2435 HPL- 2 way 750hz

[Zilch]

They ARE the compensation, Mats, for 2435HPL on PT-x1010 waveguides. They must be used with either an active or passive XO. I'm running them on M552 at 1 kHz, presently, and have posted the FR curves.

Here's six different eBay 2435s on PT-H1010 using this filter:

I'm trying PT-F1010s with it right now.

Other members are working on similar designs. I'm not done fine tuning these, either, but I wouldn't hesitate to recommend them as a starting point for anyone wanting to play this driver on these waveguides. The cost is under $100 a pair for parts to build them.

The original (somewhat different) version developed by Greg Timbers is optimized for a particular JBL consumer horn, due here in March:

Ok i see. I have both a jbl 553 and a Dbx Dr pa to go with. I will continue too read this thread for more info to my own project.

Note: My M55x series active crossovers all had the subsonic highpass filter enabled.

May want to check that....

Edit: Oops, it's 15 Hz. Guess I'll turn them back on....

This is maybe a stupid question, but does these filters have some eq compensation for the horns ? I´m figuring to drive with active xo.

mats

Whether it is or not, I think the point is that the filter could be used in the cabinet with the drivers to smooth the response and an external active filter of generic nature could be use to achieve the frequency division. If I were doing one of these, I would set them up for biwiring/biamping and use an external active crossover.

I will have mine all biamp. I´m not so good in passive filters so i have to ask about it. I got confused when i saw zilch had a m552 too do the hipass.

No problem, Mats.

Compensation has to be provided somewhere, and this seems a far better approach than using external EQ as was earlier recommended. As Dave points out, the actual crossover becomes "generic."

If you look back to when Giskard first posted the filter, it took me a while to get clear on the concept of isolating the compensation, too!

I wish i was as good as you on filters zilch, but i have a lot to learn.

Hang in, Mats. What I know I learned from these forums. It's all here or referenced here.

[I certainly don't have it "knocked," either, just enough to do stuff with some confidence.... ]

when setting our eq for the 2435....do u think we should start out with these settings?

look how flat they got the response, lol....

I would not use Vertec EQ on AM6200, no.

Use the AM6200 passive filter, and simply cross to it at the recommended frequency as starting point....

I am thinking of giving the yuichi a290 horn a try on the 2435 but the pdf file is not very clear and the vanes mesurements are not there, does someone have complete plans? help would most appreciated

[yggdrasil]

Are you aware that the Yuichi A290 horn plans are for 2" throat?

Yes I do Johnny,What I plan to do -there is 5 segments in this horn,each segment = 20% of the horn area so I then add one more vane to it . going from a 90 deg horn to 108 deg. or a 6 segment horn, then reducing the height of the horn 20%- 2" to 1.6" Do you think it will work ?

[DJ Vincenzo]

ill post up the 2435s with the am6200/95 wave giude in a week or 2 when my friend brings over siasoft.

the only EQ-ing i did to achieve this was simple.....x-over at 1500 (Linkwitz-Riley 24) and 2 PEQ filters.....

1. BAND filter - 750 htz @ 3.5 db / BW .500 (Q=2.87)
2. HI SHELF filter - 8000 htz @ 8.0 db / BW .325 (Q=4.43)

End result..

2 - 2435 hpl's 200 watts each (10.6 ohms)
2 - 2250 h's 500 watts each (8 ohms)
6 - 2226 h's 1250 watts each (6 ohms)
4 - 2268 h's 2400 watts each (4 ohms)

thanks to Lang Holland from Soundscapes for spending 6 hours to tweak my system.....and thanks to that bad arse 2200$ condenser mic he had, lol.
