Anyway, if you build either I'd appreciate some feedback:

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 ANs 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

in big Karlson -- excursion is reduced even compared to tuning the reflex higher

Z -- K15 with 30.5 sq.in. vent

K vs reflex (tuned around 41 = "too low" imo)-

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?

@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
John
