PreSonus Temblor T10 by r_cc_c
Setup,itunes on windows laptop - digital out to Denon AVR 4308 without any EQ or room correction - setup to 2.1 with standard 80Hz xover point. Satilite speakers are Klein | Hummel P110 (the passive version) Comparing with Genelec 7050B subwoofer (A bit unfair but the 7050 is what I have)
Background - I want to freeup this 7050B to my other 2.1 Genelec setup so I can have 2.2 8030+7050.
Default Setting on the Sub - (Just to note this is my starting point and I played with all the adjustments)
- xover freq set to the highest 150Hz
- denon subwoofer Pre Output (RCA) connect directly to Left (or Right) channel input (RCA) to the T-10.
- Output volume set to 0dB
- phase setting is 0 degree
I played some music with this setting and found there is too much bass.
So I lowered the T-10 output to balance out the sub with my speakers by ear as comparing to what I used to with the Genelec.
I notice the imaging is all destroied. Listening to the P110 alone sound a lot better than adding the sub.
I felt the bass are containly coming late. It is not just a few micro-second. This is recognizable delay in hundreds of milliseconds. I played with the phase switch but didn't hear any difference.
Also move the T-10 to different location in the room. The delay still present.
In theory, I can kick in the Room correction from the Denon to correct the delay. But hey, we are talking about recording and monitoring here. Personally, I want to get the right piece of gear, not to cover or correct a problem by engaging more electronics + DSP.
Now the overall sound qualilty.
Simply said, I rather hear the music without the T-10.
As for the Genelec, it is not the case.
- The T-10 added a lot of WOOFing to the music which wasn't there in the first place. (comparing with the genelec) I turn up and down the volume and the xover freq on the T-10 to see what it does to the overall sound. The volume control let me know that there are a lot of resonance coming from the enclosure. When the T-10 volume is up, the enclosure vibrate severely.
Lowering the xover frequency helped. In theory, this second stage filtering is there always. But if the T-10 is filtering at a higher point (150Hz) and left the rest of the freq response flat, the LPF from Denon should match up with the satilite speakers. Lowering the xover point does help clean up some of those random resonance, due to the reduction of content being fed to the internal amp & drivers, at this point, I just cannot trust the T-10 any more.
Overall, I found the T-10 is producing more noise than music. It is simply not the right tool for music studio. For explosions from movies...maybe.
I didn't test output of the T-10 to Satilite Amp+Speaker. Perhape that might do wonder but I highly doubt it.
I returned the T-10 and I do not recommend it to anyone.
