Mark goes at it again... just bought a PL700/II!

Doesnt matter what color they are when you're putting 300 watts to em..

 

[Wheel-right]

But they holes in the back, lets all the sound leak out, in the wrong direction. I'll stick with the JBL's. Besides I already got em.

Those are nice....ever heard a pair of L200's?

 

[Wheel-right]

Nope, L100's only, they got holes in the front too. I think the 150's were about the last of their unported beasts. I see they are remaking the L100's again.

I always hear a hollow sound from ported speakers, just me I guess or maybe because I grew up listening to the unported things.

Tje 200's sound mighty fine..

dose it really matter? ported vented bassreflex what ever you want to call it should not matter since bass is omnie-directional it should sound the same if it on the front rear or a side. only thing when it is on the back you can not put them on the wall.

 

[laatsch55]

Not always...my speaks bass comes out the back...

 

[K-5BLAZER]

yes that is true sound can from the rear of a speaker. unless I have misunderstud some things I have read mid and high frequincies are directional but low frequincies can be persived from all directions

When D9's are outlawed , only outlaws will have D9's..

BAN ASSAULT BULLDOZERS!!!

That's it Andrew. We had a D 9 go rogue in Gillette a long time ago. Wiped out 23 cars and 5 apartment buildings. A disgruntled coal miner.

Well shit! How about the British guy the sprayed down city hall with manure...

A class act, that was..

Part 12: DCP circuit installed and tested. I don't have a frequency generator (but I did buy a cheap-o Chinezy DIY from FleaBay) but I found a different use for the Audacity application. Funny- the PL400 rebuild I did a while back had the DCP cutoff at 17Hz, is that a bit too high?

 

[laatsch55]

Depends on your speakers I suppose. But some source material goes below that so you might get some nuisance trips...

R138 is the front panel sensitivity control- shouldn’t this be *audio* taper?
Is this another world famous PL typo?

Hi Mark
The ones on my 700B measure quite linearly.

You from the east coast?? Seems to me sealed speakers were popular on the east coast while ported speakers were more popular on the west coast. you hear the expressions " the east coast sound" and "the west coast sound" I am from the east coast and loved EPI's but then heard ported and just like the bass they put out......

 

[VSAT88]

I have heard it this way. You have the British sound, The East Coast sound, the West Coast and............ the Klipsch Sound.
