Need sub recommendations for vr4 jr's

OK. . . Drew... I'll do the shot thing ASAP. it was already on the list... in my area, (and it sure came as a suprise to me), the shot provider is a trap & skeet club that only opens on Wednesday, and Saturdays. Getting a ride out there is mostly the issue... I had planned to do it for my Xmas present to me... but was waiting till I got the speakers right where I felt they did their best... lots easier to move around a 45 lb. cabinet than a 95lb. one.... right? so it's just a matter of time... I think I'm pretty close to where I need to be in placement, though I'd like to try a couple more moves... mere inches makes a good bit of difference... and not being able to see it all taht well slows down things a good bit... but it'll happen soon enough...

One thing, the shot only affects tone of the bass, right? No re-positioning required, right? I mean the bass toneal change is just a somewhat tighttening of the bass tone, right? and I got a hallway on the left side that needs closing off by adding a door (s), too. so I'll flip a coin to see who's first... the open hallway lessens the left channel impact unless in the nearfield... or sit a bit off to that side otherwise. (I thought for the longeest time something was wrong with the gear... nope. Just the opening in that wall.... Amazing! Huh?)

Update: I've been trading emails with VSA concerning my REL sub. They have convinced me that if properly setup the REL can / will be benificial. I haven't moved it from it's old "dialed in" position when using my old speakers, but did turn down the crossover and I'm enjoying it enough that I pulled it off the for sale listings. I listen to mainly Rock and Roll and the additional bass is a nice touch. If you haven't already talked to the guys at VSA you should, eveyone I have dealt with has been very helpful and there's nothing like getting advice from the manufacturer.

I have spoken with VSA... Albert V, too. about placement and room treatments... Kevin as well, as to placements and subs... Sometimes they are not the most timely responses... but yes, they are very helpful. I get the impression from them as well as other, though, that subs are a matter of prefference like genres of music... significantly seems the crossover, range and harmonic presentation... I'm about certain I can add most anything to replace the one I have and do OK. It's old. and small. and not too powerful. But given the price to upgrade to another unit, I'd like range - cosmetics - and flexibility in both control and interfaces. The ACI titan, and the Revel 15 both have that... now it's price. I can hear the Revel locally and I will soon... but everything is on hold for me for the next couple three months or so... Taxes insurance... etc. So now is 'research' time. Hearing what others have done or are doing is valuable... and I am most apprcieative. Thanks.
