Dip in frequency response, fix ideas?
 
Hey guys.
I bought a bunch of HiWave BMRs for a line array and am debating on how to correct the dip around 1.5k. I want to use this full range but I can hear the dip. I was thinking of a few small mid drivers with a 4th or higher narrow band filter. I have already tried this and it actually works. But before I do this I should ask you guys what else can be done that I may not have though of already.

Thanks in advance! :)

Have you listened to them in an array all ready, or just a single driver.

Once you put them in an array, they are going to exhibit comb filtering with a downward FR. So they will need eq anyway.

I have done 8 drivers. I plan on using 12. I used a morel cam mid crossed 4th order from 1k to 2k and was able to adjust it's volume independently, it helped a lot.

Ideally I was thinking a button type driver that does 1.5k and put those beside or every other. I am using tweeters as well and augmenting bass with 8" woofers.

Have you measured the FR?

Are these the 2" BMR"s?
Nevermind, I just clicked on the link.

Not yet, just going by ear and referencing other speakers. My little mixer I used for phantom power for the measurement mic died on me so as soon as I pick up another I can measure.

They are amazing little speakers for $6

I can't picture this speaker.
You want to use these full range you say....but you are going to use tweeters.
And mids? What like alternate the hi waves with the mids to smooth out the dip?
