I don't get enough slam from my RT-12d

[thecutter]

I have a Ht set-up with RF-63's, RC-64 anf RS-62. I have a RT-12D. I have the LFP off. I set the X-over for my mains at 60HZ, center 60 Hz and rears at 80Hz.

I ran room correction. Phase at 0 degress.

I was looking to get more slam.. I was thinking of adding a SVS 13PB ultra or HSU uls-15.

Would this work? How do I set it up? I use an Integra DHC 9.9 preamp.

If by saying slam, you mean shake the wall deep bass, then adding a svs would do that.

I had the opposite problem of yours.

I have a dual 12 svs sub which was producing plenty of lows, but not enough mid bass. I just recently added a rt-10d, and it really helped. Still not as punchy as I was hoping for but much more balanced. So if it’s lows you want, svs will do that. I don’t know anything about nor have I listened to the hsu.

As far as set-up, all I can tell you is what I did. Connected rt to receiver, svs to the rt, then ran the auto calibration on the rt.

Unless the integra supports dual subs, I think you would just set preamp as if you had a single sub. Not sure about integra’s, but that’s how my receiver works.

Are your mains set to large or small? If they're set to large, try setting them to small. Also, what do you have your sub x'd over at?

[thecutter]

MY mains are set at small. X-over is 60 Hz.

TYhe sub is X'd at 80Hz. It won't play anything above that to avoid compression.

Dont listen to the SVS pushers,Many are just trolls on here,There are plenty of subs on the market that kill ,and whip the svs subs up side down.Now if we know what you want to spend that would help.I have heard plenty of svs subs that people purchased and got sucked in to buying one or 2,and ended up selling them off cheap.I tried out a few including the ultra and double fart box and thought they were a big joke! Now the klipsch rts are nice subs,But they need a little work setting up.

I have always associated slam with the upper bass frequencies....like 50Hz to 100Hz, and in this range Klipsch simply dominates.

For
what it's worth, the room will play the largest factor in the perceived
bass performance, especially in the upper bass frequencies where room
modes have the most effect. I would start with everything set flat
(turn off the room correction) and go with an 80Hz xover. Set the mains
and all the other speakers to small.

After you set the balance
so that everything is the same volume, play some bass heavy music and
walk around the room and note how different the bass
sounds....especially in the corners of the room.

What you want to
do is find a position for the subwoofer such that you get the most even
response at the listening position. Aesthetics usually dictates only a
few positions so it's probably best to just find which one works the
best. Moving the listening position might also be something to consider
(if it's feasible). As little as 1-3 feet can make quite a dramatic
difference.

Anyways, once you find the best position for the sub
and the listening postion you can rerun all the room correction stuff.
Note that changing the mic location will have an effect on the room
correction it applies.

Btw, I mention the above because getting a
new subwoofer will not change the acoustics of the room and it would be
a shame to invest in something with marginal gain when really the
problem is elsewhere and can be solved for free. I'm also assuming your
definition of slam is the same as mine....if you've got test tones on
hand, I think you might be surprised just how low 30Hz sounds let alone
20Hz...of course it needs to be low distortion when you're doing this -
otherwise you'll be hearing the harmonic distortion.

One last comment....because you're worried about slam, you might
also consider moving the main speakers around too. You also need to
make sure you get the crossover phase correct. This should be done
after you find the right placement for everything. I wrote up an
article that covers this since it comes up so often:

Dial in a Subwoofer by Ear

If you've got measurement capability, then this becomes a whole heck of a lot easier to do.

Wasn’t "pushing" or recommending svs.

Issue sounded similar to problem I just went thru, thought I’d share my experience since suggestions from forum members helped me.

Bought my svs 5 or 6 years ago and didn’t have any problems until I changed from towers to the ultra2's. svs provides plenty of lows, was just lacking mid-upper bass with new speakers. Moving the sub around the room wasn’t an option. I added a rt-10d, and it really helped, much more balanced sound. Maybe I mis-understood what you meant by "slam".

I’d just ask DrWho for advice. Clearly he know’s what he’s talking about. Good luck

I cannot believe you aren't getting enough slam from your setup. Somethign isn't right somewhere. Where is the sub located? What size/dimensions are the room? Got any pics? 95% of issues with "it doesn't sound like I thought it would" are due to improper speaker setup. We need more info to give you informed opinions.

TYhe sub is X'd at 80Hz. It won't play anything above that to avoid compression.

What do you mean by this? You have the sub's own low-pass set to 80Hz?

[jimmerz]

I don't mean to hijack your thread...but I have a pretty simple Klipsch in wall/ceiling set up. I have the RW-12D Sub and I am using a fairly junky 100w Panasonic 5 disc DVD plaer/HT receiver to power them.

My problem is I feel like I get too much bass from my sub, almost liek it is over kill. I've tried adjusting numerous settings, and it sounds pretty good just not exactly what I am looking for.

I have been looking to upgrade my HT receiver to an Onkyo TX-SR606, would this help things sound better?

Thanks.

Have you tried the volume control on the subwoofer?

What
you're probably experiencing is the great difficulty in getting the
sound from a subwoofer to blend in with the sounds of your in-walls. A
better receiver will probably improve the clarity of the in-walls a bit
and also offer more settings for getting the sound to gel.

Maybe
if you started a thread with a diagram of your room layout and detail
what youv'e tried thus far, you might be able to get some ideas you
haven't tried yet.
