DD is exactly right, too many opinions on that subject for some of us to actually say somethign abou it.

Not to mention I can't determine CAT5 from Gold Cryoed super conductive ultra linear phase coherent spliced twisted pair speaker wire.

The main thing you will notice is where the wire goes though.

I can honestly say running wire in the walls through exsisting 120VAC conduit is a no-go on quality control.

[quote author=Bob  link=1137542099/120#122 date=1139226968]..... I assume total ohms could be checked with a DVOM after wiring is complete, just before installing wires to amp or receiver? When we talk about a "4 ohm load", is this a measureable number, or is it theoretical? ...... Bob [/quote]

Sorry, Bob, I just realized you asked 2 questions. 4 ohms is real and measurable, not just theoretical, but more properly called "nominal". That just means that since they have to call it something we can all agree to call it 4 ohms. It will only measure an actual 4 ohm impedance at certain frequencies while operating, but it can vary widely at different frequencies.

If you put you meter across the speaker terminals you will not measure 4 ohms. Your meter alone, without some other equipment hooked up also, cannot measure impedance. You will get a measurement of DC resistance, which is usually a little less than nominal impedance. If I was going to make a SWAG it would be around 3.2 to 3.6 ohms measuring with just an ohm meter for a 4 ohm driver load.

Good SWAG Dawg, it's actually 3.1 Ohms measured at the terminal connectors on the enclosure.

Have pictures scanned, but for the life of me can't figure out how to get them here.....

Used about 30' of 14 guage romex to sub in back of room. Seems to work ok using my highly trained ears lol  ::) Roll Eyes

J_Rock,  what did you mean by ...." I can honestly say running wire in the walls through exsisting 120VAC conduit is a no-go on quality control. " ??

Are you talking about running romex speaker wire next to a 120v romex? If so, I understand how this would be a bad thing.

Can anybody HELP ME get the  :o Shocked pictures on here !!

Thanks  ;) Bob

yeah, any time you have speaker wires running near a large alternating current, probably a bad idea, so don't go into the walls next to the power wire.

For pictures, I use Photobucket, but www.tinypic.com is nice.

Just upload the picture from your computer and they will spit out a link for you, copy the one that looks like:

[ i m g ] http://whatever [ / i m g ]  (no spaces.)  
-paste it in the post: that will put the actual picture in the post.

Otherwise, copy the http:// one and paste that into post for a clickable link to the photos.

It's actually very easy, Bob. First you will need to have them hosted on a server somewhere. I have used Image Shack before. It's a free service and there are many others available.

I always resize them first to 640x480, but slightly larger won't hurt as long as it's not too wide to fit on a standard page.
Open the host website, browse your hard drive to find the pics, upload them, make a note of the URL, or just drag-n-drop. There will be several options. I use the direct link to the image, unless I need to show a hi-res. In that case use the thumbnail option.

Open a message/reply box, use the buttons above the smileys to quickly enter codes that work with the forum software. Click "Insert Image" and you'll have a set of brackets apppear. Place the URL of the hosted pic between the sets of brackets. Use the preview to make sure it's right. Posting lots of pics from your HD takes a while.

I have used IrfanView for a couple of years for quick image editing and correction when I want fast and don't need Photoshop quality, It's free, too.

All that sounds very involved, but after you do it a couple of times, you won't even think about it. Worst case scenario: hit the HELP button above.

MOD: I see J_ROCK beat me again. Can you tell how helpful we all are?

How helpful !  Damn DD.

You guys are terrific. Will check out those site. I've seen some that are just horrible / not user friendly. Viewing somebodys pics on some of these sites are a pain. Havnt seen image shack or tinypic. Seen photobucket before. Didn't know these things are free though.

Thank you guys very much...

Ok, got an account with "Webshots", uploaded the pictures. I can view them on the site, but they are not 'public' yet for some reason.... Maybe the pictures have to be 'reviewed' before they let they out for the public to see? You know checking for porn ?? obsenity ??

Bob

Does this work for anybody? Should be an album with 5 pictures.

Very nice!

For bracing the tw drivers together, what is holding those pieces of wood?

Nice job, Bob!
I like the way you braced the drivers together. You'll have to give us some closeups of that operation. Cheesy Cheesy Cheesy
Since we've already polluted your thread with unecessary blather (THE term of the day!), you need to tell us more about the webshots membership. I've often wondered if it would be worth doing, but I'm concerned about putting their software on my machine. I like to run a pretty clean box.
Tell me why you chose webshots.


MOD: ....... maybe it makes more sense without the typos .......

you said you were going to buy the dvc version of the dayton, right ?
the subs in the pic look like the svc version...
the dvc version has better specs if i remember....
http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=295-130 are you using these ?
