![]() Then, hopefully you'll have a nice idea of what size cab you want, ie.212 or 412, and what type of speakers give you the tone you want, ie. So, FWIW, I would suggest taking your head to a bigger store like GC or Sam Ash, tell them your interested in a cab to play the head through, and go to town! You are NOT obligated to by something from the store, just because Joe Salesguy makes you feel like you owe him something for helping you out either. This is to me the cheapest way to go, but then, I keep changing speakers, and now I'm at about $450. I got some WGS speakers(Veteran 30's and ET-65's) X'd them, and I had about $300 in the cab total. There are also nicks in the tolex and a couple of tears in the grill cloth. I got a 1960a for $150 because 2 of the speakers were DOA and the "Marshall" logo was missing. In practice, when you overkill the cabinet's capacity like I do with a full stack (640 watts of speaker capacity with a 50 watt amp) speaker distortion is nill, but where does the cutoff lie on a 50 watt amp? 80 watts? 120 watts? As you say, the speaker model is a variable for this level's value, as well as its rating. Marshall has never advised this as far as I'm aware. But is this knowledge actually incorporated into designs or is this all just wishful thinking by me? We all advise people to use at least 1/2 again the amp power when buying a cabinet just to be safe. One ASSUMES Marshall knows how much power any given Celestion model can actually handle so a 100 watt cabinet can handle a 100 watt amp without blowing up. Speakers are (also) rated to handle the RMS wattage of their rating, so it comes down to how much more power does a 50 watt amp develop than 50 watts, and how much more power can a 50 watt (yeah I know, say two 25 watt speakers then) rated speaker handle. In theory this is reasonable, especially when you take into account that some Celestions distort more than others based on design, as you pointed out earlier. More often than not the wattage of the speakers is more than twice the RMS of the head so I don't get much breakup. So, you will want to figure out what style of music you want to use, HOW YOU REALISTICALLY INTEND TO PLAY THE AMP (bedroom volume 85% negates much of this), your preference on speaker breakup, and cab construction.įWIW, I have 1 50w 4 100w among other Marshalls and all my cabs are 412s. The 100w pushes them into the red zone (because 175wRMS of a 100w tube amp > 100W or 120W of greenbacks), and the 50w pushes them nicely (because 100w RMS of a 50w is right in that safe-max groove zone of 100-120w). If I had 2 plexis (100w and 50w) and I had a single 412 of greenbacks, I am getting speaker distortion regardless. HOWEVER Gibson67 is also right based on the speakers chosen. Ken is right that a 50w pushing a 412 will not be doing the work of its 100w counterpart, and downgrading it to a 212 of the same speakers will give the same results as the 100w through the 412 (minus the dynamics in construction of the two cabs). ![]() Three factors multiplied by X Amplifier heads and further multiplied by Y musical genre choices = no clear answer (just some possible suggestions). OTOH, there are the masters of high-gain lead, like Randy Rhoads and Zakk Wylde & EVH who have shifted focus away from breakup, instead opting for "clear" high-wattage speakers and letting their amp and dirt do the voicing. Throwing a plexi's 175w RMS at 8 25w greenbacks (175 pushing 200w max) has been a classic rock standard, and that breakup has been desirable for many musicians. One or two choices might be "better" than others for a certain application or "jack of all trades", whereas one "unconventional" choice may bring something new to the the table, or something bad.įinally, there is the concept of speaker breakup which in "this layman's" terms would be the speaker getting pushed by the power of the hard-working amp (a pure wattage issue). The individual voicing of speakers with the EQ focus plays a prominent role as to how the rig's tone is shaped. These factors promote "punchiness", or "openness", air movement, and bass response. You have construction/design, which includes size, thickness, whether open or closed back, etc. There are three dynamics (at least that I am aware of, maybe more) concerning speaker cabs.
