Alright, Ive got my old two tubatrons still sitting in my closet, I have some down time due to a blown PJ bulb (second one in a year, grrr, has nothing to do with the subs I promise!). Im going to pull my screen and really do some cleaning up behind it. While im at it, I am going to reincorporate the LLT's which are two tempest x-2 15's tuned to around 11-12hz powered by an epx4000 to my already existing dual XXX 18's that are on the fp14k.
I have the DCX 2496 still in the chain to eq, and ive got a 4311 and an sms-1 on order, but the different options im considering and would love your input on is:
1) keep the LLT's as they are, let them AND the XXX's play all the same bandwidth.
2) cut down the tubes a good amount and raise the tuning to aim for MEGA midbass output to help up where the XXX's get inefficient. EQ them seperately where the XXX's maybe run up to 40-50hz and the tempests go from there to maybe 120hz optimally. These would still be ported.
3) Remove the port from one tube, cut it down some and create a single dual opposed sealed setup for the tempests, and either eq them seperately or together???
As far as placement goes, none of these options would grant me the ability to put them anywhere else in the room other than behind the screen, but the final option, just building a quick sealed box or two and scrapping/selling the tubatrons is also a consideration. With the sonotubes being 24" dia, I couldnt even make these end tables or anything, just too big around... but what I could do, with the sealed boxes, is put one beside each row of seating.
Im not really looking at making this TOO permanent, as I still want to put two more XXX 18's in, and in the not so distant future if I am able to, but i thought one of these options would help me out during the interim. My overall objective? Well, more displacement, for help down low, but also to help the XXX's up where they become less efficient. can I get both with one of these? Perhaps if I left the LLT's alone, but making them blend with the sealed XXX's might not do well.
Id love to hear your thoughts guys! I saw the other post regarding something similar, but as I havent decided to split the bandwidth or not yet, this digs a little deeper
