If this type of setup is possible, how much airspace do they require ported and what should the enclosure be tuned to?
If you check the reviews, you'll see that this speaker is quite popular for mobile audio applications. However, I would not recommend a ported enclosure, this speaker lends itself more readily to sealed enclosures or free-air installation. If you're building a new enclosure, I'd recommend something in the vicinity of 0.25ft³ per speaker, so four of them would do well in about 1.0ft³.
