Yes, one cannot expect to get good results only by looking at spec sheets and applying theory. 
There are many circumstances that combine to produce the resultant response.

If you are not able to hear the difference between an EV DH3 and TAD 2001, I would say you are suffering from hearing loss. I find the EV to be very harsh and unpleasant.
Even if the electrical XO is 24dB LR at 8khz, this does not necessarily mean that the HF is down 24dB at 4Khz, acoustically. I measured -15dB on axis at 4khz in this configuration. So there is still alot of contribution even below 6khz. Looking at the equal loudness contour, our ears are still very sensitive in this range.
You are of course entitled to your opinion, but I struggle to see how an opinion can be formed without actual experience.

Not sure what you mean by gain structure in this context, as this is something that applies to the signal chain. The amplitude is of course level matched to meet the 6.5".

I have an absolutely mint Floodlight 760 if anyone might need a single one. Was sat in F1 factory for years and years literally is mint, original paint job, no chips or dents at all. I bought it meaning to buy two more but keep buying other rig so if anyone needs a third in perfect nick with all original un-gigged drivers let me know. Guy I bought it from did the same as me bought it then just sat on it.

Hi Kyle, thanks for the tip. The 475Be does not sound as good as the TAD 2001, 
even with the shorter throat. The Beyma CP380 is actually very good for this horn, and much cheaper.

Best Regards,
RB

LS-1209 was £266 each ex. VAT and LS-6503 was £206 each ex. VAT.


The Radian Beryllium might be worth a look for a fancy option that fits a little better
