Tapped Horn TH-121 build

[ZivkoF]

Very nice!!! One day I will build a nice HT sub like that. Any plans for those tops??? Hey Djlivex, did you finish your Tuba 24's? I see you are in Tampa, I am in Largo and I have always been curious about the BFM cabs.

Hi,

must see if I have the plans some where, the tops sensitivity each is 111 dB @ 1w/1m with BMS for Hi and RCF for Mid driver. All Hi/Mid/Low are with Neo magnets.

TH121 build

Almost I am waiting on more drivers for my 12TB, pm me I will let you know! I am interested in this design and looking at some Faitals for this TH121. I will be building DR250's soon with new Faital 1" HF107.

I think the plans are in the speakerstore.nl site!

 

[djlivex]

Also ZivkoF, would a cone compensating device be needed in this design? Thanks!

Hi djlivex,

Sd/S2 compression ratio = 2,16 : 1 there is no need for cone compensation device. Some inner photos before final painting.

There a couple of plans simalar but they either require 12s or dont go as low or not trap shaped.

I was just curious about the long thread on TH18 with the compensation device. If I use 15mm version can I use Arauco with 5 equal plies? Or just use the 18mm version in Arauco which is about 62 pounds per 4X8 sheet instead of 76 pounds for the BB? Thanks!

SonicXtasy I thought that plan on that site was a copy of the Cobra mid-top 12"/1.4" ? Thanks!

Hi djlivex,

Better is 18mm version in Arauco, and 15mm version Arauco you can use for all internal brace, that is in original plan, the box is not small so 18mm is more rigid

Built like a house!

Ok let me look again I may have missed that it's 15 mm internals, Thanks!

10-inch Mid Neo driver vs 2 x 8-inch LF driver

Equipment plus two FLH

 

[BP1Fanatic]

Man, that setup must sound awesome!

 

[ZivkoF]

Operating Frequency Range.................22 - 80 Hz +/- 3dB
(Referenced to 2,83V @ 1M 1/2 space), Nominal Impedence...8 ohms

 

[BP1Fanatic]

Nice response!

 

[ZivkoF]

An externally hosted image should be here but it was not working when we last tested it.

Nice response!

Hi BP1Fanatic,

I like the sound too, this responce is 1/2 space or 2Pi outside for one, I have two of them and they are colocated as I can read +6dB with SPL meter at my LF with two of them playing. I have them in left and right front corner which might be translated to 1/4 space or 4Pi or close to 1/8 space or 8 Pi inside with room gain and responce is even flater.

 

[djlivex]

Nice! Do you have a response to 100Hz? Thanks!

 

[ZivkoF]

Nice! Do you have a response to 100Hz? Thanks!

Hi djlivex,

Yes I hava from 80 Hz - 100 Hz:

80 Hz.........92,66 dB


85 Hz.........94,79 dB
90 Hz........101,71 dB
95 Hz........106,50 dB
100 Hz......101,45 dB
