pair of subs

[wessyb]

Hey guys, i recently repaired an infinity alpha 1200s subwoofer which works pretty well. my question is this; i am picking up my pb-nsd10 sub tomo and wondered if its a good idea to use both subs or should i get rid of the infinity? Will they make a big difference?
How do i pair them? do i place one on top of the other or do i use different positions?

If you use two subs, you should use identical subs.

Ok thanks very much

Warpdrv, a member here, has mentioned how pleased he's been with his dual-sub set-up, and they aren't identical subs. Perhaps he'll chime in on this one? There's been a number of discussions about setting up two subs on this site, so you might want to search the forum for that topic.

If you use two subs, you should use identical subs.

If you have it in a stereo or off balance configuration (opposing corners).

I used to run the weaker sub in my system behind my seat, with my louder one on my front wall. Worked well for me.

Two will always be better then one. It will fill more seats with bass.

That's how i thought of it sheep. i will still search for the topic anyway.

That's not always true.

i will have to agree with this one, especially if there's no way to check the frequency response. (you can use Room EQ Wizard to experiment duals, placement of each, etc.)

That's not always true.

Have you ever tried 2 different subs set up properly?

Matching subs can be designed with some good ingenuity and planning to produce solid wall of sound with equal pressure over the seating area or areas with pressing authority.

18” subs are the best a few good ole cinema PA types are the preferred choice.

i think i agree that both subs do not have to be identical. both subs together could add to the total bass output which would fill a room more than one. What i do believe, now that i have thought about it, is that both subs should be of similar output or depth.

Try it out in your system. I had a 10inch Athena paired with a 12inch Velodyne. Sounded great for movies. Didn't need the extra bass for music. Just having another sub in a different spot (not just any spot, however) will have with filling out seats in your theater. I have 6 seats to fill, and having 1 sub in 1 corner, and the other in an opposing corner made a HUGE difference.

I have two identical subs on front wall, one right, one left. Works very well. But i've been reading with interest about STACKING subs in one corner. Has anyone tried this method with any success? The subs are heavy, and i'd be worried about marring the finish of the bottom sub.

Six seats LOL, go to the EMPIRE that’s got more a than six seats and the original JBL spec had x8 JBL 4645 18” subs that knocked me back in the rocker, hell knows what x16 matching JBL 4645C subs would do when I pop up there soon for DIE HARD!

Matching subs everyone there’s no dispute if you haven’t got the money save up until you have enough to buy a second and third and fourth and fifth excreta, excreta. Thou one seems idea I would like to lay my hands on another JBL 4645 loaded with a ribbon cloth edge surround sub bass driver, no foam!

Does anybody know of a piece of equimpment that could block out some of the lower bass frequencys from a Sub. I am looking at several different Subs currently, but was thinking of trying to run my current SVS PB12ISD, as a mid bass setup, similar to the HSU piece. Then letting my yet undecided new sub, handle all the nasty stuff.

With a parametric EQ you could theoretically turn off certain frequencies from the sub so it only plays the frequencies of your choice. I am pretty sure thats possible at least.

To do this correctly, you need a specialized piece of gear with flexible assignments/parameters. A Behringer DCX2496 would do what you require.

But since the PB12ISD was not designed for strictly midbass like the Hsu, I not exactly sure what you would gain in this scenario other than nearfield placement.

The Hsu MB-12 was specifically designed for this duty, so you get higher output/headroom in that specific range, as well as a cone that is lighter for better articulation and response.

you can also buy a subsonic filter (it looks like an RCA interconnect) from harrison labs? harris labs? (search my posts for the right name)

or you can buy a similar unit from HSU - they have a bass management thingy ..

while silversurfer is correct that a dedicated mbm will do a better job, nothing beats free right? since you already have the sub, go for it!

Thanks for the replies, and sorry to hijack the thread, but after doing some playing around with placement, I found that I actually liked my current location of my sub than in the corner next to my Sofa. And since you are supposed to install the HSU MB12 next to your seating location I don't think I would like it. When I moved my current sub closer to my Sofa, it did not sound right, even after making adjustments. Don't know if I will make it through the weekend before making the Call to SVS for the preorder of the PB13 Ultra, and just selling my old PB12ISD. I think the wife would kill me I I moved it into the bedroom.
