  • Peavey Mfx-1, Mb-2 , Fh-1 help.

    In the old days I used to own SP1 and SP2 cabinets. I ran one cord to each side and used jumpers on the horns. I just bought the speakers listed above and it came with 3 cables for each side ziptied together. How do I hook this set up into my rack and why? Thanks in advance.

    They did come that way ... but it wasn't a very good way to do it. Not much in the way of networks there.

    They should be tri-amped but it adds costs. Or you could design passive crossovers.

      I asked a question before I found the site ( yorkville.com ) I guess I am going to run from my non powered board into a three way crossover and then to 3 power amps. One for each ( high, low ,mids ) and that would explain the three cords. It sounds like a good way to do it. I will be using 3-1000 watt amps. Thanks for the response.

        Things to know about the system. The first horns had a 20 watt rms rating.
        The subs are more a Mid-sub. They run from 59hz to 250 hz. You will want a low cut filter set at the 50/60 hz range. If you run the sub lower than 59hz or so it will unload and make poping sounds. This could damage the driver.The Midrange as well should not go lower than 250hz. The sub can be crossover as high as 500hz. If you run the midrange below 250hz you run the risk of unloading the driver and maybe causing some damage. The crossover points were 250hz and around 1.2k for the system if I remember right.
        Also the sub driver is reached by removing the bottom plywood sheet on the box. There is a foam double sided tape that seals it to the box. Be sure to see if the foam is still alright. If it is leaking this could cause some problems with the box/driver combination.

        This is a very loud horn loaded system. It does have a limited low freq response. If you have the $ for a digital crossover I bet if the system was setup right it would perform well in its designed range. I had one for some time and it served me well. I used the peavey Crossover Mainframe with a PL-250hz and a PL-800EQ crossover can crossover system and it worked pretty well with a little eq tweeking. (The horn could be used as low as 500hz in lower power setups)

        My best advice again would be to use a 50/60hz low cut on the subs. They do thump hard in the 60 to 150 hz range.

        Let us know what you think of the system when you have it up and going.

          Ah, yes, the old Peavey 'Project' series; I think those were sold as a the Project 4 system. Saw a lot of those banging around medium sized gigs in the 80s. I remember a band in my high school auditorium (500 seats) ran two stacks of these per side!

          Peavey used to have a neat system with these where you would drive them off CS series amps each with a suitable plug-in crossover module plugged into a socket on the amp. Usually CS-800 for the lows and mids and a CS-400 for the highs, if memory serves correctly. The modules looked like little silver cans, but these cans were tweaked for specific systems and made setup easier as they handled crossover and basic corrective EQ for the cabs.

          Those are old cabs and need to be driven carefully. They won't take as much power as some newer amps can put it, but they can very loud on not a lot of power.

          I hope your set came with a roadie, as those monsters are heavy!

          Oh, post pics of those cabs! I'd love to see 'em.

            My first band bought a set of these. I remember riding home in the back of a borrowed pickup picking the cat hair out of my mouth.....the giuy who had them had cats living in the "shelves". Never could keep the hf diaphrams from blowing. Once we upgraded to p118's the bass player used one of the fh1's for his bass rig....the good ol days!!!

                That depends on your perspective! Unfortunately there just doesn't seem to be anything commercially made thats as good overall (Quality and quantity of sound,flexibility,portability and price) as The Peavey Project 2 for the working musician!

                P.S. Dookietwo, excellent post there on the optimal setup. Thats the way I remember it too!

                I actually found this forum while looking for plans for Project 2 's. I am still looking for good plans BTW!

                  Really? You might want to get out and see what's available. Quality of sound and portability were not their high points by any stretch of the imagination. They made loud noise and lots of it.

                    Yeah nothing says portable like over 250 pounds a stack. Not counting the amps. I had some Fh-1s and the MF-1s back in the day. I remember stuffing a bar napkin behind the metal nameplate on the sub to keep it from rattling.

                      Unfortunately what I had was not Project 2s. I had a pair of SP-1s. SP-1s are FH-1 and MF1x cabinets from the Project 2 series.They lacked the MB2 mid bass cabinets.

                      I did have the opportunity to do a direct comparison of my two SP-1s to 4 Klipsch Lascalas!
                      My SP-1s thorougly outrocked the far more expensive klipsches!!!!!

                      The main trick with SP-1s was not to run them below 60hz. run correctly they were good sounding and very potent!

                      If you had some making noise you might want to check the setup !

                        I'd say Andy (Aged Horse) knows more about any setup both you and I know on his little finger nail.

                            No need to check them out, I serviced plenty of them in the "good 'ol days" and compared with what's available now there is no contest at all regarding sound quality. The mid level stuff today stomps on that stuff in sound quality. Just stomps.

                              From 60Hz to 16kHz there are very few cabinets in existence as efficient as those Peaveys were.
                              For multiple grand more you can get close to what you could do with a pair of Project-2s and some good subs.
                              By the time you add in ALL the extra cabinets and power amps your no longer more compact or lighter,and your electric bill went up dramatically!

                              I also have a Question for You Aged Horse. Were you dealing with early models? It could make a MAJOR difference. My SP-1s were late model and had the Anti bump plate in the LF horns. Early SP-1s and to my knowledge all Lascalas of that era lacked this feature.

                              As to the potential for a re-issue of a modernized version from Peavey, we can always hope. After all Klipsch already has put Lascalas back into production. They are an improved version too! The feature a 15 inch LF driver ( Like the Peaveys did) as opposed to the old 12s that originally came with Lascalas. At $2999.99 per cabinet list price I am not a buyer though!
                              Before you dream can come true, you must dream it!
