Maybe a little more simple, and smaller version.


I'm guessing that other baffle design is the DBII and this is the original DB. Ive just been researching pictures on the forum.

id say build 2 seperate dbs exactly like plans and run em like that, mixing / blending output like you have in the drawing might not be a good thing? good in a wo, maybe maybe not good in the db? i have run 2 x dbs in a trunk. sweet.

Would you not have a phase issue(iso-loaded DBs) with running speakers in phase in different chambers? I have tried two DBs(iso-loaded) with the sealed chamber connected to each other. I took the baffle(cut out attached to the lid) and used it to couple the DBs together. It sounded pretty good but phasing seem to be a problem,I think ???. I did not have enough time to finish the test before someone want to hear them separately. The reason I think phasing is an issue is that the DBs hooked together were easier to overdrive with less power than if you were running them separate. With the DBs hooked together also caused excessive heat from the amp. The only data I have to go by is comparing them run separate and then bolting them together, so more test need to be run. If anyone has any luck with this combo I would like to know as much info as possible and the different ways you could test this set up. Thanks.  HT-EXT

Well, you could esily throw the ends into phase with eachother.  That way the output from the port is in phase from both of the subs on the ends.  With that much air being able to move in and out, the subs could easily push against each other and not experience any problems, where running them in the same sealed chamber out of phase would make it a very difficult task for the Drivers.

I other words:

thats a toughy there.

Normal Ported boxes have a considerable delay, however, the Db is just a normal box, since it is tuneable.

I would say you would have to measure the delay with a computer or other device.

In short, yes there is a delay. I wouldn't expect it to be more than the WO though.
