I have a long list and try to have a concistency to shape my listening judgments, so I till listen the same recordings from 20 years where I begann to diy cd players (I remember having tweaked more than 30 or 40 units when it costed nothing second hands, had a lot ainly with philips and Analog device chips but noy only... and DACs till 10 years).
I try to include soe references more when I judge them interessant for that purpose, that includes very good and very poor recording or mixing for diferent reasons : cliping, distorsion, confort zone and so on... I tweak to death my dac sources to sounding good in my listening space, EQ old school if you prefer (but I should go active/DSP amp in the next months when learning step will be crossed...)



Let me some time and I will PM you a non exhaustive list and also some more personal asked about female voices...I will be happy to have your feedback tastes as well

I'll see if I can post the info; I bought 4 inch and 2 inch pyramid foam both from Amazon. I didn't want stuffing/fill loose in the woofer chamber because everyone said you need to keep an open path between the woofer and the flow resistor Aperiodic vent. I added the 2 inch pyramids on the removable panel on top of the felt damping. I only used the 4 inch pyramids in the woofer chamber making sure again to keep a clear path. Anything to avoid reflecting sound waves and vibrations back to the woofer should help. In my past life; I had a wife and a nice house with a big workshop. I made many 5 sided boxes back then; ZERO parallel surfaces was the goal to avoid standing waves. I no longer have that luxury so I use pre-made or knock down boxes and modify them to my "exact" needs. Of course, these are all rectangle boxes so we have parallel sides (the reason for felt+stuffing+foam pyramids, etc.)...

Brian Bromberg - Wood

One of my favorite bass players; this on the CD player is a Japanese re-master of the album "Wood". I keep tweaking and fooling around; next on the list is a decent calibrated microphone, stand and USB interface with phantom power and pre-amp, etc.

I seriously think this current combination of drivers is hard to beat in this price range. Again; The SB Satori MR16P (4 Ohm) in just over 0.5 ft^3 closed (about 15 liter) for a Q of around 0.5. The MA Pluvia 7PHD (P7PHD) in my "bread container" and the Fostex T90A up top. The SB29's are now fully broken in. They are really good at regular bass; scary good sometimes! The Satori 9 1/2 inch or ETON 11 inch probably have a better transient response and better upper bass but the SB29 just hammers away at the main bass frequencies probably better than anything else for the money. Hey; 37 Hz f3 in a smallish closed box, 3 inch VC, huge magnet and 22 mm of LINEAR X is very hard to beat in this price range...again; subs still out of the room...

More later; musicians coming this evening for more critical listening; fine tuning ALMOST over!??...(well, most likely anyway...)...

Thanks! We have a disease of sorts don't we with this crazy hobby?; always looking for the next improvement in the pursuit of perfection in every price range!
