I agree with Zaikesman. I do own a pair of VS VR4jr's and I would also be sure to add lead shot and spikes to the speakers before making any other changes to control boomy bass. If possible set these speakers out into the room further or even fill the front port with foam to improve the bass tightness.
Tube amps to control VR-4jr bass?
Hi,
I recently bought a pair of VR-4jr (I think it's MK 1) from a local shop in Indonesia. They should be delivered to my house within couple days.
Does anyone know what amps were used during the design stage to voice this speakers?
Currently my power amp is Conrad Johnson MV-55 50W EL34. I do not know if this amp would work well with VR-4jr since I could not do a home audition. I bought the speakers because the soundstaging and image focus was excellent and the speakers overall sound very dynamic although I had problems with bass during audition.
During audition at the dealer yesterday, I paired the speakers with the following amps; all configured with Cary SLP-98 preamp, speaker cable is single wiring and source was Cary 303 CD. No lead shot and spikes were used :
- Cary V12 EL34 set to 100W ultralinear. The bass is very thin and not enough amplitude.
- Rogue Audio Stereo amp 90W KT88. Bass was very boomy.
- Genesis Integrated with KT88 60w. Bass was not boomy but not enough punch
- Cary Cinema 2 200W stereo
I also tried bi-amping Cary V12 for the upper part and Cary Cinema 2 for the bass. The bass was still boomy but not as bad as with the Rogue Audio and I prefer not doing bi-amping to keep things simpler. I also heard other speakers to compare in the same room with similar setup. Vienna Acoustics Mahler: Bass was big but maybe too much. Vienna Acoustics Baby Beethoven Grand: Bass was good but soundstage sound small. Room size was 4.5m x 5.5m x 2.7m (15 x 18 x 9 ft).
Can you suggest several potentially good amp to match the speakers? My concern would be with controlling boomy bass I heard during audition. I don't hear very loud music. Mostly female vocals, jazz and classical orchestra. No deafening heavy music. Would a 90-100W tube be enough since I have problems with both the Cary and Rogue audio, both of which have power rating around 100w? I prefer tubes, but am open to SS amps if necessary.
I am interested in VTL MB125 monoblock with 4 EL34 130W ultra linear at 4 Ohm ot 100W at 8 Ohm or VTL ST150. My other alternative would be VTL MB185 monoblock with 6 6550 230W ultra linear at 4 Ohm or 165W at 8 Ohm. I cannot do a home audition since most dealears are located 600 miles from where I live.
Thanks in advance.
