In Reply to: RE: 15" Woofer for 2-way project posted by Joseph Crowe on November 04, 2014 at 08:26:08
I am ignorant when it comes to speaker design. Always said it was almost more art than engineering or science. So, please understand I am not challenging you.
Why would you go to all the trouble and expense to design a speaker with a 15" woofer with a design goal of only going down to 40hz. That is not much better than the Klipsch Heresy II that is continiously diced for not having any bass. I disagree with that position, btw. Classical designs such as Bozak, Jensen, AR, KLH and many others easily reached into the 30s. Why not design to that range?

It's the type of alignment that I'm after. I personally value better transient response in the bass. The trade-off is low frequency extension.
I still get good low frequency extension however, don't get me wrong. A tuning frequency of 40Hz will still provide output down to around 27Hz in certain designs. For example my brothers Altec 416 Onkens provide the following response even though they are tuned to 40Hz.
The measurement was taken with the speaker placed in the middle of a large room, so there wasn't much corner gain happening. But you can see it does extend down to 27 Hz.
Here is a picture of my brother's Altecs in question.
