DCM vs. MTX Sub
I'm having trouble deciding on which sub would be better. I love the MTX 15" sub with the passive radiator priced at 300 bucks. Also, I found a DCM 15" with a passive radiator for 270. Both have class D amps rated at 250w Is anyone familiar with DCM products? Would it be worth 30 bucks more for the MTX name? Here are the specs on both subs. Thanks for the help.
=MTX=
Amplifier Power – 250 watts
Frequency Response – 27Hz – 120Hz
Tuning – Passive Radiator
Input – High Line
Output – Line
Phase Switch - 0° / 180°
Level Control – Yes
Auto Turn-on – Yes
Delay Off – 10 min.
Low Pass Slope – 24dB
Subsonic Filter – 18dB@24Hz
=DCM=
Polarity switch: This two-position switch allows the best match of acoustic output between the subwoofer and the main stereo speakers in the region of the crossover frequency between them. The "normal" position maintains phase from input to output, the "reverse" position changes polarity or phase by 180 degrees.
Power switch: This three-position switch controls the power status of the subwoofer. Off: Turns the unit off. Auto: Places the unit in the standby mode, in this mode the subwoofer will automatically turn on when an audio signal is applied to either the high or low-level inputs. On: Turns the unit on regardless of whether a signal is present or not.
Subwoofer crossover: This rotary control adjusts a variable low pass filter to set the upper frequency at which the output of the subwoofer begins to roll-off. Continuously variable from 40 Hz to 120 Hz, it matches the upper frequency characteristics of the subwoofer to the low frequency response of the main stereo speakers.
Line level output: These RCA phono jacks provide a line level, stereo output of the full range signal input. This output is provided for those wishing to "biamplify" their main stereo speakers.
Line level input: These RCA phono jacks accept a line level full range signal from the preamplifier output of a receiver or preamplifier. This full range signal is processed and amplified to power the subwoofer.
Speaker level input: These terminals for speaker wire accept a stereo, speaker level, full range signal from a receiver or power amplifier. This signal is processed and amplified to power the subwoofer.
Fuse: For continued protection replace fuse with same type and size listed.
Level control: This rotary control adjusts the level of the subwoofer and is used to balance its volume with that of the main stereo speakers.
Status LED: This two-color light emitting diode shows the status of the subwoofer electronics. "Red" indicates that the amplifier is plugged in and the power switch is either off or in standby mode with no input signal present. "Green" indicates that the amplifier is operating with signal present at the input from the preamplifier, receiver, or power amplifier.
Amplifier Type: Class D – Amplifier technology that allows it to run up to 90% efficient
Amplifier Power: 250 Watts – Allows the subwoofer to be powered independently
Frequency response: 27-120Hz – This means the subwoofer plays to the bottom of the human hearing threshold
Inputs: Line level – RCA connection allowing versatile hook up to most receivers
Outputs: Line level – RCA connection permitting hook up to another amplifier
Hi-pass subsonic filter: 18dB@25Hz - Help protect woofer against harmful upper frequencies
Polarity switch: 0o/180o – Enables user to contour sound to room
Thanks again.
