It seems likely that the bass towers would affect the sound in that situation, perhaps eating some sound waves? Are you going to listen with them in and out or the room, or just leave them there, no matter what?Best regards,Paul S...

I liked your previous post . A week ago I repaired old Telefunken tube radio (Single EL84 with array of alnico speakers ) with FM band and I'm listening to classical public radio for whole week. Not even once I had desire to turn on "big" system I'm ...

Hi all,In my experience it is VERY hard to get anything resembling realistic bass from a vented box, particularly with a Q of around 0.9 or 1. There is too much stored energy in the system and too much overhang. The best bass I have heard...

Romy - as it turned out, the 'crapped off bass' that you refered to was in part due to the consumer pre-amp I was using.I attach an mp3 from a recent session where I recorded using a DAV BG1 into Mytek stereo96 converters. In making the recording wit...

The bass units meant for ported loading of cause, I might measure the Fs later on but I am not sure that I would need it. I don’t have any of T/S characteristics for my bass drivers. The driver behave as I needed them in prototype version and it is a...

Well, thanks for the heads up, I was planning on giving myself a PP2000 for Xmas, now I have to re think this.I used to have a 10Kva Isolation transformer and a DIY sort of Line conditioning system with a bunch of nice 4.7 mfd caps between Positive ...

That suck, it was two days as my playback shine at full glory and then my bass amps blew up. It has heavy noise from one channel and sounded like it self-arouses like crazy. It turned out the one of PS large caps got burned and stopped to filtrate th...

Yes, if you are at 40Hz first order then you are with regular dedicated LF channel and tone is certainly a subject. The entire definition of ULF channel inkstand or LF channel is that ULF channel has no tonal information. It is very same like use twe...

Big R, Fascinating as always. but here's a question: If a quiescent current shift of 5mA makes such a huge difference, then surely there is something very wrong, either with the amp or one's perception? I say this without having any experi...

I did find replacement tubes OK (online), just not locally, like I had hoped. I have now recieved, installed and tested all new tubes but the 6N6Ps, which have been delayed in St. Petersberg by Christmas mail jamb-up. ...

Got last night the last bass drivers for MiniMe’s bass sections and put them all together. Even thought I still have problems with MiniMe uppers channels (the Fostex F120A drivers are still hatching) but the bass sections turned out to be very good. ...

The weak bass of low-power SET amps is well known. I don't think anyone would disagree.Some reasons:Simple low power, especially with 93db speakers (try with 106db like Yorkville LS1208 horn subwoofer it might be different).SE output transformers hav...

Recently a German hifi magazine started measuring bass responses of power amps under load. Unfortunately I only had a short glance into the article at a railway station book store, so I don´t remember what exactly they did, but the winner in the 5K i...

Thanks for your comments, Romy.Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems ...

Vasyachkin, if this is still relevant:I've tried dipole bass and dipole mids with horns mid/highs in my system. If anything, dipole works the WORST for the bass and here's why:It does not load the room with bass pressure (or bass sound). ...

It is commonly known about the relation between the ultra high frequencies and lowest frequencies. The extended reproduction of highest frequencies ”improves” the lowest octaves and makes perception more susceptible to bass. The phenomenon is well kn...

Have you considered the opportunity of raising your upper bass HP crossover? How high do you plan to use your mid bass horns? If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use your upper bass horn to p...
