FS: (Critical Mass UL12) (DLS A3 Amp)
Hey everyone. I'm a member over at CA and DIY, and haven't had any luck getting rid of these last couple of items.
First, DLS A3
This amp is not only much more powerful, but superior to a JL 500 and at the same cost (at what were selling it for). The amp is actually brand new. Bought last month, but he is upgrading to a different DLS amp. Purchased authorized from Don (Pearl96Max). Original boxes and all.
RMS output per channel at 13,8 volts, 20 Hz - 20 kHz , < 0,1% distortion.
Mode : AB
Number of channels : 2
Output power in 4 ohm : 2 x 150 watt
Output power in 2 ohm : 2 x 270 Watt
Output power in 1 ohm : 2 x 425 Watt
Output power in 4 ohm bridge mode : 550 Watt
Output power in 2 ohm bridge mode : 870 Watt
Output power in 1 ohm bridge mode : 1200 watt
S / N ratio, A-weighted : > 100 dB
Damping factor : > 200
Input impedance : > 10 kohm
Input sensitivity, variable : 0,2 - 7 V
Filter, highpass, variable : 20 - 200 Hz
Filter lowpass, variable : 50-125 Hz
Terminal for external cooling fan : Yes
Double DC-inputs : Yes
Phase shift button : Yes
Current draw, idle : 1,1 A
Current draw, maximum : 140 A
Dimensions W x D x H : 410 x 240 x 73 mm (16,15 x 9,45 x 2,87 inch)
Asking $350.
Second, Critical Mass UL12.
This belonged to someone I work with, and really needs no introduction. He claimed to have had it for a year. It's 100% working as I have auditioned it myself, and the physical condition is very good. Motor is immaculate, the rubber surround is the only thing with a small scuff on it. It is in an enclosure, but if you want the enclosure it will be extra.
Subwoofer Size: 12”
RMS Power handling: 2500 Watts (undistorted power)
Peak Power handling: 5000 Watts
Recommended Box Volume: 1.2 cuft. (Sealed)
Weight: 16.6 lbs
Motor Type: Dual Gap / Internal NEO Magnet
Voice Coil Type: Ultra-High Temp Dual Coil (Made in the USA)
Voice Coil Diameter: 3”
Voice Coil Impedance: 1.5 ohm nominal per coil
Xmax (one-way linear excursion): 36 mm (3” peak-to-peak)
Maximum Excursion (one way): 46 mm (Almost 4” peak-to-peak)
Sensitivity: 96.7 db (2.83V / 1m) (coils in parallel)
Fs (Klipple-LSI): 31 Hz
Qts (Klipple-LSI): 0.81
Vas (Klipple-LSI): 47.7 Liters
Asking $750 + $50 Enclosure (If wanted)
I accept money orders, PayPal (buyer covers fees), and any type of
check (have to wait for it to clear).
I will listen to reasonable offers.
