A common misconception is that subwoofers are loud, boomy thump
machines that simply make a lot of noise in dramatic movie action
scenes, or shake your insides with the very loud beat emanating from
the car next to you at the lights, or to add some boxy upper bass to a
tiny tinny sounding mass market satellite system --nothing should be
further from the truth.
A true subwoofer faithfully extends the music/sound on your CD, DVD,
Blue Ray, etc. to the frequency region below the reach of your normal
speakers (or the crossover point set on your home theatre amplifier).
It should simply continue the bass down, and down, without being too
loud, intrusive, slow, uneven in response, coloured or boomy. A good
subwoofer is musical, accurate, has a fast response and is uncoloured in a well built inert cabinet;
it enhances the realism of your music/movie, and your listening
pleasure, and does not stand out like a throbbing sore thumb!
Here is a range of models that have been carefully designed with
musicality and affordability in mind. The 1230PTL, 1030RTTL and 1025STL
are for small to medium room systems; the 1232PTL, 1225STL, 21030PTL, and
1550DTL are for medium to large room systems; or you
could use two smaller subwoofers. All models have unique hybrid Transmission Line
bass-loading channels like most of our floorstanding speakers and are
musical, accurate, controlled, and perform beautifully and
delicately at low volume levels as well.
Remember, the power of a subwoofer should be two
to three times the power of one channel of your main HT
amplifier. For instance, the 1025 subwoofer would suit amplifiers
around 100 wrms per channel; or a more powerful amplifier used only to
levels up to and around 100 watts per channel. The 1030, 1230, 1225,
and 21030 suit amplifiers up to 125 watts per channel, and the 21050,
1550, and IB1550 suit amplifiers up to 200 wrms per channel. Other
factors like the size of the room and the size of the other speakers
in the system can also have a bearing on the best choice of subwoofer.
A larger room needs a larger subwoofer, or two, and a small but powerful
satellite system also requires a larger subwoofer to take over a
greater proportion of the low bass bass smaller speakers can't do.
Any subwoofer can be ordered as a passive subwoofer for less cost, without a
built in plate amplifier, for customers who have their own outboard
subwoofer amplification and control.
All speakers include removable grilles but any speaker can be made without grilles and grille clips if you request.
