Gregg357 Posted March 27, 2014 Share Posted March 27, 2014 (edited) Awhile back I upped an old pair of hii's to hiii's with the klipsch kit. I've recently bought a set of forte ii's. I've read the popular mod's and am a big fan of alk's xo's and plan to put alk's forte xo's in my set. Question, once I install the alk forte xo's, can I simply swap my hiii and fii tweeter and squawker diaphragms? The goal is to maximize the fortes, while the heresies do bedroom duty, for the least $. Thanks, Gregg Edited March 27, 2014 by Gregg357 1 Quote Link to comment Share on other sites More sharing options...

Gregg357 Posted March 27, 2014 Author Share Posted March 27, 2014 Great, thanks. I thought that's how I had read the other posts. One follow-up please, I figured it was ok to put the newer Ti dia's into the Forte II, what I'm most concerned with is putting the old Forte polymer and phenolic dia's into the Heresy III drivers. Will those old polymer and phenolic dia's be ok in the larger magnets and work within the scope of the Heresy III xo? Thank you, Gregg Quote Link to comment Share on other sites More sharing options...
moray james Posted March 27, 2014 Share Posted March 27, 2014 (edited) yes they will, however the crossover in the H3 is tweaked for the balance of the ti mid diaphragm but both the mid and tweeter diaphragms are the same from a physical fit point of view.

djk Posted March 27, 2014 Share Posted March 27, 2014 (edited) Just remember there will be a peak around 7Khz until you get the new crossover in. Edited March 28, 2014 by djk Quote Link to comment Share on other sites More sharing options...
pzannucci Posted March 28, 2014 Share Posted March 28, 2014 You will need to put a low pass on the mid with the Ti diaphragm. That will get rid of that overlap and peak at 7K described, unless the new crossover was made for the Ti's extended upper end. Quote Link to comment Share on other sites More sharing options...
djk Posted March 28, 2014 Share Posted March 28, 2014 "and plan to put alk's forte xo's in my set." The ALK Forte network has a low-pass filter on the mid. Quote Link to comment Share on other sites More sharing options...
Gregg357 Posted March 29, 2014 Author Share Posted March 29, 2014 I ordered Al's forte ii xo's yesterday, can't wait. I tend to over do things for no reason, as such, am interested in anyone's thoughts on Bob Crites' forte ii woofer. is it a sonic upgrade over the oem woofer or more so a compatible/suitable replacement driver if the oem driver were to fail in some manner? thoughts?

John Chi-town Posted March 30, 2014 Share Posted March 30, 2014 If I am not mistaken it is simply a replacement. I will be very surprised if you are not thouroghly satisfied with the upgraded X overs, and titanium diaphragms. I to own forte II and have done all of the upgrades you described a few years ago.

John Chi-town Posted March 30, 2014 Share Posted March 30, 2014 At what point does the ALK crossover roll off the squawker? Best regards, John Quote Link to comment Share on other sites More sharing options...
Gregg357 Posted March 30, 2014 Author Share Posted March 30, 2014 (edited) I'm buying then, so you'd think I know. But, I don't. I think they roll off just short of 7khz. I think they are 650hz/7000hz xo's. I agree, I fully expect to enjoy them. I've got some alk eskhorn xo's that are spectacular.

Gregg357 Posted April 16, 2014 Author Share Posted April 16, 2014 ok, i'd like to revisit this. i'm asking before I open the cabinets which is either prudent or lazy. take your pick. I want the best driver sets out of this group of four speaker pairs. again I haven't opened them and don't know bolt patterns. the question is primarily xo based I think. i've got 1 pr stock forte, 1 pr stock forte 2, 2 pr heresy 2's upped with the heresy 3 kits. i've ordered 1 pr alk forte 1/2 specific xo for the forte 2. prob get another set for the fortes, also. can I, put the k-107-ti's with the k-53-ti's in the forte sets (forte 2 I would swap squawker horns if bolt pattern same, else swap diaphragms) with the respective woofers run by the alk xos? this would leave k-75-k's (one set phenolic and one set polymer) plus k-53-k's (both phenolic) with the k-28-e's run by the heresy 3 850hz/5000hz xo. probably an exercise in futility, but if the heresy 3 xo can work with that driver set and the alk forte 1/2 xo can work with that driver set, on paper it would seem the highest and best use of each magnet/diaphragm/horn combo. lastly, the two forte sets are not played together in the same system. the four heresy are played together. for what that's worth. thoughts?
