Default Full Range Speakers Wired in Series?

Can full range speakers be wired in series? I just ordered this low powered digital amplifier for a boombox project, and was planning on connecting one 8ohm pr. of TB bamboo cone full range speakers... but would 2pr per channel wired in series be better than one? I know "better" is subjective, I suppose louder would be my desired goal here (outdoor use). I'm sure amplification and enclosure constraints would impact sound quality, but I'm just curious if this can be done without sound quality degradation.

I've searched this topic pretty extensively and havenít found anything. I apologize in advance if I've violated forum etiquette... I'm a newbie here. Actually I'm a social forum newbie - this is my first post of any kind ever.

Welcome to the forum.

Well, they should work ok, but there would be a couple issues to keep in mind.

Two 8 ohm drivers wired in series would present a 16 ohm load to the amp. Wired in parallel would be 4 ohms.

There could also be a frequency response issue called lobing. The sound waves can cancel each other at some frequencies depending on the listening angle.

Would be preferable to just use a stereo pair. Maybe just go for a bigger pair?

Search for 'Boominator' to see similar projects. There's a thread about the 3116 amps too, you might look over there.

Have fun with your project!

Hi, there's conflict !
Alan's answers were good, sort of reading trough 3116 FAQ's ... ( I mean the Boominator's thread )
But there's also the Big Is Better current
<no conflict with the Pro audio sector<
which would emply a (minimum ) 8 " driver.

Godzilla's answer would be to use an <<<eminence alpha 15">>>
That's a whizzer cone.

Also a coaxial Pro-style, Oh I see...budget !?!
Things get serious when thinking of outdoor, because the power goes
mostly in the bass section, and bass driver power is based on " acoustic
coupling " where Volume of air displacement depends on the membrane's diameter and velocity, so driver's excursion...

Either the treble section needs "particular attention ", too.

Acoustic coupling might be seen as from another POV respect to bass.
The gas, air, plays a role too.
The moving mass of a tweeter -is much littler than the one for a bass trasducer
Oh, sorry, just a little deviation from the full range section because of the
"outdoor thinking", which leads to specialization of the differenct functions of the piece of equipments used.

So, in the end, I would suggest to invest in
1) studying
2) study a method to "cheat" that Acoustic coupling
I find simply stunning the effect of a 10" woofer in addition to a car
coaxial speaker -Yes! a piezo in the middle. This would imply the use of a passive crossover. Mixed 4 and 8 Ω might make a melodic sound, either

In the very end I would favour savaging a 2.1 pc system

Hi CroweMagnon,

My one experience with wiring drivers in series vs. parallel was with Vifa TC9FD. Putting them in series resulted in rolled off high freq--I assume due to additive voice coil inductance. Running them in parallel was more satisfactory in my case.

Cheers, Jim
