Since it happened on both speakers, I'm inclined to think it's something to do with the speaker design itself. Normally if driver issue would affect 1 only, unless really bad luck both speakers also got bad driver.

Ha-ha, bass will be insane with 13 Ultra in his room.

To be realistic the main things that will happen are: doors will rattle, windows too and very likely the plaster ceiling. Loose items on shelves will also vibrate. Loosely hung paintings might fall off...

But no blinds flapping or Dali coming out of the mounts (unless not tightened down properly).

I don't think they are talking about the pink noise. It's the Audyssey test tone (I think it's called a 'chirp') which causes the funny sound.

Yes, dealing with local govt agencies and authorities can be very frustrating.

I think the heavy weightings below 25Hz are due to mic sensitivity in the SPL meter.

Will be eagerly awaiting the FR from the PG bros on the EQ1

That's another thing, avoid dealing with govt bodies on Fridays if you can help it.

Sure I don't mind trying out the EQ1.

Different people have different tastes I guess. At least the SVS also caters for those who like big BOOOMMM!

Wow, you're at the bottom limit of the AVR sub trim at -15dB. This is after running Audyssey right?

Suggest you turn down the volume knob on the sub and re-run Audyssey so that the trim is higher than -15dB. Then your bass will be even more 'elite'.

Ummm.... I think I understand what you're trying to say.

Well, Audyssey will compensate for your sub volume. If you set your sub volume very high, then Audyssey sub trim will be set very low (-15 dB is lowest). Conversely, if sub volume very low then Audyssey will boost the sub trim (up to +12 dB max I think). So really it doesn't matter what is your sub volume as long as you don't reach the limits of Audyssey because then you go beyond the ability of Audyssey to compensate.

What you said: "Ok it is like this.........LFE input very large so by right ur sub output will be large but it can't output that very that much as it is being restrict by the vol control ( eg at 30% )" I don't think is correct. The sub vol control is a gain control, i.e. it multiplies the input signal from the AVR. So if you set at 30%, Audyssey will boost the signal (to compensate) so 30% x boosted signal = 50% x lower signal. Like I said earlier Audyssey will compensate so that some balance is achieved.

You cannot compare your trim settings to other people because their setup is different, e.g. different speaker sensitivity, different distance, different sub vol setting. All this will affect the trims.

Don't know why got such big difference between first SPL setup and your next one. Perhaps your test conditions were different? Different SPL meter?

Correct. It's not a master vol control in the sense of showing the absolute output. Namely, 30% doesn't mean you can only get 30% of the output. It's a gain or multiplier control, so in the end 30% x 10 = 50% x 6. The second part in that equation is the LFE output signal from AVR (which Audyssey will adjust according to your sub volume).

Eh Horny, just noticed you have the Velo SPL 1200. New addition ah?

When I say test conditions, it means all the parameters involved, e.g. was your setup the same? I think you said you changed some speakers (so this changes the test conditions). Was the SPL meter in the same position? Was the SPL meter hand held or tripod mounted? Was the target the same - one test you said target was 80 dB and another was 75 dB?

Basically to make two tests comparable, everything should be kept the same.

Hi. Quite a large area you have there. Depending on how you like your bass, 10" sub might not be enough. But this will depend on your taste, for example I think horray has the CHT-10Q (he thought the 12Q was too much for his living hall).

Anyway, CHT-R series has been discontinued (replaced by CHT-Q), maybe some dealers have old stock. CHT-10Q about 2.2-2.3k I think. Main attraction of the Q series is the Auto EQ feature and remote control.

People here can read between the lines mah. Especially when you keep ha...ha...

Some reading material about bass, from The Absolute Sound (Nov 2009): http://www.avguide.com/article/guide-better-bass-tas-197

When you say 'subwoofer EQ' you mean the EQ in the sub itself, or a separate device like the AntiMode or AS-EQ1? For those EQ built in the sub, usually it's quite basic and able to cut 1 frequency band only. Nothing compared to separate device like the AntiMode or AS-EQ1.

Audyssey in the AVR is quite sophisticated, but there are several different versions with different capabilities. Generally Audyssey in AVR tunes the whole frequency range, from bass to mids to highs. For the bass region it can do a decent job, but probably not up to same level as a dedicated sub device like the AntiMode or AS-EQ1.

That's the Thigpen Rotary Woofer TRW-17. Funky looking but needs specialised installation.
