TSC 100 vs Polk PSW10 (or PSW 110)

The T100 could definitely benefit from a subsonic filter... it appears TSC did not build one into the amplifier which is why it struggles with the deep stuff.

One of my friends got one of these a couple years ago for his subwoofer with a similar issue, and it greatly improved his bass listening experience for movies.

$39 might seem a little steep, but if it lets you get another 6-10dB usable volume out of your T100 it would be well worth it.

There are also some parametric/graphic EQs out there with built-in high pass filters. I used to have a Furman EQ so that I could run a subsonic filter on my SVS CS-Ultra subs. It was adjustable all the way down to 10Hz which is why I bought that instead of something like the PFMOD.

Matt -- It's a $300 Sub now, for what it's worth.

I don't have an SPL to measure db's... but I don't exactly have this thing maxed out.

Again... flat volume/gain levels across the board. Maybe I should just unplug the sub so the port doesn't chuff. ;-)

At this point, I'm lowering the sub so much that I'm killing the low/medium, and even 'big' bass moments just to keep the sub from chuffing on the 'extremely big' moments.

I mean, I am supposed to be able to have the thing turned on, right?

JV --- thanks for that link! I just might invest in one of those.

Try plugging the port. You will lose output but you should also lose the port noise.

Another popular option is the eQ.2, which has a couple parametric EQ bands built in. If your receiver/preamp doesn't have room correction ability, you may find the parametric bands to be useful.

Thanks again JV. I think that first one is more in my price range (or else I would have spent $100 more on a sub! ;-)

Until I go that route, I did get a little brave and started tweaking the EQ settings in my Onkyo receiver.

Awhile back, someone suggested that I cut-off anything 30hz or lower, but when I did, I lost too much bass and it didn't effect the chuffing enough. I put that idea in the back of my mind, since I didn't like the results.

But last night, I had a genius idea (that's sarcasm --- can't believe I didn't do this earlier).

I lowered 25hz frequencies as much as I could (The closest to 30hz I could get in the Onkyo 605 EQ -- just like I tried before)... but this time, I bumped up all the other frequencies in the sub's range.

This allowed me to turn down the sub's levels a bit more, really cutting down on the <25hz freq's, while still keeping everything above that line relatively normal.

Short version is... Now my sub matches up well in volume to my other speakers, and has passed two major tests last night (Iron Giant and Dark Knight) with no chuffing.
