Do speaker wires matter


I recently was given a pair of Mirage M1 speakers. All highs, mids and lows work but I don’t believe they sound like they should.

The tweeters are not giving the detailed highs. I am not sure if the mids and lows are where they should be.

i am currently using a vintage 2226b Marantz I just had restored. Impedance is 8 ohms and it only puts out 26 wpc. I know these speakers require A much more powerful amp. I’ve done a little research on this.

im wondering if the speakers could not sound as good because of the Marantz and/or also because of the speaker wires I’m currently using. I don’t know what gauge they are. They were given to me as well. Any advice would be greatly appreciated.

i did also find a Mirage technician in Canada who still repairs them if I’ll have to take that route. No turning back now 😊

Thanks so much for the feedback! So it’s sounding like if I were to get my hands on the proper amp and speaker wires to go with these speakers, they would sound infinitely better?  If so I would like to consider it. As I had mentioned before, there is sound coming out of the highs, mids and lows - just not too great. It’s sounding like I still wouldn’t at least hear the quality of these speakers at a very low volume with this amp because of how little the power it has to deliver. Just confirming that before opening up the speakers, taking out the tweeters and sending them off to be sweetened or rebuilt.

i am very new in this world so please excuse my ignorance.

I appreciate all of your insight and knowledge. 

Ive never taking a risk like this in picking up speakers like these, or any for that matter. A friend suggested I do it. He knew the previous owner who is sadly no longer with us and they wanted someone to take them. I went for it and am hoping they don’t need to be repaired, but if so I will probably look into it.
Start with a more powerful amp first and use the wires you have.  Later on, if you are enjoying what you hear, only then would I look into speaker cables.  
I also wanted to mention that I do own a Crown Base model PB-2 I used for my sound system for live music. It’s maximum output is 400 wpc into 4 ohms at 1khz with no more than 0.1% THD. (I have no idea what most of this means)

Would using the Marantz as a preamp and going into this be an option or would you advise against it?
