Strongly echoing MLA's Kicker KM654 suggestion.
Stay clear of W-domes in entry level coaxials. They just sound nasty. Go with a true dome.
The Polk dB is really a decent sounding speaker....but it...

AC volts squared divided by impedance = wattage. You need a 50 Hz sine wave tone for a subwoofer channel (CD or download) and a multimeter to measure the AC voltage. The speakers/subwoofer must be...

The Syn-DX6 is definitely adequate. But with the SD6 the entire system does get better. Although there is no real benefit to 585 watts for that sub. I have run that 10" IB sub with 340 watts (@ 14.4V...

The Syn4 is a very good amplifier. However, the four Icon8s are getting a maximum of 125 watts each @ a 14.4V supply and less with a more realistic supply voltage. So I don't think you have heard the...

I can't assure you that you would be making the right move. I think the Wetsounds Icon8 has pretty good midbass for an 8-inch tower speaker and that two pair would be getting the job done. From...

I like contributing if and when I have something to offer. While there are so many members who also contribute, I especially enjoy reading those contributions by Jim N and MLA. Great assets IMO.

That appears to be a lowpass-only filter. Your best bet is to run it up to 300 Hz., it's highest setting in order to defeat it the best you can. Then use the LP filter on the amplifier.

I really have no clue.
If the M400/4 is using the CL-RLC pass-thru, perhaps this output is buffered and still has some impact.
