sredmyer Posted February 18, 2006 Share Posted February 18, 2006 DeanG if you happen to see this post could you please respond. I was refered to this forum by cecaa850 on another forum when I mentioned that my RF-7's were somewhat harsh. cecaa850 said that DeanG instructed him to add a resistor to the xover board on his RF-7s. I was hoping to find more information on this mod. Thanks, Steve Quote Link to comment Share on other sites More sharing options...
Speedball Posted February 18, 2006 Share Posted February 18, 2006 Hi Steve, I came here looking for the same thing a long time ago and to me the results of his work is outstanding. He seems pretty busy so don't get frustrated if he does not get right back with you.......Good Luck. dgwescott@sbcglobal.net Quote Link to comment Share on other sites More sharing options...
Fish Posted February 18, 2006 Share Posted February 18, 2006 Steve,while Deans xovers have a great rep and are highly recomended if you don't have the proper equipment to go w/7's you don't how they sound.I've heard my 7's sound ok/good and great,all due the prepro.If you've already done the footwork and auditioned many units on the 7's and have arrived at the very best you could find/afford,then Dean is the next step.

sredmyer Posted February 18, 2006 Author Share Posted February 18, 2006 My RF-7s are only part of my HT system. The reciever is an Harman Kardon AVR7300. For the front 2 (my RF-7s) I have an additional amp (an Adcom GFA 555) which was added because the primary use of my system is for 2 ch. music listening and I wanted more power. Overall I am quite pleased with how my system sounds however, I believe that at high volumes the high frequencies are somewhat harsh. When I made this comment on another forum I was told, by a member of this forum, that DeanG had suggested, to him, that he add a resistor to the xover. This individual continued to say the mod was simple and made his speakers sound much better. Steve Quote Link to comment Share on other sites More sharing options...
Deang Posted February 19, 2006 Share Posted February 19, 2006 Some of that harshness is coming from your old Adcom. I know -- I'm very familiar with the sound of that amp. To bring that horn down a bit tack a 10 ohm resistor in parallel with the 2 ohm resistor located on the first board. When you pull the network out, turn it so the wires are facing you -- the resistor is on the left edge of the board next to the large black capacitor.

GregB Posted December 5, 2006 Share Posted December 5, 2006 Dean - Do you know if the same or a similar mod can help Heresy III's? - GregB Quote Link to comment Share on other sites More sharing options...
Deang Posted December 5, 2006 Share Posted December 5, 2006 Apples and oranges. Different speaker and different network. If they were mine I'd rip out the mylar capacitors and drop some Auricaps in them. Still, when I heard the H III in Indy a couple of years ago I thought it sounded damn good. Of course, they had it hooked up to some damn good stuff! The RF-7 doesn't just sound hot on top, but measures hot on top -- find the Sound and Vision review.

Dylanl Posted December 5, 2006 Share Posted December 5, 2006 Get rid of them #1. Earplugs choice number #2[] I owned them and they are very amp non tollarent. Once I bought a Marantz they smoothed out nicely. Xover would be the last consideration. Quote Link to comment Share on other sites More sharing options...
Speedball Posted December 5, 2006 Share Posted December 5, 2006 Get rid of them? Mmmmmmm, I dont know about that...[:|] If Klipsch went to all the trouble of creating these things there must be some type of amp and preamp that makes them sing.........What is it?

Jay481985 Posted December 5, 2006 Share Posted December 5, 2006 something that can handle down to 2 ohms? I heard the qsc amps sound great but they are pro amps Quote Link to comment Share on other sites More sharing options...
Arky Posted December 5, 2006 Share Posted December 5, 2006 something that can handle down to 2 ohms? I heard the qsc amps sound great but they are pro amps QSC sounds wonderful...and Dean's network. Quote Link to comment Share on other sites More sharing options...
rsp1068 Posted December 6, 2006 Share Posted December 6, 2006 Rotel's RB 1080 handles them nicely, as does the VTL ST150. The 1080 can be had used for the 6-700 mark on agon. Quote Link to comment Share on other sites More sharing options...
GregB Posted December 6, 2006 Share Posted December 6, 2006 Dean - Thank you for your reply. I changed speaker wire from the Home Depot solid core to Radio Shack 16ga zip cord and stripped the end of the wire to run through both sets to binding posts. Helped get rid of some of the oddness I was hearing up top which I now attribute to the supplied link thingies. I think they roll off the treble in a way that can make some sounds seem unatural. At any rate, the speakers are not *horribly* messy up top - just too brutal and possibly accentuating faults that are there. This does make them a tad difficult to live with in a domestic setup with less-than-stellar (TV signal, iPod, etc.) sources. Others - were your comments about the RF-7's or the Heresy IIIs? - Greg <-who thinks the Heresy IIIs are *almost* perfect - just gotta smooth out the top a bit Quote Link to comment Share on other sites More sharing options...
Fish Posted December 6, 2006 Share Posted December 6, 2006 I must like it hot on top,I've always bumped the treble until I got 7's.I just noticed someone that complained of harsh highs was running an Adcom 555,no surprise,this amp is known(to me for sure) to be slightly harsh.I'm not knockin' it,I like Adcom but that amp is better used with softer speakers.Almost every time I see an rf7 harsh issue when I see the gear used I think,no surprise.These speakers are not plug and play,they need to be paired with gear that suits your ears and plenty power.I have never heard two different components sound the same on 7's.They cannot produce beautiful highs on substandard media,Zepp 1 ain't gonna sound like Steely Dan Aja and an ipod ain't gonna sound like an sacd.

Dylanl Posted December 6, 2006 Share Posted December 6, 2006 When I ran mine on a low grade Yamaha at 1st they were unlistenable. Listening to them throught my Scott 233 tube amp they sounded fantastic. Its all in what you drive them with. I always thought that they would be best suited for a Biamp setup. Power for the bass and tubes for the horns. Anyway I sold them for a pair of Khorns that I found for 1,000. Since then I never looked back. In there defense they were very good HT speakers straight out of the box. I impressed many a guest with my RF7's. Quote Link to comment Share on other sites More sharing options...
Arky Posted December 6, 2006 Share Posted December 6, 2006 something that can handle down to 2 ohms? I heard the qsc amps sound great but they are pro amps QSC sounds wonderful...and Dean's network. My comment speaks to the rf-7. I've never heard H3's. Dean's reworked network is worth every penny. Quote Link to comment Share on other sites More sharing options...
