SB Acoustics SB20FRPC30-8 sealed cabinet

[HenkelmannAudio]

SB 8" full range driver is very impressive! Just finished these last week. 30L sealed heavily damped cabinet. Finished in Teakwood, internals, front and rear baffle in baltic birch.

Dedicated stands are still being built but these actually arent to bad either.

I think I had KEFs back in the day that had stands like those.

Can you define heavily damped, the dimensions, and "impressive"? 😉

 

[HenkelmannAudio]

All cabinet walls are braced and lagged with 3/4" denim insulation. The cabinet is then filled with poly fill.

I don't know what lagged means. And will have to Google denim insulation, don't know what that is either 😁

 

[HenkelmannAudio]

Lagged- all internal cabinet surfaces covered in 3/4 denim insulation (insulation created from recycled cotton felt)

I don't know what lagged means.

lagged; lagging. transitive verb. chiefly British slang : to transport or jail for crime. chiefly British slang : arrest.

So somehow ~permanently attached such as stapled, glued, nailed, etc., in this case.

would you mind sharing the sound characteristics of this speaker ? l bought the similiar driver and looking for suitable cabinet to house it.

Lagged = lined.

l bought the similiar driver

and this driver, and it's spec's?

 

[Malm7913]

They look really cool.

How's the bass?

 

[HenkelmannAudio]

The bass is very good. Tight, controlled with the correct timbre and reverb for my taste. It does drop off really quick below 55hz but thats expected in a sealed cabinet. The overall presentation of the soundstage and imaging is what I'm used to and extremely similar to the Jordan Eikona in my main system. With the 8" driver the dynamics are effortless and they fill the room with ease. I have tried a lot of full rangers over the years including most Mark Audio drivers, Jordan Eikonas and Seas FA22RCZ. Although all these drivers are somewhat simialr, for the price of this SB driver it is easily the best Ive heard!

 

[Malm7913]

I'm in the process right now of tinkering with the FA22RCZ. But the SB20FR seems like such a good deal...

Thanks for the reply
Looks like we have similiar experiences. l am using Markaudio 12p and Eikona at the moment and l like both .
l bought the driver after listening to the youtube posted by spcjpnorg.

One thing I like about my Eikonas is they have a warm presentation to everything they play. A relaxed, lush sound that once you are used to that, a lot of the other drivers start sounding harsh and edgy. The SB 8" does have a more dynamic and foreword sound, but its not over done. They just sound detailed, precise but never harsh.

 

[planet10]

But with some top end issues that drive me crazy. Same as the JX92S.

[bako62]

Please elaborate on what drives you crazy?

 

[planet10]

It is evident in JX92S, Eikona, Alpair 10 (the original), much less in Alpair 10.2, almost cured in A10.3.

Perhaps something to do with the big 10dB lump rising up at about 10kHz.

I have not heard the JX92S but have tried most Mark Audio drivers except the MAOPs and I prefer the Eikonas. To me they sound the most natural and pleasing. Having said that, I could live with all the others and unless A/B testing differences are minimal. Not to mention give any driver couple weeks of listening time and they will sound "right" to you before you know it... Hence "break in" time recommendations from manufacturers....
