tigerwoodKhorns Posted November 25, 2005 Share Posted November 25, 2005 The title says it all. Are JBL 2470's superior to the K55. They have a 1" throat and go down to 300hz (at least for voices). ANy experience with these? I plan to use them with ALtec 511's in K horns. thanks, Chrris Quote Link to comment Share on other sites More sharing options...
djk Posted November 25, 2005 Share Posted November 25, 2005 They sound great! Make sure they have the original diaphragms.Most people put in titanium when they blow, they don't sound as good. The original 2470 diaphragm lists for about $242 (each). Quote Link to comment Share on other sites More sharing options...

Al Klappenberger Posted November 27, 2005 Share Posted November 27, 2005 Chris, That driver should really work well in place of the K55. You will have to drill some holes in the Altec flange though. JBL uses a 3-hole mounting scheme. I assume the 2470 uses that. The Altec scheme used 2 studs. I would love to hear how those would sound on my Trachorn. They would mount right up to those with no adaptor. Al K. Quote Link to comment Share on other sites More sharing options...

dubai2000 Posted November 28, 2005 Share Posted November 28, 2005 Isn't there any adaptor which I could use on my University (EV) horns?......I'd rather not drill into them. Wolfram Quote Link to comment Share on other sites More sharing options...
D-MAN Posted November 28, 2005 Share Posted November 28, 2005 Wolfram, you could make an adaptor plate, one side mounts to the horn as usual, and the other is for the 3-bolt driver. I tonly need to be as deep. DM Quote Link to comment Share on other sites More sharing options...
dubai2000 Posted November 28, 2005 Share Posted November 28, 2005 D-Man, great suggestion, but.....somehow I seem to have two left hands when it comes to such DIY jobs [], plus the EV horn is just like the original Klipsch horn....drivers have to be screwed in.

D-MAN Posted November 28, 2005 Share Posted November 28, 2005 Well that's even easier! Glue a screw-on thread portion to the plate and drill it with the 3-holes for the JBL, and your ready to rock! I know - you don't want to build it yourself, but it seems like it would be easy to do, if you get a wild hair someday. DM Quote Link to comment Share on other sites More sharing options...
djk Posted November 29, 2005 Share Posted November 29, 2005 Selenium AD25-25, under $5 (for JBL/Altec to EV/University). The CLS 'C' plate, 1" 3-bolt JBL to 1" 2-bolt Altec, price unknown. This is a 1/8" thick aluminum plate with two studs on the Altec pattern, and three countersunk flatheads for the JBL pattern. A possible DIY project, one could buy the Selenium, turn down the threads, tap for 1/4-20 studs and countersink. If you drill a 511B it will be tight fit (allen headed cap screws).

Al Klappenberger Posted November 29, 2005 Share Posted November 29, 2005 Guys, Chris is generously having the JBL drivers shiped to me first. I have the adaptor plate djk described and I will run curves on them on the K400 horn and on my Trachorn as soon as I get them. Stay tuned! Al K.

dubai2000 Posted November 29, 2005 Share Posted November 29, 2005 Great info on the adaptor.....Thanks!!! I am looking forward to more infos on the drivers - which I take are possible direct replacements for the K 55 using Al's A networks (no problems because of 16 Ohm?), right?

Al Klappenberger Posted November 29, 2005 Share Posted November 29, 2005 No problem. Any of my networks will run any quality squawker driver no matter the impedance just by moving the transformer tap settings. AL K. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted November 29, 2005 Share Posted November 29, 2005 Al, Looking forward to what you see (and hear) when you get the Altecs on the Trachorns. One thing about the Altecs exceeding the K55 in performance... it makes the K55 look like a huge bang for the buck winner. $242 for a single diaphragm. Ouch. The Altecs certainly should sound better.

dubai2000 Posted November 29, 2005 Share Posted November 29, 2005 Thanks Al for clarification. This does indeed sound like yet another future project! Looks like this will never end []. Wolfram Quote Link to comment Share on other sites More sharing options...

dubai2000 Posted November 30, 2005 Share Posted November 30, 2005 Curves don't tell me enough, so it would be nice if someone had the chance to compare those two drivers and report back. Wolfram Quote Link to comment Share on other sites More sharing options...
ZAKO Posted November 30, 2005 Share Posted November 30, 2005 Ive compaired the 2470 & K55M ...On K401 horn...Both sound simmiler, to close to make a real difference. On a different horn like the Altec 511 or 811 maybe better resolution Could be heard. I also used my favorite Smith DSH horn the JBL 2397 with no improvement . The drivers ar,nt bad but not in the same league with the resolution of Beryllium or aluminum diaphrams. Quote Link to comment Share on other sites More sharing options...
