Hello, I have an black ep500v2 with the shiny silver woofer and an amp with x-over bypass. I also have 2 beech ep500v2 with matte silver woofers with amps and 150hz x-over.
1. Are the woofers the same except for the finish and is there a performance difference?
2. How come my 2 amps with the 150hz x-over still brickwalls at 100hz like my other one on bypass?
3. Are the amps internally the same except for the 150hz vs bypass markings?
I also have the earlier EP500 with the brick-wall filter at 100Hz. This is fine since I use an 80Hz crossover with my M22s. The 150Hz provision(yes, it's my understanding that this should be on all units in the past three years or so)would only be of significance if very small speakers requiring a crossover above 100Hz were in use.
Yes, the drivers should be the same and the amplifier as well. One change made in the amplifier was to slow down the rate at which the volume control "opened up", so that a higher setting was used for the same volume level. This didn't in any way indicate that it was less powerful, only that a higher setting resulted in the same power.
Yes, I have noticed that too about the gain control, the amp with the bypass would be at 6 o'clock, while the other 2 amps with the 150hz would be at 10 o'clock to be at the same spl. I've read somewhere that the powder coating used on the flat silver woofers reduces ringing vibrations, go figure.
Maybe the software for the 150hz amps were not updated cuz they still brickwall at 100hz. Shame cuz I was planning to feed them a full range stereo signal for stereo bass and cross them at 120hz.
Note that you're not likely to get actual "stereo bass" if you mean that you'd connect one front channel to each sub. Bass is nearly always mixed mono and is essentially the same in each main channel. Also, how would you "cross them" at 120Hz without a crossover.
Use the EP500's x-over while the mains play full range and the AVR on pure audio mode.
