Which 18? (2269H, Aurasound, Revel or TC Sounds)

[johanwholst]

Where does JBL recommend cross M2 to Sub18?

[baldrick]

How deep is the 2269h (preferably in centimeters)?

I was going to try them With my 4645b cabinets, but they were too deep.

Compared to 2258:

Congrats! I was too lazy for DIY, so pulled the trigger on two SUB18's.

I would have done the same except of the price. I don't think the cabinet alone is worth 3 times the price of 2269h, it really is a lot of Money, excepially With 4 of them But I might use the cabinetdimensions of sub18 but do consider a lower tuning than sub 18.

Thanks for the pic.
Can you please measure it for me, how deep it is (approx)?

I agree that the cabinet is not worth the price... But it made more sense to me in the given situation.

I am going to integrate them with the M2's (LCR) and cross over at 80hz. I have not seen any best practices from JBL regarding integration/crossover, but I follow the guidelines of ARCOS and their general configuration of Synthesis theaters. K2 S9900, Everest and all their other speakers are cross at 80hz to the S1S-EX's. I haven't heard that they would change this approach with the M2s.

Which acoustical crossover slope? linkwitz-riley 24dB/oct?

Hi,
Interesting question, highly advertised M2, as STUDIO monitor too, with bass extension....???????? interesting result.

It's alive

Slight modification to the 4645b boxes and it slipped in...

First impression is quite good, quite a bit more output in the lower region than 2242/2258 what I was looking for, BUT still not the VLF that I really was hopeing for even though the Box now is tuned to aprox 18hz. I might need bigger cabinets or maybe other woofers with lower FS

Maybe electronic compensation? This sub doesn't bother if you have the needed power amp... or add mass to the cone...

Are you kidding? I'd pay the price just for those beefy looking flared ports!

You'll need some electronic boost down there. Had you tune to Fb 28Hz, you would have felt more VLF as tuning a cabinet too low reduces the bottom end of the response. perhaps you can do a simulation.

Cabinet is org tuned to 25 hz, now it's 18hz just to test it out. I've also tried boosting up With DSP but it doesn't give the result I was hopeing for.

What I compare too is my previous TC Sounds LMS 5400 which gave a lot more VLF than this do at the moment.

Simulations shows that it should work quite well but not 100% satsified right now.

What do you think of putting 2269 in a tapped horn?? I've no experince With this kind of Box but it might be fun... someone know how to simulate TH?

[pos]

Does the sub18 come with specific DSP settings?
That would be a good start, after replicating the tuning and volume.
