Activity Stream

So l can respond correctly please describe your loudspeaker and amplifier set up

OTOH, why do we have to run the HF output through the active xover, just for the sake of the highpass for the 3107? Curious what would happen if we...

thanks for the input, guys. I also thought about giving up on very high efficiency woofers. Might be the case that i will have to sell the SVS in...

I tend to agree with Todd. But the E145 is not your everyday MI bass driver, its more of an exception. Sort of a special driver among the MI herd....

I enjoy the enthusiasm in these diy forums and l provide some useful technical insights to keep the discussions constructive and productive. The rest...

The other less obvious thing to appreciate is that residual noises sum together. Unfortunately this means that even if your source component,...

Okay. Firstly l will clear any confusion on the JBL 5234A and the 5235 SN. Putting aside the product differences I’m referring to the JBL spec...

JBL E145 or the pro equivelent may get you to where you want to be if you can find a pair.

Thanks! The thing is - and i am not sure if i got this correct - but the LF outout of the 4507/2226h itself is fine for me! I don´t listen to bass...

Ian, the SNR of the 5235 is not given for full output level and is -90dBV, with its output stage which is different from the one of the 5234A. With...

High sensitivity, say around 100 db 1w/1m, is achieved at the expense of low bass. Even if you went for a high sensitivity MI driver you would still...

Good outcome. How did you measure this? Btw the JBL SN measurements are at the full rated output of 6.2 volts. Because the residual noise is a...

That's what I thought! I acquired these speakers/cabinets for almost free, and my initial plan was to upgrade them with Altec/JBL Hi-Fi woofers. I...

Is there a JBL woofer with high sensitivity and reasonable bass response that you can recommend? The 416 is quite rare here in Europe. Thank you.

Unfortunately we are treading into the area of personal preference, but the Altec woofer does "sound" like it produces more bass. It can be used very...

Thank you very much for your valuable advice. Regarding the recommendation of the 416, will it inherently produce "more" bass without requiring...

You are probably finding the need to crank it up due to the lack of LF output of the 2226H woofer without EQ. Remember the Fletcher Munson curves? By...

Really, I can read... I just now realized that this is asking for the 811B–830 network... Here's a clearer copy: eso

And these two kids and absolutely stratospheric. You can find videos of here doing recitals of Franz Liszt works when she was only 14. And now...

This video from the Big Ears Festival is great. I saw them at a small/mid size venue in Los Angeles a couple yers ago and they were great. Tenor...

Thanks for the tip. Interesting! https://www.youtube.com/watch?v=qB4-eH5mGf0 Thanks also to our sons and daughters for inspiration.
