Attention Lowther owners DX3 vs. DX4

anyone?

Hello Bob,
I currently use DX4s in my Beauhorn Virtuoso cabinets. I have no comparison experience between DX4's and DX3's. I suggest you contact Jon B Ver Halen @ Lowther USA 708 660 9312. I have spoken with him over the phone and he was most helpful.
My ( used , bought here ) Beauhorns came with DX4's 16 ohm. I found a new un-opened pair of DX4's 8 ohm @ a nice price which better matched my Wavelength 300B & 45 amps. Allow your DX3's to break-in.
What amplifiers are you using?

It would be very interesting to me to hear the AERs.
I agree with your assessment that the Lowthers are dynamic! I love them!
Tho, I have no experience to judge them against any other driver in similarity.
I will ad that the DX4's list @ $2295/pair USD

Isochronism,

Thanks for your reply. I will contact Jon @ Lowther USA for his take. I was also looking for owners who have used both drivers. My amp is a yamamoto 2a3's tubes. BTW the AER's are just as pricy as the DX4's.

Hi Isochronism,
Tube amps seem to love higher impedance speaker loads.I`m surprise your amps match better with the 8 ohm load rather than the 16 ohm load.Is it that your amps are 8 ohm and don`t have a 16 ohm tap? just curious, which of your amps do you prefer with your speakers?I bet this system sounds really fine.
Regards,

Charles,
Both amplifiers have 8 ohm fixed taps only. I probably prefer the 45s a bit more.
I usually switch from one pair to the other every couple of weeks.
I actually never tried the 16 ohm pair.
With the speakers rated at 106 db I get plenty of volume. My Doshi Pre has a slight bit of volume when the dual attenuaters are fully turned down. I have had the volume up fully a couple of times with the 45s on quieter music and there was no breakup at all.
It was pretty loud, tho!! I am in a small apartment.

Thanks Brett,
You have such high sensitive speakers, you need hardly any gain from your preamp for good volume levels.My speaker is a 14 ohm load and sounds better at my amp`s 16 ohm tap compared to the 8 ohm.Bet your amplifiers would also sound excellent and really sing with your 16 ohm drivers in play.That`d be a fun comparison between those two different drivers.
Regards,

Charles.
I purchased the Beauhorns before I had their chosen amplifiers, tho I knew what I wanted for them which was Wavelength. ( I was using my Heathkit SA-3 with 4,8,16 tap available) I found the Doshi before the amps. I then found the 45s. I was happy! The 300b amps came available shortly afterward and HAD to hear what they were about. Happy again.
I have a pair of JBL 4550 (which is the model # for the 2x15 bass cab.) along with matched and mounted HF fiber horn and driver, all original. I plan someday to bi-amp both pairs of amps when I move.
To sum up... that is why I hadn't tried the 16 0hm version, if that makes sense HA
