Hello,
Hope you are doing well, I just joined the forum because I am just starting a new project.
I got a DIY speaker based on JBL D130, LE175 Potato Masher and XO N1200. Enclosure is big, with a vent in front (but no port).
I got the set after auditioning because I saw potencial and because I need very high sensitivity speakers for my tube set amplifier.
The speaker sounds nice but not really flat. So I wanted your opinion about how much this can be improved.
My current setup is: Turntable Luxman Pd290 with Benz Glider L, SUT Cinemag 1254, phono EAR 834P, SET amplifier valve 71 with tango transformers, and mentioned speakers.
The speakers do some things really nice, it s clear in guitars, voices, piano... I really like the potato masher, the speakers gave a lot of detail and resolution in the mids but it's laking on the high and low frequencies (for instance drums). Jazz and acoustical material deliver with great sound. I am also not sure if the low mids are very correct in this setup. The 101db have gave a lot of breath to my weak amplifier.
So far I am wondering if I could do the following upgrades:
1. Add a JBL 2405 (any difference compared with the bullet tweeter 075?)
2. Also wondering if redoing the crossover with new components may bring improvements
3. The D130 is super shy in Bass, is it possible to put a port in the enclosure, or replace it with a modern cheap woofer and get quality results? I read the older D130 only handle 20W, so it's not recommended to put a bass reflex port, but I only have 1W of power and I am wondering if this might be a path to follow.
I just moved into Vancouver Canada, so I don't have tools to do a proper frequency measurement, I jut have a multimeter.
Do you see potencial to improve this so I can get the queality it has on the mids in a more extended range, keeping sensitivity high? What are your thoughts?
I love the look of classic and horn speakers, but also my main interest is to get better sound to listen to my music.
Many thanks in advance!
