2216Nd Projects

[pos]

Questions for you DIY types with real world experience with the 2216Nd... after my off the wall suggestion Rob (sebackman) to try to EQ the snot out of the 2216Nd for sub use, I pulled up this old thread.

While the 2216Nd is definitely not a true sub, it looks like it will certainly get well below 30Hz with authority and in my listening to the M2 with factory calibration, being most impressed with the LF I am curious what you guys have found the lower limits to be. What tunings and enclosure volumes are you guys using?

I've never tried it as a sub myself.
There are probably cheaper options out there to use as subs, and arguably better for high SPL or to go very low (both of which are probably of no use for music at home).

There is one thing I think the 2216nd would be very good at: accompanying another 2216nd as a "flanking sub".
I think this is a term Wayne Parham from Pi Speakers first came up with, and is pretty similar to what JBL does in the 4435: a helper woofer.
Basically an additional woofer put close to the existing one that plays together (and in a similar alignment) with the main one, going as high as possible and stopping just before it can be located as a different source.

IIRC integrating an additional 2216nd with an M2 is theoretically very straightforward: you basically put a 1st order LP at around 100Hz on it, and remove the shelving filter from the LF crossover section of the M2.
It is almost like it was meant to be done

EDIT: If this was not obvious enough, I am just trying to help you find an excuse to buy a pair

Just thinking of potential projects and that I should get a pair of the 2216Nds before the fine folks at JBL make this wonderful woofer NLA.

Hello Widget

I have them in the same alignment as the B380. The box is low tuned to 26Hz with EQ Q2 26Hz +6db. Doing a sine sweep useable in room to 20Hz where the sweep stops. My f3 is 25Hz using the full +6 and have a +3 preset as well. So 0 +3 and +6. For music I can't see ever running into an issue.

For LFE?? Depends on how low, levels and room size.

They are darn good but just going back to using 2 B380's and ringing the mass rings on Tron and Master and Commander. Ended up using a pair of Vertec 2266 woofers with greater X max no issues smaller boxes.

If you already have a pair you can try them and see.

If you don't I would look at a real sub driver instead of dropping $800 on another pair for a could be.

I like your thinking!

I haven't worked on any new DIY projects in over 15 years. I have plans to build a pair of vintage styled L300s in L200 enclosures with a bump out for the 2312 horn. They will be bi or tri-amped, controlled by DSP, and will most certainly not be an ultimate sonic statement, but something I want to do for the fun of it. Since mint 136A/2231As are not in my collection and finding or recreating a pair is extremely remote, I will need to find a suitable woofer. I have a pair of 1501ALs that will likely be put to use in this project.

All that aside, I really like the sound I've heard from the 2216Nd and am thinking I may try a new DIY based on them. Based on the earlier posts in this thread and info from other threads, unless you have a very large room or need exceptional SPLs in the VLF range it seems a pair of 2216Nds will happily get you from the lowest frequency demands of most music to 800Hz.

I think I have found the excuse I needed. Thank you both!

Hello Widget

I have a spare pair if that helps

I have been thinking on adding another 2216 myself. I already have the woofer and matching amp, just need some time.

Here is the post you gave more specifics on how to integrate another pair: https://www.audioheritage.org/vbulle...l=1#post405011

You really think you need one or are you just doing a 4435 "upgrade"?

Not really, I got the 2216nd's in a trade and figured it would be fun to try out.

What I really need is a different room to put them in.
