    First impression, these speakers are awesome! I’ve compared them to the bowers and Wilkins 702 S2 and the audio quality on the X-MTM is far superior. I’ve never built a speaker before and I had no issues whatsoever, also Danny and his staff are very responsive and helpful. I would highly recommend these speakers!

    My first build ever. GR-research was exceptionally helpful throughout the process answering questions and offering advice. With the X-MTM Encore design, Danny and GR have done their homework. X MTMs are very balanced, have a flat response and excellent off-axis response. Very pleasing to be able to move about and still enjoy excellent reproduction. I sold my Klipsh RF-82s immediately after completing them.

    The level of detail is truly amazing and accurate timing brings clarity to all instruments & vocals. Does female and male vocals equally well. You will be impressed. A very polite speaker, never harsh. Zero fatigue, even after hours of listening. Drawbacks are slight: The very low bass with the 6 1/2 woofers could be supplemented with a sub. Not felt like a pair of JBL or Klipsh.

    They will reach down to around 40 hZ depending on room size and placement, but I wish they had a little more for rock/blues. The bass is not muddled or mishandled by no means but they are a little power hungry if you are used to 91-94 dB speakers. They do come alive around 40 watts but I would recommend at least 40 as a minimum. I am hoping that Danny will design an 8″ MTM design someday soon. The X-MTMs are a unbeatable value for what they deliver vs what they cost. I opted for the tube connectors and the base capacitors for this build and I used plywood for the build double up for 1 1/4″ thickness. I would recommend the flat pack if I was to do this again.

    Overall, at this price level, one of the best designs I’ve heard for balance and detail. You won’t hear something out of place or over emphasized with the X-MTMs. I don’t know how to convey the level of detail these can bring about but you will notice it immediately, even if you have listened to your favorite tracks hundreds of times.
