Laying the TN1220 on its side

[Nigel_Pl]

Hey all,

I tried laying the TN1220 on its side so that the woofer is a couple of inches from the side of the couch and the port is a few inches from the side wall. All I can say is....mmmmmyyyyy gosh! The visceral impact from DVD movies especially explosions is far more lethal now than when the TN1220 was upright at the front corner. I recommend everyone with a TN sub to try it. I've managed to conceal the sub by placing a table over it so that the table legs are on each side of the the TN1220. I'll definately keep the sub here till my insides can no longer handle the bass waves!

My only concern is condensation building up inbetween the carpet and the TN cabinet. Can this cause the cabinet to warp like MDF exposed to moisture?

Thanks Nige

That's nearfield listening for you. Dr. Hsu's recommended method.

I put mine on some styrofoam blocks that has a stepped U-shape to cradle the sub between them. Then I temporarly put some lead shot bags on the port end to hold down that end. I think Sasha recommends something called silent foam so that they don't squeak when the subs shoot off. But I can't veryfiy that they don't absorb water and carry it up to the tubes itself in case of massive moisture (like flood).

Extreme moisture would weaken the sub while it is wet, but would not warp a tube.

Raising the tube off the ground with some foam (not styrofoam) would allow ventilation all around the tube (hence fast drying) for those who have wet basements or rooms.

Thanks guys

I assume as long as it is closed cell foam, so that they don't wick sewage water from the floor onto the tubes.

Nigel,

How is they layout of your room and the position of the sub? Just wondering how close it is to the listening seat.


I've also got my woofer facing very close to the side of the sofa (I don't sit near that part of the sofa, so no nearfield for me). Don't know if I need to put a large piece of granite/marble to reflect off the sound. When I play signal real loud on the sub, I could feel the fabric on the side of the sofa fluttering

Hi LWang,

Here is a layout of my room. The TN woofer is 10cm from the side of the couch and the port is 10cm from the side of the wall. I haven't felt any part of the sofa fluttering...just shaking violently! :)

[Lwang]

That would be the optimal sub placement. Corner loading and nearfield listening at the same time.

Also, I meant that the cover of the sofa is shaking pretty violently, maybe much of the bass is getting absorbed? Plus the person sitting in the position next to the sub always has something to say something about the bass (it could be good or bad, depending on whether the are into HT sound).

[Nigel_Pl]

So far everything sounds good with both HT and music but I will try sitting on the left of the couch and listen to how HT sounds from there. (No one except me listens to music properly).

If bass is getting absorbed by the couch I'd say its more of the upper bass than the lower bass which may or may not be a good thing in your setup.

One also feels the shaking quite a bit on the couch. So I don't know if much of the bass from the sub goes to shake that part of the couch.
