  2. I saw this in IG earlier, but I scrolled so fast I didn't realize it was a whole new design, I thought it was a slight redesign of the existing model. Stats are insane as "usual". Re of 0.26Ohm thou? Recommended to run two series drivers off a single X4L channel (which is running in bridged configuration)? BL²/Re is 1700, but the data sheet says 1600 and that T/S params are not fully accurate for the M-drive type transducers, if I understood that correctly, but holy cow. Has as much surface area as two 21" drivers. Does 5KW. I'm just not fully understanding the sensitivity ratings. Either way, 94db at 0.5V is pretty impressive for a 2.5kg moving mass. Do I want one? No, I want 10.
  3. ha ha I think I saw your FB post in speaker freakers
  4. I was just wanting to post it! They've been working on them for a while, changed the motor a lot

    Combining bass and subbass has provoked many interesting debates (at least I think so with the ones I have read over the years). If I summarize properly, there seems to be a general pattern. It seems that first a distinction between vibrations and spl is characterized and challenged to distinguish properties of bass and subbass. Much of this depends on the listening environment (e. g. The room) and the person (e. g. Different body types with different resonances). Afterwards of that dialogue, different theories and experiences of impulse waves VS sine waves are exchanged. Many state that large motor, heavey surrounds, long travel are excellent for producing subbass - usually sinewaves. To produce impulse waves, many state the opposite of the above - lightweight, stiffer surrounds, less travel, etc.. Having a driver produce both very well is an interesting conversation that has been dominated by money and physical space available. Producing both simultaneously can be a difficult/impossible task depending on the drivers and cabinet designs. My own personal thoughts - having had the luxury of experiencing many different home theaters which have had various designs with minimums of 8 18" drivers in the room - I have found that with the space and power, I do prefer large amounts of impulse based driver systems/configurations that supposedly do better with bass VS subbass. With enough of the impulse based drivers, the subbass reproduction reaches needed spl levels I preder while delivering the bass and midbass I enjoy - all "cleanly" . With systems that had high excursion drivers that theoretically excelled at sinewaves, the sound of bass and midbass just wasn't my preference. However, without enough of the defined "impulse style" drivers, the subbass lacked in creating the vibs and sensations I also enjoy. So, like most things in life - your mileage may vary - there are many variables and options. Hopefully we all can chase what we enjoy and then figure out how to stay happy once the chase is over
  7. I’m new, comin’ to this party late but... I think someone covered this but 15dB boost @ 58hz suggests a room mode - sound waves canceling each other at the mic’s pick up place Anytime time I see boost more than 3-4dB I get concerned especially below 50* hz. Many years ago someone said or wrote using EQ: “think of yourself as a wood or stone carver - remove what you don’t want - the peaks.” W/that mindset you will very slow to boost at any frequency. *as frequency falls, when boosting, power demands increase 3-5 fold YMMV thanks for reading this far, hope this helps.

    Did you really just compare two overpriced 13" subs to a 32" sub? I thought about doing this a while back, but I decided to not go that route, as I could imagine that the resulting phase issues would be severe, thereby working against myself (lowering system sensitivity and efficiency). Probably takes a lot of testing/aligning to get right, just like using multiple subs with different tunings (although FIR filters could help you out in the latter scenario).
  9. My first post on this website. I’m struggling to connect the two previous replies w/all that came before. and... Infrasonic opened a question on surround back speaker positioning that I’d like to ask here if that’s ok. Otherwise please suggest which forum page to post upon. Either way I’ll follow w/my system details in a separate reply. Tony

    They seem to be sealed boxes won't they work fine into the 100Hz+ range? I have seen infra subs that are very narrow band using tuned pipe enclosures arranged in an array of varying pipe length to cover a frequency range not possible using a single pipe.

    Btw i wanted to know what the forums members think of combining bass and sub bass. I really think not one sub can reproduce all the bass and sub bass info. 20-50hz a certain type of size and design works and 5-20hz another size and type of design. Ill repost some rew graphs when all eqd and calibrated. Will love to compare and have some input

    Hehe. I also dont have grill for the 32inch. Let me tell you i have jl audio f113v2 x 2, the room stopped responding at around 18hz. With the 32 i can go down to 8hz infra in 170m2 room and still feel it. Swopping my jls for the 21s in hope that ill get higher spl at 20-30hz range

    Got a link? few companies called Ascendo but non of them seem to do 32" woofers.
  16. I've got a 2400 cu ft room and I'm considering two sealed subwoofer cabinets using the RF T3 19. I want the best possible transient response. That made me look at sealed boxes. I've seen Josh Ricci's testing carried out back in 2015 in sealed cabinets. The EBP suggests it's possible to mount them either sealed or vented. However, Rockford Fosgate explicitly state on their website "Do not use sealed box" as it's been optimized for vented. What will the disadvantages be for running them in sealed cabinets, poor efficiency, shorter service life, overheating? I listen mostly to music, but having these obviously they will see some Home theater duty as well. EDIT: OK, so I've looked around some, and see JR is running his 8 in dual opposed pairs in sealed cabinets, 4.5 cu ft per driver. My first question remains. I had originally planned to get two T3s, but it turns out I'm only getting one. I know this will lead to cabinet resonance. In addition, I had planned on wiring them in series, and now, since this is a single one ohm driver, and that it could go as low as 0.8 ohm, I'm wondering if it's an idea to put a resistor in series to up the resistance the amplifier will see. I would really appreciate any comments.
  17. Guys please get hold of ascendo audio and ask for a test unit on one of their 21inch subs and or their 32\50 inch monsters

    Been hifi and cinema enthusiast for 10 years with experience in commercial gear. Interested in what diy and modders can do to gear and also their opinion regarding some lesser known brands. Anybody have experience with ascendo and their subwoofer and infra sonic gear? I currently own their 32 inch infra sonic and was blown away what this 32inch can do compared to jl audio rel and bowers and wilkins high end gear i also own. I live in south africa so very small enthusiast community. Im currently looking at the 21inch offerings but the frequency range compared to db1d or fathom f113v2 doesnt seem up to spec. Any input will be appreciated.

  21. The 24's from Harbottle Audio that are being discussed in other threads just might help ripole get more attention. Ve series would be the perfect route. 32 inch subs would make them popular for sure. Efficiency for home use would not be a problem. Small intimate spaces would enjoy them too.
  22. Have any of you tried the 2269H in sealed enclosures? I have three JBL 5628 subs (ported@25h with dual 2269H) but in my upcoming theater I'm trying to save some space in the room and was considering using the drivers in a shallow and sealed type of enclosure. (Google Procella P18 - a clone basically). I know I will give up output below ~40-50hz, but given that I have six drivers and almost unlimited power for them, could this work? Room is ~3000 cu.feet.
  23. Thoroughly appreciate everything up to this point!
  24. Thank you for the time and effort over those 10 years. Still kinda struggling with the reality of complex induction and oem vs consumer availability for drivers. I want deep and clean. HT/Music/Automotive/Nature sounds for sleep. Will eventually reach out to Harbottle Audio for something underhung and nasty. Data-bass helped me understand why that is hard to find in the consumer market. Also understand why the price is north of what can be bought in a couple of mouse clicks.
  25. As far as testing goes. There is nothing happening right now and for the immediate future. I've had to turn away a bunch of companies and projects since this time last year and I'm still sitting on a whole summers worth of testing from well previous to that. I'm not planning to be done completely, but after 10 years my priorities and other life goals have shifted and I can't find the hundreds of hours to put into testing, and publishing every year, like I once did.
