Can I use this Hornresp Value for Sim another Driver?
For Spud Diy Can I use this Hornresp Value for Sim another Driver?
Danley sound labs is introducing a new tapped horn called
TH-SPUD
I think this is an interesting concept and so I tried to model a diy version.
I'm thinking of using two B&C 8NDL51 drivers. They have a 7 mm xmax which I think should be enough for my small living room.
Planned layout +/- 120 x120 x 25cm:
Respons graph in Akabak with quarter wave resonating tube at 65Hz and 60Hz low pass:
Hornresponse input:
So what do you think? Will it work? Any design faults?

Now I Sim with Dayton
Now I Sim with Dayton SD215a-88 Xmax= 6mm Prices 30$
Dayton Audio SD215A-88 8" DVC Subwoofer
And another Sim Dayton RSS210HF-4-8 Xmax 9mm Prices 105$
Dayton Audio RSS210HF-4 8" Reference HF Subwoofer 4 Ohm
The Black Line is SD215a-88 The Grey is RSS210HF
I so confuse because the price are very different between two model.
If i want to go with Dayton Driver Which one I should go? Why?

The reference line sub has a bigger voice coil, handles more power - power compression will be less. It also has more xmax and a more stiffer cone. Also it has demodulation rings to reduce Le and Flux and give a better behaviour when working at the xmax border. It has a cast frame which is more stable and all of the materials are of higher quality than the low-cost dayton.

At CES this year, Parts Express had their 8" subwoofer on display. It's really nice - very similar to the TC Sounds Epic 8.
The driver is on sale for the next three days, and based on it's specs I'll bet it would perform well in this box. A real steal for under $100. It's part number 295-459.

I think your right.
If I remember correctly the original drivers were close to the same efficiency.
Yep and I posted earlier about the RSS210 being preferred based on published specs: http://www.parts-express.com/pedocs/specs/264-854-tang-band-w8-740p-specifications-45675.pdf

I just saw this new Eminence driver PE is now selling. Part number 290-4008 Eminence 8" High Excursion DVC Subwoofer 4 Ohm Per Coil
I wonder how that would work in this design?

Hi Y'all,
Here is my attempt at it. I had to find a place and size (very slightly reduced) for S3 that would approximate the expansion of the horn. There will still be small errors between the Hornresp horn shape and the actual horn. You can play around w/ the flare to see how much difference it makes (Con v. Exp v. Par).
Regards,
