Hmm...
Brad is asking what type of speaker to plug into his projector amplifier and on that question, I have to go along with Graham and his advice.
As stated, most computer speakers would NOT work as they are "active" and have their own internal amp. NOT a good idea.
Back in the day of course many companies, such as Craven Instruments here in the UK made very solid single driver cabinets for use with 8mm projectors, so I understand where you are coming from Andrew. Well built, but with "restrained" frequency response which lent themselves well to general 8mm magnetic recordings.
Plug in and play...and certainly better than the speaker in the projector casing.
But, as Brad is asking, what type of modern speaker can be plugged directly into an 8mm sound amplifier 8 ohm output...???
Hmm...
Of course, the better option (which I think Steve and Andrew are talking about) is to take a line level output (or just maybe a lesser pre-amp output, as with an Elmo ST1200-HD headphone output) from the projector to an external amplifier and let that handle whatever speaker system you have attached.
Brad, what projector are you using may we ask?
If you can take a pre-amp output from your projector then you have a world of EQ and great sounding, er, sound opportunities. Any damage then incurred would be down to your amp & speaker set-up.
Personally, I have always achieved sound re-production from 8mm kit which never fails to amaze even myself as I know it is really pushing the boundaries.
Although I suspect we may have some discussion on this, which is more than welcome!

Indeed, Steve, so with an Elmo ST-1200, as you know, you need to take the two separate track monitor outputs to an external amp.
Then you need EQ, and then some POWER as those outputs are low.
Personally, I never had a real issue making my own shielded cables and whilst the output is low, a decent amp always seemed to cope.
Back in the day, The Lion King or Raiders of the Lost Ark literally made the floor boards shake (no kidding) whilst also providing great clarity stereo (with a little EQ balancing from Derann's, er, slightly tonally different tracks!).
Of course the Elmo was sometimes prone to wow, which could ruin the mood, something the Beaulieu doesn't suffer from.
On a re-recorded stereo print, the Elmo could even attempt Dolby surround. Wowza!
EDIT: I've run my Elmo through a Musical Fidelity Class A with Linn Helix speakers back in the day and...whoa! It even needed bass cut!!
Now the super 8 all runs through a Yamaha 5.1 amp with B&W speakers and a Krell sub.
Sounds great and I hope to soon upgrade the amp!
