Hi, i have bought 4429 yesterday :música:, i`ve 275 + pre c2300.
I have 10hs aprox.
How many hs. for break needs ?
you heard important changes in the sound after break in ?
Hallo!
For me, it took a couple of day's to break in the speakers. Played very loud with good bass content. I am not so into this "break in" thing fhenomena. Yes true, all mechanical movement has some break-in period but it is not so trivial.
It will sound better as time goes by. Enjoy!!
You have a great system!
Have done some changes to my system. Running my 4429 with Crown XLS 2002 amp with AudioLab M-DAC, mostly for TV listening.
Still have my Mcintosh C48 driving both Crown 2/600N drivcore install to my 4635 and Crown MA5000i driving my new JBL JRX225 speakers. JRX sounds great.
A tip, run one more MC275 in mono/speaker will sound even better.
Thank you !
Today maybe i can ad another 10 hs for complete 25hs aprox.
Just leave them playing all the time but lowered gain at night, etc. That's what I always do and it gets the break-in done faster.
Grats on the new speakers!
bass still tight after 25hs.
I saw in many reviews, "The bass is tight and clean" .....and anothers: " Deep, visceral bass at all listening levels "
Is tight or deep (bass)?
I suppose that after 100 hours it should be more deep? I love a deep bass
4429 does not play deep bass. The bass-reflex tuning is around 50Hz, if I remember correctly.
But it is very very tight bass. Wonderful speaker.
i see from manual
FREQUENCY RESPONSE 40Hz – 45kHz (–6dB)
CROSSOVER FREQUENCIES 800Hz, 7kHz
i play for break in woofer, 20hz and move excellent.
I dont understand if say 40hz-45Khz how can move with 15-20Hz
JBL S3900 say 33Hz-45KHz, its tight bass also ?
For example S3900 say:
FREQUENCY RESPONSE 33Hz – 40kHz (–6dB) CROSSOVER FREQUENCIES (HZ) 850Hz, 12kHz
Hi
haven't posted here for a very long time, but since I bought some 4429 a year ago I can help...
I found that the speakers needed a very long breaking in. When they where new, I found the midrange and treble to be quite recessed. Over time, the compression drivers get broken in and the overall balance improved. Still the treble remains very soft and never agressive. The bass level doesn't really change over time.
The bass is not deep, as other people pointed out, it is very tight. Nevertheless it really depends on the recording, you'll often hear deep bass anyway. As with any speaker, depends from the acoustic of your room and placement.
I run mine with a ROTEL RC-1590 pre and two ROTEL RB-1582 MKII power amps. Very neutral and dynamic.
40 Hz is the bass extension at -6 dB. Maybe you would hear 20 Hz, but at a lower volume. Again experiment with placement and amplifier. These speakers where made for the japanese market so they have lean bass by design.
You need quite some power to get good bass, I tried several amps and all gave different results.
