And the speaker power amp retails for around $1500. So driver is $1600 and amp is $1500. That is only around $900 left for box design and construction and profit margin. Unless he can obtain better deals on the above pricing than is advertised. Still sounds like quite a reasonable price if $4000 is correct. Given that the speaker power amp is only available to OEM's and is an awesome amp, this could be challenging to replicate in DIY (at that price).
I'll post pics in the Deep Sea Sound thread.Thanks for posting. Can't wait to see your pics of this beast!
It was great meeting and talking with you. I liked the SI HS24 driver so much when I heard it, I decided to start a company around it. I believe it is that good and I'm glad to hear others agree.
ShadyJ, thanks for stopping by the room again today and thanks for donating your two test CD's to me to use at my house. That one track that dropped down to the single digits was just nuts. I took a video of that track and I'll upload it after I get some rest and am able to post it tomorrow. Even though it looks and sounds impressive we were still only tickling the 24's at 1" or maybe 1.5" of total cone travel even at the deepest moments in that track.
Glad you enjoyed it. By the way, here is a post I made with info about that pipe organ track, but I will just repost it here:ShadyJ, thanks for stopping by the room again today and thanks for donating your two test CD's to me to use at my house.

A funny bit of trivia for anyone reading this thread: the guy who made the SI24 driver literally developed nausea after repeatedly listening to this tune on his own product, and not because its a bad tune, but because of the physical effects of such powerful sustained deep bass!Saint-Saëns: Organ Symphony, excerpt from second movement (Poco Adagio). The infamous track 1 from Hsu's demo CD which they send with some of their subs models. Here is a description:Quote:WARNING: When playing this track for the first time, lower the volume, as your woofers may be at risk. The bottom octave of this recording may damage vented or planar loudspeakers. (The opening string passage should be quite soft.) Boston Civic Symphony conducted by Max Hobart, James David Christie, organist. Two AKG 414 ORTF cardioids, about the third row in Boston’s Jordan Hall, spring 1983. This was one of the last times that the Jordan Hall organ, already showing signs of serious asthma, was heard in a public performance. [Micha Schattner]
Here is a spectral analysis of one of the infrasonic passages:
As you can see, a massive 16 Hz note, produced from a 32' organ pipe, a CCCC, meaning its a C note four octaves below middle C (middle C is 261.6 Hz). However, it is such a clean note it does not sound as thunderous as one would expect, but when it hits it gives the song such underlying presence. I will add it is a very beautiful recording. You can get the recording from the Boston Acoustic Society, or you could just buy one of Hsu's subs.
Thanks for the graph. It is a huge sustained note focused right at 16 Hz. And yes, having fun with that note one one of David's Deep Sea Sound 24" offerings literally made me feel sick after playing the track three times in a row.
ShadyJ, your two demo disks are nuts.Before you get carried away with the track again, you should think about taking some dramamine- that might help with the nausea. Perhaps that is an accessory Dave can sell with the Marianas, dramamine pills specially formulated to prevent bass sickness; it does fit in with the 'deep sea' theme of the company name!
Okay Nick, I think you've had enough time to rest up. I know there's others just like me waiting to see this video you've mentioned!...lolShadyJ, thanks for stopping by the room again today and thanks for donating your two test CD's to me to use at my house.

Here is the crazy bass track on the DSS (Deep Sea Sound) 24:Okay Nick, I think you've had enough time to rest up. I know there's others just like me waiting to see this video you've mentioned!...lol
Yeah I realized that I uploaded the wrong video so I edited the post accordingly. I'm uploading the pipe organ track video right now. It should be live in less than one minute.Great video! But that's not the pipe organ track, that one is called Bassline Terrorthon. And that sucker is plunging down to the single digits, probably one of the few things that we could play which could cause visible cone movement with the 24. Here is a spectragram of that passage, as it descends in frequency- note my spectral analysis program does not draw below 10 hz, but you can easily see there is a lot of energy in the single digits after a certain point:

By the way, I found your thread at data-bass.com about your DO HST-11, that thing is awesome! The amount of displacement you are getting from those woofers is amazing. I can't believe there there would be a subwoofer anywhere in the world that could beat it for the performance/size. Really nice work on that one!
