I have finally set up the reverberation injection. My DSP3000 turned out to have some problem (vanishingly low output), I hunted DSP100 and got a pair of Focal Twin Shape speakers as the RI (2x5" woffers + 2x 6" passive radiators + inverted dome ...

Either they decided to ignore the physics or I got the physics of rotating liquids wrong https://klaudio.com/kd-mgz-tt1-magnezar-turntable...

I'm 20+ years professionally in quantum science (quantum foundations and quantum information), I won't even open that video. To at least partially give back what I have learned here, I volunteer to educate anyone from GSC who wants to learn the basic...

Thanks Anthony! What immersive system have you been using? Do your immersive channels process the actual music? I'm going the Yamaha DSP path where according to Romy RI speaker quality doesn't matter much as they produce only auxilary "barking" sound...
|
|
Impressive system Anthony! May I ask a delicate question: How much +/- have you spent on your system? I'm asking out of pure curiosity to compare with prices of the garbage produced by the so called high-end industry. BTW, nice idea with active m...

Thank you Romy and others for the input! For the time being I will concentrate the efforts on the Yamahas.

Thank you! I’ve located anp paid for DSP3000. The RI speakers: what are your experiences/thoughts?I obviously miss bass energy with Dannoys. Logically, I should then look for bass capable satelites or this logic doesnt work?...

[quote user="Romy the Cat"]If you would like to experiment with it do not rush to buy
the DSP-100 and there are many others and better Yamaha and not Yamaha units
that do the same. If you would like to I will give you a guide over them. The reason...

[quote user="Edgar="]Friend after friend leaves astonished saying how "dialled" the sound is and the system was literally slapped together via the path of least resistance just for proof of concept. Development ended there other than adding 2 more br...
|

[quote user="Edgar="]I think the issue is system power levels not F3. I think The efforts for implementing something under Dannoy is more toeards improving that not so much lowering f3.Dannoys open bottom end sounds really good. I'd be keen to preser...
|
|
I've been thinking how to counter your argument but looks like I cannot apart from a "majority vote" argument: Using sealed subs and pahse aligning them to Tannoy, below f3 there will be 3 membarnes in phase (Yannoy + 2x active SS) and one out of...
|
|
Edgar, very interesting idea. I see if I manage to get some extra amp and drive the SS like you say.
Also the idea of 15" Red + 2xSS sounds cool. Maybe someone has 15" Reds and could try (they are pricey)
But I still have one ...
|
|
Im not sure if you understoid me or me you. I was not talking about adding another cone to the reds in the same volume. But rather adding your bass modules with two scanspeaks, one active, one passive.I want to enjoy orchestral music too :) btw Giuli...
|
|
Edgar, now I understand what port you meant, the effective one in the Dannoys and the associated phase flip. I've never tried adding bass to a ported design, I'm rather learning here. I understand you have some experience with that? I did some si...
|
|
I'm listening near field (2m away) in a small, odd shaped space and they do give fun. The sound is somewhat compressed, lives between the speakers not spreading but on my list is to try to address it: bass modules, supertweeters (anyone selling Tanno...
|
|
Edgar, did you try augmenting Dannoys with ScanSpeaks? I don't know where did you get high order filters and ported enclousers from but it's not on my list. I do not plan to crossover Dannoys but run them in parallel with ULF. The reverb idea is very...
|
|
Thanks Paul, but it's much easier for me to order Scanspeaks 25W-8565-00 than chase that Tesla, which I've just done. I'll try two modules with 2 drivers each. ...
|
|
it was quite awful. I picked rel based on their "reputation". Never heard of Tesla apart from the swasticars....
|
|
With little time I have now, I tried Rel T9x woofer with Dannoys to see if I get anything I want. Not. I tried one T9x, summing both channels, positioned centrally between the Dannoys and fed from the B2 outputs. It produced a typical hifi on/off bas...
|

Spot on on the system surpassing the owner like children surpassing the parent. I did feel that several times, which is probably even documented here, and that was highly stimulative and even transformative. Too complex to understand at a given s...

[quote user="rickmcinnis"]Just noticing this.I have a pair of those VIAWAVE tweeters if you are interested in them.Have no need for them.[/quote]I may be interested to experiment with Dannoys. Feel free to email me the details (version, condition, pr...
|
|
Thank you Paul. The thing is, once you hear that bass, you want more of it. Actually my appetite is even higher now. I've upgraded the XO caps to a higher grade (ClarityCap ESA -> MR + Milflex ) and this decreased subjectively the bass quantity at...

I'm going around with the Dannoy bass augmentation like, as we say in Polish, a chicken with an egg. I posted my problems on DIY audio and managed to get some interesting comments from a gentleman named Art who was kind enough to educate me a bit...

Simulations cost nothing, so I continue my a bit random walking and played a bit more with a PR sub idea, inspired in some way by Romy's la...

I was just wondering if these graphs would tell anything meaningful to anyone. I have unfortunately very low experience with a speaker design.
One problem reported by Romy was a bass integration. The main suspect was the quirky PR phase behav...

And here is the same 37Hz PR box but with added 4th order Linkwitz filter at 60Hz:
I'm confused as adding the lowpass filter gives quite a different phase behavior, without the characteri...

I laid my hands on WinISD speaker modeling tool, which seems to be quite popular and widely used. It can model passive radiators too.
Here are the simulations of my idea of the Dannoy bass: Scan Speak active + Scan Speak passive in the same bo...
|
|
Thank you Paul! Yes, I did notice Romy's tweeter movement, he also described it two posts ago. But I have a different room than him (smaller, dead, close walls, etc). I like the HF a lot, esp. with Ortofon cartridges, but I'm missing some air. C...

[quote user="Romy the Cat"] Elso, I failed
to calculate the very precise size of enclosure necessary to make all the
system work properly. Generally speaking, if you have a very very small
listening room and very up-close position, and if you ...

I recently had a visit by a close friend, who is an accomplished modern jazz saxophonist but a recording/mixing engineer, running his own small studio. We listened to some bass-heavy material on my Dannoys, the bass was acoustic - piano and drums. Da...
