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.

Closest thing that I think might satisfy is a JBL D130a 15" speaker from the '60's.  It features a concentric aluminum dome mid-range that also extends to give acceptable treble out to about 13,000hz.   There is no crossover (except mechanical) at all.  Of course you have to build or buy a cabinet custom made for the large speaker.  You might want to compromise.....JBL also made a 12" version but I can't remember its model number.  B

Thanks Ralph for pointing out to doppler effect, which definitely will cause phase mods of higher frequency by low frequency program, specially if spkr membrane moves significantly! For single instrument, like acoustic guitar, that may be natural! 

I would say there is zero chance a single driver speaker can out perform a quality 3 way. See @atmasphere post above. 

A JBL D130 and 130A were two different speakers.  The D130 had the aluminum dome and the 130A didn't.  The voice coil material (copper vs aluminum) and baskets were also different (130A is deeper) and they are not compatible unless you want a Frankenwoofer.

The 12" version was the D131 or the D120F.  A D131 will have a tighter voice coil gap than a D120F.

There were also 10" and 8" versions with aluminum domes
