Yeah, give me just a little bit of time and I'll have the drawings done.

It wasn't a bad time for you to ask me about it. I need to get some of those drawings done. I plan to do a couple of different ones, and one with the sand filled area option. I just need more hours in the day.

Danny - Have you ever tried sand filling an LS? Would it make much difference?

I have not. I am sure it would make some difference but so does just lining it with No Rez. I wonder how much overkill is too much overkill? It is also important on these to keep the baffle width as narrow as possible, so it would have to be done in such a way as to not increase baffle width.

hi danny, not trying to rush you, just posting this as a reminder that you said the drawings for the design of the subwoofer box ,for the pair of 8 ohm version of the servo sub, with dual 1.6 cubic foot sealed chambers would be available and posted in about a month or so.

oh and to answer your query a dear friend of mine said that overkill is the least you can do

Danny Richie · « **Reply #27 on:** 4 Jun 2008, 08:22 pm »

I am working on them right now.

i thought about it while i was at work ,and i realise i was abit selfish innot trusting danny to post the drawings for the 2 driver version. my apaologies danny . i did notice 1 thing danny, in the original subwoofer topic. you said that these drivers would be able to fit in an 11 inch cutout. but the cutout in the drawings you posted arec over 12 inches.?

WerTicus · « **Reply #33 on:** 7 Jun 2008, 04:29 am »

that is the face plate recess size. if you cut a HOLE that size it would fall right through

afaik the cutout is exactly 11"

thanks werticus, that makes a lot more sense. i took a 2nd look and you were right. i need a vacation pretty bad

HI Danny, any update on the drawings for the 2 subwwofer cabinet?

Danny Richie · « **Reply #36 on:** 12 Jun 2008, 02:35 pm »

I might get a chance to get back on doing drawings later today.

If you can put two and two together you can pretty much get it from this one: http://www.gr-research.com/pdf/singleservo.pdf

Hi Danny

Is the title of this post true?

so if i want to do OB from 100hz and higher

i will have better bass ( 100hz and lower) than the OB bass with two of yr 16ohm servo drivers in their own OB?

Danny Richie · « **Reply #38 on:** 13 Jun 2008, 02:27 pm »

My thoughts are that if you are going to build box for the best sounding subs available then you need to make it really solid and nonresonant.

OB subs are a different animal all together and have a clean transparent quality that a boxed sub just doesn't do. The OB servo subs hit hard but don't load the room. It is clean and tight with great extension but doesn't knock anything off the walls. It truly is something special.

If you are already using an open baffle speaker then this is the bottom end you've been waiting for.

Danny,

How did you "seal the back of the amp from the inner air space"? It seams like it would be good to isolate the inner air with a nice solid dead no-rezed wall, but then maybe that would be overkill.
