Default super 10

i am new to this forum and have to say that i am blown away with the level of knowledge i have encountered here.
i am in the process of buying a pair of Audio Nirvana drivers, now the model is the problem...Super 10 or Super 12
from my reading of the post it seems that the Super 12 is a likely candidate for OB designs although on the large side.
as for Super 12 and Bass reflex....HUGE boxes
the Super 10 seems to be more frindly in the size department, but which is the more sensible driver?
Also can anyone send me plans, detailed if possible in building a Horn loaded or other type of box for the Super 10 drivers.
i understand that strong powerfull bass is possible if i use a exoctic box, and since i am handy with my hands, God bless my parents for that , i would really like to give them a go as i think i might be more pleased than the Super 12.

Tonytex,

I own the AN Super Cast Frame 10" and have the 2.8 MKII Ambience bass reflex enclosure that is listed on www.commonsenseaudio.com and the bass is great.

I listen to a lot of different styles of music and am very pleased with the way they sound.

I use a Kingrex T20U amp and FLAC audio files and it's the best sounding system I've ever owned.

I think you would be very happy with the 2.8 enclosure.

Also, you can call David at commonsenseaudio and ask him some questions about the different drivers and enclosures.

Default Update

Hello group,

I have finally finished the CSA 2.8 enclosure modifications.

If some cannot remember I was having some missing lower-end from my AN Super8s in the suggested 2.8 enclosure.

I have retained the basic original enclosure design less the following:

1. Placed felt on back side of basket; result - none really, it sounds about the same.

2. 8cm diameter reflex tubes at 9cm in length; result - fantastic with the SET amplifier but there is a little too much bass with the gainclone. The result is fantastic with the SET and the vinyl collection.

Now I am happy with the results.

Thanks scottmoose - maybe you can repost the response curve with my above configuration? This way we can compare the theory with my result.

Line the top, back & one side wall from the top 45in down. Brace to suit, and it's a max-flat alignment, so adjust & damp to taste / your own room / system in practice.
I hope you are still watching this thread. As I consider buying the super 10 CF questions are rampaging in my poor ignorant brain.
This cabinet seems tuned at 40hz, what would one at 35 or 30hz look like? Would it still make sense or 40hz flat is the maximum reasonable result the super 10 can give?
Is there a tried & proven backloaded horn compatible with the super 10 that will give comparable results in the bass area?
Thank you very much.

Buondė!

what do you want to do with this project, what are the objectives?

I am happy with the normal AN 8" and think it is enough for a typical "Italian room". I have before in the past lstened to 10" fullrange but larger that 8" they become annoying - the sound is too strong (you can correct with filter but it isn't pure because there are signatures of the components). If you have a typical loud room (like here in Italy) I would not recomend the "Super" series. Take the "Normal".

If you are thinking of horn, this will occupy much space and is very heavy.

The cabinet is key to make any driver great. In bocca al lupo,
MV

I haven't stained them yet. I was to anxious to listen to them.

Here is something I did when I built mine, that you might want to consider. I used 2 pair of speaker terminal and wired the top driver to one and the bottom to the other. I wanted some options with this setup. Here's what it can do.

1. Jumper the 2 terminals and use 1 amp = parallel setup 4 ohms.
2. No jumper, 1 amp using only the 10"
3. No jumper, bi-amp, no active crossover required.


Thanks for the tip about editing my posts. I didn't know I could do that.

Hi, Greetings from India!

Glad I have come to your post wading through many many. I specifically wanted opinion on Audio Nirvana 2.8 ambience speeakers.

Now that you have spent some time with these speakers what is your opinion now?

Secondly between MDF and high density wood which one will you recommend for cabinet. I have this rubberwood panel in mind:

http://www.rubcogroup.com/pannel.htm

Thirdly I find the wide front Series 1 more elegant, will change of design make any difference?

Thoughts/suggestion from anyone else reading this would be welcome


thanks in advance

I really like the MkII enclosure. The MkII solved 2 weaknesses that the regular 2.8 cubic foot enclosure has.

First, the 10" AN drivers tend to beam. The result is the high end is weak when listening off axis. Since the MkII enclosure has a regular AN 8" on top, the high frequencies tend to be more evenly distributed as of result of reflection of the walls and ceiling. In most cases this will improve the sound. If you bi-amp these speakers, you can control just how loud the top driver will play allowing you to adjust to taste.

Second, the additional driver on top improves the bass. This is always a good thing. Also, the 2 3" port holes deliver much better bass than the 1 6" port. I've built both.

As far as wood choice, it's really personal preference. I wanted to stain mine, so I used birch. I have just recently finished staining them and hope to post some pictures soon.

I was told the wide version of the speaker will sound the same as the narrow version. Since they are both 2.8 cubic foot enclosures and use the same ratio's, I guess this makes sense.

I decided to stay away from the 10 and 12 inch versions of the AN. If you compare drivers, the cones get bigger from 8 to 12 but the magnets do not. So you've got higher moving mass with the same motor power = slower driver. Rise time is a major if not primary attraction of fullrange drivers. However if your goal is better bass and you don't wish to use helper bass drivers then the 10 or 12 might be perfect for you.

Thanks for your thoughts

In simple terms if I am using speaker on top I would better of installing a 8" Cast on front. Is my reading correct.

Thanks for the immediate and detailed reply. Answered many of my worries.

I am planning bi-wiring using this board:

http://cgi.ebay.com/Tripath-3-X-TA20...arms=72%3A1205|66%3A2|65%3A12|39%3A1|240%3A1318

The top speaker could be independently amped/switched of.

Further thoughts are most welcome
