I think that if you use descent class D powerful amp you'll get what you want.

IME, I believe it might be possible. My soft dome tweeters are not bright sounding by any means. When on the wire merry-go-round I tried a few silver plated copper interconnects which did brighten up the highs. But compared to copper, I did not like their tone: cymbals sounded like metal on metal instead of wood/plastic-tipped on brass; Miles' muted trumpet sounded too piercing/steely, and same with violins. BUT, since his tweeters are different than mine, along with his ears, brain, and room, perhaps he might gain the benefits (added crystalline clarity) but not the anomalies. It is worth a try. Some manufacturers offer trial periods, or buy used and resell. I say, DO IT!
You can emphasize certain qualities by making cable choices. Silver tends to highlight the treble energy that is there. Also you amplification as already changed to pure SS and class D inparticular can bring out the treble in some systems. I have had to go the other rout trying to warm up and fill out my sound which I think I did well in my system.
Amps might help. Some amps are certainly more forward than others. Or an EQ of some type.
People (including myself) are raving about the DSPeaker Dual Core. It has digital DSP for bass but also a very customizable EQ, along with 4 settings that can be saved.
A/D/A conversion with it is also remarkably transparent. I use it for both analog and digital inputs.
Haven't actually played with the treble or non-DSP EQ controls yet. But this is one powerful little unit.
Can "Dark"Sounding Speakers Be "Brightened"UP???
Yes. There are many ways to arrive at a similar destination. Dark speakers can be lightened up by using brighter gear and/or cables, and vice versa. Many people do this without realizing it. They may say "that cable is too bright", not realizing that they are running bright speakers.
I ran Verity Audio Parsifal Encore's which are very dark sounding, they are the first speakers I ever heard where silver cables sounded good. I also found that more revealing electronics worked well with these speakers too. ARC and VAC worked better than Cary or CJ.
A lot of this is in the synergy between the speakers and the amplifier.
Your speakers might be brighter with the same amplifier than his speakers paired with the same amplifier. Cables may make a difference, but frankly, the gear will make a bigger difference than cables.
I would strongly consider a different amplifier. I bet the Wyred4Sound Mini Integrated for $1500 will be more transparent and extended.
The problem with changing other stuff to 'fix' this is then the person is stuck with all sorts of stuff fixing some problem or other..
On the other hand, maybe the problem is not even IN the spaekers to start with..
So just get other speakers to try and see if it IS ust the speakers..
OR, have your friend bring his over and try them with the op's stuff to see "is it the speakers"??
So true Elizabeth. I ran into this problem once and thought it was my speakers. I put my old ones back and low and behold it was my new amp and preamplifier. I gave it three months of break in and nothing changed. The amp and pre were from the same company as well and were meant to be together but they sucked to every single person that heard them. That was when I started to take advice from all of you on Agon (with a grain of salt). The best advice ive ever been given is in home audition. If you cant do it, don't buy it. Its that simple. If you don't you're setting yourself up for disappointment. There is the possibility that something is broken, wired incorrectly or a setting is botched.
As a former SF Concertino owner -- no. You can tune the sound to shift the balance towards more top end illumination but these speakers are very midrange focused with subdued treble such that that is their sonic signature, IMO. Beautiful with voices and stringed instruments, terrible with rock. They sure are great looking speakers and so well crafted, though.
Try Cables First...Most of mine are silver coated copper, not by design, but after much trial and error. Best clarity and transparency, bass impact and midrange tone. YMMV. I strongly suggest you try Mapleshade speaker cables. It will brighten and make the sound more lively. Try this before a more expensive change.
They will be stark and stunning at first, but will mellow somewhat with age.
I second Wilsynet and Elizabeth in that the (main) problem you are hearing may not be the speakers. As Eugene81 reports, the speakers may be midranged focused but you may be able to improve things to an acceptable level by making other changes. My recent experience swapping around IC cables showed significant changes in the HF presentation between even very good cables. My overall experience has generally been that "darkness" (being a somewhat warmer than life mid-bass, less extended treble, and a focus on body and depth vs. resolution and detail) is sometimes a function of the electronics. Personally, to my preference, some of the best sounding gear I have owned had a touch of darkness.
Some of what other posters have said have got me thinking that you may just have a very warm midrange speaker that nothing can alter to the point where you will be satisfied.
OTOH I have a specific cable suugestion to try which are the all high purity solid silver cable called Silver Lace by Homegrown Audio. They are not overly expensive in the era of precious metal haording. If you have money to spare then the Silver version of the OHNO cast crystal silver cable may work as well or better.
I bought Jena labs pure copper for speaker speaker cables used they were still big money to me. I am pretty sure she is making a cast braided silver cable these days but again they aren't cheap. Jena is by no means very expensive compared to some others so it's not an outrageous compararitively either. There are other manufacturers that use it VanDenhalland several others (sp?) If you search you'll foind the others.
Ultimately all this tweaking I did, did not give me the sound I really wanted. I was fixed on keeping my JM Lab Focals and the I got a chance to buy some relatively potent tube monoblock poweramps.on the cheap I did so The search was over but I always wanted a 6SN7 preamp because I collect them and had only driver slots on an integrated to use them in,So a I snatched an AE-3 preamp(a Cary subdivision) which use 6SN7s to do the amplification and some other jobs in the pre.
I was simply delighted with the results all I wanted and more. My audio buddies always asked what did you do to those speakers they are sounding great ? I told them nothing.
So the posters sayit may be your amp might be right. Still others saying you can't make the seakers a bit leaner may be right. Thus do try several amps. My personal audio victory took years and lot of amps.
If you decide to try tubes get a modern pre or power amp they have sparkle and life and they aren't your Dads Fisher/ Pilot/ etc. I could hekp you optimize the tube choices if you take the plunge.
The amp should really have plenty of sizzle so it's surprising try a different pair speakers and see if it is the speaker. Otherwise the next question is what speaker should I buy.-Panels?? I don't like a lot of treble energy. I like speed transparency and stage wich my system has, it is by no means a sludgy dark overly warm sound. All the effort I (and $) I did spend was to rid my system of harshness and digital hash, even from my TT. Hey it's an adventure, If you buy the easy tweaks first go ahead but the DSP I looked up and it cost 900 euros, big money.
Good luck a lot of probably fun times await while you experiment your way into a more enjoyable system.
If a previous owner of the same speakers says that it just isn't that extended, then I'd go with that. The most important components in a stereo system are, in order: speakers, speaker amp synergy, amp, preamp, source.
There's only so much you can do to change the fundamental nature of the speakers, and speakers make the biggest difference.
Back in the late 90's when I first heard the Concertinos at a Tweeter store, they were driven by a Marantz receiver (no idea on the model). Listened to a variety of material and I heard plenty of "sparkle" in the treble. Flash forward ten years and I finally purchase a used pair. I paired them with a VTL tube amp. Unfortunately, I heard much of what your friend describes. So basically I'm thinking that Concertinos are picky about amplification.
just looked at this post if this has been answered...sorry.
If the crossover has an Lpad, with any pad on the tweeter, yes, you can reduce the amount of tweeter pad without changing the crossovers function. If the crossover has no pad or if the pad used was a single resistor figuring its resistance into the tweeter, then no, not easily, you would change the crossover design.
