Fullrange speaker with subs

Hi Guys,

This site is such a great resource - particularly for a noob like me🙂 So thanks for that.

I'm starting out in this DIY hobby and the time has come for a pair of single-driver fullrange speakers.

The bass will be taken care of by two Dynaudio 18S subs.

I have two questions:

What is the most punchy fullrange driver? I've had a pair of single-driver speakers from Omega Speaker Systems and while they were transparent and great with jazz and the like, they couldn't boogie.

Are there any fullrange drivers that can?

And more generally: what does the size of the cabinet do, other than bass? Does a driver sound bigger and bolder and punchier in a larger cabinet?


Hope you can help🙂

Punchy is typically a strong, and sometimes a bit exagerated midbass & a bit higher say 60-100 Hz.

This is right in the range of the XO to the subs so could be a bit tricky. Having some overlap with woofers might be helpful, so both are contributing to the range you want.

This is a combination of driver & box design. Look at the Pensils, they have this kind of range.

The size of the box depends on the driver. There can be too big a box.

Thanks for that.

Those Pensils look great!

Regarding cabinet size: if I have subs from 100hz and down, can I really fill a large room with small bookshelf speakers? It just seems counterintuitive to me that a bigger cabinet doesn't make the overall sound sound bigger and bolder? I'm a complete newbie so my intuition is not something to rely on🙂
 
If you have subs below 100 Hz, you do not really need a large box. On the face of it a small sealed box with butterworth Q and an F3 (only usefiul as a number when we are talikng XOs) of at most 100 Hz.

But given you are looking for that punch, having the mains cover that and then having the subs adding additional SPL at those punch frequencies providing more of what you seek. If it is too much you can just move the sub XO down.
