Which driver for Onken or VOT?

souldriver · 26th July 2011, 09:43 AM

Hi
I have a Iwatahorn 300 with a Radian 950 PB driver and i am looking for the best audioquality for the mid-/bass and bass frequencies. i think that Onken or VOT would go perefectly with The Iwata's but it is very difficult to find some old Altecs 416A or 515 in good quality. I would like to know which other drivers you would suggest for Onken or VOT?

Thanks a lot for answering

The Supravox drivers are designed for Onken.

Great Plains Audio makes 515 series drivers that are highly suitable, as did Iconic (165 series).

There are also a number of drivers from Eminence that have reasonable TS parameters for these sorts of alignments. I believe that B&C may also have several suitable models, but have not checked recently.

Plus GP's 411, 414, 416, 421 series if they can still assemble per original specs listed here: Thiele/Small Parameters for Altec LF Loudspeakers

Regardless, one can use WinISD Pro or similar to check drivers to see if they are suitable by selecting a Qb3 alignment with [6-8] vents totaling [0.75-1.0x] driver area [Sd] that don't exceed ~35 cm long.

Ditto what Kevin and Greg said. You can use a box simulator to "try before you buy" be using the parameters listed above. You can think of the original Onken as a 340L bass reflex tuned to 39Hz.

The nice thing about the 416 was its high efficiency and low Fs. If you don't get a modern 416, then look for something like it. Most pro 15s have a higher Fs than the Altec.

Thanks a lot for your advise. i will give try to check out these thiele /small parameters with some other speakers. i think it is quit difficult (after reading some treads about the Onken) to find other speakers then Altecs or GPA's. Yes, the Supravox could be a possibility but somebody wrote that the 285 does not go below 50hz which is not enough for me. on the other hand i will have a closer look to open baffles design. i guess with 4 18' Dipoles i could get some nice performance as well. il keep you informed. any further adises will be veeery welcome. thanks again!
