Re: sonosub planning phase

Oh heavens to betsy! I had my hopes up for a pair of Aura MR 18.4 s but they havent materialized so Im turning to more readily available drivers. Of course, since a sertain someone turned me onto the mr18, ive been aflicted with a similar loss in perspective I suspect a number of first time DIY ht sub builders have. I got used to models showing 115dB at 15hz and its hard to go back to looking at models for the Dayton Reference that hit X max at 200w and only yield 105dB at 20hz. I would have to imagine my mind would be blown quite thoroughly with a pair of those, but why take the risk of conntracting upgradeitus?

SSSSOOOOOO.....

Let us revisit the begining, shall we?

What I want: Smooth response into the infrasonic, effortless output, safe headroom, agile sound(good transients, Im tired of mud), to scare the guests.

What I have: Picked up an EP4000 off craigslist for $225 new in box, room wired for subs in four locations, strong desire for epicness.

Uses: equal parts HT, music and gaming. I do listen to a lot of D&B and dubstep, so deep, HT like bass is desireable, but i also listen to cello rock and blues, so a bit of a higher tuning could be good, maybe?

Heres what Ive been considering: I might convince myself spend up to $350/driver, putting stuff like Q18s and such in range. Im also thinking about multi-tuning either with dual ports or by sealing up the enclosure entirely. Comments on that? That would seem ideal for a good mix of high output club-level music crank-fests and brown-note-hitting movie viewing, no?

Thanks for all the info thus far. The more I learn the happier I am that I didnt jump into this any faster.

Re: sonosub planning phase

Is box size an issue?

Re: sonosub planning phase

Not really, I had gotten pretty comfortable with the idea of two 24" 'tubes 6ft tall. I do want to run a pair of whatever I build so theres a limit somewhere. Ill know when its reached.

Re: sonosub planning phase

A 24" tube 6 feet tall would allow for a net volume of 17 cu.ft.

Here's what a pair of Titanic 15's would do, each in 14 cu. ft. tuned to 14 hz. Each sub would get 550 watt and output would be 117 db down to 13 hz, plus any room gain that you'd get.

A pair of Titanic 15's is $467, shipping included.

Re: sonosub planning phase

Ill have to look at distortion info on the titanic. It seems to take a little more effort to get it to dig as deep as the reference, but output does look superior.

Any thoughts on using two ports tp vary the tuning? Or would i be better off having seperate presets in the bfd for music and movies?

Re: sonosub planning phase

Have a read of Grahams multi port tuned subs, he would be able to answer any questions regarding this.

Re: sonosub planning phase

Thats a very interesting project. Pretty much along the lines of what im looking to do. Llt is starting to loose its sheen for me now that im reading more about the impact they seem to lack and such. Easily varying the tuning would seem a good thing to be able to do.

Re: sonosub planning phase

Sorry about the unfruitful Aura 18 suggestion.

I would think that with dual 15" or 18" LLTs, you'd have enough headroom to spare, and sound quality will probably depend on placement and room treatment more so than type of sub. Dayton, Fi, and Mach 5 are about the only large driver manufacturers on the market for those on a budget, eh? Dayton can really come in at a nice price when you factor in shipping, and many have been pleased with their products, so I'll be looking forward to your build thread.

Re: sonosub planning phase

Ill definately have to do more reading on multi-tuning. I think that will be key in giving me the sound(s) i want. In the meantime, Ive got a lot of modeling to do on a few drivers.
