I know I can safely say that nothing was further from any of our minds -any comments and questions are welcomed by us all. We're just enthusiasts, helping each other when we can.

Re the Ciare Oliver, it looks fine to me. Fs is a little high, but no more so than some of the smaller Fostex or CSS units for example. It should perform well enough. I'll run a few numbers when I get chance. Not a manufacturer I've looked at properly I have to admit, which is a bit remiss of me. There's some 8in Fostex dims that should be emerging on the BIB pages soon too, to go with the 8in Audio Nirvana dims & sims already posted. Lowthers are still in the works I'm afraid. Please accept my apologies for the delay (Jeff in particular for your patience) -they're being a bit of a pain. I believe GM is going to have a crack too when he has chance. If anyone has any other driver requests, new, or if I've missed any earlier posts, give me a shout and I'll see what I can do.

Regards to all
Scott

It’s been so busy at work… I own a computer consulting business for the last 10+ years and working on a new marketing strategy is not as easy as I thought it would be… visiting clients to get quotes (both positive and negative) trying to figure what we do well… and not so well… collecting all the info and balling it up so new prospects can relate and find common ground with who we’ve worked successfully with in the past. I won’t bore you any further with this tho…

>>> dims for a fe126e…
click here and scroll down for dims and sims…

BIB for FE126E/127E
L = (Line length) 97in
So = Driver 19.5" down from sealed end of cabinet
Sm = 43in^2

http://www.zillaspeak.com/bib-fostex.asp

I’m basically building this cab for the TB Bamboo which is very similar. I can swap out the drivers (must make a removable front baffle since hole is not quite the same).. and see which sounds better.

Tangband 1320SB 4" Bamboo full range
L = (Line length) 100"
So = Driver 20" down from sealed end of cabinet
Sm = 38"^2

I will post the 8” Fostex dims and sims early next week. Cool alternatives to the more difficult back horn recommended enclosures from Fostex and perhaps even better sounding!

Thanks Scott! No rush on the Lowthers… but I must admit I can’t wait 

I have modeled BIBs with Ciare HX160 in Hornresp and got the claimed results, especially when radiation into quarter space, read: corner loading is done. Responses are smoother without throat chamber, read: no offset, mouth area close to Sd. I`m going to simulate Acuhorns soon.

Greets, Oliver

For the Ciare I get the best results when the length of the horn is half of the wavelength of the driver`s Fs.
We would have two very simple rules of thumb if this (and throat area=Sd) could be verified for many drivers.

I brought these up awhile ago.

Greets!

Hmm, I thought I did these already, but if I did I didn't save it. Anyway, it looks fine in the 'stock' BIB. Its specs looks almost too good to be true, especially at this price, so probably is.

Anyway, anyone have any experience with this driver and/or their 'Ella' amp?
