Don't be selfish, share your ULS-15 pics!

[sbeveraggi]

Surprisingly, there seem to be very few ULS-15 owner's pics posted.
Only lanion and Mia&Lana's dad have posted pics of this beast so far...
Anyone with the veneered or piano black finishes at home?:cool:

[John H]

My ULS-15 DuelDrive system arrived yesterday. I just finsihed installing them into my system. I put them upfront in place of the MBM-12's to test out.

The finish is spectacular!

what are the rest of the speakers in your very handsome system?

[sbeveraggi]

Wow!:D
Those are beautiful subwoofers!
Impressive finish also. Thanks for sharing.

Do they come well protected from an eventually careless shipping?

From what you see in the second picture they also come with foam corners. Fairly standard packaging.

John H - nice system! Any thoughts on the ULS-15's performance for music? May I ask why you have dual ULS-15s AND dual Epic Conquests? Are you doing a shoot-out and returning the 'loser' to the manufacturer for a refund?

A slightly different question if I may - what acoustic room treatments are you using? From the pictures it looks like a GIK D1 diffuser in black behind and next to the TV and Tri-Traps in the corner . . .

[Larry7995]

I am also curious about the dual ULS-15s AND dual Epic Conquests?

Thanks for the compliment,

I can't comment on the musical performance of the ULS-15. My system isn't really setup for music.

I am not doing a shootout I plan of keeping both pairs.

I moved the ULS-15's to the rear of the room and installed the MBM-12's back up front with the mains. They seem to sound best with nearfield placement.

Yes those are GIK Tri-Traps in the corners. I just hung the diffusers after speaking with Frank at GIK. I am planning on switching out my Definitive Technology bipolar speakers that I have been using for 8-10 years for a set of Klipsch reference series. I will be changing out the diffusers on the front wall for some 242's at that time.

And it goes on and on, doesn't it?

John, have you tried using the ULF trim control yet? I think that this may help you take better advantage of room gain.

We did an interesting experiment with Ron's quad ULS/quad MBM system: We put them all in the nearfield, with each MBM-12 on the floor on it's side (with woofer firing forward, and port firing to the side), and we put the ULS-15 stacked on top of the MBM-12 (using something soft in between).

This worked out extremely well!

Pete,

No I have not experimented with the ULF trim. Could you explain how the control functions. I know it compensates for room gain. Could you give some examples of room size and ULF control position setting. Smallest room ULF setting vs largest room ULF knob position setting?

Thanks,
John

[Pete_Hsu]

Hi John,

Without measurement gear, it's best to simply experiment with the knob to see what works best. I would try it first about halfway up, and then try it all the way up (ie. at 50Hz), to see how it compares to the 16Hz setting.

Basically, the ULF trim will let one roll off the lower bass anywhere between 16-50Hz. This will allow one to take better advantage of room gain, and to maximize amp power and headroom at higher frequencies.

Sincerely,

[a3plew]

Which ULF control position rolls off the lower frequencies?

Thanks,
John

[Pete_Hsu]

John, it's the knob to the right of the phase switch and to the left of the crossover knob, and is labeled as 'ULF Trim', with min marking as 16Hz and max marking as 50Hz...

Hello Pete,

I wasn't asking for the physical location of the ULF knob. :)

So is the ULF control basically a highpass filter? What is the slope?

Thanks,
John

[Pete_Hsu]

Hey John,

I think I misread your question, sorry :)

Any position along the ULF trim dial will gently roll off lower frequencies. With the knob in the 16Hz position, the response will gently roll off below 16Hz. With the knob in the 50Hz position, the response will gently roll off below 50Hz. And with the knob somewhere in between, then the roll off will be somewhere in between 16 and 50Hz. It's not simply a sliding high pass filter. The rate of rolloff depends on where the ULF trim is set.

Hello Pete,

I am currently working on a nearfield configuration of my duel Conquests/ULS-15 DuelDrive System/ duel MBM-12's

Maybe the Conquests on their sides with the others stacked on top with Subdudes in between?

John

[Pete_Hsu]

John, it won't hurt to try that, although it would be best to put the MBM's on the floor to help avoid floor bounce effect.

Dr. Hsu and Pete came over and helped reconfigure my QuadDrive ULS-15 and MBM-12 x 4 opting for a symmetrical nearfield implmentation. After performing exhaustive measurements for all possible sub placements, Dr. Hsu's conclusion was that greatest headroom (20hz+ nearfield) was more favorable at the expense of deepest extension (single digit hz, farfield) for the best overall experience and program material practicality in my particular room. As some may recall, my room imparts certain suckouts when subs play from front and rear. Farfield, the ULS-15's can extend down to 8hz. The tradeoff is that they have 20db less output at the same amp level settings compared to when measured nearfield. Up close, at my listening position, the ULS-15's drop off below 16hz but are coasting along with that 20db advantage. The above graph reflects no smoothing, no Audyssey. For now, I am evaluating the DEQ2496 for sole sub EQ duty, while retaining Audyssey for just the mids and highs. Here's the accompanying waterfall. I don't know how to look at these yet. I suppose the goal is to reduce the decay times as much as possible.

Hello Pete,

Could you please explain floor bounce effect? What would be the difference in MBM placement in the stacking configuration?

Awesome, thanks :)

The impact from this arrangement is just scary. I still remember it vividly like it was just yesterday.

[Pete_Hsu]

John, all I meant was that if you put the MBM woofer relatively high off the ground, then those higher frequencies will be more susceptible to the floor bounce effect which is seen as a dip in the upper bass response. For the low bass sub it's not an issue due to the frequencies being handled by the true sub in such a setup.

[mike c]

hey Ron (ML dad),

what does the front look like now?

[Mia&Lana's dad]

just the L/C/R arrays with empty space in between them

[John H]

Hello Ron,

Beautiful! :cool:

Did you retire your Conquest? Or just did not feel it would work in your particular situation? To large and bulky? What are your final conclusions of the Conquest?

Thanks,
John

hahaha omg, that quadstack. NUTS! :D :eek:

I still haven't been able to A/B them the way I'd like to make any final conclusions. However, I am certain that I prefer the sealed sonic signature. The Conquest is just sitting outside in another room for the time being.

Do you have independent output control over the subs where you could quickly switch between both (calibrated and EQ'd optimally for each)?

[bsoko]

Hello Pete,

John

Took a clue from you guys and turned my MBM-12's on their sides firing into the room and stacked my Polk Monitor 10's on top (mains). Put Alerux Subdudes in between the floor, MBM, and monitors and this stacking got the monitor tweeters at ear level. Made a big difference in all bass. More dynamic and punch. With the monitor wide sound stage and the mid bass from the MBM's it feels just like a THX theater in my living room.
