TABAQ TL for Tangband

[eljoantonyn]

Thanks perceval ! A very good find. I have visited that site before but didn't pay attention to those drivers ! So, here is that driver.
SB Acoustics SB12PFC25-8 4'' reed cone mid-bass - 8 ohms

Also, what about this cheap tweeter ? Seems good!
SB Acoustics SB19ST-C000-4 1'' Textile Dome Tweeter - 4 ohm

By the way, that driver's (SB Acoustics SB12PFC25-8 4'' reed cone midbass) frequency response graph doesn't agree with the quoted sensitivity. The graph hardly goes above 85db while they quote 87.5db sensitivity.

 

[perceval]

Because you mixed the impedance between the two. You've selected the 8 Ohms.

Look up the 4 Ohms version of the 4" driver. It will also match better with the 4 Ohms tweeter you chose.

Maybe this is of any help: Humble Homemade Hifi - Cap Test

@percevalMy bad ! Here is the correct link. But still, the frequency response graph stays below the 85db line most of the time.

@Spencer Brandsen Thats a very long and exhaustive list. Thanks for posting. But, I have made up my mind to buy that Dayton cap.

If you are dead set on getting more dBs from your speakers, maybe you should look into getting a little pre-amp, that would be able to boost the signal to your amp.

One way to go louder
- try FaitalPRO 4FE35 or 4FE32 - both are quite efficient.... But you'll probably need/want to add a tweeter.
- Add a subwoofer (or 2) to take care of the bass end.

@Jerms
Ok, that should do it ! Thank you for the link.

@perceval
Would it cause any damage to the AMP ?

By the way, here are the tweeter drivers I have shortlisted. AUDIOPUR AMT 40.1 - PAIR
SB Acoustics SB19ST-C000-4 1'' Textile Dome Tweeter - 4 ohm

So, which tweeter is better suited to this application in your opinion ?

 

[Moondog]

I guess that when they already start to look great, they will eventually sound great..

 

[GraphicCanuk]

I agree with Jerms with the 4FE32, mine are plenty loud and I have only one sub. Find it sufficient. I have not decided if I need the tweeter though.

 

[perceval]

And no, a pre-amp will not damage your amp.

Tweeter is better if jumping around, dancing or even cleaning.... If sitting in one designated hot spot, then not so much.

You were talking dispersion , right ?

 

[Jerms]

ok

Yes, one builder of Tabaq uses them in his kitchen and replaced 4" full ranger with Visaton W100S and a tweeter.

Hi guys!!, i'm amazed for this forum, and the work of bjorn and his amazing products. Is possible in any way to get the MJK simulations? I really need it to end up my degree here in Argentina. Best Regards

 

[perceval]

Do you mean the simulations for the TABAQ?
If so, Bjorn shared a lot in his first post PDFs.

If you mean the MJK software, it's not easily done because it runs on old computers only, and the app to run it is no longer available.

You might want to have a look at HornResp. It is actively supported by the owner and runs easily on modern computers.

Thank you so much for give me that info. I give it a try. Thank you again. Best Regards!

It's the best easily available software at present. The Leonard Audio TL software if you can get the off-line download (it's no longer supported) is OK too, though the damping model IMO is a bit off.

I have it too. I read some comments of you guys about the damping simulation of Leonard Audio TL that is not so accurate. But I really glad for your help and for this amazing people that make those amazing software available for everybody.

Best Regards

If I want to use 2 drivers, I'll need to double the crosssection, but what about the port area and length?

Double the CSA of the port. Leave the length alone.
