Oh, low end it is your looking for. Sorry, somehow I missed that part. In that case the last examples went in a totally wrong direction. But more low end is very much possible. Here's another attempt:
lol, I do like the amount of low in my example, but I'm not after that in this case. I'm after getting all my VSL instruments to sound as good (and relatively with a degree of consistently) when processed through reverb.

I felt like yours had a bit too much boomy low so I cut it down a bit. Now I feel like it's closer to mine. However, notice how the low end sounds fine but the verb isn't giving us as much high end. I imagine it's possible that could have to do with the IR you put it in. But mine still sounds more natural to me because I'm hearing the lows and highs represented equally as it sounded from the instrument itself. That sound continued into the hall. The dry examples seem to suggest the dry instruments aren't accurately represented when processed through/against an IR.
I'll try to add a better example later today now that I have an MIR demo to test it. But I think it's pretty apparent in comparing my tweaked version of yours to my Brass #4. Thanks for the examples. It's at least very helpful in comparing. 😊
