Hello and welcome.  What type of service do you need?  Crossover repair, driver replacement/repair?

To be honest I’m not sure (Novice here)
it’s cutting out and muffled at times. 
 

seems like during certain frequencies it happens. And then when I pick up the stylus and drop it again it sometimes plays back ok without issue. And then will cut out again.

Open it up and loosen and retighten all the connections probably just dirty connections. Easy to do. While you got back off it you could put a seal around the edge for the back panel. If your wanting to try soldering get some new caps. and replace those. Heresy is easy to work on and fix. Crites speakers has step by step pictures on how to replace caps.

As Rickate says

 

After if you are a handyman, you can try to identify the fault: cut wire, tighten the terminals, coil of burned or cut membrane, damaged filter component, ...

 

and then try the repair yourself, for example if it is a solder you can do it yourself if you know how to use a soldering iron. If it is a membrane coil that is out of service, and after clearly identifying the reference number of the speaker, you can change this membrane, there are many tutorials on how to do it. A tip in this case change the mebrannes on the two speakers so that the sound is identical on both sides.

you would have to start by isolating the problem -

 

 

1)could be the amplifier cutting out due to clipping  , lower the volume --- if you have A-B   , switch B-A  -- re-test , if you have a 2nd amplifier - check to see if both amps do the same problem

 

2) check the wiring , to the amplifier --- and the speakers -----  disconnect ---------make sure that the wires have good connections , if not , cut , splice and make new connections -

 

3) open the 2  Heresy  speakers wooden back covers with a screwdriver ----------and test with a multimeter the readings of the  tweeters ( 8ohms ) the mids ( 16 ohms ) - the woofer 8 ohms -any really low number means the diaphragm need to be replaced or the woofer voice coil is shot  (  K55v mids  OR k77   tweeter diaphragms ) 

4) check the wires of the crossovers to the speakers , then check to see if the wires are screwed tight on the barrier  metal strip  -------  if not tighten -

 

there are simple tests you can do on your own
