All speakers have a little EQ built in


It may come as a shock to audio purists but part of the work of a crossover is level matching as well as tonal adjustments of individual drivers.  Ahem.  That's what we call equalization. 

This is true whether the speaker uses active or passive crossover, and may be in place just to adjust phase matching in the crossover range.

Also, curiously, while companies may brag about the number of parts in their crossovers, more parts does not indicate more quality.  It may just indicate more equalization had to be done to the drivers to get them to match.

@elliottbnewcombjr I’m with you 100% on the AR’s, I used to listen to the Nightbird on AR 4’s. I restored the 2 AX’s and they help reinforce that hi-fi hasn’t changed as much as some people think in the last 50 years. :-) I had to recon the woofers, but the mid and tweeters were fine. What tweeters did you choose to replace yours with and how do they compare with the originals?

nice thread Nigel and I like your blog, but I wish it were a little easier to navigate the related articles in the order in which you wrote them. @erik_squires  DIY And another nice layer of fun to this hobby and can save a heck of a lot of money.

@dougsat I agree. Since building two pairs of open baffle, single driver speakers with no crossovers, I have found that they have virtues that sit them equal to my LS 50s, Klipsch heresy, ones, and AR 2AX’s. I also have measured my hearing and have a slight rolloff beginning at 4000 Hz and continuing through eight and above. Using Roon, I crafted a compensation curve and have been switching it in and out and come to the conclusion that I rather like it on most recordings. So a “flat response “is appealing in some cases butI have found that there are also things to be gained by allowing one self to move away and explore other avenues.
