Advice on repairing / replacing the 15" driver in SWR Basic Black

Hello,

Today I found out there is an issue with the driver in my Basic Black. It makes a distortion noise when i play my bass softly through it. The noise either goes away or is drowned out when I play louder, and then it actually sounds pretty good. So I don't think the speaker is blown.

I'd taken the amp into Vacuum Tube Supplies here in Denver, they gave the amplifier section a clean bill of health but couldn't figure out the exact cause of the noise. They swapped in a different driver and the sound was clean, so whatever is wrong, its the driver.

I am assuming that I will have to replace the driver and would love some advice on good replacements / upgrades and places to buy them. However, while searching before posting it seems that replacing may not be as straightforward as just dropping in a new driver and there are other options for repairing that I wasn't aware of.

So if you all think that repairing is the way to go, I'd love any Denver recommendations of people with the skills.

I am the original owner of this amp and love it! I would like to get it back to tip top shape!


Thanks for your time,


Gerry

 

Thank you! I'll start with speaker repair companies and will share my experience here for future reference

 

thanks, although since they put a different driver in to test and the problem went away wouldn't that eliminate the amp? the tech also had the amp hooked up to tone generators and oscilloscopes and stuff and said that the amp part looked good

 

Thanks! Thats the thing, I originally thought that replacing the speaker would be a drop in, and considering that this is the first repair i've ever had to do i'm totally happy to spend $150 on a new driver or even an upgrade. Since I don't know much about this stuff I would have to rely on you fine folks for the recommendations though.

The thing is that as I was searching it seems like there is a lot more to getting the right speaker. I don't know what TS parameters are, but stuff like that If I go the replacement route I will need your advice on how to pick out a suitable replacement.

I'll give National a ring, but certainly if you fine folks can help me pick out a great replacement or upgrade driver I'd love to just order it and drop it in myself!


thanks,

Thank you! I didn't read up on this thread before heading down to National Speaker to see about repairing the driver. They took one look at it and said don't bother fixing the speaker and sold me an Eminence Delta 15A, returnable until its installed.

So it looks like its replacement rather than repair. Does the Basic Black manual:
http://support.swramps.com/manuals/pdfs/basicblackom.pdf

provide enough information for a driver recommendation or shall I do the measurements? For example there is a port on the back that I don't believe is mentioned in the manual. That C2515 looks pretty good to me, but of course I don't know what I'm talking about


thanks,
