I was listening to amp comparisons, and found that 4x10"s give recorded guitar massive quality - in one recording I thought I could hear the other speakers add this massive 3D-quality to the sound from the one with the mic in front of it. Help me out with the design? I think it should be closed back, no idea which speaker-elements. So, now I have a gas for 4xNN guitar speaker cab. I often have the weirdest gas... ermm yeah, one of these threads I guess I'm just susceptible to toys and marketing. Now I'm fighting the urge to buy russian tube amps (Yerasov, Novik...) and toys with lot of small metal boxes (Boss Katana, Two Fingers...). It's as if I was still 17! I decided I need to cut this guitar-combo-and-fad-effect-box-GASsing part of me out! ( before it hatches, grows into my brain and turns me into a sorry ass guitar product consumer - as opposed to practicing music as means of expression and art =) Soo, my logic is to get an inexpensive power amp, that I can use for guitar, bass, lyrics etc. I have a 12" bass cab, a 2x8" too. The 12" bass cab is excellent for guitar, but not for recording. Strangely, I find 4x10" cabs record great (because the 3 other speakers multiply the signal at the 1). I'm a good enough carpenter. I might be able to pull a cabinet build off, and solder the leads to connectors but my cab designer skills are minimal.
