ok so dont laugh, i have a pair l200 cab and i want to install le15b and le85 drivers and a pair of 046ti tweeters with lx-13 cross overs i will cap the 046ti tweeters off the le85 horns. good idea or not.

Most folks toss a pair of 2405 Slot drivers in the L200 cab - building a quasi L300/4333 out of it ... of course, its not perfect because it has the short horn and not the long horn used in the L300/4333, but it can be mighty good.
If you go that route and don't have a crossover, you can build a pair of 3133 crossovers ...
Details on things I've done with mine can be found here ...

- It's been done before ( mixing HiFi tweets & SR compression drivers with horns ), by a long time LHF member / with a large measure of satisfaction .Originally Posted by dwight8
- Read this thread about Sebackman(s)' HT setup .
- BTW, since he was running an all active system / he had the ability to level match the tweets to the rest of his components ( even though they are a good 6 db lower in sensitivity than the rest ) .
- JBL themselves have (had ) something similar ( to Sebackman ) in one of their older HT systems ( S1M Synthesis ) .
- It differed in that the mid/tweeter combo ( or the horn ) were switched in & out of the circuit depending on the systems' intended useage ( HT or music playback ) .
- Here's the S1M schematic to look at .
- Sebackmans & JBLs approaches to using HiFi tweeters with HT ( SR ) components are both pretty sophisticated.
- Follow either example for best results .
- ( ie; I'd advise that you avoid your proposed wire-up scheme / you're most likely going to blowup those ( expensive ) tweets /especially if you are thinking that a single cap will suffice as a HT crossover ) .

- If you're going to try using your 046Ti after a passive network, I would suggest that you build something like a 18 db/octave ( 3 element ) filter designed to crossover around 10K . Run signal straight into it from the amp source ( don't pull it from the signal feeding the le85 / this signal feeding the horn driver is attenuated , which you don't want since you'll want every db available to you .
- Making the network a bit of a 3-pole "bump filter",( maybe peaking at 13K ) might help you hear the tweeter working . Maybe someone with LEAP will help you out here with a bit of design prowess .
- To properly design the filter, you need to know the AC impedance of the tweeter in the freq. range that the filters' passives react ( approx. +/- an octave from the F3 point ) .
- 4313B ( Giskard ) posted the AC impedance of this tweeter ages ago / & for the life of me, I can't dig it up using the search function .
- As I recall it was really quite flat ( & was something like 6 ohms ) .
- Does anyone know where to find it ?
>< cheers
ps; OTOH, Heathers' practical advice makes the most sense .
ok so how about useing a L100 cross over for the 046ti only does any one have a pair jbl N333 or 3133 cross over for sale? i cant even make sence let alone a cross over lolor may be i will just sell the 046tis what do you guys think there worth, there like new
- No ! ( that's almost a guaranteed situation that will allow too much signal into the 046Ti / then poof ! ) .ok so how about useing a L100 cross over for the 046ti (?)
- Yea, likely best to sell them and put the money towards something you won't too easily blow up ( like 2405s ) .may be i will just sell the 046tis what do you guys think there worth, there like new
- eBay ( as always ) establishes the going rate for these sort of items .
>< cheers
are the 0465ti worth as much as the 4205?

ok i got a pair of L166 for my center channle my mains are custem built s8 do you think i should replaces the tweeters in the L166 with the 046ti tweeters but im still looking to buy a pair of 077 or 2405 tweeters
