OB with AE IB15

[tinitus]

Hi,

Does anybody know anything about the quality of the new AE speakers, in general or especially the IB15

4 x 15" woofers at 100USD each doesnt seem much

Drivers seem exstremely well designed but say says nothing about build quality or quality control

Shipping and taxes is a lot and its a very long way if just one driver would have to be returned...hopefully its not another "Hemp-story"

I bought a pair recently and they seem very nice. Haven't tested them yet though.

Thanks
Yes, they do seem serious with measurements and such, but not a lot going on on their forum site
Semms to me that they were made already in year 2006, so they may be "leftovers", hence the bargain price
I have mailed them about shipping but no response yet
I do plan to order 4 drivers fore my future OB

They are built to order, there is no "old stock" of any completed driver. QC is about as high as it gets IMHO.

OK, sounds good

btw...does that mean that "specials custom version" is a possibility

Yes depending on what you want. I am not the one building them anymore but John will do whatever people are willing to pay for. I once had a guy go through the backplate/tyolk stash to cherry pick the best 20 for his tower project that had all the motors facing out. He then polished them and had some serious chrome plating done. Gave them back and made some seriously pretty speakers from the back side.

Is the frequency response available anywhere? The link to the PDFs folder throws an error for me (Firefox).

Well.....

It does have a nice low Fs and almost ideal Qts for OB. But I hope you plan to throw a lot of power at it. 86dB/Watt? Not my 1st choice for OB.

With the Open Baffle losses, you're going to need tons of power.


Looks pretty, tho.

1. Hawthornes Silver Iris Maggies are around 88db...used with what main driver...97db ?
The hard facts are that even a high SPL pro woofer wont have higher SPL at sub frequencies...its all relative

2. I plan to use 2 x IB15 each side...I expect that subs will have to be attenuated in relation to mid/tweeter

3. I would never use an OB speakers fore playing loud...these are intended to be used at moderate levels, power should be no issue

4. I have another project which will use 18" PRO woofer, 12" midwoofer and a CD/waveguide

These would be very very very close to what you will find with this driver:
