Has anybody done an A-B comparison of the EPS 15 and the TT 15? What's the difference in sound/tone?
I know tone is very subjective, but would like to hear your take on how these two compare. |

| Also, both of these speakers compared to a JBL-D130 |

I did field testing on the EPS-15C for Eminence. I equate the EPS-15C sound to a JBL K-130 (My impression the first time I tried the EPS-15C, "This sounds like the JBL K-130 I had in a Fender Twin amp").
I replaced the stock Quilter custom voiced Eminence EPS-15C in my Quilter Steelaire with an EPS-15C.
Here are the response curve charts from Eminence for both.

I have alternatively put both speakers in one of my amps. Both speakers are great, and I have to say that from the outset. The key areas for me are the high frequencies and the mid range. After A-B'ing the two speakers, I came to the conclusion that the EPS 15 has significantly more high frequencies in there but that the Double T has a more detailed mid range, especially the upper mids.
Most Neo speakers to my ears have excessive top end. Of course that issue can be controlled somewhat from the eq on the amp, but any substantively significant movement of a dial will (in my experience) have a knock on effect on the whole overall sound. The Double T required more of a convention eq setting.
I have kept the Travis Toy TT 15" in my amp, and I have been very pleased with its performance. Thanks Eminence and Travis Toy. The EPS 15C now resides in my Webb amp where I have utilised Tommy White's suggested settings for a Webb with a JBL speaker in it.

Thanks Ken. The frequency response graphs don’t really paint the whole picture (especially since the dB range scales are different on them) on the fairly significant tonal difference in these two speakers. A definite goal of mine was to design the NEO “eek factor” out of my TT speakers. It was not an easy task. NEOs are so much more efficient than traditional magnet designs, that they really want to, and have an easy time reproducing high end frequencies. I’ve seen some of the NEOs still going strong up around 5kHz. The reality is, for a steel speaker to not sound too zingy on the high end, you really want the response to be sloping off pretty quickly after 2 or 2.5kHz. The problem with trying to control that response with an EQ knob is, if that frequency response is inherent in the design, the speaker is WANTING to try and replicate it. You can try to tell it not to with a knob, but you’ll be in for a fight. If you can tame that response in the actual design, it’s gonna be way easier to control it with your EQ section.
My two cents. Haha. Cheers!

There we have it - straight from the horse's mouth. Travis, thank you for that concise and more technical explanation of what I was trying to allude to. Quite simply and somewhat clumsily, I was trying to say that Travis's Double T speaker in terms of reproducing steel guitar frequencies is way smoother and warmer.

My new TT-15 arrived today. It sounds fantastic right out of the box!
Congrats to Travis Toy and Eminence. |

Tommy, thanks for placing trust in me and trying the speaker. I don’t take it lightly, and I never put my name on anything that I don’t 100% believe in. Glad you love it!
