Do you think this driver would work well as the bass driver in the bass-modified 150? I hav a pair and its specs look good for horn loading (I think).
Thanks,
Bob Figlio

Hi Bob,

Can you give me the specifications of the driver (Qes, Mms and FS as most important ones to know).
Ciao,
Bert

Hi Bert,
Here is a link with all the specs:

Hi Bob,
This is a 10" driver! I do not think it will work with the modified 150 but it could be done with a standard 150 which has a smaller throat to achieve the desired results. I am not sure though, experiments have to be done with the size of the throat in combination with the bass enclosure.
For mid-bass only this should not be a major problem though.

Thanks, Bert,
I agree, but I only want it to go down to about 50 Hz.I'll probably do the cut and try method.
I use a Velodyne HGS 18 II rolled off at 48 dB/octave at 40 Hz for the really low end.
So the issue then is, do I use an ORIS 200 or 250 for the upper end. I still want to use either my EX4's or "AER" MD3's on the top.
Thanks,
Bob

That's is mostly the best way to succeed. Don't cut the horn too soon trying to create a bigger throat, do all the experiments with the enclosure behind the driver first. Making the troath larger will decrease the sensitivity (or "boost") in the lower midrange.
So the issue then is, do I use an ORIS 200 or 250 for the upper end. I still want to use either my EX4's or "AER" MD3's on the top.
With the 150 on the bass I would go for the 250. The 150's give good body and fundament to the 250's with the advantage to have a more free sounding mid-high range. The 250's also look more like the 150's but then schrinked..

How does the 150 horn on the woofer work? Does it act like a fractional wavelength horn or does it simply allow a better integration at the upper frequency range with the mid-range horn or both or something else?

It helps a lot to integrate and it is boosting the lower midrange (increased sensitivity). The driver's parameters and the size of the throat dictate the crossover frequency to be used. You'll need to create a linear lift up to that frequency which helps to EQ the rise more easy and also creates a steeper roll-off above the crossover frequency (mass roll-of).
You'll need some measuring tools which will save a lot of time though...

Thanks, Bert,
I have a full range spectrum analyzer and have spent a lot of time measuring and developing systems. It keeps you honest and, as you say, does save a lot of time.
