Good Analog EQ


Looking to integrate some form of analog EQ as a temporary solution until I change my speakers (which is going to take a while).

I can appreciate that adding anything into the signal path is not ideal but I'm wondering if it might be a worthy tradeoff since I have a fairly high resolution system but am not hearing it all because of too much bass (and yes, I have some room treatment already).

If I unplug the low frequency speaker cable from one speaker I get a huge improvement in detail (but of course suffer in other ways), so I'm thinking if I get my hands on some decent equalizer I might be able to improve things.

I use digital room correction for digital sources, but obviously don't want to do this for LPs.

Thanks in advance.

Marchand makes well-respected stock and custom Active, Passive, Tube and Solid State crossovers and also makes the analog WM8 "BASSIS" Bass Correction Equalizer.

Give them a call, I'm sure they can solve your problem for fairly cheap. Here's their review page
If it's just a temporary solution, then just use the digital room correction. No new interconnects, no new power cords and no new rack space needed. The losses resulting from the added AD-DA conversion could easily be outweighed by the increased resolution across the entire frequency range.
Are you handy at all? With what you describe maybe you could get by with a simple L-pad on the woofers to attenuate the LF until you have a more permanent solution.
Thanks for the responses.

PiedPiper: my speakers are Aerial 9's, my room is 14x25 and soundproofed with ASC wall-damping. This sort of traps bass in to some degree, but the issue is that the Aerials were designed with 'thick bass' in mind; they have 4 7' woofers for low frequencies, 1 6" for midrange. They overload my room. My room is also a home theater so the speakers are on the short wall, about 3' from front and side walls. Seating is at 12' from front wall and I can't change this.

The Aerials have downfiring ports. Instead of using the optional stands (which raise them a few inches, I'm using the stock plastic 1" feet). This seems to congest the bass slightly.

Dan: Your post intrigues me because I keep thinking that if I could could attenuate a choice woofer or two it might help. What is an L-pad? If you wouldn't mind describing what you're thinking of, I'd appreciate it.

I'll check out the leads for Rives and Marchand.

Thanks again,

Hello,

I have the Aerial model 6 and I hear what your saying about the bass end of the Aerial model 9. The model 6 is a fraction of your Aerial 9's and the bass is just incredible for the size of bass driver. I have had to do some repositioning in a 12 X 15 room just to get them tuned to my liking. The mid/high frequency reproduction on the Aerials is very sweet to my ears but the bass tends to stand out a bit. I did go with the optional stands and it seemed to improve the imaging a bit. Speaker position with the model 6 is tricky and it took time to find the sweet spot.

I put traps in the corners and some acoustic foam but it didn't tame it much. I originally bought a Velodyne DD-10 to go with them and I have never even turned it on. I was looking to upgrade to the 9's but I saw all those woofers and wondered how I would ever get the sound to balance. I am running a single Mac 275 in the winter, a Levinson 23.5 in the summer and I wasn't sure the 9's would be happy with 75 WPC from 6550's.

I wonder if it would help to talk to the guys at Aerial? I hear they are very helpful and ultimately the most knowlegable about the Aerial 9. I'm running purely 2 channel and cant stand the thought of messing with the signal. The fewer things in line from the cartridge to the speaker the better.

I have to tell you that I sat in on a demo of the Model 9 in a room approximately the same size as yours and they were fantastic. It was a completely different set of gear and it took a bit to get them setup. They had the optional stands and the sound was fantastic. I know they model 9's have incredible potential but ultimately wont work in my room. It sounds to me like you have ample space; I believe speaker positioning and the Aerial stands will really help.

Good Luck,
