Don't worry, I'm not one of those bass players.
Don't look at me, I just do what greenboy tells me.
Because I've seen driver testing for MANY speakers (I'm sure you have as well) over the past few years, and I know that some drivers are just not worth the cost. Not to say that the 18 Sound isn't worth the cost......THE BEST pro audio midrange test I've ever seen was an 18 Sound mid so I know they've done their homework. I just know that it's possible to build an amazing mid for way less than $130, so someone has had to have done it. We just have to find that needle in the hay stack.
I wouldn't be shocked if the Alpha6a does something WAY better than the 6ND410 because it's so much less efficient. It's a trade off. No driver can do everything perfect. The guys at Eminence aren't idiots. If they wanted the Alpha6a to hit 110dB's at 1 watt, they could have done it, but the driver would have to seriously suffer in another area of performance. Driver design is a balancing act.
And I know I'm not telling you anything you don't already know.
Thanks for all of your work and time that you dedicated to this thread.
Well I tend to ignore price as an indicator of quality, and I'm quite willing to pay less for something that does the job for me as well as something that costs more. But if it costs more and I think I need it, I'm willing to pay. So if I thought the $135 18 Sound driver was the ticket, I would get it.
Fortunately for me, I'd want one that cuts off the highs at between 4-5k, so I could probably save some jack. I suppose I could cross it over to a tweeter at any point I wanted, and if it really worked for this cab better than anything else out there I would get it, but I'd be happy to get the Alpha 6a if the 18 Sound was overkill for my needs. I have a feeling I'd settle on some middle ground, though.
I added a redirection page in the wiki, which will help for copying and pasting fEarful's URL :
The "tm" in the name is encoding dependent and is somewhat hard to use.
Also the variation in driver performance before and after break-in - although the T/S specs won't shift that much on a midrange I bet something changes in how the cone self-damps after it's been given some high power use.
I am really interested to hear about the real performance of the 6md38 Would be nice to save some cash.
Reminds me though, did someone find some reason why the 6PEV13 was unsuitable for midrange for bass? I can't recall if there was ever any discussion around that.
I've been wanting to pull the trigger on a SoundEasy rig for a couple years now but my recession induced, financial dilemma doesn't allow.
Unfortunately, John Krutke (ZaphAudio) no longer does driver testing for the DIY community since he began designing his own drivers.
I didn't realize that Brandon (DriverVault) had done testing on the 6ND410. It would be nice to get some 6MD38 test data from him to have a comparison under the same testing conditions. While we were at it, we could send him a 3015LF as well. It would be nice to see the numbers on this driver.
Eminence might not, but it seems that B&C does. If the 6MD38 is suitable (it appears to be), it would be nice to have this option for the 15/6. The savings by going this route would be in the ballpark of $80.
That's not all that bad. I'm waiting to build it when he's finished.
I agree...many of us aren't audio hobbyists, and this is our first exposure to some of the topics, issues and science involved. Its been a great learning experience and has given me some interest and hope to do more in the future. Unfortunately most bass players are 'end users'.
Care to give any details on the hows and whys? I didn't notice until I got home and had a moment or to to scan the plans that the plans integrate the crossover (high-pass/low-pass) and L-pad in the same circuit.
Of course, the next thing I noticed with my limited understanding was the differences in component values which produce similar (but not the same values) as those of the basic 3.5db pad that I used...
See my comment above...it only just sifted through my thick head that you don't need to order build a pad to use this crossover. Shipping for Parts Connexion is fairly dear. I paid $27.25 for my 5 resistors, and then paid $15.00 shipping for regular US mail, which looked to be the cheapest they offered. Now, part of the problem is they don't assess the shipping when you place the order, but only after they've invoiced.
If the 6ND410 is what it takes to make this cab sound great, I have no problem paying for it. It's just that I ordered 2 of them. But I'll be happy when I can get the wood. I like to get the parts before I make the cab. Can't Waite to get started. If every thing works out. I'll sell my ElWhappo and Schroeder 310212 to cover expense's.
Passinwind, is it necessary to use a tweeter with the 6MD38? The 6ND410 does have a rise in response that starts around 2000Hz, with a big peak centered around 4400Hz. Would the tweeter be used with the 6MD38 to give the impression of a similar "bright" top end? With further inspection of the response curves, I could see how the 6MD38 might appear to sound "dark" as compared to a 6ND410.

What's going on? All of greenboy's posts have disappeared from this thread.
He probably has something earth-shaking in the works. I hope nothing bad happened.
Yeah, but it's weird that all of his fEarful posts have disappeared.

no ban or even any points showing
Long shot. Any chance of this?
Hrm...I had been wondering about exactly that lately.
Wow! What's going on? I've been away for awhile and damn... Is this whole thing going to fall apart?
BTW. I finished the 1515/66 awhile ago and it's incredible!
