I'm sure you'll get them treaked. If you have LSPCad or Loudpeaker Lab or some software with a calibrated mic, the crossover may need to be looked at. I never got the Lambdas right with a passive crossovewr. That is why I am looking at the digital crossover and EQ. Do you have anyone local who is a speaker design guru, if you don't have the software? That's what I'd try, PLUS the drivers have not fully broken in yet. I'd play some pink or white noise through them for hours on end to get everything loosened up in them...
I really do not think damping will fully solve your response problems...but that is just my guess...I'd be looking for a designer...and maybe Danny Ritchie could get you closer with just the T/S params...although measureing with the calibrated mic is the only way to truly optimize the design, and the drivers will need to be broken in to do that precisely...
Great project, Mark......
You know, Al's "Universay Crossover" might work on this design? I don't know, but with some tweaking and maybe changing some values on the board, it might just work. He has the design on his website for free download..What does this speaker use for a crossover now? How was it conceived? Was it designed specifically for this speaker, and then tested with a calibrated mic running against the projected transfer? If you don't start with actual measurements from a mic, and are depending on published specs from a speaker maker...your crossever can be WAY off...You really have to measure the driver to get your own T/S numbrs and then FR to feed the crossover design portion of the software..

Sutton, I use an active crossover that is adjustable in both frequency and slope. The designer of these speakers tested them with these drivers and told me about the need for damping. I put damping in the bottom and behind the driver. The speaker puts out alot of volume just above 100 Hz and settles back down around 200 Hz. The damping pretty well cured this
You were typing while I was. See your PM's....Dialing the crossovers in will be the key...and if you are active, it sould be easy if you have a good spectrum analyzer with a good calibrated mic....and everything will change once the drivers break in..I need to go back and read this entire thread. I can't remember now if this is 2 way or three way, and if you are using the Crites woofers...and stamped or cast...I need to do some hojmework..
Geeod luck...they are going to sound fantastic.
The only driver I can find mentioned is the EV, which is the tweeter? Is it a 2 way with the EV and Crites woof? Or three way...With the pics all from inside, ouside, etc., it's hard to tell exactly what I was looking at. Reason I ask is I may be ordering the Crites woofers for the La Scala project, and would like to get the one used in these monsters so I can change them out if the La Scalas don't do it for me, or if these monsters end up being what I have a feeling they are going to be...
Thanks for all the info..

811 is the horn? Or driver? I am confused (as usual)...OK....tell me again....and are they horn loaded tweets? Horn loaded mids? (and I mean the Altec portion...I know the cabinets function as horn loading the drivers too)....but The EVX-155 is current production Electro Voice woofer...I just found it..fs is 35 hz...and has 5 star ratings...
OK....the EVX-155 is a 15 inch woofer with a 4 inch voice coil which is a monster...The 311 is an Altec midrange horn only...don't know what driver you are using...The 811 is an Altec horn for tweeters, and agin, don't know what you are using...and as you already know the 3 means crosser point of 300 hz, and the 8 means crossover point is 800 hz...although I knwo you don't have to do this.. I have a pair of 811B horns and some 808-8A tweeters....huh..........hhhhhhhhhmmmmmmmmmmmmmmmm
Link to the woofers...with specs and technical data..REALLY SOTA driver...is there a better deal out there?

Had to give them a 15 degree phase shift to get them in phase with the other horns. Drove them with a pair of Grommes 260's. Shit was falling off the upstairs walls and the cats were nowhere to be found. Neighbor came over to see what the hell was going on. I am going to hook up my PLWO 1000 to see what it sounds like as soon as the wife goes to the grandkids

So, he is pretty much a regular guy...He probably will love the speakers then. It might give his wife something to complain about, and him a reason to come over and hang out....so he can ask you to turn it down...Yeah, right...So, are they going to be THE "Desert Island" speaker? Or just a great speaker...leaving you still on the hunt? I think if we did find the perfect speaker, we'd still be on the hunt though...I'd love to hear them. Are they better than the Altecs now? They probably still have a lot of burning in to do..

Paralleled the altecs with the soniphase, Pretty impresive, tremendious bass with everything flat. The 700 at -5db was knocking shit off the walls upstairs and downstairs. With the tube Grommes 260's I had the same results, They are 60 watters. Great midbass, crossed over at 600 Hz and then 500Hz didn't notice any difference
