Hello from Sydney Australia

Hello guys, I'm not exactly a total numpty when it comes to audio and home theatre, but I would say many on this forum may consider me one!! I'm professional in comms and electronics, though old enough that we studied thermionic valve theory rather than integrated circuits... Anyway, home theatre for me is the television with a 5.1 system, well, more like a 5.05, and sometimes just a 5. Have a 60" Panasonic plasma, Onkyo 100 w/ch receiver and some Wharfdale Pacific Evo speakers I've had for quite a while now. I've mainly been interested in music, so chose the speakers based on (a) heavily discounted at the time, and (b) sounded OK on a range of music. The amp was also discounted and had a direct mode where all DSP was bypassed, which I like for music. I had some home made speakers (Vifa drivers) and an old Luxman amp (circa 1970) which I moved to a study room... and I still had the speakers I purchased with the Lux amp - Kef Concertos, also of the 1970 vintage. So I put both Kef drivers front-to-front in the one Kef box - speakers in isobaric, and tuned the port (now protruding a bit!) as per WinISD. I drove this with the Lux, but was never happy with how it sounded with music so disconnected it. Years later I've resurrected the Kef isobaric and bought a cheap D class 200 watt amp to drive (potentially overdrive!) it.

Still no good with music, but better than no sub for a lot of movies, so I want to get a bit more out of it now - thinking of applying some EQ, as I'm sure by ear anyway) it has a massive lump in the 50-60 Hz region. Probably wasting time with the old Kef drivers, but a bit of fun anyway....

Recently discovered DSP on a project where we had an EV DSP up front of a road tunnel PA system (evacuation, not music, but we needed the EQ to get intelligibility in a 6.5 km long concrete tube) so thought it may help my sub.

That's a long hello

Re: Hello from Sydney Australia

Welcome and thanks for joining us! Please visit us often.

My first college days speakers were Wharfedales. I don't remember the model, but they were low to mid end purchased in 1967 or so, driven by a Heathkit AR15 receiver. Both long ago relegated to the junkyard.

This is a great place for advice on upgrading from any level to any level. Just give us an idea of your budget. Also, acoustic room treatments can make a huge difference in your system's sound if the aesthetics will permit them.

Again, welcome and please visit us often.

Hug your pet today!

"numpty"? What is that?

Looking for me, just google my username. I have used the same one for most sites for many years.

Re: Hello from Sydney Australia

Hi hjones, I've done a little acoustic treatment that helped quite a lot - just fabric coated 20 mm thick foam on the back wall, and beside one of the main speakers that sits beside a wall. I've got a fairly restricted little space and the speaker placement is compromised to keep everyone happy :-) But no treatment for LF and I know there is cancellation happening in my listening position, though it's a little better after my recent speaker moves (driven by other reasons, not acoustics, though the bottom end improved at my listener position). I did have some free software once that predicted this (response based on speaker and listener location within a given space), though I forgot what it was. Dreamed about LF acoustic treatment but it may be a little too much to be accepted, and I don't know enough about it....
Hi Icaillo, I've already picked up some stuff while looking at some posts - my current goal is to find the best bang-for-buck way of EQing my current cobbled up "sub", though in part hjones may have got me thinking about a couple of things I might do in the acoustic dept... I'm sure I'll still need EQ as the whole thing (sub) is a little low-rent ( I suspect the amp has a bit of a bump in it's response that aids the bump caused to some degree by the compromised sub location (corner). Numpty is much the same as Newbie, except Newbie has lack of experience as an excuse :-)

Welcome to the Home Theater Shack. Nothing wrong with vintage gear. There is a lot of bang for you buck there. Some tweaking is in order but with time and patience, I'm sure you will get it dialed in. Remember the only person who has to like your system is you.

Hello and welcome to HTS.
