Badge on the front says KLH 2...suspect they are Model 2's...
Use the search box at the top right and enter "KLH Model 2" including the quotes. You'll see some threads on them.

Thanks will check them out. I've never owned KLH's before so I wasn't sure if that was the model. Just picked them up from goodwill for $20
Lotsa info in these recent threads, centered on the larger KLH-1 of the same series.

Appears to me to be nice find at $20 with the bass computer. Nice looking line up posted above.
First time I've seen these, I wonder what that bass computer does? Not sure the OP got that with them either...pics only show the speakers. Is it possible to recreate that gadget?
These are early 80's models - - poly cones, rubber surrounds, PCB crossovers, nice veneer, built like tanks. I think the ABC (analog bass computer) is a fairly sophisticated device, and would take some real know-how to cobble together from scratch. I am pretty certain that these speakers can be used w/o the computer, but you won't get the deepest bass that these speakers can offer. Great deal for 20 bux.
Really curious about what that gadget does. Is it an equalizer like the Bose 901 has? Can't be a bass boosting servo feedback device unless it's wired into the amp's feedback points.

Found this on another forum:
"Those were introduced around 1980. The so-called computer was supposed to minitor the woofer excursions while applying bass EQ to obtain a flat low frequency response from a small speaker. The "computer" would monitor the input signal, which, if it approached a level that would cause the bass driver to exceed its output capability(s), the "computer" would alter the bass EQ so that this limit would not be exceeded. I believe it would dynamically alter the bass boost, both in level and frequency to accomplish this. I have a review somewhere from High Fidelity of this speaker. If I am remembering this right they played it at a number of different levels and found that the system's computer did a good job of changing the EQ as needed and that it was not noticible most of the time, requiring really unreasonable volume settings to get the system to sound bad."
Cool, thanks for posting.

Since I do not have the bass computer with these what would be a safe wattage to run these at or does it not matter? Does the computer just enhance the sound at higher levels?
I think you can depend on the original wattage rating even without the computer. As with all speakers, if you are playing them really loud you should learn the different types of distortion, listen for them and turn it down so as not to damage your speakers or amp.

Currently running them through a pioneer sx-255r so I'm sure they'll be ok on the wattage then. They sound really good glad I found them cheap too!
