twistedcrankcammer Posted June 10, 2014 Share Posted June 10, 2014 (edited) Anyone familiar which model Stephens Truesonic subwoofer was installed in early Klipschorns?? Roger Edited June 10, 2014 by twistedcrankcammer Quote Link to comment Share on other sites More sharing options...
seti Posted June 10, 2014 Share Posted June 10, 2014 The blue trusonic woofers used in the khorns was pretty dam good. I think funkyhambone has some trusonic stuff. He runs the trusonics in his short horn 3 way system and it is really good.....Woofer is a 102d? Quote Link to comment Share on other sites More sharing options...
mungkiman Posted June 10, 2014 Share Posted June 10, 2014 My understanding is 103LX or 103LX2. Quote Link to comment Share on other sites More sharing options...
Budman Posted June 10, 2014 Share Posted June 10, 2014 just googled it and an ad came up with a stevens woofer out of a 54 k-horn was a model 103 Quote Link to comment Share on other sites More sharing options...
twistedcrankcammer Posted June 10, 2014 Author Share Posted June 10, 2014 Any pictures or distinguishing factors?? I'm looking for a pair for an early pair of K-Horns Roger Quote Link to comment Share on other sites More sharing options...
Budman Posted June 10, 2014 Share Posted June 10, 2014 (edited) can't miss them a lot of them are blue in color. ebays completed items page has a bunch of them Edited June 10, 2014 by Budman Quote Link to comment Share on other sites More sharing options...
mungkiman Posted June 10, 2014 Share Posted June 10, 2014 It's my further understanding that 103LX are 16 Ohm and 103 LX2 are 8 Ohm. Quote Link to comment Share on other sites More sharing options...

seti Posted June 11, 2014 Share Posted June 11, 2014 Found in shorthorns.. Quote Link to comment Share on other sites More sharing options...
mungkiman Posted June 11, 2014 Share Posted June 11, 2014 And Klipschorns. If "period" networks aren't in play, the 103 LX2 woofers are what you want, Best of luck! Quote Link to comment Share on other sites More sharing options...
kuisis Posted June 14, 2014 Share Posted June 14, 2014 I'll check my 54 tomorrow, I'm almost sure it's the 103lx, since they are 16 Ohm. Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted June 18, 2014 Share Posted June 18, 2014 Make sure you get one that's 4 (actually more like 3.2) ohms. I think it's the 103LX version. Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted June 18, 2014 Share Posted June 18, 2014 Let me clarify myself. Sitting on the table, the 103LX, and the EV 15WK, for that matter, should read in the 3-4 ohm range. The horn loading increases the impedance when the speaker is in use. I tried putting 16 ohm Altec 515s in my Shorthorns once. You could barely hear them.

This is for an early pair of Klipschorns that could have come with the Tru-Sonic woofers, so yes, period networks are in play. Thanks...

I have a pair of perfect, early EV 15W-K woofers, but I need the correct early Tru-Sonic woofers for a friend. Thanks... Roger Quote Link to comment Share on other sites More sharing options...

dbgallup Posted November 17, 2016 Share Posted November 17, 2016 I have a question for Captain Bob or anyone: is there a way to lower the impedance of a speaker? I am new to all this and have a 8-ohm Trusonic 150 Fr I put in a corner horn and the results are not as good as hoped. The enclosure is not a stock Khorn but very much like it The speaker sounds a bit muffled and the bass is hard to find. I was wondering if the problem was with the impedance, of some other issue. This is my first post and if I sound like ignoramus it is because I am. Any advice would be most appreciated, and thanks in advance.

Ski Bum Posted November 17, 2016 Share Posted November 17, 2016 You can use a transformer to change the overall impedance presented, similar to how they are used with certain electrostatic or panel speakers that were otherwise notable amp-busters. In those cases, the transformer was to raise the speaker's impedance, but the same principle applies if you're trying to lower it. It's impossible to say if the bass issue is impedance related. Chances are it's a speaker or speaker/room coupling issue. Further assessment is called for before implementing solutions, me thinks.

Tom Mobley Posted November 19, 2016 Share Posted November 19, 2016 Dan from Pasadena, you know anything about old Chevy pickups? Quote Link to comment Share on other sites More sharing options...
dbgallup Posted November 25, 2016 Share Posted November 25, 2016 Thanks Ski Bum. I replaced the Trusonic 150 FR with an EV 15 Wk and got a noticeable improvement in performance. These are kind of hard to find, so I don't think I will build a second enclosure unless one comes up. Tom, these Trusonics do sound old and tired, if that was your point. If you had something else in mind, I'm too stupid to figure it out. But I have bought a book from Amazon on speaker cabinets and hope to be a lot smarter in the future.
