Multiple Altec 416 sub?

[Datubie]

Right now my bass comes from a set of Onken "W" bins with two Maxonic 15" (Altec 515 style Field coils. See avatar) each that work up to 250hz.

I have 3 pairs of Altec 416Z (16ohm, 15") that I was thinking of using in a pair of subs for hifi, working from about 50hz down.

I have space constraints of 2ft wide X 3ft deep X 6ft tall. What kind of enclosure would you suggest? I've seen those line array subs and those look like they'll fit.

If you link to their complete T/S specs (or measured) maybe I can give you some help.
I only have specs for their 8 Ohms brothers.

If they were connected (maybe not as a sub<50Hz) in pairs for their vintage setup 8 Ohms systems look at their dimensions. Also, if the Altec Valencia had a 416Z maybe a relative enclosure tunned the approximate frequency will work.

If using the parameters for the similar Altec 416-8B instead (Altec 416Z), there are 4+ different versions of this driver.

If ablind project, you can start with a bass reflex enclosure VB = 156.0 L tunned to FB = 28.4 Hz (ideal not sub) with F-3 dB 44 Hz or FB = 35.3 Hz with F-3 dB 41 Hz. Good luck.

Are you looking to supplement the Onken W with the four 416Z? The W doesn't go low enough? The pair I used in Paris went plenty deep for me. I can't remember if they used 515 or 416 drivers.

Have you tried the 416s in the W? Or is this for some other use?

Here 416-8B with 550 Hz crossover in a medium size auditorium (+Altec 288-16K CD with Iwata horn and Raal 140-5D) in a bi-amp setup with Siemens C3m/Telefunken EL3010 vacuum pentode for the tweeter stage. The sound (stage) was pretty much good and "Symphonic" and with a scent of "vintage poetic" almost perfect. (Dec2012)

Really nice room, too. I bet it sounds great.

@Inductor. I don't have the T/S for the 416Z, but they are just commercial versions of the 416A.

@Pano. Yes I am looking to supplement the Onken "W". I want to limit them to 2-3 oct range.

OK. I've heard them low passed at ~120 and also low passed at about 700Hz. Either way, the best woofer I've ever heard.

Do you plan to high pass them to mate with the 416 subs?

When do I get to come visit?

You won't get subwoofer type bass from a 416. It was designed for high efficiency not deep bass.

 

[Pano]

I agree. Even in 11 cu ft cabs that mine are in, I struggle to get to 35Hz. But maybe that's enough for Datubie? Maybe he wants to limit how low the field-coil drivers go.

 

[Datubie]

Yeah, that's what I thought too. They are just lying around doing nothing, so I am thinking of using them for something.

Thanks for the replies anyway.
