Sda 2.3 driver??

Phasewolf

I want too know if anyone took the mw6511 and switched them too where the mw6510's are and then just put the right speaker where the left would sit so they were like the 2.3tl's. I am thinking about trying that out and removing the 6513's and placing 11's in there place.

Any thoughts on this idea?

quadzilla

Probably not a good idea, since the 2.3 and 2.3 TL have completely different crossovers. Also, the 2.3 TL only uses the MW6510.

Phasewolf

Yes I have looked at both. I would not be rewiring them just changing the driver position and maybe swapping in the 6511's for the 13's. The 6511 and the 6513 are both 4 ohms and the print called for the 11's13'srest and was crossed off and they used the 13's instead.

I have to agree with Quad on this one. While it kind of makes sense at first, those are two completely different xovers and were not designed to be changed like that. If you do try it, let us know what you think.

I would def. not switch the position of the speakers. They are designed to sit that way.

As for changing the 6513's for the 6511's I did it and like the way it sounds. Best part is that it isn't final and can be changed back if you like. The bass was more pronounced and has a better and wider soundstage.

Just keep the cabinets the way they're suppose to.

Good luck

Phasewolf

Thanks for the info on this one. The next thing I am going too order is new inductors too replace the old 16.8mh one that are in there.

I don't want to call BS on this one but...BS, At risk of being the anti cable thread...I would lay a dollar ot a dozen donuts that says no matter what 65XX driver you use in whatever position you use it in you won't be able to blind identify the difference.


Aside from that...I wouldn't go switching the speaker position either. I first read it to say a simple "Swap drivers for a different in its series" Not change cabinet position. I wouldn't suggest swapping the cabinet position at all.

Phasewolf

I was thinking about doing one or both. I own a copy of real rta so I can record and see what changes happen or for that matter don't.

SDA1C

Id be very interested in your results. I know there are subtle manufacturing differences but the actual audible or measurable differences are a whole different story.

I do know the time alignment would be off if you swap cabinet position without swapping xovers but the whole "drivers are way different" thing doesn't do much for me.

Now if you said swap a Polk for a B/W or a Dayton then I'm sure there would be an audible difference but between the any 65xx and another...not so much.

Phasewolf

Well the donut drivers are weighted and the 6511 are not so there sonics would for sure be different his I am not sure and that is part of what got me thinking. The speaker position should not be dependent on the crossover that much sense the speakers will be getting the same signal I would not change how it is hooked up.

SDA1C

LOL. I wasnt referring to the donut drivers.

I was referring to the swapped position of the dimensional drivers as wired from the xover. I was meaning the dimensional drivers need to stay on the outside or your stereo signal will overpower them and cancel some of the sda effect.

Phasewolf

Oh yes I understand that. I was going ti do the swap and then place the left cap where the right should be and the right where the left should go that way they are still on the outside.

SDA1C

That would be my only concern. The rest I don't think would make much of a difference. The whole overall project will net drastic changes but a driver series change here or there wont do much I wouldn't think.

Phasewolf

I think one of my friends has some 6511'shelp that I can barrow and test things out well see I guess.

I am guessing for something fun to try. I am curious. It will definitely be an acquired taste sort of outcome but I 'd like to hear the results.

Somewhere in here is a spec list of the different MWxxxx drivers. The differences can be significant.

Toolfan66

The 2.3's are a fantastic speaker if your feeling the need in doing this because you feel they are lacking something then maybe you should look at the gear your using. In my experience these speakers do not lack anything. If your just looking for something to do then take your girlfriend or wife out to dinner and forget about it..

Often heard about this list. Would sure like to get my eyes on one. I have inquired a few times if anyone has one.

You think you can dig this up Jesse ??????

SDA1C

This was available a while back but I have yet to find the list that references what model # takes place of or corresponds to which discontinued driver.

I do see differences (some not so subtle) and I would imagine if you replace with the farthest ends of the spectrum in some of the larger SDA with a cumulative effect it would certainly be noticeable.

It's not that I am really trying too make them better in some way or a other I am simply playing which is why I am doing things that I can undo with no harm too them. Plus if I cant barrow the drivers I am not going too try as I don't have the money too just toss away. I really want too just hear for myself why they went with the 13's over the 11's sense they were what they listed and then crossed off.

Because Polk felt there was too much mid-range.

Phasewolf

With the way the 13's are made would they not be made too produce more bass ans less midrange?

Joe08867

No, The donut slows down the movement which will help them produce more mids.

Also the other swap you were talking about could be bad also. The 6510 and 6511 are very different speakers one is 3ohm the other is 6ohm. You could actually harm your amp or receiver with the wonky ohms.

Phasewolf

OK I thought I read that the more weight the driver had too move the lower the frequently it would be tuned too. As for the moving drivers I was not not going too move the wires just they drivers location.

That is incorrect. The weight slows the driver down so that it doesn't produce mid-range. Also, if you look at the schematic, you'll see that they are wired completely different than other SDA's.

Phasewolf

Yes F1 I can see that they are as I said it was just things I was playing with in my head. As of now I am going to order some erseaudio super q inductors. Can't wait.

And now that I thought about it you are right. I had a brain **** or something earlier.

Which ones are you ordering?

Phasewolf

I think I am going too go with the 15mh 14 gauge or maybe I will just order the 18mh 16 gauge ones and unwind it some but I like the lower dcr of the 15mh coil more and I have seen others use that one and they liked it.
