Needing to replace thirty year old speakers.

I second @mark200mph - tekton moab would be amazing for your space/bass requirements.  Not sure how large your room is, but these can energize a fairly large space with their 4 12" woofers.

I have heard a lot of good things about the Goldenear stuff as well but haven't heard them myself.  If you're looking to get rid of subs, go tekton or goldenear.  The rest of this stuff is not going to give you the sub frequencies you want, hands down.  The mofi 888 has two 8" drivers for bass... if you really think that's going to give you sub bass, you may want to read about physics in regards to driver size/piston area.  I have heard the 888, and although I enjoyed their warm and full sound, they just don't touch my double impacts or my friends Moabs.  If you're able to go by tekton, or call Eric, I'm pretty sure you'll be pleasantly surprised.  Return policy is generous as well.

OP,

contact TMR and plan ahead, it's possible not everything is at that location or ready to play. I don't know how they work.

I'd want to hear those ones made in Cody also.

Tmr does not let you listen to speakers in general.i have been there several times.

I have the golden ear top of the line and even thier old definitive technology sc 7000 prior to the selling the company and starting goldenear. I still prefer the moab tekton . ITs a great value for the money. Enjoy the hunt. I have several reference level speakers and the tektons sit next to them and sould right there.

IF you go to TMR in Erie, near Denver, there seem to be quite a few dealers in the area

Near Denver, any good dealers there?

Listen Up has several stores in Colorado
