No bass in the Proac Response 3


I've just had the opportunity to buy a Proac Response 3 from a fellow agon just recently. One of the foam the 6.5" woofer was
torn ( with holes) so I already had it replaced with brand new foam. The treble improved quite a bit once I had the foam replace. The midrand is still the same and I have to say the Proac midrange is beautifull. I can sit and listen to female vocal (Krall, Elle, Cassandra) music all day. There is no sign of harsh or etch at all.

However, my problem now is that the bass is nowhere to be found when I play rock/pop. I do the regular Proac reccommended speaker placement of 2 feet away from the wall and the deep bass , mid bass are all but lost. If I moved the Proac very close to the wall then I get stronger bass, but now my image and everything else got all messed up. A simple analogy would be like I don't feel the singer is standing in the rooming sing anymore once I move the speakers toward the wall. Everything is just so flat ( 2-d), but the bass is good.

The most simple weak link that I can see in my system is that maybe the Krell integrated is just not big enough to produce the kinda big bass that I used to. But another interesting thing to know is that before I got the R3, I also got a much smaller Proac supertower that produced bass twice as much as the R3; and the R3 is twice the size, but lacking in the lower freq department.

My system is following:
Krell KAV-300i (integrated amp)
Arcam DV-27 (CD player)
Sony DVD player + PS Audio UltraLink DAC
Proac R3 (Full range speaker)

Got similar story and think that good speaker cables could improve your bass freq. Used to have the Krell 300i but now replaced with the Atma Sphere MA1 Mk3. Even with the MA1 power, the bass still lack of impact/realism. After testing so many bi-wire product, currently, very happy with Anticable for the HF and the Canare Quad for the LF. On the subject of Proac's bass capability, when the Proac Response 3 is paired with the AudioValve Challenger 115 and Tungsol 6550, I've experienced the most realistic bass ever i.e. growl, impact, pressure... Btw, systems owned include Joule, Shindo, but most realistic bass come from this combination Audiovalve + Proac...
I didnt read all these posts so if someone said this already-- sorry-- but when you refoamed-- you had to take the woofer out of the box, right?
Did you maybe re-wire out of phase (easy to check) or not tighten the screws down enough to seal the woofer back to the box tight? The Response three should have pretty significant bass....
This is response to previous two responses.

Abramsmatch , yes I made sure that the connection were properly in phase.I even went ahead and followed instruction from one of the gentlemen who posted earlier and used a small AA battery to bias the woofer. It worked great .If the woofer were incorrectly connected the woofer would move in, instead of moving out (please see above) if connected inphase.

Indofunka, I know how valve/tube amp sounds like. They sound seductive, but I am a freak for bass and it just doesn't cut it for me. Currently , I've got my hand on a real Krell DVD/CD and sold away my cheap Sony DVD and the PS Audio DAC and first impression is that it sounded way better than what I had before. Boy, the combination of Krell amp + Krell CD + using balanced cable is just incredible.

However, on a side topic, the Krell DVD Showcase I just bought is giving me a lot of problem with playing scratched disc, and etc... Plus every 20 sec or so, depending on the disc, it would shutoff. This is the most frustrating thing I've seen. I've had cheap 15$ DVD players made in China/Japan that play scratched disc and do not have mechanism to shut down just the like the Krell that cost 500 times more. This is just so stupid. If anyone has experience with this problem please let me know . I haven't contacted Krell yet. As I am trying to get hold of the invoice form from the dealer so that I can get warranty.
I made suggestion about the cables, they made a noticaable difference in my setup. I am glad Krell 300i provides the bass quality you are looking for, but to say "tubes" don't cut-it is wrong. Have you experience Joule, Atma MA1, Shindo, and.or Audiovalve Challenger with Tungsol 6550??? There is no comparision between what I listed and Krell 300i. Like day and night, 2D and 3D :) I could also suggest another SS integrated amp for $700 that blew the Krell away!

(Scan-Speak 18W 8452 bass/midrange speakers are fitted as original equipment to many high end speakers such as Pro-Ac Response speakers, Scan-Speak 200, Celef monitors, Carlsson OA52 and 53 and others)

foam surround repair kit (stock code 0653K) for Scan-Speak 18W 8542 contains the same genuine surrounds as originally fitted. If you use any other surround on these speakers you will suffer greatly reduced bass output.
