Fullrange with 10 inch woofer?

[Starre]

Is it possible to make a good speaker with a 10 inch woofer combined with a full range unit? The goal is to reach 20Hz with that woofer and avoiding a 3-way using a full range unit on top. It will hopefully make the crossover easier, only one crossing point needed.

That's essentially a FAST system, it's been done quite a few times.

Yes there are many similar systems but...

...do you really need 20Hz?

Who doesn´t need 20Hz , would be nice!

Thank for the links, I will have a look.

Find the FR yourself. There are many available including the experiences with "Das Viech" with the Beyma 8AG/N full range driver of bubuxxl@diyAudio
Visaton Stella - any thoughts?

Then you only need a good woofer to go to 19/20 Hz with a 90/100 Liters enclosure for that purpose, no problem. Also look at what is your objective in terms of SPL of the FR.

Another thread on the subject -- it will lead you to 3 more eventually.

I'm currently listening to such a system. EL70eN + 2 x EL166 per side.

Thanks planet10 and Inductor, I think the answer to my question is a "yes" without hesitation.

I'm not the expert, but my only concern would be when I read the following:

"The only negative aspect i've found is that an underhung fullrange driver has usually an even smaller voicecoil than a typical 1" dome has, and no ferrofluid to cool it. So you get thermal compression problems pretty early on, especially combined with low efficiency."

I'm still debating whether I should add woofers to a pair of full rangers I have.
