Default Can you equalise too much

Hi guys
I built my first speaker last year. unfortunately despite being well constructed the cabinet was totally out of alignment for the driver. I didn't really understand that a cabinet designed for a an Alpair 6.1 wasn't suitable for an Alpair 6p.
I have made many changes to cables, dacs, amps ect but of course to no avail.
I finally got a minidsp and added a sealed sdx7 for a sub, with very heavy equalisation it sounds OK.
I chose the wrong drivers and the wrong cabinets.The minidsp can do a great deal but is this level of equalisation desirable ?
I can't help thinking a fresh start is needed.

A little EQ with gentle slopes and not too much is ok. How much EQ are you applying (gain and Q)? Avoid EQ'ing in 500Hz to 5 kHz range unless it is just gentle shelf for BSC. Avoid peak boost and apply cuts.

I've got my 6p's in prototype boxes that were originally for the 6M, and they don't sound bad at all. Can you link to the box design that you used?

Hi Jeff thank you for your reply.
Here is the link
Small MLTL for Mark Audio Alpair 6 Drivers

I think that I would have been better of with the 6m. My 6p are very treble happy and have a sharp peak around 3khz. I understand that many people are happy with them and am not saying they are a bad driver but probably the wrong choice for me.

how much different is your 6.1 cabinet from what's recommended for a 6p?
re:eq - if it sounds worse overall then probably not effective

Never heard this before, but my drivers are in Planet_10 Mar-Ken boxes. I've always thought they sounded quite smooth, with no obvious dips or peaks. No experience with them in an MLTL like Jim's.
