Options for resolving a slightly bright sounding speaker

I have built up a pair of speakers using 6.5" mid/bass drivers and 1" titanium dome tweeters. The efficiency of mid/bass drivers is 87db and the tweeters 92db. Both are nominal 4ohm impedance. I built the crossovers myself using an online calculator with the x-over at 2.5kHz, audio bipolar caps and hand winding the inductors on open air formers. I used first order for the hp and 2nd order for the lp.

The sound is very clear and open the bass is there but the overall sound is a little bright. I suspect the brightness originates from the higher efficiency of tweeters.

So I have a couple of options in mind

1. Split the lp/hp in the crossovers and bi-amp (I have an unused channel on my amp) . I can then control the gain to precisely tune the sound level between the drivers to my ears.
2. Attenuate the hp filter to match the lp with some more components on the crossovers (this gets very complicated very quickly).

Or just accept as is and adjust the treble.

Any help or advice would be appreciated :)
 
A 4 ohm 3kHz crossover for your drivers in about 15L looks like below.

You'll always need some 7-10W wirewound resistors for correct treble level. And adjust the red one to taste.

How close to that are you?

Hi,

After implementing some baffle step compensation, (which by
the sound of it you haven't). mid treble sensitivity is going to
be around 83dB. The tweeter needs two resistors in an L-pad
to drop its sensitivity down to to the same as the midrange.
