O.K its been a long time since I joined and follow this excellent forum, and I feel it is time to ask for some help on a design I am working in my mind for some time.
I got to tell I am into high efficiency speakers, 2 way at most and low power amps like less than 20W. My quest so far led me to horn loaded 15" tannoy dual concentric design I enjoy listening at, all the time. I am now ready to go into a different approach. I am about to design a 2 way bass reflex system with a 15" or 12" LF woofer paired with an HF compression driver I already have(altec 806a), matted to a 811B horn(i know I am "cheap").
I would like to ask for any proposals as far as the LF is concerned, I prefer older high effieciency woofers like 130A, D130, 2220(seems identical to 130A) and 2205. Which of these(or others) do you propose for this simple system? I really prefer alnico and non foam souround.
I was after a pair of K145s for some time but seems very difficult to locate a pair. Moreover, if anybody here is willing to part with such a "vintage" pair I am all ears. I recently located an 2205 pair that seems nice according to T/S parameters and an e145 pair that seems low sensitivity model but in excellent optical condition. I also think altec 515 and 416 may do nicely as well as TAD and Precision Devices although I prefer something from JBL. Please throw some light to my darkness...
