No bass from the subwoofer - Atlantic Tech T70PBM

Older Atlantic Technology T70 PBM subwoofer, part of a full 5.1 system.
getting no bass from the powered sub. speakers set to SMALL so sub should work, crossover set to 150hz like it's supposed to, getting power, not in standby mode, cable is properly connected. (can a sub cable go bad?) is there a fuse in this sub? when I run through the setup on the receiver, I either can nothing from the sub or the signal comes out of the left front surround speaker.

Try filling the inside of the enclosure with insulation [roof insulation will work ] or a small pillow just to see if its the box or the driver rattling if its the driver you might have to secure it to the enclosure with screws or something ,

I'm trying to connect a small bass speaker to a Sony micro system


There is no place in the picture that would connect a bass speaker to your system. The outputs are for full range speakers so a sub will never work on this system

Splicing headphone outputs designed for nominal 8-ohm impedance speakers to a 47K-ohm (typical) RCA load is not a good idea but it might work on the Sherwood because this receiver does not automatically silence your other speakers when the headphone jack is installed.

There is NO other volume-controlled output to choose. Try it.

Can we use the subwoofer as an amplifier for speakers? it has jacks for speaker in/out, but i can't figure out how to make it work because the speakers have no sound.


I don't believe this hookup is amplified; but, if you have used the regular unfiltered speaker connections from your receiver/amplifier to hookup the subwoofer, the system will pass the signal thru the outputs subject to the crossover adjustment on the back panel. You cannot get the full signal if your system is sending only the bass signal to the subwoofer. I have copied the instructions below from the manual. You would set the high freq crossover to the low end of your satellite's frequency range. The full manual is here: http://www.jbl.com/EN-US/Products/Pages/ProductSupportDetails.aspx?PID=PSW-D110

High-Pass Control
• If you hooked up your subwoofer
as shown in Hookup
3 on page 4, you also have
the capability of adjusting
the high-pass frequency.
The High-Pass control
determines the frequency at
which the main speakers
will start reproducing
sounds. If your main speakers
can comfortably reproduce
some low-frequency
sounds, also set this control
to a lower frequency
setting, between 50Hz –
100Hz. This will concentrate
the subwoofer’s
efforts to the ultradeep
bass sounds, while your
main speakers continue to
reproduce the mid-bass
information. If you are
using smaller bookshelf
speakers that do not extend
to the lower bass frequencies,
set the high-pass crossover
control to a higher setting,
between 125Hz – 180Hz.
With this setting, your main
speakers will not have the
burden of reproducing any
low-frequency sounds.
• If you hooked up your subwoofer
as shown in Hookup
1 on page 3, the high-pass
frequency is fixed at 180Hz.
• If you hooked up your subwoofer
as shown in Hookup
2 on page 4, there is no
high-pass control. Unless
your receiver/amplifier
incorporates a high-pass
crossover, your main speakers
will continue to get a
full-range signal.
Final adjustment and blending
of the low-pass and high-pass
controls may evolve over several
listening sessions. A good
starting point would be to set
both the low- and high-pass
controls to the same frequency
and adjust from that point.

Have this Bose system connected to my Yamaha a/v receiver


If you have it literally conencted the way you say not much good will happen.

The speaker OUTPUTs for the Yamaha feed the INPUTS on the Acoustimass Module then the satellites branch out of the Acoustimass Module's OUTPUTs.

Acoustimass module
Bose® recommends putting your Acoustimass module at the same end of the room as the
television monitor. To prevent interference, keep the module at least 2 feet (.6 m) from the
television.
• You may hide the Acoustimass module behind or under furniture, but do not block the
opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
corner.
• Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the
cable connection end, remove the cover by gently pulling it away

Move the sub closer to a wall or corner to increase the bass.

This is a SYSTEM and as such is not designed to be pieced out or separated. I don't recommend that you try it that way. I doubt it will improve the sound.

Not good surround sound Is the bose lifestyle 5 support 5.1 surround sound?


The Bose Lifestyle 5 is not a 5.1 surround sound system. It is a 2.1 sound system, meaning it is stereo with a subwoofer/bass unit. Having two speakers that can be angled in different directions, the Bose Lifestyle 5 employs Bose direct/reflecting technology,providing greater audio presence. Still, it is definitely not a surround sound system.

Home Theater Subwoofer rattles


Sounds like the controls have a buildup of dust on them and creating a magnetic charge and thus noise. Radio Shack sells "Tuner wash" Use it sparingly, it only takes a little, then work the controls back and forth for a few seconds and turn back on. You may have to do this a couple times to fully clean the potentiometer (vol control) (crossover control) Take the knobs off the unit before you spray it. If you have a high gloss finish on the sub, put a rag around the control to keep excess wash off the plastic. It will varnish a gloss finish. Just use it carefully. Hope this helps
