GM-
Thanks for your (many) posts which I've been reading here as I skulk about in the shadows...
I have a pair of AN10s (now residing in the 2.8II AN cabs) and a pair of AN12s as well (those sitting on the shelf).
If you could run those drivers through the same MLTL sim you did (above) for the AN8s, I will build (at least one, if not both of ) them and let you know the results. I'm reasonably happy with my AN10s as-is, but I'm looking for something 'better' for them. I picked up the AN12s on impulse, hoping that I could get decent bass without messing with subwoofer and such.
Regards
John
I built blh for my nirvanas. Design was for PHY but it seems to work well with AN´s too. These sound great with good recordings and tube amps. However my friend who is more into heavier music uses The notch filter of 206 solo and this makes for a great allrouder.

AN10 - don't seem like a rocker - has plenty of top end

hey GM - -here's a quick hand-held TS for stamped frame Super 10 - -tried to hold it steady and away from my body - -not sure good this is but might be ballpark - - if so then qts is higher than spec (?) can one get good TS in an 8x10x8 room?
An externally hosted image should be here but it was not working when we last tested it.
@GM: can you give me a resource to quickly understand how to make a project out of the specs you gave me?
@nelson pass: do you mean that the bigger models (10-12") are performing well alone in a OB?
@freddi: "AN10 - don't seem like a rocker - has plenty of top end". too much top end making it unsuitable for rock?
can anyone give me a starting point (thread/link/project) for a costeffective sub that wuold match the super 8" on openbaffle?
and also a starting point about building an amp to biamp the woofers?
i know i'm going off-topic a bit, but i would like to make some fast idea about which solution i can afford. my current setup really doesn't work. that is i'm living without music most of the time.

regarding AN10's top end - its very good - an issue might be balancing when listening almost on-axis such as the aggressive filter seen on this page (which might be overkill?) - - its best to ask other users

Thanks for the sims for the AN 10 and 12.
I'll get one (or both) of these built later this spring, and I'll let you know how they work out.
Thanks again!
Cheers

hey GM - -what Q's did you use for those AN MLTL sims? - here's another run on one of mine - getting vas by added mass method seems touchy - driver here reached my cold room temperature vs the first run above being warmer no SET/SEP for this.

More than one person seems determined that they can build better boxes than David Dicks. What I can't understand is why they haven't approached him with their suggestions, perhaps with a view to his distributing them on his website.
He's only an email away. Perhaps we could get him to contribute to this thread. Whatever your opinion of his boxes, he deserves some respect for getting the drivers produced.

you probably are right. he has been invited rightnow.
the augies are a bit an expensive option to go at 125$ piece from US, if i remember well MJK told goldwood were more than satysfing when used for bass support.
i found a really cheap gainclone, will 68w on 8ohm be enough to drive the drivers trough the crossover?
@GM: if considering only one sub to be in the middle what would be you suggestion? sealed, horn loaded, h-w frame? there is an interesting project on the Orions site for an open subwoofer, but i don't know what electronic the need... please give some more hints

Good idea, and I'm glad the invitation has been extended.wakibaki said:
David has always been helpful when I've emailed him.
re: Distribution of speaker plans on the AN website- Since the AN plans/designs are only available to folks who buy AN speakers (with a reminder from David Dicks not to share the details publicly), it would seem a bit strange to have other designers' work publicly available on the AN website. As long as everybody is happy, it seems like a good idea, though.....

since we spend so much time criticizing i too must say david dick has always been really helpful and incredbly fast with his e-mail support.
especially when i was building my first pair of diy, the minimonitors, he answerd any kind of idiot questions came to my mind...
and also it seems he is encouraging people selling designs trough his website
really i'm giving the 2.8 a try as soon as possible and i'll report in this thread
he also feed me with fidelio plans suggestion, but he wrote everywhere on his site not to go for a horn...
@go_sub3, before having them in the phy horns did you auditioned them on a CSA enclosure, can you give any comparison? would you share the plans for the horns?

for AN10, Les Hudson said he tried 22 variations and preferred David's reflex

You can go as cheap as the AN 6.5" drivers and the Eminence 15"
Alphas. Of course I spent the extra $10 for the betas, which have
a magnet 😉
As far as sharing details, In the past year I have undertaken to
measure all the FR drivers I have in a large open 4' x 6' baffle.
Having accomplished that, I cut the ob's down to 3' x 5' and began
the task of listening with appropriate woofers and active and
passive crossovers. The list includes Audio Nirvanas, Fostex,
Lowthers, and single pairs of other brands, the cheapest being the
Pioneers and the most expensive the Feastrex.
After a while this information will start being published.

really such a big box and driver won't go lower??
than OB with a woofer will be the only chance... it will also give some better highs i think

great to know Nelson, looking further for you works!
can you give me some hints on how do properly set-up a cross-over network? will a gainclone 68w/ch 8hm do the job? and t-amp/SET on the AN?
PS on first post i wrote
'1. Bassreflex: Minimonitr project from audionirvana site. simply no bass, too shouty.'
well, probably it was also my SI t-amp that couldn't give the design any justice... 🙂 (but it gave some really deep tone on the spiral) than of course depends on recordings and kind of music...
