3-4 dB dip at crossover region: what should I listen for to hear it?

Today sound pressure meters are very inexpensive

get one with a tripod fitting

next a CD (not LP) with test tones, many single frequencies, and you set the mic at seated ear height at your listening position.

They don't have to be laboratory accurate, just give you relative differences, i.e. + ____ db or - _____ db than the prior frequency.

My test tone CD has 29 frequencies to compare. Expensive, you could find something else

You are measuring the space as well as your speakers. Slight relocation, slight toe-in adjustments differences can be found.

I just read the review and Amir from ASR actually put that speaker on his recommended list. Beyond measurements, he was pleased with the sound.

You don't want to hear it, because then you can't un-hear it and you'll be looking for new speakers.  If you like the sound, close all ASR webpages, and just listen to the music.

Believe it or not I actually would like to hear it, if only so I can better relate measurements to performance. The thing is, I’m not sure these speakers are right for me (too soon to tell - I always take a long time to adjust to new gear), so while I’ve got them I might as well learn from them. These are my first horn speakers so I bought them as much for the experience as anything else.
