I will not prefer the vented enclosure as it has a over damped response in the low end and can cause listening fatigue. As this is a quick simulation, there is a scope for improvement by carefully adjusting the driver position, vent position, vent tuning and stuffing of the enclosure to bring it to critically damped region. I have 15 years ago used a JVC 8" woofer having similar response and i was never able to tame its low end because i did not have any simulator at that time and did not know where to go looking.
Yes it's just Ahuja Frx 12 playing, they were playing better in some sequences, in my treated room, than MA Silver RX6 & our FM @Nikhili accompanied me.
Awesome sounding. So much fuller even though captured with a mobile phone.
Honesty Frx 12 is excellent mostly in the mids, (I'm listening to all oldies Cds and Hindustani classical collection all over again) it'll be benefitted by both Super tweeter and LF drivers ; the higher sensitivity of the driver makes up for the need of tweeter so you can get away without a HF support. But ideally you'll have to support it with a LF driver, again a OB LF would be a better option, I'm confused as far as the driver choices for LF in OB goes, as you can see I've left a place for LF driver to be added later.
I feel my room is a bit small for the driver, @19ftx14ft, so I'm overwhelmed by the HF effects because I sit in the middle of the dispersion field. A rather big room would have been better IMHO.
I was running with Dirac filters over my room treatment. Dirac helps a lot in getting the sound right. I have tried with Taga SW 10 and Pioneer Subs and Marantz SR 7010 in 2.1 mode but the sub and OBs never gelled seamlessly. Playing OBs alone was much better IMHO. That's why I'm looking for good dedicated OB LF drivers.
I played the OBs with 3W 6j1 based tube amp and I did not need to raise the volume pot above 30%,the driver sensitivity is amazing. At a point of critical listening I was able to make out a difference between Holding the CD player in hand and placing it on the Rack. (I know many will be grimacing at this, but I could hear a difference).
Yes I use Kodi mostly, though I have got Jriver, I'm pretty used to Kodi since Rpi days. Kodi plays dsd as well, and it's very cool. I'm using HP compact PC /Kodi with i5 and 250 SSD, currently Tidal is what I'm mostly stuck to.
Precisely, this has been my experience!
Looking at the FR only as it's a over damped response Can you hear the notch at 1645Hz? You have built using winisd hence asking. Check for port noise by putting your ears close to port. You will gain by adding some damping at the port using foam or something similar.
You can use AS 15 200 on an plain open baffle or in Ripole way if you want it to be compact. I am happy with Ripole as it supports the AS15 by lowering its Fs thus enabling its capability as a better LF driver. I suggest you keep the LF separate to avoid transferring vibration to 12FRX.
Your speakers looks great! Share some more photos of it showing around, if that is not a problem for you.
Correction: The system Q is higher and it's a under damped response. Will do a advance TL simulation and check if the response can be critically damped.
I think I remember you did this some time back too for the same driver and the size came out to be enormous for an apartment in Mumbai.I simulated a MLTL with the Ahuja - 12FR driver and got this very good response. Its way better than the ported enclosure design with a critically damped response with a smooth -6dB roll-off from 50Hz. Will sound great in this setup for sure with well balanced low-end. Also the size is much smaller than the ported design and can be installed in Mumbai type homes.
So what you are building finally?
