mark1101 Posted June 12, 2023 Share Posted June 12, 2023 I'd think twice about mounting an AXI on a 510. Can't you buy another 691 from Klipsch? Quote Link to comment Share on other sites More sharing options...

I believe @MMurg has these on the 18x10's with good results and those are similar to the 510 I believe Quote Link to comment Share on other sites More sharing options...

The 691 is a rebadged B&C de75 with a "hardened" diaphragm and according to the Chief can be substituted without crossover changes. The original B&C de75-8p has been discontinued but there is a couple newer options I'm just not sure how close they are to the one Klipsch used: https://usspeaker.com/B&C-DE75PTN-1.htm https://www.parts-express.com/B-C-DE750TN-8-2-Titanium-Horn-Driver-8-Ohm-4-Bolt-294-615?quantity=1 Quote Link to comment Share on other sites More sharing options...
diamonddelts Posted June 13, 2023 Author Share Posted June 13, 2023 Sorry for confusion. Using a 3 way crossover from Klipsch with KT-1133 HP on 402 and K-691 on 510. I would like to keep 3 way setup but switch the K691 with another driver. Could the Faital Pro HF-200 work as a drop in replacement on the 510? Doing some last minute tinkering before I make final decision to stay or move on to other options. Quote Link to comment Share on other sites More sharing options...

Regardless, the Axi2050 is not an appropriate "drop in" replacement for the K-691 if using the existing passive crossover. 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted June 13, 2023 Share Posted June 13, 2023 @diamonddelts you have done a lot of "tinkering" to use your word with these speakers and it seems to me you were never happy. I THINK the crossover you have is for behind the movie screen applications. What have you done to correct for the boosted high end? Quote Link to comment Share on other sites More sharing options...

I'm only using my prepros onboard eq to dial back some of the hf. But often times I turn the eq off. I like my treble a little hot. It's hard for me to leave things alone and it's always in my nature to see if there's any incremental increases in performance to be had. It's the reason i've owned over sixty different speakers and subwoofers. I also routinely redo my home gym yearly. I will also update high end tvs and commercial blenders at the drop of a hat. And I've been known to redecorate a entire house because I bought one new rug. It drives my family crazy. Lol. 2 Quote Link to comment Share on other sites More sharing options...

I'm kind of in the same boat with my custom kpt-325's behind the screen factory passive crossovers slight bass boost, minus one on the treble dial and running tube amps make them sing beautifully. I swapped out the k-48's for some nice Beyma 15's awhile back and wow what a difference mostly in the upper bass and lower midrange I wasn't expecting that but they keep up and blend with the compression drivers much better now. Of course that got me thinking about compression driver upgrades but my set up really sounds the best it ever has and I like the simplicity of passive crossovers plug and play maybe some day I'll get the itch and go active, open the door for more experiments. 1 Quote Link to comment Share on other sites More sharing options...
diamonddelts Posted June 15, 2023 Author Share Posted June 15, 2023 Anyone think the Faital Pro HF-200 is a better driver than the K-691? In terms of one on one comparison between the two? Quote Link to comment Share on other sites More sharing options...
