Product Details

FaitalPRO 4FE35 4" Professional Full-Range Woofer 4 Ohm

FaitalPRO's 4FE35 4" professional woofer has exceptionally flat response from 90 Hz to 6,500 Hz, both on and off-axis, and features a 91 dB sensitivity due to a powerful ferrite magnet. Distortion is reduced through the use of a copper cap to create a demodulation circuit in the motor.

Great for use in compact professional line array speakers, the 4FE35 is also right at home in home audio, personal audio, and car audio applications. It's also ideal for fixed installation applications as a midbass, midrange, or full-range speaker. Made in Italy.

FaitalPRO 4FE35 4" Professional Full-Range Woofer 4 Ohm
FaitalPRO 4FE35 4" Professional Full-Range Woofer 4 Ohm is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Still breaking in, but so far, so goodBreaking in at the moment, but seem to be opening up little by little. Have them high-passed at 200Hz which is where they start to get nice and flat, and well above the resonant frequency. Plenty crisp on the high side. This is part of my 2nd open baffle project, of which I have included a picture. I have them coupled to 4 - 6.5" factory buyouts that seem to be perfect for open baffle. So far, I'm liking the results, but look forward to fully broken in drivers. In case you would like to know, I am bi-amping this 2-way system with a JL Audio 500/5 auto amp, and am using it's electronic crossover circuits at 12db Butterworth slope. Will experiment between that and Linkwitz 24db slope. I have it in home and DC power source is an HP Proliant server PSU that gives up 65amps on the 12 volt rail. According to the numbers, the amp requires around 30 amps at full load, so plenty of head room. Head unit is also automotive based and is Eclipse CD-8445 with 8 volt low output stage. So far it has fit together quite nicely.

Rated 5 out of 5 by from Good sound and reasonably efficientI bought these for a 1984 Jeep. They fit with some modification. I used grilles I had that matched. The sound is clean and more accurate than most auto sound speakers that are similar size. The efficiency is a little better that typical for their size. I used them with a 2x15w class D amp. The combination works very well. I use an iPhone as the source.

Rated 4 out of 5 by from Nice Driver!i needed a 4 ohm 4 inch driver, and this fit the bill pretty good. It is pretty efficient, so gets loud without too much driving it. Decent bass for a full range unit.

Rated 4 out of 5 by from Great supportI had a blown driver but did not know the impedance. Tech support helped me figure it out and the replacement driver is installed and working. Bass is a little more than I would like. But, adjusting on the pre-amp worked fine.

Rated 5 out of 5 by from Great first impressionI was looking for full range drivers for a small portable boom box and liked the efficiency and price point on these units, so I bought a couple of them. I was immediately impressed with them. I would assume they perform better in a line array, but I only had two. I did hook them up in a series to get a feel for a multi speaker design and liked what I heard. I finally just hooked up one for each channel and added a small subwoofer and had exactly what I was looking for in an inexpensive small(ish) boom box that I would enjoy listening to with many different types of music.

What speaker grilles fit these that are less that 5.5" outside diameter?

Unfortunately we don't have any grills that will fit over this speaker that are less than 5-1/2" in diameter.
