Been quite busy lately guys....Re-setup my AV system, the KRP (only 14hrs on it now) last weekend. Not done Audyssey as yet...need to go check out the XPA3. Watched some sports on Astro HD, pretty darned good.

Need to move around my speakers and sub as the room accoustics has changed a little. Need to spend some time setting up the rest this weekend. Then some FR curves to go. Hopefully, if the AS-EQ1 is up north, can do some checks with it as well...

I think it will take another 3 weeks to complete setup. Then need to calibrate the KRPs to ISFccc.

Tested the PB13U today for the 1st time. What can I say that has not been said yet?

Bass is what u want, so u get. Forget the Buttkicker if u want tactile sensation! Get a PB13U man.

Seriously, this is one beast. By size, sheer power and the amount of air it pushes. I also ran some curves to test AS-EQ1's strengths at htkaki's pad.

HTkaki has a nightmare of a room for audio and REW showed them. REW also showed how effectively the AS-EQ1 dealt with it. Great unit.

I'm sure someone will ask how the PB13U compares to the other beast. This is my assesment.

One is an earthquake and the other is a tsunami....They have different characteristics yet both excel in different areas. The PB13U does the low rumblings with a lot of air being moved. The Submersive does it as well with the opposing 15in drivers, albeit in its own way. The amount of the bass is the same, the feeling derived is different. It depends on what u r looking for. The Seaton I tested still had a lot in it and the pad was restricting it. Same thing I felt with the SVS as well.

Bass freaks shd give the the PB13U an audition since u can actually audition it. If u r looking for pure clean bass, a Seaton might be ur cup of tea and u shd make friends with ron before deciding. They both achieve owner satisfaction, however they take different approaches.

The AS-EQ1 is a must have for those with bad room. htkaki's pad would have been way too boomy and un-tenable were it not for the AS-EQ1.

I will try to post the curves this weekend.

BTW - htkaki, thanks for hosting me. Say thanks to Mr. Tan as well. We need to see if he manages to find the sweet spot in his system.

Guys,

I have to apologize for not posting the charts. My bad luck, I made an error when saving the files correctly after htkaki, Mr. Tan and myself looked at them. I will have to re-do the measurements the next time I am there. I'm sorry.

benben79,

Before attempting to answer your question, can you explain what u will use the subwoofer primarily for? Movies or music? If both, can you let me know how many % of each? This is important before I answer. I carried out some frequency response charts for the PB13U recently.

To give u an example in the room the PB13U had usable output till 12Hz. Low enuf?

However, for music, no real instruments actually go so low. The pipe organ is one of the few instruments that go.

Hence, it is important to understand what u r actually looking for. For movies, hell yeah, there is content mixed at even 10Hz or 5Hz. Loud explosions and rumblings, to name a few.

BTW : Bass freaks, check out SpiderMan2 when Doc Oc demoing the use of his claws to control the fusion reactor. Plenty of earth and plaster ceiling bass here!

Technically, tentacles and claw...as the tentacles have claws at the end of them.....maybe tentaclaw...

Something new?

One note, different rooms have different responses.

SVS us "upping" the ante....I wonder how the subwoofer community is going to react to the 13s and 16s.....

More choices for us, and with htkaki as the distri we can expect some pretty good launch prices, as he states.

Wow! Thats a 6dB increase from Audyssey. Do you have a SPL Meter to verify if the speaker levels are matched when u add 6dB to the sub trim?

Run to run variation and the mic variations of +/- 2dB but 6dB seems kinda high.

The 59 is in relative terms. If you go into setup, u can change it to absolute and you will know how many dB is its. It depends on your trims as the trims will decide the max dB on Onkyo systems.

I doubt the PB13 would distort, u don't have anything to worry about that. It has plenty of headroom.

However, what I meant was that it would be hotter than the rest of the speakers. What can happen when it is too hot, is that it can muddle up the rest of the spectrum as it will take longer to decay. However, what's important is what u like...don't worry abt what I blabber. So enjoy ur sub....

Yeah, my bad, read wrongly. 3dB is no problems.

Its more accurate I believe. Boomy is a sign of a peak in the bass, not necessarily intended. U never know until u run a frequency chart.

U like it better this way? Was the bass that high to start with in the track?

No need to use BFD for room response checks. BFD is necessary if u are planning to add filters for equalization.

Let me know what help u need with REW.

Get an external soundcard or a soundcard that has a separate line in and line out. Thats vital.

Enjoy REW.

Also of course u need a SPL Meter. Radioshack for response up till 3KHz. Galaxy CM-140 for response up to 15kHz.

Extremely happy for u....

BTW : Welcome back...

So which sub did u actually buy? F113 in da house already?

SVS-ers....

I would advise u to revisit I-Robot with ur SVS. I believe this was released at a time when most of u did not have a bass giant. Pay some dues to Proyas's flick and u shd be in for a bass treat.....Really low bass treat.

The tunnel scene for one. The seems to be low bass through out the movie.

mpyw,

Actually the LFE is all around. There are plenty of low LFE moments.
