Quad HS24's to BHS24's

I've been a LONG time lurker of AVS. Can't thank all those that continue to give advice to us rookies. This is an ongoing project and I'm starting to realize the end isn't in sight after all.

My theater space is about 15'x45 open to another 30'x45". Basically a wide open basement kinda sectioned off but not closed off.

My quest was to duplicate the sound I had in my car 22 years ago, inside of my house. Wow, that was very hard to do because my basement eats bass for breakfast lunch and dinner smh. I went through many different speaker companies and never satisfied. Long story short, it wasn't until I stumbled onto AVS and after calculated research gave SI a try. First rendition was a couple 4cf sealed HT18's and that was a satisfied second base hit (baseball). Then I tried four sealed 10cf (without stuffing which I did add) HS24's and that was a bases loaded grand slam for me! I was more than satisfied. Just 1 of them actually felt like an earthquake!

Now I'm redoing the entire basement which includes running dedicated circuits to each of the four CV-5000 amps, one for each of the four BHS24's. Here's a pic on the theater section before I started tearing down sheet rock. I weight lifted for a couple weeks and went to pic up the BHS24's personally. Always good seeing Nick, love his passion with his products and customer service, why I'm a 4x customer. More to come as I make progress.

I was going to post a pic but I don't have that option available...🤔

How do they compare to the HS24 in terms of sound quality?

I sold the HS24's and in process of sanding and re-staining the enclosures before I install BHS24's.

The HS24's are very fast. I was under the impression the bigger the cone the slower the driver. That's NOT the case with the HS24. I was told by a pretty knowledgeable subwoofer seller (post on AVS) that control is relative to the motor strength and why the HS24 sound so controlled and compliant. I'm guessing the BHS24's will be even better.

I was more than satisfied with the HS24's. I only upgraded to the BHS24's for the strongest motor that was best matched for my application. I go for the 5hz signals (amp response limited) which are bigger waves than 15,20hz etc. I wanted the most headroom as far as travel and most ulf tolerate, if that makes sense. I went with four to spread the load and soundstage AND having the space to fill.

I would trip the breaker with 2 of the amps at moderate levels but when temporarily riged a circuit I quickly realized I only needed one HS24. Since I already had the 3/4" 13ply double layered and quadruple baffle birch enclosures built, I figured I may as well fill them with the most capable. Maybe I'm a little ocd when it comes to my toys, I definitely over did it. However, I'm so looking forward to firing up each BHS24 and amp on its own circuit.

Between kids softball, cheerleading, baseball and football; other house stuff, working and traveling; theater rebuild will take a few months to complete. I will give intiial subwoofer sound impressions within a couple weeks. I'm really looking forward to hearing how they sound!

If waf is an issue and you are testing up drywall, why not do build in ported aka architectural large low tuned subs? Move a wall forward and they will be concieled.

1. I like the sound, feel and experience of 5hz and up not highest spl.
2. I want to keep same amount of floor space.
3. The sealed enclosures are already built.
4. I'm focused on building a larger projector screen wall and 14-16 more enclosures for a system I'm trying to future proof.

I never thought this hobby would get so intense and I so consumed with it smh

I'm just glad you're built like a body builder and made the BHS-24's look like a 30 lb speaker when you loaded them up in your car. For me, picking up a 150 + pound 24" woofer is not a whole lot of fun but you made it look easy.

And technically whoever told you that motor strength equaled transient response needs to be corrected. Transient response is dictated by inductance, not by motor force. Read our paper that we have hosted/posted for the last six plus years by clicking this text.

Omg you're such a nerd, in a good way 😆
He said something like that but what I got out of it and paraphrased was, whatever you're using in your ingredients made a stronger more capable motor for my application...

Umm, like 30lbs, yeah right. 150lbs is still 150lbs 😅 Like industrial strength military grade weight 😂

I'm working on pics but most of the time I login from my iphone and it's not giving me the option of uploading pics.

I am running an HS24 MKII right now and I am kind of afraid of using the MKI I have sitting here along with that, thinking that would be waaaayyy too much. Can't imaging what 4 BHS24's would sound like!

Hello AVSForum, excuse my infrequent post. For some reason I can't post pics from a iPhone and it's been all business while siting at a desk or laptop. Just know the BHS24's sound shockingly big and at this point would like to get a professional audio tune up as a whole then have this system reviewed as a whole...

I'm doing as much of this basement rebuild myself, paying for what I need to be in code and will pay for what I don't have completed by 2017 NFL preseason-ish. I took down sheet rock, part of the ceiling as well as added plumbing and electrical. It's an open basement divided into 4 sections and I'm growing the theater section from 15'x45' to 30'x45'.

The breakers and wires were installed first and I couldn't resist the urge to fire them up. I'm again speechless! Extraordinary! Wonderful! Amazing! Insane! Are all adjectives that come to mind but do not truly articulate the amount of ULF production, except maybe Earthquake... The windows appear to flex.

I have a projector hanging from the ceiling and during certain scenes from Battle LA, 9, Batman Under The Red Hood etc etc; the picture becomes indiscernible. I think I could shake my house frame apart from nails backing out the way the windows flex, walls vibrate and things fall off walls and counters. It's endless bass. It's A LOT of bass but the best part about the BHS24's are how articulate and quick they sound and behave.

Again, these are in 11-ish cf sealed boxes tuned flat 14-20hz before I have things tapering off at 23hz with a sharper drop at 42hz and a 48db lpf at 75hz. I tuned it to the liking of my ears then measured and adjusted. I like to keep my ears tuned to the really low stuff from our earth's movement and what's produced in movies which is played 95% of the time. They sound incredible!!!

Aside from the long weeks repairing avionics, kid extracurricular activities and home improvement projects, I'm also working on 14-16 AscendAcoustics Seirra LUNA bookshelf speakers and the amplifiers to drive them. I went with 2 MX-A5000 amplifiers after flirting with and deciding ANTHEM's weren't in the budget yet.

The BHS24 sound amazing...!!! Every time I hear them seems like a new first time experience. They do a exceptional job producing ULF. I almost feel guilty for buying 4...! 1 is enough, 2 for anesthetics but 4 in sealed enclosures are overdoing it. 7hz hitting you is an experience and if you can't hear it initially just keep listening.. You're actually tuning your ears with repetition and it's pretty smart to stay in tune with the earth and her rumbling...

3-4 projects will be complete in 2017 😁
More to come...

Ha....What I forgot to mention was that my HS24 is in addition to a pair of Submersives and a pair of TC LMS Ultras. So running another HS24 in my not too large 3000cuft room might be a bit much.....in an apartment with neighbors too.

Have any of you guys heard both a HS24 DIY system and a Funk Audio sub? How do they compare?
