Single driver full range speakers

Hi,
I am a simple home hobbiest. I've built an great sounding full range single speaker set (so no cross-over,, and that's the point. I don't want a x-over).
But of course it lacks terribly in bass. Is it possible (is it commonly done?) to add a woofer into the cabinet with no cross-over (again, simple straight wire to amp). Would it require wiring in parallel or series?

Currently each speaker has one TangBand W8-1808 full range 8" driver and sounds very good.

Thanks in advance, I really would like to know if this is possible (safe?) to do.
Rob

I bought a pair of German Physiks Unicorn II speakers a few months ago. They are the ugliest best sounding speakers I've eve owned, and I've owned quite a few. The omni-directional DDD driver is something to behold. The bass reproduction is fantastic, so much so that I sold my pair of Wilson Benesch Torus subs as well as REL S/10. This is the closes I've come to a live event.

Why don't they offer more single driver speakers?

It is not easy to manufacture a single driver speaker to properly address the unique demands and challenges inherent in this topology. Prior to German Physiks, I tried Omega and Ohm at home. I listened to Liisong and MBL in my friends' systems. With the exception of MBL, the other ones had several shortcomings that I just couldn't see myself living with in the long term. German Physiks Unicorn changed my mind about single driver speakers though. Not only is it the best single driver speaker that I've owned, it is THE best speaker that I have owned to date regardless of design or price point.

absolutely is done.  My Ref3A DeCapo I speakers are two way and use no crossover, just a high pass cap on the tweeter.

the trick is to find a woofer that rolls off as a good match to where the tweeter begins to come in.

You could also make an effort to time-align woofer and tweeter if you are a diy builder.

I really like full-range speakers with lightweight and additional whizzer cones, but they lack the deep bass we are used to from “standard” speakers. There are back loaded horn designs that improve the bass somewhat, but they usually cause other problems. I have been working on this topic for almost 50 years and have tried and listened to many drivers and designs. 

In the end, I developed a completely different approach. A: The driver must have an electromagnet and B: There must also be a large diaphragm for the low frequencies. Perhaps the effort involved is too great for some, but listening to music with the Wolf von Langa London really gets under your skin and gives you boundless pleasure! At least take a look at the speaker; in the US, Colin King (Gestalt.Audio) may be able to arrange for you to listen to it. https://fieldcoilloudspeakers.com
