    The Perfect Solution for Home Theater Bass Optimization Here!

    Hey gang. This is a sweep of my 4 Sealed 4cuft SI HT18 Subs in my room. There is absolutely no DSP or eq applied. One sweep is a pair front another sweep is a pair rear and the third is all 4 together. I’m trying to determine what my cabin gain looks like. Clearly I’ve got a huge kick above 30...

    FS: (5) SI HT18D2 v1 Subs in DIYSG Sealed Cabs and Amps- Separate or Package

    I have 4 very well built and finished DIYSG 4cuft Sealed cabinets loaded with the SI HT18D2 V1 drivers, duratex finished, Neutrik connector and wired in series. This set of 4 subs is serious LF content and levels, with extension well down into the single digits. They rival or exceed many ID...

    Great question. The 88A uses Dirac Live. Much more accurate and automated right? Perhaps the 4x10 without Dirac would also do the same? Sent from my iPad using Tapatalk Pro

    The Perfect Solution for Home Theater Bass Optimization Here!

    Start with a 2x4 HD. Much better than standard. Several reasons. I would recommend running Multi Sub Optimizer (MSO) with it. Amazing results. You can also upgrade an HD with software firmware plugin for Dirac down the road. Sent from my iPad using Tapatalk Pro

    I need AV advice

    The Denon X4300H is at a great price now for Black Friday. I’d consider running it as a prepro, you just lose balanced XLRs. Sent from my iPad using Tapatalk Pro

    AV Receiver Question

    This is true. They used to have full 7.1 inputs for SACD and the like. Made integration really easy and gave lots of flexibility. Not sure they have this now. Sent from my iPad using Tapatalk Pro

    Dual Cap 4000s on the way. We will leave it there. I self admittedly have a problem, and Jeff Permanian is my enabler [emoji6] Sent from my iPad using Tapatalk Pro

    AV Receiver Question

    That makes zero sense. Amps plug into the pre outs and just leave the powered connections open. You may need to configure some of the other powered outputs for their optional content (ie sub2 May be a atmos channel). I know this doesn’t help but it doesn’t at all sound right.

    Auro-3D Listening Evaluation on a Denon AVR-X7200WA

    What are your thoughts on integrating 3D with a low 7’ ceiling? I plan to run the bottom surrounds somewhat lower than ear level and the surround heights will be at the wall and ceiling Intersection pointed downward. VOG just forward of and middle of seating? Sent from my iPhone using...

    Auro-3D Listening Evaluation on a Denon AVR-X7200WA

    I plan on picking up this receiver as a Pre Pro. I plan to run a MiniDSP 2x4 with Multi Sub Optimizer to take care of my sub integration. It will probably work better than the Audyssey. I have 4 subs. Sent from my iPhone using Tapatalk Pro

    What New Stuff Have You Bought? If You Care To Share Thead! :)

    Picked up a JTR Cap4000 LFE. Maybe a second! My 4 Sealed DIY SI HT18s served me very very well, but now it’s time to get down to serious business!! Sent from my iPhone using Tapatalk Pro

    Lower Level Media Room, All LFE propagates up?

    Understood. I’ll be doing some research. As the room is finished, and not a bat cave dedicated HT (as much as I’d love it to be some day) I can’t change the walls for floor but I can get that ceiling dampened. Maybe some wall treatments and bass traps as well. Sent from my iPhone using...

    DIY Stereo Integrity HT 18" V2, with baltic birchwood enclosure flatpanel kit.

    Price on an HST 18 is 6 and change shipped. That’s not bad. The 24 is under 1100 shipped. That’s an impressive driver in a sealed box. A pair would be truly incredible. At those prices it changes the high end subwoofer game. Sent from my iPhone using Tapatalk Pro

    Marantz Unveils SR7012, SR8012 AV Receivers and AV7704 Processor with Alexa Skill

    I watched a short video on you tube on it. I think that would do the trick. Just as long as I can manipulate and fine tune the “auto” settings esp on the main to sub xover. Sent from my iPhone using Tapatalk Pro

    Marantz Unveils SR7012, SR8012 AV Receivers and AV7704 Processor with Alexa Skill

    Thanks! I’m going to seriously look into these. Last question, Audessey Pro, will it allow me to customize for example Mains to Sub crossover slopes and freqs? What else might a Audessey Pro option and kit bring? Thanks guys. Great info!! Sent from my iPhone using Tapatalk Pro

    DIY Stereo Integrity HT 18" V2, with baltic birchwood enclosure flatpanel kit.

    They were completely removed from the website. I read on AVS that someone there exchanged info on Facebook and he said they are gone and no longer available. Maybe that was Private Messaging. The V2s were supposed to be indefinitely available, whereas he told everyone with the DS4 that it was a...

    Lower Level Media Room, All LFE propagates up?

    No HVAC down there. Main and second floor has it for AC heat is hot water baseboard. Any recommendations on what insulation to buy that will be safe with recessed lighting and wiring and will act to dampen sound? Sent from my iPhone using Tapatalk Pro
