Newells book while very informative leans heavily on larger commercial rooms, that is what he built his reputation on. Curious what drivers your thinking for the studio system? If you have any recommendations for sources that are more focused on home studios than Newell, I'm all ears!! I figure I need to at least read up on the subject before a) launching a barrage of annoying questions here and/or b) starting to build prototype mains.
I'll be testing a candidate subwoofer driver in the next few weeks, but would rather not say what it is just yet.
Still haven't even decided on what configuration to use for the mains yet. The current front-runners are coaxial and MHM (mid-horn-mid). Driver choice will get narrowed down once I think I've figured out where the goal posts are. But price is a consideration, which unfortunately rules out Volts!
My R&D projects tend to stagger along in fits and starts, as I keep having to go back to doing other things that pay the bills.
Finding a real book beyond "put up foam" based on small rooms other than what you have already read is as far as I know nonexistent, realtraps has some good but biased articles on their site. I think the problem is other than the basics of construction rather hard to tame without some study of the actual room and no expert wants to put his name on something that will be taken by many as method rather than a theory! If I end up with an extra 2149 I will try to arrange a loan! Take a look at the new 2in mid ! Would love to try it with A Transducer Labs tweet and a BM220.8 in a Volt 3 way nearfield, ala ATC SCM25! |

Thank you Eric! I'll spend some time at RealTraps' site - looks like at least one of their videos is aimed in our direction.
What you say about no expert wanting to put his name on "how to treat a home studio room" makes sense, because if Augspurger is correct, apparently individual small rooms tend to have minds of their own.
I see what you mean about that new 2 inch mid. Very nice! Philosophically I lean in a different direction, but if I need to change directions, that mid is high on my list. And I'd hate to outright copy someone else's idea, but your suggestions for woofer and tweeter look really good too!
What's a "2149"?

Man some day I'll remember model # meant this puppy 2549 www.voltloudspeakers.co.uk/loudspeakers/b2549-10/My understanding is this is a variation on what was used for years in The bigger REL subs before REL went aluminum cone! Unfortunately my wife says we need to down size so I will lose my workshop space so I won't be doing much speaker development work plus either the Magnepan MG3.5's or the TAD / Augsperger clones are headed for storage 😪 |

Four of them would be... even more beautiful... and even more expensive... Thank you for the loaner offer but I'm using a less expensive 10" woofer in my Swarm that still gives me pretty good results.
Sorry to hear you're under pressure to downsize and will lose your workshop space. Workshop space is cheap therapy for us guys. We need to create or we stagnate. This thread is a way for me to keep my creative juices flowing.
I love Maggies, have owned 5 pairs and wanted to become a dealer for them years ago (didn't happen due to a fire). I have admired Augspurgers from afar for many years, but have never actually heard a pair. Imo they look like intelligent designs. I used 10" TAD woofers for a while before that model became unobtainium.
I'd be very interested in whatever you'd like to share about your Augspurger clones!
