Yes, exactly correct. It's a 1:1 ratio. No need to re-run Audyssey; it will maintain the overall sub channel level.

Ah, excellent....I'll do this tonight...thanks for the advice!

I have an AS-EQ1 as well, if I re-run the setup in the future, should I leave it at -6 dB or set it back to -16 dB where the software measured 75 dB in the room and just change it after?

Hi Ed, does this also apply to the BASH 750 amp?

I know that without the convenient digital display it's hard to know by how much you are increasing the amp gain, but just wanna know if the same principle applies. I can use a SPL meter to check the level.

I'm interested in the answer to this also.

And a second related question, if I like to run the sub hot (say +3dB) post-Audyssey, should I bump it up in the AVR or at the sub amp?

can I check please that running the sub at a lower port setting on the rear - than the physical configuration is ok ? (I think it puts less strain on the Sub anyway ?

ie:

2 Ports Open (PC-Ultra) - 15hz tune
amp panel set to 10hz tune

it just seems to remove a big room boost around 25-35 hz that room size doesn't correct - small/medium/large seems to have more effect lower down in the spectrum - sub 18-20hz

thanks

I'm starting to think the obvious answer is yes. There is no way I would read 75 dB at the new level when I take the first measurements.

The best change I've noticed is when listening to music in Direct mode.

Not OK - this leaves the sub unprotected from frequencies below tuning. The ports unload below tuning frequency leaving the driver with little resistance to bottoming when the subsonic filter is set lower than physical tune.

Thanks,

ah ok thanks - I thought it was other way round - I thought setting the subsonic filter to a higher frequency than the actual port tuning was bad

just re-read the manual and you are quite correct you shouldn't set subsonic filter lower than port

thats surprising as if anything in that setting it seemed to be cutting quite a lot of bass - but I'm no expert - its a pity as gave me a nice flat response - never mind - I've reset it back to be the same as the port

i don't know which sub you have, but you might be able to tune it lower than 15 Hz (my PC12 Plus can be tuned to 12 Hz and the filter at 11 Hz);
this also could lower or flatten your bump.

it's worth a try.

The original generation Sledge amps had a higher noise floor than we preferred (it was tied to the input sensitivity and associated signal/noise floor). This was corrected in subsequent production runs and the lower noise floor amp has been in circulation for a few years now. While all amps have a known S/N ratio and an audible noise floor, the improved version is very good and we've had no issues or complaints about it.

Mitch,

If you're up to experimenting, rerun your system so that your final subwoofer level in your preamp/receiver winds up at -4. At one time, that was considered optimum for giving your headroom in your preamp/receiver and a high enough signal to your sub so that the auto on would come on.

Thanks.

The BASH amp has an analog gain stage which functions totally differently. It is not sensitive to gain setting and can be driven to full power at much less than full gain. So with the BASH, I prefer to just set the sub channel level somewhere around -5 and then adjust the gain until you obtain the desired SPL.

Hey Ed. I'm a SVS customer(2 CS Ultras), any chance of buying a Sledge 1000 amp to replace my old Sampson?

The Sledge 1000 cannot drive both amps at the same time, unless they were wired in series for an 8 ohm load. The amp wouldn't make full power into that load, but that's not necessarily a bad thing considering the application.

No promises but send us a note to custservice@svsound and we'll at least kick it around.

I did it exactly that way and been enjoying it for a more than a year now. I still like this beast very much. Never fails to impress any visitor

Bass, please. Shaken, not stirred.

Question for the owners!!

I've never heard a 13" sub, is that the best of both worlds? 12 + 15 subs are both great and sound so different, sites this sub play a sound somewhere in the middle. Thanks for any info or a link to it

Glad you are liking the performance improvement. If you re-run the AS-EQ1 in the future, set the subs to 75 dB (the AS-EQ1 needs this SPL to properly build an EQ file). After the EQ file is built, the AS-EQ1 won't be affected by the sub channel level or the overall sub calibration level. So you can perform the same gain maximimizing technique again after you re-run the AS-EQ1.

Hi Ed,

Do you mind sharing the specs for Bash and Sledge amp? PM would work for me if you don't want to post them on the board.

thanks

So, one of my 2 Ultras had its BASH amp go out and SVS is warranty replacing the plate amp with a Sledge amp (awesome company). Now I'll have one BASH and one Sledge unit. Anyone foresee issues mixing and blending the two manually before running mono sub Audyssey? I plan to level match them again and go from there. They're both equal distance from the main seating spot (my spot). Are there any slight group delay difference issues I might have to deal with now with two different amp styles?

I've been quite happy with my pair, but it's been kind of fun with a single unit, a bit more texture to the bass, a little more clarity. This is probably due to non-perfect blending before with my pair, but I'm always tweaking the system (don't we all?). I suppose if it's too much trouble mixing the two amps, and since I'm no longer as worried about all around the room even bass response, I may move one upstairs and start a dedicated 2 channel system.

Why do all of my threads suck? Is there an internet posting school somewhere? -wes k
