Re: Doc modding Marantz imperial 7

More spouting of bollox (probably). I am currently playing with my second pair of 30cm cubes with two 6.5 inchers in it. Doped up firing is connected to the amp. The down firing one is unconnected - a bit like a passive radiator (swear word round these parts). I am having a play with it because curi...

Re: UK Hi-Fi Show today & tomorrow - Daventry

I have seen a few notes on other forums and they all sound (no pun intended) disappointed , shame. :mrgreen: I have seen them too, mega buck systems not sounding very good. Shows how important the interaction with the room is. Rooms really are bastard things. Doc used to say semi omni works with th...

Re: Doc modding Marantz imperial 7

Typical room gain (other room gains are available :grin: ). Starts at approx 300 Hz. At 50 Hz it is 4dB on the graph. Not sure why I am posting this other than I found the graph and wanted to plonk it somewhere. Might be helpful if one is designing a pair of speakers for a typical room and ears (you...

Latest crazy experiment. Put both cabs right next to each other :shock: https://i.imgur.com/1kbNmW2.jpg You would be forgiven for thinking this is a stupid idea. At least one member here listens to their cube's like this (Hans?) Anyway, I really really like it :dance: No stereo separation of course ...

Re: Doc modding Marantz imperial 7

It is a real shame I don't use my four 12" drivers :cry: The options were open baffle or infinite baffle. I don't want to get into the necessary EQ required to make them work in OB. True infinite baffle (mounted in a wall or floor with the backwave having at least 10x the Vas of the driver) was...

Re: Doc modding Marantz imperial 7

Have U heard the isobaric clam shell ? Yes Peter, I used to have my doped 12 inch drivers in clamshell isobaric. It worked really well and was never the issue with those drivers, the issue being the Qts and Vas were so high I couldn't get the box small enough to be domestically acceptable without a...
