You also have to consider the total load presented to the amplifier. Four and eight ohms in parallel. equates to 2..67 ohms . If the SS amp can't drive that impedance the amp dies..
The actual position on the box of the port is not important. My rear ported Acme B2 2x10 three way cabinets work very well stacked as a vertical 4x10. it's my standard configuration.
Standard thing to try if the amp has an Effects Loop is to connect the Send and Return with a signal cable to bypass the normalizing contacts on these sockets. They are prone to oxidation especially if little used.
Any amp will sound it's best when put through a superior speaker system like an Acme.
Andy does make good stuff. I have four B2 models each at 4Ω.
Enjoy!
Back in the day before the thing ws stolen from the 21 Club in Liverpool, I owned a Gibson EB0F with a built in fuzz effect. It was awfull and completely unusable.
That is an over simplification. Tube amps give a pleasing distortion when pushed too far. If a cabinet is rated for 750W you need at least that much to make it 'sing'.
Meaning no disrespect, I don't see the point of buying a powerful speaker cabinet and then castrating it by driving it with a 50W amp. Even in the Sixties 50W didn't get you too far.
I seem to remember that the VR was not too well received in the pages of TalkBass. It does strike me as being a bit on the expensive side. That said I have little experience of pricing in the UK.
You know, we don't really have to follow any topic from TalkBass. We are more than capable of coming up with topics of our own. Besides which we can spell better on this site than they do on TalkBass!!!
LOL
@DaveBassMan2115 Try plugging a signal cable between the Send and Return of the Effects Loop to see it that helps. Corroded normalizing contacts on these jacks have caused a lot of problems in the past. If it solves the problem leave a short cable like between effects pedals in place.
Buy the four conductor Speakon as it appears to be a standard across cabinetry manufacturers. Wire the two conductors of the speaker cable to Plus1 and minus1. That's all there is to it.
