I am about to receive my repaired Velodyne amp for a SPL1200r, a 12 inch sealed sub. I use it in as a 2nd sub w/my B460 which is ported. I will be running both off a SMS-1 in a home theater set up/also my 2 channel system. The people at Velodyne said it is a known that ideally not to run a ported and sealed sub together. Well, it isn't known to me so I wondering facts/opinions on how extreme an idea this is. I am sure it is not as bad as running 2 subs out of phase for example but is there more effect than ceramic wire stands across your floor? (I can't tell that different to those that can). The rest of the equipment in the set up(250TI and 120TI ) is ported.
And lastly there are a few configuration options that could be used. For example set up the b460 as a sub to only the 250 through a bx63 clone (Paradigm) so when to 2 channel full range and tap off that signal rather than the sub out and leave the Velodyne on the sub out. for HT work. Or any combo that can be done.
I will end up with what sounds best top me of course but welcome all opinions and facts and hope I can tell the difference if you post a reply
