wake up and can't wait to test on my setup

cdp -> coax -> AD1865 -> dcb1 -> SIT L'Amp -> PRV & T90a (0.68uF)

FullRange + Class A is trully heaven

Nice setup! I’m curious now and might try with my MOAMoFo soon!

Greetings to all,
Well the PRV 5MR450-ndy, but the PRV 6MR500-ndy ...
Can they be a substitute or are there too big differences? ... and what could they be?
Thanks, greetings to all.

with a tweeter - I think the 6 inch PRV could be pretty good

Thanks FREDDY!



very interesting the charts you have published, however your premise, of the need for a tweeter is for me the real core of the matter. I have read about the good things of the 5MR450, the fact that it behaves like a true full range on steroids, but it would be useful to understand if in practice even the 6MR500 has the same behavior, or if there is a big change of voice as it sometimes happens and needs of a tweeter in addition.
Unfortunately I cannot afford to buy the two models to make a direct match, I would ask if someone could make a practical comparison to report the differences and his impressions between the two, if possible.
Thank you and greetings.

The 6MR500 barely reaches 13kHz, and drops like a brick after that. Add in the beaming, and you'll feel that the highs drop pretty fast.

I'd stay with the 500 series if you want a one driver solution.

If you don't mind dealing with a tweeter and XO, then I'd probably get something that would deliver more bass authority (bigger cone) to match with the tweeter.

I saw that someone uses a pair of 5MR450s, I suppose to give more verve to the own lower band sound, but in this case the treble should be ruined ..... or the problem is not so serious?

You mean TransFi in Lencoheaven? He uses it to get 101dB sensitive (at 2.83v) tops for rock concert realistic levels with low distortion. I don't think the treble would be ruined - there is a slight vertical variation if you are closer than 6ft but not noticeable. I did this with dual TC9FD's in the Nautaloss and it sounded very nice - really brought out the dynamics by giving it more headroom.

HI X!
I thought of that case.
Thanks, I think I understand, so the reason is SPL .... I was doubtful about having more body, weight, consistency in the sound character and so I thought the 6MR was enough rather than the doubling of the 5MR, but it seems to me that 6 is to be excluded due to the accompanying acute deficit.
Thanks, greetings to all.
