Different from the ones I have built before, I haven’t give much importance to the low extension of the enclosure. When you send 2 Watts your response will differ from the graph given below. If a constructor didn’t want the hassle of tuning them, they could simply build this modification into their speakers by reducing the throat width from mm internal , to 80mm. It was when we moved to a detached house in the sticks, and our ‘normal’ listening level increased substantially, that the bass output became excessive. Placing the port on the front may require some additional absorbing material to be placed inside the rear chamber. The cone should be sized depending on the room acoustics, type of amplifier, preferred listening levels and personal tastes.

Different from the ones I have built before, I haven’t give much importance to the low extension of the enclosure. High efficiency and an easy to drive speaker impedance where my criteria, so I looked for full range drivers, to avoid crossover circuitry. For a trade off in efficiency, the FEE offers some benefits Depending on your taste you can close some of them in order to fine-tune the speaker to your room or other devices you use in your system. Nothing is perfect, and Horn speaker design is all about juggling with compromise, but I think the fe166s presentation of the Daleks is excellent.
This seems to be a general characteristic of rear-loading and I think you can expect it with most of these drivers. I have tried to build this enclosure as small as possible but again it may not be the best as far as WAF is fe1666e it never is. When you send 2 Watts your response will differ from the graph given below.
To keep the footprint to a reasonable size, I decided to make the speakers tall, as even with an ordinary enclosure, it would be dead space above. The result of the mouth placement, smooth folds and smaller footprint lead to the overall appearance of the Dalek. If a constructor didn’t want the hassle of tuning them, they could simply build this modification into their speakers by reducing the throat width from mm internalto 80mm.

Feel free to build your own Daleks. I don’t much like the aesthetics of the Fostex enclosure either. Enclosure Plans [ kB pdf] note: In the low frequency band of this driver, in a certain frequency band, the amplitude stays the same as you turn on the volume. In our previous home, a city apartment, where there where neighbours on all sides, up and down, the Daleks gave a useful bass boost, like ‘loudness compensation’, at lower listening levels.

Comparing it to the older FEE, it doesn’t extend as low in the bass but the upper mids seemed a bit smoother if less detailed. This is not necessarily needed with a voltage source unless you think the bass is a overdone, which is not likely. ve166e
Yes, there is a peak in the midbass, which can be smoothed with fibrous wadding in the chamber and horn throat. The side panels foatex require a little more ‘twist’, and the lower front panel would need to be modified but the remainder of the cabinet remains the same.
This isn’t a dramatic tool which has an enormous effect on the sound, therefore you can play with it confidently. The FEE has a limited xmax 0. Because of the high sensitivity I can say that the atackness will also stand out and will easily be driven with low powered Class A amplifiers. As described in the previous page, these enclosures elevated the FEEs to a highly recommended status. Flatter overall response and less moving mass.

What you should expect: Like Dick’s, the EQ network looks to take some of the upper midrange out as it can get tiring over time, but you will instantly notice the 10dB improvement in the bass. However, AJ-Horn is a reliable software and there is no reason for me to doubt it. If you are looking for more or louder bass than you are getting with a FEE and you’re willing to give up a little top end detail, then this is a good choice. The cone should be sized depending on the room acoustics, type of amplifier, preferred listening levels and personal tastes.
The absorbing material I prefer is white fiber and I am planning to cover the panels of rear chamber with it. It will take more power, has a 96dB sensitivity and if the specs don’t lie, it also has the greatest excursion of the bunch. As a result a F3 of 65 Hz came out of the simulation.
You can understand from that graph that, no matter how you load this FEE, you may not receive a certain band of frequencies. Placing the mouth ce166e the rear of the cabinets, and venting from the sides, means the room corner and cabinet sides can be used to extend the effective horn length and mouth size, resulting in smoother response and deeper bass.
