i wish i could say i was surprised.

 

I guess you have the Dual 4 Ohm Sub now...
Any possibility of a photo of your modified enclosure?

Based on your experience, should I run two 10s, one in driver side, one in passenger side? If so, I believe both would be DVC 4 Ohm as to wire each in series then parallel them into a 4 ohm final load on one bridged channel.....or just run one which would be DVC 2 ohm wired in series as a 4 ohm load?

If I start with one DVC 2 ohm sub, I don't think I can add another at a later date. I think I would have to purchase two new woofers as DVC 4 ohm based on Van Gogh desired loading characteristics. (If I run on the same single bridged channel)

Will the SPL be different if I run one vs. two on the amp's same 500 X 1 bridged output? (I still want to run the Kappa Perfects on the other two channels...) (If this is even allowed...)

Do you think the eD will fit in both the driver and passenger side enclosures?

Is this ridiculous?

Thanks,
Keith

 

I will get a picture up tomorrow

The sub will work in both the driver and passenger side enclosures.

The SPL will definately be greater with 2 subs. Not sure what to advise you to do. I personally think a single 10" is plenty. But that is just my opinion.

I am hoping to get something sorted out with eD and my fiberglass guy on Monday. I leave for New Zealand/Australia on the 14th and will not be back until January 5th.

 

Yes, this was our man.

On a serious note, I would love to do a comparison on this sub. I will be able to compare against my recollections of RF HX2, JL 8W3v2, and now Alphasonik PSW 810.

William, you've got PM.

I agree with William that one 10" is plenty. Keith give me a call.

 

correct... if the VanGogh is only 4 ohm mono stable, you're going to have some severely limited options on what you can do sub wise. you'd have to buy new subs to change the number of subs you're running.

umm. that's VERY tough to tell. no matter what you're doing, if you run 1 sub at 4 ohms (2 ohm DVC in series) or 2 subs at 4 ohms (2 subs, 4 ohms DVC in parallel, then subs in series), you're still running a load of 4 ohms, which means the amp is only going to output 500 Wrms. so, you're either outputting 500 Wrms into 1 sub, or splitting it in half for 250 Wrms in each sub (total 500 Wrms). it really depends on the sub at this point.... how efficient it is, excursion, etc.

generally tho -- 1 10" at 500 Wrms should be more than adequate for most bass needs.

what's your final goal? hearing and feeling the sub? or are you wanting to get into the vision blurring range of bass?

 

ROTFLMAO!

i don't think Karl liked me...

 

Sounds like one 10 is a good start.

On the educational side of things..I just read my previous post and think I made a mistake, but I am not sure. If you have two DVC 4 ohm subs, would you wire each sub in parallel for 2 ohms then series the set to get 4 ohms...or...series the DVC 4 ohm to 8 ohms then parallel the set to get 4 ohms load? Will it sound different? (Just wondering....)

Also, I saw a JL 12W7 driven by a SoundStream VGA 600.2 in a photo on the 'Stereo Install Pictures Here' thread. See page 8 about 1/2 way down.

The 12W7 is rated at 2.47 ohms I believe. If so, the Van Gogh must be able to approach 3 Ohm loading sucessfully? (Or at least the 600.2 does...)

Just Wondering...

 

"ROTFLMAO!" ??? I'm behind again.....(No clue on this one)

Also, I don't think Karl likes anyone... .
I didn't ask for him, he just picked up the phone when I called in.
Do they have anyone nicer there?

Jim - What did I get into here???

This seems to be the amp from &*##.
(It sure is fun though...)

 

You would wire the subs in series @ 8 ohms each and then the pair in parallel - load on amp would be 4 ohms.
