Re: Carver Platinum Mark IV

Hi, thanks for your resonses.

I'm asking $2500 for the whole setup and I'm afraid transport is a problem.

At this point I don't want to sell the ribbon seperately. If I remember I spent about 300 on it and had it refurbished for another 300, but I'd have to check on the latter.

Re: Carver Platinum Mark IV

word of advice, your price seams high. check prices on ebay to give you an idea of prices.

Re: Carver Platinum Mark IV

You may be right but there's a 1000+ worth of extras here. There nothing comparable on ebay.

Re: Carver Platinum Mark IV

Ok, I looked. Why do you have a pic of plastic bags in some sort of woven basket?

Anyway, $2500.00 is unrealistic even with the extra ribbon and you can't count the cost of the new woofers into the equation, just doesn't work that way. I'd say $1500.00 is more inline and even then may be on the high side.

Some tips for selling. Dust whatever it is you're selling. Take good pictures and show everything that you're offering. In your case, show the extra ribbon and show the DBX crossover.

For the record, I'm not interested in them.

Re: Carver Platinum Mark IV

Thanks for the advice.

FWIW I'm not particularily counting the cost of the woofers into the equation, just a selling point. The extra ribbon cost $600, the DBX $300, and the various things needed to complete the biamping gets me more that $1000.

This is all coming new to me as I had my Carvers from day one 17-18 years my C-2 pre-amp since 86 but am lost on the DBX and all this about moving up ribbons to 200hz to make them last longer stuff!!! Can some one PLEASE fill me in on this? Should I be doing this and what should I do? I bring it up after seeing these Platinum's for sale and it being done to them.

Re: Carver Platinum Mark IV

Well, I thought the ribbons in the Plats crossed over at 100Hz to the woofers. The Silvers and AL-IIIs crosssed at 150Hz, I believe (I know, for a fact for the AL-IIIs). Don't know what the originals crossed at. Anyway, I guess upping the crossover frequency with an active crossover like a DBX would take some strain off the ribbons, as the excursion at lower frequencies is greater, but that would leave a hole in your frequency response unless the internal passive crossovers were stripped out. If that's the case, then he needs to address the other issues with the response curve of the ribbon that were taken care of by the passive crossover.

Reply to Scarabeo.

As you're probably aware most high end speakers benefit from biamping. This requires an "active" crossover which splits the signal before the amp (and of course more amps are needed.) That's what the DBX does. Its a digital device. You can find recommendations for analog devices on this website.

Again on this website, you can find very strong recommendations to set the crossover frequency at 200 Hz and also to alter the frequency curve to offset a resonant peak at 7kHz. Allegedly Bob Carver himself agrees with the higher crossover frequency. This is relative easy to do with the DBX which gives one lots of options, and I believe, though others could correct me, that the analog crossovers do much the same thing.

Re: Carver Platinum Mark IV

I then presume the speakers have no internal crossover in them — correct?

Re: Carver Platinum Mark IV

With regard to biamped speakers, the internal Xover has been disconnected. A big part of the biamp effort is to bypass that Xover which, as I understand it, is inherently inferior because of the required that it handle real power.

Re: Carver Platinum Mark IV

The Clearview crossover crossed the ribbons to the woofers at 200 Hz (except for the last model, which uses the internal passive crossovers of the speaker — which I never understood, because they are different for different models of Amazings). The Clearview crossover also had all the little tweaks to deal with the ribbon non-linearity which, unless that dbx unit also has a parametric equalizer built into it, won't be handled.
