Wont that give rise to phase anomalies when sub amp is turned on?
 
When you use reflex boxes that are tuned nearly the same, such issues are not a problem. Of course, from a chart standpoint, the phase response are not identical amongst the two. However, if your ears cannot detect it, you are merely chasing something based on a visual perspective and, not letting your ears be the deciding factor.

I forgot to add...

Low Mids: 500 Hz (-3dB) to 35 Hz (-3dB) 

Despite I use the K30 for Low Mids, the amplifier is being fed bass frequencies well within the range of many who tune their subs to (for example 100 Hz - 35 Hz).

Low Mids on JBLs as JBL offers a lot of "warmth" on their own. The EV (15's) don't offer a lot of warmth so they stay on the QSC (playing low mids as well).

Anyway its been some time since you tested the K30, hows it holding up?
Any faults, problems yet? Im asking because im considering buying one
Thanks in advance!

Zero issues as it is approaching two years in service. 

Here is the review:


Popularity seems to be minimum in Europe, in comparison to the United States and, the Caribbean.

Nice.

Made one as well a few years ago however, offered the rail voltage. More revealing when you add the dB differential in the equation. Would need to search my drives to locate if interested.

hi, not sure if you'll find it useful, but i made a spreadsheet for the paraflex group on fb listing all the chinese amps out there - thought it would be handy for comparison.

never got round to finishing it but here it is anyway

In the end, the amps proved to be very reliable and the modules are still unused, but I would never had bought unless the modules were available. Better safe than sorry.  Smile



Which heavy weights did you buy ?



These:-

And a couple of the "lighter" EX-1000:-

I sold most on, but still have 2 of the 3400's working regularly. Definitely a solidly built amp.













CA18 transformer??






Spare module:-  Smile
