MacSpeakerz by True Audio
It runs in Classic on a Mac, so you have to have a PPC Mac running Tiger (or earlier) Software was discontinued in 1998 so not very easy to get.
Still shipping for Windoz. About WinSpeakerz: Loudspeaker Design software for Windows, A shame.

Hi Derek, So the 1" difference is a big deal? Or is the neo vs. ferrite magnet? The 4.5" are not available anywhere so the issue is moot I guess. Have you heard the 3.5" HiWave they are currently offering?
I'll look at it. $5 is cheap if it works.
iTunes is stupidly inept. Doesn't/t recognize folders, will only work two deep on tags, rather restrictive on length of file name. My library is 75% classical and I haven't figured out how to make iTunes work.

Size of BMR's
I have heard the small Hi Wave BMR's that are in the $10 to $30 range, they are sold on line in the UK as well as the USA, to be honest I dont like them at all.
The 4.5 inch Neo is a gem of a driver, very different sound to the small ones or tghe 4.5 inch ferrite BMR.
Shame you cant get them in the USA, maybe one day someone will import them.
Cheers

update on BMR line array ( copied post)
Happy new year ( 's Eve!)
I am getting great results with line array's using 8, 12, or 16 drivers per channel using the 4.5 inch BMR.
Here are a few important points that took me a while to fully appreciate:
(1) DSP / Eq is a must. There is no way passive Eq / crossovers / notches etc can do it without hideous complexity, cost, size, and loss of efficiency.
As a minimum try the Eq in JRiver media (or similar VST host), or even better Blue Cat Audio or similar studio grade plugins, Blue Cat do great free plugins to start you off. Reaper, Fab Filter etc are all great to.
(2) For full range music with av / peak SPL's at around 85dB to 105dB, size matters...The Sd of the 4.5 inch is 60cm square, a typical 12 inch driver has an Sd of around 550 cm square...Eight 4.5 inch BMR's = 480 cm square, 12 BMR's = 720 and 16 BMR,s = 960 cm square.
(3) All my designs are "on wall" and use curved cabinets which curve back to meet the wall, this almost eliminates the baffle step issue. Plus it gives you "free" low and low / mid frequency boost. I have measured solid bass ( +- 4dB) down to the high 30Hz low 40Hz depending on Eq and number of drivers. It sounds even deeper than it mearures...!
(4) Comb Filtering is a non issue. Yes you read that right! In real rooms ( not anechoic chambers ) and on wall location, the 4.5 inch BMR line arrays simply flood the entire space with seamless low distortion music. They are dynamic, detailed and so supple & liquid its delightful and astonishing in equal measure.
(5) The smaller BMR's just do not have the ability ( Sd and power handling) to generate the SPL's and dynamics. You have to push them so hard they sound ragged and stressed.
Also the big ferrite magnets really obstruct the back wave and muddy the midrange. The Neo magnet versions are way better in this respect, so pure and natural, but they are way more expensive...
Hope the above helps.
All the best
Derek.

8 BMR line array pic
Hi Dynablaster,
Here are a couple of pics of of the 8 driver ( 4.5 inch Neo) BMR array.
In this version I went for a very cool look to maximise WAF!
They are 1.6 meters tall, 200mm wide and 140mm deep. On wall weight 10Kg.
I am building a new set of the 16 driver version (sold the first pair to a buddy at Christmas) which is 1,850mm tall 280mm wide at the back and has a 165mm flat front with curved sides blending into the rear. It's really slim, only 100mm total front to back depth, with the right grill / art work on the front it really will be cool!
It is going to be close to 20Kg weight so needs a good bracket to hang it on the wall.
I hope to have the new pair ready by end of Jan, just waiting on the CNC factory opening up next week.
All the best
Derek.

You might like this too...!
Hey Dynablast,
Sorry for the off topic but I just checked out your art page very cool...!
I think you might like some of my older designs, the Predator & Prey ( Sub / Sat combo), The Ovation ( two way) and the 3 way Finale and the Angels ( Acrylic open baffle).
Even the Ovation (pyramid) is quite funky! They were all made between 2004 and 2007. You can see them in various posts on this DIY site and various show reports and reviews on the web, just search Overkill Audio and the speaker names.
This Six Moons review shows some good pics at the start.

Hi.
Im probably a bit late to this party but:
Sealed box yields a roll off that isnt too great with the 3"ers I have (TB W3-1285SG)
Now the gallery is working again (thx Jason) I will post the vented response, if it is of any use to you
EDIT:
Here it is:
The volume 1.64 L is around twice the 'max flat' alignment volume for this driver (so not an optimum for this box) but it has a -3dB point of 100Hz as req'd. Ripple is minimal considering, and certainly less than the higher Qts drivers of this ilk e.g. A5 grey gen1.
vent dia = 25mm, length 46mm, Fb = 110Hz
In its max flat volume, the TB i show has an F-3 of nearly 200hz.
