Are there visuals on the process for swapping the drivers? Guessing you just remove some bolts for the existing driver, carefully remove it from the cabinet, unplug the wires (assuming its a plug and not soldered), then reverse the process for installing the new driver? Guessing the drivers are fairly heavy with all of those magnets.

@abd1   My apologies for the late response. My wife got called back to work early which changed our vacation and plans.

A few thoughts...

1. it's not the speakers, which is important to state.

2. If you haven't already done so, I recommend getting a friend to help you with moving the speakers around so you can evaluate from the listening position as the changes are made. An audiophile friend will allow for two sets of ears on the changes / improvements heard from speaker movement.

3. For clarification, the toe-in with the cross over intersecting in front of me was for illustration purposes to make another point. My standard setup has the speakers intersecting behind my head.

4. Though our individual speaker and listening positions may be helpful, given YOUR room, I would only use them as a rough guide.

5. You may have already done so, but if it were me...given your room...I'd start with extreme near field positions for the speakers and you to eliminate first reflections. THEN, I'd move the speakers wider and your listening position further back by small increments UNTIL the point that the first reflections come into play (rear their head). THEN pull that position back in (slightly). IF you can live with that arrangement, you should be set. 

6. IF NOT, look into room treatment as others have mentioned. See if you can get a dealer loan for Stillpoint Aperture II panels with stands. They are pricey, but effective. They allow for easy movement (to test effectiveness) and temporary placement...which may be an advantage in your particular room and for your aesthetic needs. At a minimum they will inform you of the degree your room is involved and give you a starting point to address.

As is usual, I'm multi-tasking at this time of day....I'll follow up with more should I think of additional points.

Want to recognize @mikeg  @cal3713  and @alexberger  for helping out @abd1  with his room and speaker placement situation. I found their posts helpful and I learned from them as well. Thanks!

@vinpic  Thanks so much for sharing your impressions and comparative findings, as an owner, of the V2 and V1 versions of the Nenuphar drivers. It's wonderful getting owner feedback and I hope more owners making the swap post their findings, like you did.

Can't beat... : )

with V2 I am just happier

I'm assuming you have the 10 inch drivers. Is that correct?

 

 

Agreed, thanks for the help. I moved the speakers further back and apart and its sounding very good. Still toed in, almost crossing at MLP. Have to go out of town for work Monday so I'll continue to make adjustments when I get back. Still also looking in to some panels to help with reflection points.
