Re: SI 24HS D2 quad

I had a few minutes to do more listening today. I played Battlefield LA and tripped a breaker during the helicopter scene when the Marines are first deployed. I didn't realize it had so much ultra low frequency in there. First the lights deemed and a quarter second later I heard a pop then lost power. The thing is the 24's sounded very clean and looked controlled. Matter of fact, I have no idea how loud it was. My focus was on the movement of the surround around the drivers. I'm truly amazed at how clean and quick the SI 24's are!

Re: SI 24HS D2 quad

You need four more to cut down on some of that distortion.

Re: SI 24HS D2 quad

Do you have them on a dedicated circuit? Or is other equipment sharing the circuit?

Re: SI 24HS D2 quad

4 of those beasts must have outstanding output, but it seems like you need to upgrade the power that you have feeding them!
Any more incidents like that 1?

Buying more cheap stuff to get better sound is like challenging a dragon with a pocket knife.

Re: SI 24HS D2 quad

It's super late here (literally it is 2:15 AM as I'm typing this) but am I reading this correctly - 4 (four) HS-24's in one room? Holy !!

Re: SI 24HS D2 quad

This project has taken longer than I expected but it's well worth the wait! I started with 60"x60" sheets of 13ply baltic birch plywood. It took 14 sheets but I paid a great woodworker to build four 30" square enclosures. They're 29 3/4" after all the cuts etc. Sanded them and stained but I have to resand and stain once I get them in their open 40'x20' room in the basement. Each side has 2 layers of 13ply which comes out to 1.5" and the baffle has 4 layers which comes to 3". I didn't do any bracing but can always add later if needed. The builder used kreg screws in the coners to attach each peice, glue and pin nails. It looks really awesome, well, his craftsmanship and workmanship. My staining skills need improving but next time I'll use a sprayer.

Nick is a top notch stand up kind of guy that has obvious passion in what he does. My background is sonar on board submarines and now avionics on aircraft. I've been around the best of the best and when you have a standard of excellence, it doesn't matter what the product is, it's of quality. From training with and dropping off Spec Ops from my boat (submarine I served on) to test flights with aggressive pilots, I mean when I say Nick of SI would be in the crew. It doesn't matter your role, you live with honor and a standard of excellence because failure isn't an option!

I picked up the 4 monsters personally from Nick in January and wow they're intimidating to look at. Plan was to use the 2 cv-5000 amps I bought and drive one 24" driver from each channel. Well I just ordered 2 more cv-5000 amps because even though they sounded great getting 2500 watts in their 10.25 cubit feet boxes, they sound even better using 5000 watts. I had to experiment and hooked up one 24" in the brigded mode. That 24" laughed at it and I ened up damaging my circuit breaker trying to make that ONE 24" monster tap out. The whole house shook from only one driver! I obviously over did it by purchasing 4 but us Texans like everything BIG!!!

I'll post more later but I totally get why most everyone that buys one of these 24" peices of art go silent after receiving it. We're in bass heavan lol

More to come, but I'll run a seperate circuit for each amplifier.

Re: SI 24HS D2 quad

This is absolutely amazing to read and just wish I could hear it. It also is inspiring me to get my HT18 done in my small theater area so I can experience bass like that(well not like that but maybe on the edge of the same realm).

Re: SI 24HS D2 quad

cowboyup, thanks for sharing. Reading other peoples' impressions is about as close as I'll be able to get to these phenomenal drivers, but I really enjoy seeing crazy guys like you take on a project with FOUR of them, at 5,000W each. Please do keep us updated as you make progress, I'd love to see them finished and in place.
