Listener fatigue

[gilesw]

Yea in my lounge I do have a different type of chip amp but I am suspecting the ma's have to go. They have served me well over the years though. I've been looking at the rega rs7, ProAc Response D18 and epos epic 5. Time to whip the credit card out methinks.

Do try and arrange a home demo if you are able to Giles for piece of mind. If you are unable to do so I'm sure those with experience of the models you are considering will help guide you in the right direction

As stated earlier in the thread, you could add some in-line resistors to your Tweeters, they're cheap and can easily be removed if they don't solve things, or are no longer required due to other factors.

About 1 to 1.5 ohms should do the trick, much better than sticking a tone control in the path

Heya Will, I have modified the capacitors on the crossover years ago so that is definitely on the cards. Presumably what you are saying is that it's best to keep as much signal going through all the components and deal with the treble as late as possible in the signal path.

I've found a chap that has the rega rs7's and pro-acs so I'm going to demo them on Saturday. The rega's are going for £950 which sounds in budget for me.

Yes, this is what I did, as mentioned above. I put something like 3.9 ohms in series and all was well. I purchased a selection from Maplin (5 or 10W wire wound) Cost was about £1.50.

In fact I didn't even need to do any soldering, I just put them in place of the biwire jumper to test it out. I then listened to it and measured the results.

See my thread for details here: http://theartofsound.net/forum/showthread.php?t=18823

I did take a look at the crossover in my Neats, as they don't have a "classic" crossover circuit. In fact, with the Neat circuit, I needed to put the resistor in the 0V side of the circuit.

Bear in mind that a forward balance doesn't necessarily mean that the tweeter level is totally to blame. There may well be issues further down the frequency range as well, that could be tweaked with EQ. You really need to be able to accurately measure the response to see whats going on though.

Measure the room, once you see what it is doing then you can think about the possible fixes, also you can use the measurement software to find the best place to site your speakers and you , XTZ room analyser perhaps.

Heya Will sorry to bother again, will any of these fit the bill?

I think I'll just shut up now.

Hi Giles, the ones named 'wirewound' look like the fellows I'm using in a couple of pairs of speakers, although I got mine from 'Wilmslow Audio', they were marked as 1.75 ohm...my electronics knowledge isn't good enough to interpret that into Watts (V=I*R has left me scratching my head)

One other point I used mine on bi-wired speakers, so I'm not sure if there are any implications there.

They just bump up the ratio of bass to treble without affecting the signal...much

Hi Martin ...ah it was you that mentioned it earlier, should have given you a name check

Sounds like you have more experience on the subject than I

I just put mine at the +ve terminal of the tweeter and all was well...
