Over my many years of thumpin' on the bass, I've played through bunches of amps - both combos and seperates. It never fails my ears that, no matter what cab I'm using - one or multiple speakers - always sounds bigger and fuller when another cab is added - again, no matter the number of speakers in either cab. I know that generally, more power is generated, but I'm not talking about volume or loudness, just the bigger fuller sound. I've just completed semi-restoring a late 70s early 80s Dean Markley 1-15 bass cab with an Eminence alnico unknown wattage (probably 100) speaker. After doing some repairs, replacements and joint reglueing, I was putting it through the paces and it sounded actually better than I thought it would. I'm also working on a complete resto on an Accoustic 301 cab (1-18 CV 300 watt speaker) and so it's standing there near where I'm playing and I decide to hook it up too. Once again, I was amazed at the fuller bigger sound the 2 of them together made verses one or the other individually. Just one more instance of this phenom occuring. Any other of you TBers experience this? I'm sure there are explanations, but it's just IMO odd that, for example, you take a 1-15 cab and add another 1-15 cab, and you get the fuller bigger sound than with 1 cab with 2-15s, with everything else being equal.
