Best ported enclosure for a stereo integrity?

[ssmokeyy]

Warranty is a funny thing. I know a long warranty is more comfortable but I have been told a higher quality part dose not need a warranty. If its built correct and uses known quality parts it should last longer than us. I know big names use speaker parts for the amps like jtr and other oems.

Here is the website for it. https://stereointegrity.com/product/sql-15-series-2/
It does look like the same driver u found. Thank u trying to model it. I dont chat on avs anymore but over on avs they say to do 5-6.5 cubic box. Seems kinda large on the 6.5 size.

Let's see what the answer is.

That driver you have picked is nasty for home use. It is not suitable at all for ported alignment. Its response is classic for an in cab automobile driver in a sealed box, and not home audio.

You are wasting your time with that one.

You need to pick a different driver. I have lot of good home designs on file. You absolutely do not want that driver. Also it specs a not totally honest as some number are incompatible with others. AVOID, AVOID and AVOID!

Agreed. Believe me when I say that I’m not the one challenging what I’ve read in the books. I would very much like to reconcile what these guys new school guys are doing with Dickason and the other authors

Those new school guys can do whatever they want, but any speaker box they build is still subjected to the laws of physics which are practically immovable.

Yes. I agree. I’m not remotely challenging this! But suggest to somebody like T.V. That his subs might not be obeying the laws of physics and watch him meltdown.

It looks like a competition car sub. I have the ht version and it gets really loud for a lower wattage sub. But it’s discontinued would had been better. Dayton has multiple good drivers that’s the brand I almost went with .

I'd just refer to him as Tom V as in SVS?

Yes, Dayton RSS series subwoofers are nicely priced and excellent drivers. I have been building high performance enclosures using them.
I strongly recommend the RSS-315HF and RSS-390HF drivers which I have been using. If someone follows Parts-Express suggestions for box designs and dimensions, there should be excellent results. With the absence of proper box design software and some knowledge about Thiele-Small parameters, a prospective buyer should discuss with Parts-Express people about the aimed low frequency response. A different box size will give a different low frequency f3.

Yes, Dayton have a lot of very good drivers that make excellent subs, and I have a lot of designs on file ready to go.

Witch dayton subs do you recommend that can do sub 20 hz? It can also be other brands not just dayton. I have no problem changing some drivers. I really want something that can stay around that 5 cubic box ported.

RSS-390HF has less Xmax than the other few I see but maybe lower distortion? Ultumax is closest to mine.
Wish I could build another diy , but the old one I thought needed more bracing but no more rattling since I took the receiver off top of it. Not tested it loud yet since I switched rooms for it.
I’d have to get flatpacks since my freind who helped me cut the wood last time vanished because his waf . and I don’t have Space for another 15” sub. Right now it may be out of budget though . Mdf is so heavy , ..

Im kinda shocked that tlsguy is saying si sql is not a good driver for home theater. So many reviews, gsg audio uses them, so many people. Past that what does everyone think about the new Dayton Audio SS15-22 15" Signature Series DVC? If not this has anyone tried the new ultimax v2 and how did it turn out?

not sure why it’s so pricey , ?
There’s probably hundreds of threads on it.
https://www.avsforum.com/posts/64273287/how can it only be 28 pounds with that big magnet? It looks like my ht model with higher power handing , Xmax . If specs hold up.

There is more nonsense than fact out there about subs. Stop fixating in getting to 20 Hz. That is a massive mistake. In general those are extended bass alignments, which sound bad. The quality of the bass is much more important than the extension. I avoid extended bass alignments as a rule. A sub that extends to 25 Hz or so, is absolutely fine.

I have quite a few designs on file, which I will look at.

 

[highfigh]

Wondering what ported enclosures have been made and what seems like the best for 20 hz and below. Right now I'm thinking 5 cubic box with 20 hz slot port tune. Power is 1200 rms from speaker power. What have the si sql been doing and like?

Why do you need sub-20Hz frequencies?

Random box volume and port selection isn't the way enclosures are designed, as TLS posted. It's all based on what the driver is capable of, not what someone wants it to do.

That is a powerful driver, but it is following current trends. The trend is to higher sensitivity and more output and away from extreme bass extension. In my view this trend is correct.

That driver you mention looks to be a good powerful driver. The ported F3 is 29 Hz. This trend is correct as with room gain you get to 20 Hz.

My speakers are TL designs with two 10" drivers in both lines. F3 is 27 Hz calculated, but with room gain it is flat to 20 Hz, and I don't have equipment that will go past that point.

That stereo integrity you referenced does not even have an honest specification. When you try to model it Bass Box Pro, comes up with a bunch of red circles saying the numbers don't match up and are impossible. So I could not even model that piece of junk for you.

If you are going to be sensible, I will model you a serviceable and workmanlike sub from Dayton drivers.

I will be leaving shortly for Rochester MN for a prolonged and intricate procedure tomorrow.

If you are going to be sensible and and forget the bilge you read online, I can design a very serviceable and good sounding sub for you. If you are going to chase phantoms, then I'm out.

Do u think I could get a good out come with a dayton 18 with either the ultimax v2 or signature series?

Ultimax are only for sealed application. I am leaving now and will model the signature series when I am better.

I do think that you would be better off with two subs with 12 or 15 inch drivers, rather than one though.

perhaps specs lied? On avs Ive seen people use that sql . I found one thread here but the op seems to nEver finished building it.

Subwoofer Driver: SI SQL-15... any experience?

Thanks to @Pogre and his Good Deals thread, I started looking at Dayton Ultimax Drivers... but something rubbed me the wrong way a bit. Pricing, performance... Can't really put my finger on it, but it got me thinking. So I looked around again at a bunch of the usual suspects that I've kinda...

Looks like a more expensive version of my old
stereo integrity. I wish it had 1000rms I could had got a bigger amplifier. The 24” version got real power handling mine was just an entry level produced model .

 

[ssmokeyy]

I have 3 of them in sealed getting 1200 each. They sound good. If I didn't have this null I want to fix i wouldn't be changing anything. I will probably have to sale my psa double 15. Not enough room to keep it.
