Hey Ivica
Thats new to me? Why didn't I see this earlier ?.. aha, it is brand new stuff; It has just been introduced by october 2014.
I wonder what its price gonna be.
Enclosure size 506 liters. Then tell me the dimension of the port to hit that tune. Thank you so much.
Henrik
Hi DynaMax,
Using BB6pro SW with 2 drivers in the box of Vb=506 Lit, and tuned Fb=27Hz, with rectangular port 20x35cm expected length= 31.1cm,
If applied 50Veff ( about 625W), about 130dB/1m would be expectable, max.air vent-speed about 10.6m/s around 23Hz, with almost 6dB
headroom for EQ from that frequency (and up), in Xmax, and Pmax, in order to compensate FR linearity at low frequency.
So using two boxes you can produce over 130dB/1m (attached figure about +6dB added to single box-repose),
from 23Hz and up, but the amp has to be minimum 2 x 2400W, if You decide to EQ about +6dB...
So, You can reproduce almost jet engine sound ( 140dB at about 33m distance) in your listening room. I believe that a kind of room effect would help too.

so, may be DD66k would become limitation factor, as their power rating of only 500W, ( using its efficiency of 96dB/1W/1m) can
deliver only 123 dB/1m/500W, but as You prefer a little more lower bass region, then such system can technically satisfy your needs.

Morning, All,
Yes, the Boz Scaggs "Dig" album is a fine one to hear some deep digital bass! Thanks to Heather for recommending it, a few years ago, and I have to say, we listen to it quite often, and always marvel at the great talent that is highlights on that album, from musicians, and the recording studio staff!! Excellent stuff! Take care, and God Bless!
Every Good Wish,
Doc
The only thing that can never be taken away from you, is your honor. Cherish it, in yourself, and in others.

Morning, Heather,
I had no idea that the original suggestion came from Zilch. So, I thank him, in absentia, and you, too! I very much miss having him here at LH, but know that someplace up there, he's probably looking down and smiling at our comments, and also our efforts to enjoy "real" bass on JBL systems!! May he rest in peace! Take care, and God Bless!
Every Good Wish,
Doc

If you're not afraid of a little structural damage, you can try the 24/176.4 version of Liszt/Prelude on B-A-C-H from Reference Recordings. This little ditty made me realize that a single BGW 602B wasn't near enough for my sub swarm. BTW, I take absolutely no responsibility for any system damage or involuntary bowel movements this cut may cause.
Hi Ivica
Thnak you so much. I will let you know when the system has been upgraded to the 2269H. 4 units has been ordered. Next thing are to find the 2 x 2400 watt power amps
I guess the recommended 2400watts are 4 Ohm (2 x 2269H i parallel = 4 Ohm), and I am considering 2 x the EMOTIVA XPR 1 mono-block

I just read this thread looking for SUB info in general. Most of it made my head hurt. I have no idea on all the tech stuff. One thing that I found interesting is JBLPro now offer a sub to compliment the M2. Im sure that all that means is there are SOME instances where a person may want that option?

Wow, that SUB 18 is awesome. Wonder how much they are?
