Searching for midrange duty...
Hi, In my a previous set up I used Altec 420a as midrange drivers and really enjoyed them. I sadly had to sell that system a couple years ago, I am now in search of a midrange driver with some of the same smooth qualities but at a less expensive in price. Are there any such units you would recommend using between an Altec 416-8a and an Emilar EA-175/EH800 combo? Vintage paper cones with alnico motors are very appealing to me.
Thanks for looking

The 416 actually goes higher than some 12's.
ALTEC 406-8Y 10" often show up on eBay for around $200 the pair.
Note- earlier 406 have a 2 inch voice coil. 3 inch on the 8y. The older 406 are slightly less efficient than the 416. 8y are almost identical.

Thanks Old Guy, I?ll look into that one for sure

Hmm, mids = 250-2 kHz = [250*2000] = ~707 Hz mean power distribution = ~13543/pi/707 = 6" effective diameter, so the pioneer's 8" is close enough. Now if there was such a thing as reasonably priced 755 series. :(

Reasonably priced 755... that’s not asking for much! Do you have a particular Pioneer unit in mind?

Is that 8 inch going to be able to keep up with a 416? Most are around 6 dB less efficient.
Re: Searching for midrange duty...
Good question, I?d hate to waste any precious low frequency energy in the form of backing off the efficiency to a meet the midrange driver

The original, but not a realistic option nowadays. :(

Well, unless one uses DSP the HF sets the system efficiency, which once EQ'd flat is 'only' ~96 dB and the original W.E. 755 is 95 dB from ~300-10 kHz, so close enough and any extra woofer efficiency can be used for baffle step compensation [BSC] if required.
All academic though.............
Anyway, I imagine JBL has something usable in their cinema series if none of the old Altecs pan out and the DIYers are loving this one mated to a small WG for compact two way studio monitors or as mids in larger 3-4 ways: https://www.parts-express.com/pedocs...spec-sheet.pdf
