I found this comparison to be enlightening and well worth my time. Even though I know parts quality can have a performance difference in many things, bicycles, wheels, kayaks, paddles, etc. This was the first time I was able to listen to speakers where the only difference was quality of the crossover parts. Now my opinion is informed by my own experience and I don't have to rely on other people's opinions.

Give it a try.

I'd be right pleased to do so.

Hmm, well, I don't know if I qualify as a 'flat-earther', but I certainly have my doubts about whether unmeasured/ unmeasurable things can be audible, and therefore a difference-making factor in audio gear. Is there a third camp between the true believers and flat earthers... say, the unwashed agnostics?

I tend to throw that term around loosely and some take it as a poke in the eye. But the guys that really fit the term are the guys that let preconceived beliefs get in the way of learning or listening.

And it is okay to have doubts. It is okay to be skeptic. Just don't let that get in the way of listening. Keep an open mind.

My gut feeling is these might have some potential, but they come with some challenges...



They are quite small so the bass is limited to 120 Hz or so. That was easy to take care of.



Even though they are spec'd up to 20 KHz, they could really benefit from the addition of a tweeter;
however that would involve a crossover, and there's not a lot of room for either one of those things.
 


Each speakers contains two 2" BMR drivers. If I am not mistaken, the lower one I believe
operates between 120 ~ 150 Hz while the upper driver handles everything above 150 Hz. 

Might not be very practical or cost effective, but who knows?   Thoughts??

No project is too big.

Great picture!

You can always send them over to me and I can measure and test them to see what there is to work with.

Danny, I’ll try to get them boxed up and out the door next week. They will be coming from Canada, so I’ll have to look into the bureaucratic procedure of doing this the right way so neither of us gets dinged for customs or tax upon delivery.

This address... 910 N. Jackson, Iowa Park, Texas 76367 USA ...is up to date?

I can still receive shipments at that location.

[Wind Chaser]

According to your website’s contact info, that’s your address.

If however you have a more upto date address, I would prefer to use that.

[Danny Richie]

That one is still fine for receiving. I am still working out of that office for a little while longer. I have a much larger office and shop that I am still moving into, but I am just not all moved in yet.

Danny, I've got some Rega Kytes on the way that seem to benefit from some mass damping of the enclosure. They're loosely filled already, if I install No-Rez on the sides, should I just leave the wool as-is?

Thanks

It depends on the size of the speaker. Most of the time you can place the factory damping back in after lining it with No Rez for best results.

Regular banana's will fit into the the receptacle on speaker with your binding posts right? I'd ruin my speaker cables should I cut off the factory banana, (ruin for resale that is.) I have rather pricey cables that is.

[synergy1]

does the speaker cabinet build need to be sized Bigger to accommodate  No Rez? If the factory insulation is put back on top the inner volume would appear by eye to reduced by the 1" no Rez and 1.5 inches of insulation. how's that work?

Banana's fit fit right into the tube connectors, but it will not sound as good.

I don't think swapping out the ends of your cables will alter the resale value. Ends can be swapped on and off without issue. And you are upgrading the cables to work best with tube connectors. So some might consider that to be worth more.

No, the No Rez will not alter the volume of the cabinet. While the barrier layer does take up air space, the foam layer slows down the flow of air in the box making it act as a lager box. So the end effect is close to a wash.

And you can still add back in some of the original insulation to further tune or tweak how it sounds.

I am curious as to whether you managed to improved the CA Minx mentioned above?  And to what effect on the sound?

It would be really hard to say as to what could really be done with them. There is not much there to work with. And for not much money we already offer a really high quality small speaker design like that.

I can attest to the quality of these little speakers. In addition to having a pair of them myself, I have shown them at the Lone Star Audio Fest for three years. Everyone who heard them were blown away by their performance.

Yes, standard banana plugs are the same size.



But you do loose quality passing the signal through the tip of the banana plug.

The male stud for the tube connectors is completely hollow. So your speaker wire slides all the way through to the end of it. This is three 16 gauge wires spiral wound. I think it equals almost 11 gauge.



Then just crimp the end, solder it and heat shrink it to seal it.



If you use the banana plug it puts your speaker cable a long way from the internal wire. And it puts a lot of material in the signal path that is not an ideal carrier for the signal.



There is clearly a difference in clarity if you use the male studs.

What is the contact resistance of this versus a normal binding post and banana plug connection?
