Second floor apartment? Really? When I have people ask about my subs and find out they’re in an apartment or connected condo, I tell them my subs come with eviction notices. Good luck with those and the fight to keep them. When I first turned on 3 sealed 18s for my wife, I said if that was too much vibration, we could put rubber feet under the couch. She looked at me and said, “you most certainly will not, that was awesome.” And I’m sure people ask why do you need a car as fast as a Bugatti. If you have to ask, you just don’t understand. Luckily, our subs are a heck of a lot less expensive for their capabilities than someone buying an exotic car.

It’s not quite a sealed 24 but it might wreck something. Lol! I kid. Looking great so far.

Mr. Ricci, can you design me a ported box for the SI HS-24 with no more than 8 cu.ft. of enclosure volume? And can you tune the port to 12Hz please? You’re the bestest! Thanks Josh. Happy Holidays guys! Thanks for hosting such a magnificent and informative site!

Now you hold on. Don’t mess with my fake sounds in space because I love said rumbles. And can you imagine how boring a space movie would be without sounds in space. Duh!

Me thinks you’ll fit in just fine here. Welcome.

Space physics! Duh!

Geez, just wall it off and get a rotary sub already. Now that is some bass headroom!

This is what I make my wife and kids wear when watching a movie with me. And it’s what I wear when doing any work around the house or shop. https://www.amazon.com/gp/product/B00NKSMPZW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 David

And then whatever number you come up with for dollars or hours, double or triple it.

Haha. No to a ported 24. I don’t want to deal with moving and shipping huge refrigerators.

For the mixing/studio room silly. But hey, most theaters only do 30Hz and up so maybe a single ported 24 would be plenty.

Infrasonic, can I get your friend's address so I can send a 24 so your friend can learn to mix the feature films CORRECTLY.

I often tell people with most speakers, the speaker will get unhappy before you but with mine, you’ll get unhappy before the speakers. My speakers are JTR 212s with compression drivers/horns. I couldn’t go back to regular (non-horn) speakers now. But the CDs have to be smooth and detailed, which so far has meant higher quality compression drivers.

You should have seen the reaction to my room at T.H.E. Show Newport in LA with my 60” TV sitting on top of a 24” subwoofer flanked by a pair of JTR 212 HT-LPs sitting on top of a pair of JBL 15” midbasses. They were going to leave because of the TV but made the disgusted faces when seeing the 24” sub. Because physics fails when a 70 lb magnet-motor moves a 24” 1.3 lb cone. Lol! Interesting story about the doc. I’ve had plenty of similar conversations and it usually doesn’t go very far if they’re “audiophiles”. And frankly I’m not that interested in fighting those ingrained beliefs. Life is too short for those with closed minds...about any subject.

MemX - that cart is not designed for stairs and I expect would quickly break. Like LilMike mentioned, you want an appliance dolly like you’d use to move a refrigerator or washer. And then strap horizontally around the dolly just below the handles. And then strap vertically around the sub and appliance dolly support plate so the person below the dolly can help lift the sub going up and down.

I have some experience moving large subs unfortunately. Get yourself a decent hand truck (not the stair climbing gimmicks) and a ratchet strap (endless or continuous would be best so you don’t have to deal with the hooks). Just strap the thing down vertically and then you can pull up with the truck handles and the other person can lift the sub or the bottom of the hand truck to go upstairs. Or pay someone to move them for you, which would be my vote. Lol! EDIT: would probably recommend a second ratchet strap vertically to strap the sub to the bottom support tray, which would then allow the lower person to lift the sub more easily. And rubber coated gloves grip smooth veneered surfaces well.

Funny that many in this forum are among the very few in the world that could actually faithfully reproduce such a recording. Really wish we could get a quality recording of one of the launches. Would be phenomenal.

Thanks for the PM Kvalsvoll! Responded.

Sorry to take it off topic with the sound velocity meter but I really didn't as I've noticed what you described above as well. Why does a 12" midbass have more impact than a 6"/8" midbass when played back at the exact same sound pressure level? I've asked multiple times, at least on AVS and I haven't ever received a satisfactory answer. I was hoping measuring the velocity would help point me in the right direction so I can understand this phenomena better. If you have ideas on the physics, I'd love to hear it. And I'd love a pointer to a thread (couldn't find the one you referred to) on a velocity measurement kit to build or device to buy. Purchase depends on cost as well as if that will help me understand this size difference better. Thanks.

Sound velocity meter? I'd love to measure sound velocity as well as pressure. Tell me more please.

You mean I don't have to warn people anymore like I do every time I put in John Wick? Lol. I bought Kubu but haven't watched it yet. How To Train Your Dragon is also one of my favorite demo scenes.

Or dig a hole in your yard or a field. That's what I have planned when I work on some speakers. Either that or rent a boom lift for a weekend.

The speaker is coming along nicely. And great looking veneer and finish work.

Are you doing this for the community in general or thinking of starting up Ricci's Subwoofer Emporium? Those would be some impressive though big to build, handle, ship etc.
