Hi, I have a TC Electronics RH450 amp that I play through a TC Electronics RS115 cabinet. I bought the RS115 used and at low volume it sounds fine. At gig volumes (50-70%) it sounds terrible. Boomy and too bassy almost to the point of distortion. When I turn the bass down it sounds better but still not where it should be. When I play the amp through a TC Electronics RS210 it sounds fine but not much low end which I need at times and is the reason I got the RS 115. I’m thinking there’s something wrong with the driver. I contacted the folks at musictribe and they told me the parts list shows the driver as an eminence delta15a. I’d like to replace it with a NEO 15” speaker like a Deltalite II, Kappalite or GK Neo driver to cut down a bit on the weight. I know I need to match the speaker specs with the cabinet size. Any thoughts or advice?
 
I usually use either one or the other, 210 in small clubs or where space is at a premium and the 115 if it’s a large venue or outside. They’re just too heavy and bulky to use together and most of my gigs don’t require that much volume even though when summer comes, who knows. I don’t think I’ve ever run them together. Are you thinking I should test it to see how it sounds?

Yes. I’m assuming they are both 8 ohms and you can chain them together in parallel. If you play loud, does everything sound good? Do you like it? At least you know your amp is probably OK and then you can use the information to help guide your next steps. When playing the 115 loudly, if you can EQ down the very low bass and play low-mid loudly, you may have a useful sound that doesn’t cause as much distortion. Many don’t like the lowest lows because they sound muddy anyway.
