Great choice for fine-tuning your tone! The speaker with a built in tone knob!

Comments about Eminence Maverick FDM Tone Adjustable 12" Guitar Speaker - 8 ohm:

The Eminence Maverick 12" 8 ohm speaker serves as a replacement for the original 1964 CTS ceramic that has been living in my 1966 Ampeg Gemini I for over 45 years. I decided to preserve the original and began a tedious search for a replacement. Finally, after months of testing, I settled on this new design from Eminence. The Maverick is an amazingly clear, crisp, detailed speaker. It remains articulate at high volumes and has a tight, focused low end response. The Maverick never becomes woofy but really has a lot of low end capability. Whatever is coming from your amp, the Mave can handle it beautifully. The midrange is slightly scooped in the 1-3KHz range which manifests itself as accentuated lows and highs. However, it is not a dramatic "modern" high-gain style scoop. The speaker still has bite in the midrange and retains a vocal quality most noticeable while wailing single notes in an overdriven format. The highs on this speaker are where it really excels. Never glassy or brittle. There are no piercing spikes. The high end is very smooth and round and works deliciously with hot humbuckers. The combo of the '66 Ampeg Gemini I / Maverick / Seymour Duncan "Jazz" SH-2n produces what is by far my favorite guitar tone ever. It's like a violin/saxophone/woodwind tone. Amazingly smooth and buttery. In a lot of ways, it is the perfect speaker. The beauty of this design is the FDM knob on the back. It effortlessly turns 300* to give you it's full gorgeous bell-like chime, yet if you decrease the efficiency by turning the knob to raise the magnet it becomes a darker image of itself. Incredible. If you have an amp that just needs a tad more tone tweaking towards bright/dark this is a great choice. The Maverick offers -9 decibels of volume attenuation. That is really not that much of a decrease overall. If you are looking at this to dramatically lower your bedroom volume while driving the power amp hard, look elsewhere. Perhaps you need an attenuator like the THD HotPlate. What it can do is trim those treble and mid spikes that your amp can produce as it gets louder. The FDM function is more of a "tone knob" than it is a "volume knob" though there is a decent volume decrease overall. This would be an amazing match in a 212 with a V30, Blue Alnico, or even the Reignmaker imo. Tons of tonal possibilities here. Once it breaks in, it just gets smoother. Great buy! You gotta hear it!

Close, but no cigar

Comments about Eminence Maverick FDM Tone Adjustable 12" Guitar Speaker - 8 ohm:

NOTE: I rated this product 3 stars because I didn't think it is quite worth 4. If the choice were available I would have given it 3.5 stars. I recently bought a used late 90's Carvin Vintage 33 tube amp. Love the sound, but the amp is so loud that I couldn't turn it up past 1.5. I bought the Maverick in hopes of gaining more control. First, even with the speaker cranked full on, the amp is slightly quieter than with the original Carvin speaker. The resulting attenuation when turning the speaker down was less dramatic than I'd hoped for, but it lets me turn the amp up to about 3 or 4 without going deaf in my large home practice room. Second, compared to the Carvin speaker, the sound of the amp with the Maverick has a little less high end sparkle and is slightly compressed (less punchy) than before. The amp still sounds much better than a stock Fender Blues Jr (my other choice when looking for an amp), but has lost some of the character that put it head and shoulders above anything else that I could get without paying 2.5X as much. I honestly don't know if my disappointment is due to the Maverick being a poor speaker or just that the Carvin is something really special & any change was bound to hurt the sound. Potential users will have to make their own judgement on that. As they say, "your results may vary." Bottom line, I will probably leave the Maverick in place for now while using the Carvin as a practice amp, but if I gig with it I will go back to the original Carvin speaker.

Better Than Expected

Comments about Eminence Maverick FDM Tone Adjustable 12" Guitar Speaker - 8 ohm:

Although on-line reviews were pretty limited, based on what I read and what I heard through on-line videos I decided to take a gamble on this speaker. I'm glad I did. I play a wide variety of covers using various six-strings through a mid-90's Mesa Boogie DC-5, which is a great amp, but sounds best when it's cranked up louder than it should be for the rooms I typically play. At lower volumes I always felt as though the speaker was a little stiff, and maybe a little strong in the lower mids. The amp's graphic EQ can adjust for almost anything, but I sometimes felt as though it was a compromise, and that I wasn't getting as good of a tone out of the amp as I could. These amps have a reputation of being hard to dial in, and I can agree with that in the context stated above. Anyway, I listened to both the Maverick and the Reignmaker on line, and decided that the Reignmaker had some of the same tonal qualities that I was trying to work around with the stock speaker, so I opted for the Maverick. I was expecting the attenuation to be the most useful feature of the speaker, and that I would end up running it dialed all the way down, or close to it. Color me pleasantly surprised. Even at very low volumes I am getting a great tone with the attenuation minimized (the speaker FDM dialed all the way to the loudest setting). I find that the Flux Density Modulation acts more as a tone control than a volume control (although it does attenuate volume, too), and I'm able to get a wide variety of amp characteristics by adjusting the dial.(By the way, unlike what some others have reported, I found the dial to turn rather easily throughout the entire range, except it sticks just a little at the most clockwise position, but no big deal at all.) At max attenuation it feels as though I'm playing through a looser, vintage-voiced amp with slightly reduced highs and a little more midrange push. At minimum attenuation the amp feels tight in the lows and crisp in the highs, with just the right upper mids to make the notes cut through. These features are apparent through both the clean and dirty amp channels at both lower and higher volume levels. When I finally gigged with my new set-up, I left the FDM knob at about the center position. This gave me some of the characteristics from each end of the FDM range, and I'd go so far to say that I got the best of both worlds - not a compromise at all! I used both the clean and dirty channels of the amp, along with a couple of different dirt pedals, wah and the typical chorus and delay through the loop. I was totally stoked with my tone that night, no matter what I stomped on. The Eminence Maverick turned my Boogie into the amp I always knew it could be. It's not going anywhere! And it's not even broken in yet! Highly recommended, folks.
