Here is an option for a crossover to use with the CF speakers.

http://www.ebay.com/itm/Paradigm-X-30-S ... 1578892496

The idea here would be to roll off the low frequency information from the main speaker and be instead sending those lows to a separate amp and speaker capable of the low end. So this would use the output of the preamp as it's input. Then you take the outputs of this unit to drive both the normal amp for the CF speakers, AND wire the low output to a separate amp and woofer arrangement. The idea being to unload the lows off of the CF speaker.

Many units available to do this crossover work. Just thought I'd point out an economical one that would work for this duty (or for Open Baffle augmentation use too).

Mark, have you looked at the MiniDSP? I know James used one at one point as well.

The 2x4 RCA would allow you to connect 2 subs for stereo as well as being able to custom tailor your response with filters, etc. Its basically a computer programmed crossover.

Oops...just saw this Dan. Yes, I'm familiar with the MiniDSP. I was just throwing up a simple and economical crossover for somebody/anybody thinking about this need for their situation.

The miniDSP is certainly a choice to be looked at for about anybody thinking of a crossover. Capable and economical.

Who Can Smoke a Carverfest speaker faster than Martin?

Post by radioeng2 » Thu Oct 08, 2015 7:11 pm

An option for those that want to up the game and plan right from the outset to come out at the top of the "Smok'em" game....

Who Can Smoke a Carverfest Speaker Faster Than Martin?

OK...we have on the table, if you can see it through the initial smoke in here, options that include a robust 6000 watt amp!

Now bouncing around for discussion is running many Carverfest speakers all at once. This comes with risk. How can you get so many to go up in smoke and flame all at once? High stakes to consider here if you want to walk away the winner. So here is an option if your in the camp considering running many pair at a time...

Look to an old favorite source for all your stereo gear...where else but SEARS!!

http://www.sears.com/pyle-audio-home-a- ... xECNMPOP19

Where else could you get a stereo amp with a 1,000 watts (thats a hundred thousand milli-watts folks!!) for only the very reasonable outlay of just $86.99 per amplifier. Now if you're planning on trying to smoke a dozen sets of speakers at a time, you may really, really want to do it with that 6,000 watt beauty, but by going with the Sears special, you also have the strong possiblity of adding the smoke and flame from the AMP to the smoke and flame from the speakers! WOW!!!

You are just going to have to think big for this compitition! Martin took the early lead and you can tell he's holding his plans close to the vest for the next go around, but yes...he's got some really big plans to really up his game. So you must too! Sears to the rescue....

Finally spent some time comparing the CF Speakers to my Plats. I am impressed. I listened to the same cuts on both. I have them sitting right next to the Plats but a little bit forward. The CF appear to play a little louder. I would turn off the amp and switch the speaker cables without adjusting the preamp. The volume appeared to be a little louder after switching the CF. I even listened to a couple of cuts using a Plat on the left and a CF on the right. As strange as this might be it was not immediately apparent that one of each was playing.

Bottom line..................I think they sound almost as good as my Plat Mark IV's. The CF soundstage is way wider. I have not even tried SH yet.

Ed - I found that for SH they need to be handled just like any other speakers, exhibiting the same old paradox: for SH, place them closer together for them to sound farther apart.
Best if the Plats aren't sitting there in such locations as to establish early reflections, which can interfere with the interfering signals from the SH.

Got mine finished finally and hooked them up to a 20WPC integrated tube amp first. They sounded a bit bright for some reason, maybe not enough power for the 4 mid drivers. Let them play for awhile and then switched over to the sunfire TG II as a pre and the 300 X 2 Sunfire amp. That made a world of difference. These speakers need good clean power to sound their best. I did play with the sonic holography and it sounded good. I need to experiment with placement a bit to find the best sound. The speakers are going through a break in period, and listening to them you can hear them changing as the drivers and caps break in. Have to say, I'm amazed at how low these speakers will go. I did not hook up the sub with them yet. I'm sure the sub will make them sound perfect! :D

I'm taking this set up to North Texas this weekend for a get together at Dskips. Wish I had the specs on them, because I know some of the guys will be wanting to know more about them. I looked through the speaker build threads and could not find any info on this. Anyone have the specs on these speakers?

I'm guessing specs would be very close to the Sunfire CRS-3c, same ribbon with four woofers.

From the Sunfire website:

Frequency Response 80Hz-40kHz
Power Handling 25-440W
Impedance 6ohm (nominal)
Sensitivity 90dB
SPL (max.) 117 dB
Oppo Sonica DAC
Sunfire TG-III
Sunfire 300x2
