I like most guitarists spend an incredible amount of time fussing over and evaluating music equipment and every little piece of gear that ends up in the signal chain. Achieving the ultimate tone is for the most part unachievable and is very comparative to finding the Holy Grail, photographing the Loch Ness Monster or spotting Sasquatch in the Pacific Northwest. There are however some gear purchases including amps, pickups, stomp boxes, cables, etc. that do make a vast improvement in tone. The EVM12L is perhaps the best purchase that I have made thus far in improving and achieving that elusive and ultimate tone.For one thing this speaker is rated at 200 watts and can handle just about any load a power amp can throw at it. It is a very beefy, well made speaker that is heavier than most drivers and could probably survive an atomic blast. One 8 ohm speaker was all that I needed for the Thiele cabinet enclosure that I put it in. The best attribute to this speaker is that it is very clean and renders no coloring or shading of your tone. This speaker is designed to accurately deliver what signal that your guitar and amp are offering up. I was totally amazed at this principle when I fired up the cabinet with my Fuchs TDS amp and the tiny little Thiele cabinet. Being a Jazz-Blues-Fusion style player, I was totally blown away of how crystal clear and articulate this speaker was right out of the box. I have tried just about every Celestion, Jensen, Tone Tubby, Eminence, etc. speaker on the market in just about every open and closed cabinet enclosure known to humankind. Finally, my quest happily ended when I bought the EVM12L!There is a reason that many players like Larry Carlton, Stevie Ray Vaughan and a host of other guitarists used this speaker. The player no longer has to worry about finding that perfect speaker-amp-cabinet combination. There is no breakup characteristics or tone altering elements to contend with which ultimately make my rig simpler to play and configure. I can now rely on my guitar and amp to do the job that they were intended to do. For the first time I can really hear the difference between my Fenders and Gibsons and consequently spend less time "dialing" in their tone. All that I can say is that this really works for me. I now have a whole arsenal of cabinets and speakers for sale because this one speaker does it all.
