subwoofer help

[Stoner51]

I have a budget of avout 350 and am looking at maybe a DIY 12 dayton tiatnic with 240w plate amp cost about 280 shipped. Then I got to looking and the bic h100 12" with 500 w amp sells for 280. What would be the advantage to building my own, other than the satisfaction. Anyway your input would be appreciated. My room is 18x12. It is our living room so looks and size is somewhat important. I have a Denon 2106 Bic acoustech center and bookshelfs(to arrive Tue) and some cheap surrounds I plan on replacing also. Mostly I watch movies but don the occasional music. Thanks Steve.

Steve....how handy r u with saws? It really does take abit of skill to DIY....esp. if looks is important (WAF). No sense making your spose mad...lol. However there is certainly a satisfaction from doing it if you have the yime and possess the skillz!

I am fairly handy with saws and a router. However I want to understand which will be better. If they are the same price and the acoustech is better than it makes little sense to DIY. I have all the equipment I need to make the box. Just want to make sure it is worth the time investment.

That's a tough one, and a toss up. The reason being that Titanic 12" driver deserves a larger amp (500 w/rms). A ported design would be tough to engineer perfectly, as the Acoustech is. The difference is you get a much better driver with the Dayton DIY design. The logical build for the Dayton would be a sealed design, which requires a larger amp to reach similar spl's.

Dayton has some new, better drivers called Reference. They sell the high output, and high fidelity (get the high fidelity - RSS315HF-4). They have lower distortion numbers and lower Fs compared to the Titanic.

RSS315HF-4 Specifications: *Power handling: 400 watts RMS/700 watts max *VCdia: 2-1/2" *Le: .95 mH *Impedance: 4 ohms *Re: 3.3 ohms *Frequency range: 23 - 1,000 Hz *Fs: 23 Hz *SPL: 89 dB 2.83 V/1m *Vas: 3.00 cu. ft. *Qms: 3.00 *Qes: .52 *Qts: .44 *Xmax: 14mm *Dimensions: A: 12-3/8", B: 11-1/8", C: 5-3/8".

If you're really good with a saw and numbers, you could build something extreme like this and get incredible bass with a capable amp and Dayton driver:

Buckeye, looks cool -- two tuning points? Are the plans for this posted anywhere?

I feel confident that I could make that box however not so confident about the price tag. So if I build a design like the picture I could get away with the 240w and if I want to build a sealed box I will need a 500w amp, am I following you. I had an idea to make a box to set where one of the endtables in the room are and to make a 3/4 in plywood top with some oak trim to take the place of the endtable. And I can stain it to match the rest of the living room wood furniture. Are the specs for that box posted anywhere? I might consider looking into that. I think I could still put a table top on that. Thanks for the info.
