@PeterPan:

so you changed the chassis to visaton?

Did you change the crossover, too? I don't know much about crossovers, but as far as I know, you have to modificate the crossover?

The visaton chassis should have a better quality, is the sound different from the ITT chassis?

@ Steve:

Do you still have the redline speakers? Did you compare the rl 140 with the Pentas?

@ Stereomensch

My speakers are from the start BeoVox Penta.

Has anyone of you ever tried the modifications of our member "die Bogener"?

I think he changed the crossover a bit?

Der Umbau ist der Hammer...

Hi BeoWorlders,

I'm glad to see this thread, I'm the happy owner of a pair of BeoVox Pentas that I bought 6 years ago, paired with a Rotel IcePower amplifier until .. 2 days ago. The Rotel RB1510 was a 2x60 W power amp and was already delivering - I thought -  beautiful sound to the Pentas. 

And then 2 days ago, a hi-fi dealer came to my place to make me try 2 other amps, a NAD2700 rated at 150 W and THX certified, and another esoteric amplifier from Vatiros (made in Thailand, huge mono blocks rated at 120 W).

After trying the Nad, then the Vatiros, I paid him for the Vatiros mono blocks and am rediscovering all my albums ! The dealer was with me when I played my test playlist and was looking for a sub all around the place.. I told him "there's no sub, just a DSP with room correction", much like what BeoLab 5 does.

My Pentas were renovated inside and outside: of course the midrange drivers were reconed, all drivers were silver-soldered to the internal wires, all filters were upgraded with new and better capacitors, and the black frets were replaced as well.

I'm using a DSPEAKER Anti-Mode DSP/room correction DAC that makes the Pentas go down to 35 Hz at -3 dB, and also removed their typical 100 Hz "bump".

The stellar prices on the new BeoLab speakers makes me want to keep them for as long as possible, not to mention the fact that they seem to have been designed to fit my windows..!

Would love to hear more about your DAC setup!

I second that, would love to hear more about the DSP and DAC setup!
