I know many would view the two frequencies as similar and perhaps of little consequence, but I have my reasons.My primary, driving objective for wanting the horn to produce sound faithfully to at least 90Hz is that 90Hz represents an ideal crossover ...

Hello:I would like to ask this forum for advise.I picked up a very simple and cheap RTA and decided to use it to listen to my speakers. It is 1/3 octave RTA, so I know Romy will say it is useless. It may not be very useful, but I start with nothing s...

What I have is a subwoofer made by ACI; no information on the amplifier used other than it uses a two prong power cord, no ground. When I hooked it up to the APS 2000 I got a very loud pitched hum. Taking if off the 2000 and plugging it into a...

I used a set of 2-way near-field monitors and a decent sealed commercial subwoofer in a study room that was quite enjoyable. Mostly listened to FM. That room was not much more than 3m x 3m with lots of alcoves, slanted ceilings and a thick nylon rug....

If you look that Jeffrey Jackson’s midbass horn then you can see two pillows stuck into the horns belly. Let presume that the pillows were placed there in purpose. So, here is homework for people who would like to flux their horny mussels: what is t...

I think I wrote In the past here, if you like the 10” Tannoy, why not try the 12” or 15”? The ones with rubber surround are not so good in my view (from CPA or DMT series as they have very restricted midrange) but the cloth surround Tannoys are wort...

I'm also concerned about the range, but I believe that in using an appropriate driver, I may be able to achieve a target range of 40Hz to 400Hz.One reason for my wanting to achieve this range is precisely for the purpose of not wanting to have a 4-Wa...
