Old thread but others will follow for the information so let us get it straight without debate-

I am inclined to a tuning compromise like 35hz- but I will await measurements based on the new HT speakers/placement.
Thanks Lee!:bouncy:
Went ahead and picked up a 2240 to get started- not too expensive and I know it can be later re-coned to a 2245 should I require something that goes lower. I like the Idea that the 2240 may be...
I believe this is the ceramic version and the last Alnico were the "C" (not "C" for ceramic, just the line after "Z" & "B"
get a pair of AMT1's. Then go with the previous suggestions which include a 123a out of an L100 or an Altec 414 and replace the existing midbass of the AMT1. This simplifies things immensely. Keep...
This was supposed to have been a response to the last post the chain: 2 Way using AMT Heil-
I was not trying to reply to my own post! Now the board will not allow me to delete it as it has already...
Get yourself a pair of AMT1's. Drop an Altec 414c where the woofer is. Keep the passive. You are on your way. When you have the time/motivation/inspiration go ahead and start experimenting with a...
Thanks- Yes, I have read good things about this design. I will need to pass on that for now so I can use the drivers I already have. If only we could know what experience and inspiration would have...
So far we have agreement on multiple subs. To that I would like to add a quote from Siegfried Linkwitz:"...the modulation envelope is subjectively preserved more frequently with the dipole..."
"This...
I know I can muddy up questions but I appreciate your input and I think I get it:
Open Baffle- good, Multiple woofers in different locations- for smoothing time and frequency response, particularly...
I will look into this. Seems like an interesting solution. But your not saying I do not have the traditional main woofers under my mid/tweeter arrangement for the notes above say 60 hz? Then, if I am...
Thanks. I am aware the Vandersteen 2W is highly regarded and uses (3) 10" : any box & driver suggestions besides purchasing two of these? (a big financial stretch) to get that level of transient...
I have been working on a project for awhile and I am approaching satisfaction. I am using an Altec 414c with a large Ess Heil air motion transformer. Imaging is not great due to the relative sizes of...
I am new as well and have already made a two way using the Heil series 1C, upgraded crossover parts on the original AMT crossover (Madisound) and used an Altec 414c mid/woofer due to its quickness....
I was spending too much time and money so gave up trying Altec crossovers and even active (fried a good amp with a shorted patch cord). So went back to the original AMT crossover and upgraded the...
If keeping to the original design/two way with passive I would use an altec 414c for the mid/woof. I am new here but the explanation was the Heil being super quick needs the fastest midrange you can...
